How to Fix Samsung S10 Camera Not Working

Today we will share how to fix the Samsung S10 camera not working. Open the camera. The camera is not working. As the camera has been replaced before and the problem still occurs, we need to take out the motherboard for further testing.

Place the phone back down on the heating pad at 100 °C for 2 minutes.

Insert a plastic card and slide it through. Apply some alcohol to facilitate separation.

After the back cover is separated, disconnect the flex cables. Then yank the motherboard out. Remove the front camera. Disconnect the connectors and remove the back camera.

First of all, we check the appearance of the connector. The connector looks good with no obvious damage.

Next, we connect the red probe to the ground. Measure the diode values of the connector with the black probe. When measuring pin 58, the diode value is abnormal.

Open the bitmap. We find that the power IC supplies power to the camera. The failure of the camera is probably caused by the power IC. 

Next, we try to replace the power IC. Remove the shielding cover with a hot air gun at 380 °C and airflow 3.

Apply some paste flux to the power IC. Remove the power IC with hot air gun at 380 °C and airflow 3.

Then clean the bonding pads with solder wick. Clean the bonding pads with PCB cleaner.

Get a known-good power IC. Apply some paste flux. Flatten the tin on the bonding pads with soldering iron at 380°C. Clean the bonding pads with PCB cleaner.

Apply some middle-temperature solder paste to the bonding pads. Heat to form the solder balls with hot air gun at 320 °C. 

Next, we solder the new IC with hot air gun at 330 °C and airflow 3. 

After the motherboard cools, measure the diode value of pin 58. The diode value returns to a normal value of 520.

Then we put back the shielding cover and camera. Install the motherboard for testing. The camera functions well. That’s as far as today’s repair case goes.

A Beginner Guide (Why & How ) to Using Boardview Schematics for Phone Repairs

Today we will introduce the new REFOX boardview software. Boardview software is an indispensable tool for phone board repairs. The circuits on the motherboard are intricate. Sometimes it is very difficult for us to recognize each circuit just by the appearance. Moreover, there is no way of knowing the contacts of each component.

However, boardview software distinguishes and marks each component on the motherboard. It can help us determine if the components have contact, which can substantially increase the efficiency of troubleshooting.

We can get a lot of information from the boardview software. There are two main sections of the boardview software. Simply put, the bitmap tells you the location and name of each component, while schematics tell you what each component does.

For starters, we can know what the component is through the initial letter. C is the capacitor, J is the connector, R is the resistor, U is the chip, and L is the inductor. The color can tell you the function of each area. The gray areas are grounded while blue areas are empty with no use. The yellow areas serve as signal or power supplies.

Last but not least, we can quickly find the contact components through clicking one component. In the split view, by clicking one component of the bitmap,the schematics will automatically jump to the corresponding component.

In addition to the above functions, resistance values can also be viewed in REFOX boardview software. You can even define your own resistance values.

Next, we will show you how to use the REFOX boardview software with a repair case. The iPhone 12 won’t turn on.

Then we need to take out the motherboard for further testing. Heat the phone with a heating pad and remove the screen with an opener.

It can be seen that the area around the display connector is severely corroded. Clean the corroded area with PCB cleaner.

Install the screen and plug in the direct current supply. Prompt a boot-up with tweezers. The boot current is fine but there is nothing on the screen.

Then we measure the diode values of the connector and compare the measured values with the values on the boardview software. The measured values do not have to be the same but the differences shouldn’t be large. When measuring pin 14, the diode value turns out to be abnormal.

Open the bitmap and find pin 14 of the connector. Click it and we find it has contact with one inductor.

The inductor has been corroded away from the motherboard. Next, we need to install a new inductor. Open the split view of the boardview software. Clicking the inductor on the bitmap can bring you to the inductor in the schematics. Judging from the schematics, the inductor is 700HM. Then we need to install an inductor of the same value. 

In the first place, apply some flux and middle-temperature solder paste. Solder the inductor with a hot air gun at 380 °C.

After the motherboard cools, measure the diode value. The diode value returns to a normal value.

