With the first #GalaxyS6 devices released over two years ago, a lot of them has started to show signs of aging at this time. Apart from the common problems of charging and booting up, a lot of S6 owners have also reported having trouble with the screen. In this post, we cover this particular issue together with two others. We hope you’ll find our suggestions useful.

Below are specific topics we’re bringing for you today:
Problem 1: Galaxy S6 screen twitches when watching or playing mobile games
My Samsung is constantly twitching when I type something or watch a video or play mobile games. When the twitching happens too often the screen freezes. I have to put my phone off and then the twitching occurs again and again. Every video it freezes completely. Not the whole screen twitches by the way. It’s mostly the keyboard or parts of the screen. I already got the battery off. Do I need to buy a new phone? This is getting really annoying. Can you guys help me? Thank you for your time. ( since i’m writing this the phone froze 5 times). — Paul Jan Rietveld
Solution: Hi Paul. Every Android problem can be due to either software or hardware causes. In most screen-related problems, bad hardware is to blame but we hope that’s not the case here. To narrow down the possible causes, we suggest that you try the troubleshooting steps below.
Clear app cache and data
The first thing that you must do is to determine if the problem is being caused by an app-level bug. To do that, make sure to clear the cache and data of the apps involved. For example, if you’re having the problem when using a particular video app, wipe its cache and data and see how it works afterwards.
- Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
- Navigate down to Apps. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
- Once in there, look for the application and tap it.
- You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
- You should now clearly see the Clear Cache and Clear Data buttons for the application. Tap Clear Cache first, then observe the phone. If the problem returns, do the Clear Data option.
Clear the cache partition
Apart from being able to possibly fix your issues, clearing the cache partition is also a recommended preventive maintenance step. It works by deleting current system cache to force the phone to build a new one. This way, Android only uses up-to-date system cache when loading apps. This is done to minimize the chance of bugs arising from a bad cache. If you haven’t done it before, here’s how to do it:
- Turn off the device.
- Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
- When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
- When the Android System Recovery screen appears, release the Volume Up and Home keys.
- Press the Volume Down key to highlight ‘wipe cache partition.’
- Press the Power key to select.
- When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
Third party apps
Sometimes, an app can affect others or Android. If you tend to install apps without checking whether or not they’re from a reputable developer, it’s only a matter of time before you’ll encounter problems. To check if an app is causing the abnormal screen behavior and freezing, restart the phone to safe mode, then try to replicate the problem again. Here’s how:
- Press and hold the Volume Down and Power keys for 20 to 30 seconds.
- Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
- Your phone should continue booting up and you will be prompted to unlock your phone as usual.
- You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.
If your phone can play videos normally without making the screen to twitch, or the phone to freeze, that’s a clear sign that an app is causing them. To identify the cause, you must uninstall apps and observe the phone after each uninstallation. Uninstall, then observe. Repeat the cycle until you’ve determined the offending the app.
Reset the phone to its factory defaults
One