Then we put the motherboard back on. The phone turns on and that is a repair done.

As you can see, the REFOX boardview software is of great help to board repairs. To give back to users, REFOX boardview software has launched a referral program. You can earn free days and rewards by simply inviting your friends to subscribe to any plans from REFOX boardview software. Please feel free to visit refoxteam.com for details if you are interested.

Apple announced the iPhone 14 on 8 September 2022, and customers began receiving them on 16 September. Although some lucky people received it earlier than ordinary users.  The new iPhone 14 offers a host of new features, including a more powerful camera, a better display, and more storage. Overall, it is an impressive upgrade from the previous model, which is sure to appeal to customers.

As a tech company and enthusiast, REWA Tech has already received iPhone 14 as well as other versions. With this teardown, we will take a first look at the internal components of an iPhone 14 and compare them with the iPhone 13.

Apple's iPhone 14 comes in four different models: iPhone 14, iPhone 14 Plus, iPhone 14 Pro, and iPhone 14 Pro Max.

Display

In terms of display size, the iPhone 14 is identical to the iPhone 13 with some slight changes like different flex cables. While the resolution is 2532 by 1170 pixels at 460 pixels per inch, it is still better than iPhone 13.

Battery

Apple's iPhone 14 battery has a larger capacity than iPhone 13's. Compared to iPhone 13, iPhone 14 uses a 3279 mAh battery, while iPhone 13 uses a 3227 mAh battery and the battery life is also longer than ever.

Motherboard

It was widely expected that Apple would use the Bionic 16 chip in its iPhone 14. However, the Bionic 16 chip is only available on the iPhone 14 Pro and iPhone 14 Pro Max. Therefore, if you wish to experience the premium feel, you will have to spend more.

However, the iPhone 14 still has an L-shaped motherboard, although there have been some slight changes.

 

Camera

iPhone 14 features an advanced camera on both the back and the front, as well as great optical image stabilization.

In addition to a larger camera lens, the iPhone 14 has a different flex cable than the iPhone 13.

Is iPhone 14 easy to repair? 

It's good news for technicians that the iPhone 14 has a removable back glass this year. It is now easier for repair shops to repair an iPhone without having to disassemble the front glass.

Is iPhone 14 same as iPhone 13?

The iPhone 14 comes with some new features, but there are also a lot of similarities with the iPhone 13, such as the A15 Bionic chip, the same display size, etc. The main differences are the weight, thickness, battery life, and improved camera.

Is the iPhone 14 Back Glass removable?

The iPhone 14 and 14 plus are equipped with removable back glass. You can now easily remove the back glass from the iPhone 14 to repair it.

 

The Bottom Line

While the iPhone 14 comes with lots of new features, the iPhone 14 Pro variant is the best way to get a premium feel from the device. 

The iPhone 14 starts at $799 with some modest improvements such as a better camera, a longer battery life, a car-crash detection feature, and emergency contact via satellite. Although we hope you won't need the last two features. 

iPhone 14 Pro Teardown | Interchangeable Battery with iPhone 13 Pro

There is no doubt that Apple is the most innovative tech company in the world. Each year, they release new iPhones that are not only technologically advanced but also user-friendly and stylish. Many loyal Apple customers constantly look forward to getting their hands on the latest iPhone. Apple's success can never quite be replicated by other companies even when they release similar products. This is because Apple has mastered the art of innovation, and continues to set the standard for what consumers expect from technology products.

On September 8, Apple announced the new iPhone 14, and customers began receiving them on September 16. There are several improvements to the iPhone 14 pro, including a new design, improved cameras, enhanced dynamic island, and more powerful processors. An A16 Bionic chip powering it is the fastest ever found in a smartphone.

A lot of new and enhanced features are only available on iPhone 14 Pro and Pro Max. In the iPhone 14 pro and Pro Max, Apple has introduced a dynamic island, which is a wonderful feature for tech enthusiasts.

iPhone 14 Pro Teardown 

The iPhone 14 and 14 Pro have already been torn down by REWA Tech and their videos have been posted on YouTube. The purpose of this article is to provide a more comprehensive overview of the iPhone 14 Pro and its components. In addition, we will see how difficult it is to repair an iPhone 14 Pro.

Phone Opening Method:

Many YouTubers laud Apple for making it easy to open the iPhone 14 and 14 Plus, but the iPhone 14 Pro and Pro Max are difficult to open. The iPhone 14 and 14 Plus are easily accessible from the back, which is good news for third-party repair shops. On the other hand, iPhone 14 Pro versions cannot be opened from the back. The display must be removed to repair the phone, which is risky for most repair shops. Apple will charge $499 for replacing the back glass, or you can use the Refox laser machine to repair it.

However, you can easily and effectively open it with our REFOX RS50 Mobile Phone Opener & Clamp Fixture.

iPhone 14 Pro Battery

Apple's iPhone 14 Pro has a slight improvement in battery life. In comparison with the iPhone 13 Pro, iPhone 14 offers one hour more video playback.

As we disassembled the iPhone 14 Pro, we discovered that the iPhone 14 Pro battery appearance and flex cable are identical to the iPhone 13 Pro battery. 

We discovered that the iPhone 13 Pro and iPhone 14 Pro batteries are interchangeable, which is good news for repair shops.

iPhone 14 Pro Camera

In the iPhone 14 Pro, Apple has improved its camera to 48 MB, which is a significant update. With this camera, you can take a 12MP photo that contains more details. You will be able to capture better photos and videos, and you will be able to zoom in more without losing quality.

In terms of design and appearance, the iPhone 14 Pro camera is the same as the iPhone 13 Pro camera. The camera on the iPhone 14 Pro is bigger than that on the iPhone 13 Pro, and even the sensor is bigger. During the iPhone 14 Pro camera teardown video, we tried to show you the differences between iPhone 14 Pro and iPhone 13 Pro cameras.

Dynamic Island

Apple always has something innovative to offer with its iPhone pro models, and this year was no exception. Notch has been replaced by Dynamic island, which appears modern and innovative. The dynamic island is a new and innovative integration of software functions that shows you current activity in progress and you can check alerts and much more.

iPhone 14 Pro Teardown Video

Which iPhone Models Feature Dynamic Island?

Currently, Dynamic Island is only available on iPhone 14 Pro and iPhone 14 Pro Max. It is expected to be available on all models of iPhone 15 in the future. However, the iPhone 14 and 14 Plus still has a notch similar to the iPhone 13 in their design.

Can I exchange the iPhone 14 Pro and 13 Pro Batteries?

The battery and flex cable of the iPhone 14 Pro and 13 Pro was tested in REWA's lab and found to be identical. Additionally, we showed how to replace the iPhone 13 Pro battery with an iPhone 14 Pro battery in our YouTube video. The device, however, will display an "unknown part" message in the settings. This can be fixed by replacing the IC chip. 

Is the iPhone 14 Pro back removable?

iPhone 14 Pro and 14 Pro Max features non-removable back glass which makes it hard to open the phone to repair. In this case, you need an iPhone back laser machine to back glass disassembling.

Can iPhone 14 Pro be Repaired?

Touch Screen Technology & All you Need to Know

Mobile and computer technology are constantly changing due to technological advancements. In the past, we accessed the main device using external gadgets such as a mouse, keyboard, and other peripherals. But the invention of touch screens made it easier to interact with mobiles, computers, and other devices.

What is a Touch Screen?

Simply speaking, a touch screen or touchscreen is an input device that allows users to interact with the main device. Users can manipulate their devices using single or multitouch gestures. A touch screen display has three main parts: the protective glass sheet, the digitizer sheet, and the LCD panel.

What is a Touch Screen Digitizer?

A touch screen digitizer is also known as an LCD digitizer. The digitizer is an integral part of every touchscreen display. A touch screen digitizer is a thin transparent sheet or piece of glass that converts analog touch into digital signals. When a user touches the display to process something, the display transfers the command to the digitizer, which converts it into a digital signal.

What is an LCD in Touch Screen?

The full meaning of LCD is Liquid Crystal Display, and LCD is one of the main components of touch screens. LCDs (Liquid Crystal Displays) are super thin and fragile components inside touch screens that display images. It is only possible to get to the LCD by disassembling the device.

Brief History of Touch Screen

According to Wikipedia, the LG Prada, which was released in May 2007, was the first mobile phone with a touch screen. However, after the iPhone was released in 2007, the touch screen became wildly popular. 

Different Types of Touch Screen

It is not necessary to use an external mouse and keyboard to operate the touch screen. Keyboards and mice are replaced by touch screens. However, there are five different types of touchscreen monitor technology. They are listed below

  • 5-Wire Resistive Touch screen
  • Surface Capacitive touchscreen
  • Projected Capacitive (P-Cap) touchscreen
  • SAW (Surface Acoustic Wave) touchscreen
  • IR (Infrared) touchscreen

Use Cases of Touch Screen

In the last few decades, touchscreen technology has revolutionized the way we interact with technological devices. More and more devices are coming with touch screen displays nowadays, and we can see them everywhere. Below is a list of the most common touch screen devices:

  • Mobile phones
  • Laptops and Computers
  • Tablet computers
  • Watches
  • ATM (Automated teller machine) machines
  • Point-of-sale (POS) terminals
  • Car navigation systems
  • Medical monitors

It is possible to use touch screen displays anywhere. This is a very convenient way to interact with the machine.

 

When Should I Replace Touch Screen?

You can break your favorite phone with just a drop. However, if your phone screen is broken and not responding, you will need to replace the display screen with a digitizer assembly. If you are lucky and your touch screen works, then you only need to replace the front glass. A front glass replacement is less expensive and easier.

Conclusion:

Mobile phones these days are almost all equipped with touch screens. Smartphones with touch screens are stylish and beautiful.

REWA Tech is a leading supplier of cell phone parts and tools. Our company offers high-quality LCD and OLED screen replacements for a wide range of smartphones. For your desired screen replacement, please visit our shop.

How to Fix iPhone Keeps Restarting

For what reason does my iPhone continue to restart, and what do I do about it? We trust our iPhones and they need to work constantly. It would be great if there was a solitary reason behind why iPhones restart again and again, yet there is certifiably not a magic slug for this issue. In this article, I'll disclose what makes iPhones keep restarting and I'll tell you the best way to fix the issue.

For what reason Does My iPhone Keep Restarting?

iPhones that continue to restart for the most part fall into two categories:

1. iPhones that restart discontinuously: You can use your iPhone for some time with no issue by any means, and afterward your iPhone unexpectedly restarts.

2. iPhone restart circle: Your iPhone consistently restarts and it's unusable. The Apple logo shows up and vanishes on the screen, again and again.

Assuming your iPhone falls into the subsequent category, skirt ahead to step 5. It's difficult to do the initial few steps if you can't utilize the software on your iPhone.

1. Back Up Your iPhone

Before we do any troubleshooting whatsoever, ensure your iPhone is backed up. If your iPhone has a hardware issue, this could be your last opportunity to back up your information. If we want to, we'll restore your iPhone in a later step, and you need a backup before you restore.

Once you're backed up, you'll be prepared to begin fixing the issue.

2. Update Your iPhone's Software (iOS)

Like Windows on a PC or macOS on a Mac, iOS is your iPhone's working framework. iOS updates consistently contain heaps of fixes for programming bugs and different issues. Once in a while, a software update fixes the issue that is making your iPhone continue to restart or enter a restart loop.

To check if any software updates are available, go to Settings - > General - > Software Update. If an update is available, install it.

You can also connect your iPhone to your PC and use iTunes (PCs and Macs running macOS 10.14 or older) or Finder (Macs running macOS 10.15 or newer) to update your iPhone's software. If your iPhone is consistently restarting, iTunes or Finder may be your smartest option.

3. Decide whether An App Is Causing Your iPhone To Restart

It's extremely intriguing for an application to make an iPhone restart or turn on and off more than once. Generally, the software on your iPhone is protected from issue applications. That being said, there are over 1.5 million applications in the App Store and they're not all perfect.

If you installed an application not long before your iPhone entered a restart loop, uninstall that application and check whether the issue settles itself.

Settings - > Privacy - > Analytics & Improvements - > Analytics Data is somewhere else to check for issue applications. It's typical to see a few sections in this rundown. Quickly scroll through the list and search for any applications that are recorded again and again. If you see one, uninstalling that application might fix your iPhone.

4. Reset All Settings

Reset All Settings is certifiably not an enchanted shot, yet it can resolve specific software issues. Go to Settings - > General - > Transfer Or Reset iPhone - > Reset - > Reset All Settings to restore your iPhone's settings to factory defaults. You will not lose any of your applications or information, yet you will have to enter your Wi-Fi password once more.

5. Remove Your SIM Card

iPhone restart loops can be caused by issues with your iPhone's connection to your wireless carrier. Your SIM card connects your iPhone to your wireless carrier, so removing it is the most ideal way to troubleshoot issues where your iPhone continues to restart.

Sit back and relax: Nothing can turn out badly when you remove your SIM card. Your iPhone will immediately reconnect to your carrier when you set it back in.

If removing your SIM card fixes the issue, put the SIM card back in your iPhone. If the issue returns after you put your SIM card back in, you'll have to restore your iPhone (step 7) or replace the SIM card with your carrier.

On the off chance that removing the SIM card doesn't fix the issue, don't put your SIM card back in until you've finished the subsequent step.

6. Hard Reset

You shouldn't do a hard reset on your iPhone except if it's totally necessary. It's similar to switching off a workstation by unplugging it from the wall. That being said, an iPhone restart loop is one of those times when a hard reset is justified.

To play out a hard reset, hold the power button and Home button simultaneously until your iPhone screen goes blank and the Apple logo reappears.

On an iPhone 7 or 7 Plus, the buttons you need to press to execute a hard reset are somewhat unique. At the same time press and hold the power button and the volume down button.

Assuming you have an iPhone 8 or newer, the process of hard resetting is also different. Press and release the volume up button, then, at that point, the volume down button, press and hold the side button.

Notwithstanding what model iPhone you have, ensure you hold the two buttons down together for no less than 20 seconds.

If you removed the SIM card from your iPhone in the previous step, this moment's a decent opportunity set it back in your iPhone. We've eliminated the possibility that your SIM card is making your iPhone restart. Ideally, the hard reset will fix the issue where your iPhone continued to restart, yet on the off chance that it proceeds, you'll need to reset your gadget by adhering to the guidelines underneath.

7. Restore Your iPhone

Restoring your iPhone eradicates and reloads the iPhone's software (iOS), and it can dispose of a huge number of programming issues simultaneously. At the point when we restore your iPhone, we'll eliminate the possibility that a software issue might be making your iPhone restart - that is the reason Apple specialists get it done so regularly.

Your iPhone should be connected to a PC to restore. I suggest doing an exceptional sort of restore that Apple specialists do call a DFU Restore, which goes further than a normal restore and can tackle more issues.

After the restore gets done, you'll have the option to reload all your data from your iPhone backup in iTunes, Finder, or iCloud. If you still have an issue, return here and continue to peruse

.

8. Check For A Hardware Problem

Hardware issues are a typical reason why iPhones stall out in a restart loop. If you're utilizing a case on your iPhone, remove it before you proceed.

Intently check out the charging port on the lower part of your iPhone. Verify whether any trash is stuck inside and for indications of corrosion.

If something doesn't look right, snatch a toothbrush you've never utilized and delicately brush out the charging port. A short circuit or other issues inside the charging port can cause a wide range of issues with your iPhone.

9. You May Need To Repair Your iPhone

We've eliminated the possibility a software issue is making your iPhone continue to restart and we've checked for hardware issues outside of your iPhone. Assuming your iPhone is in a restart circle, your iPhone likely should be fixed.

If you decide to find support at your neighborhood Apple Store, ensure you have an appointment with the Genius Bar so you don't need to stick around.

Summary

By this point, I wish we'd fixed the issue that made your iPhone keep restarting. I would like to hear your experience and questions in the comments section below.
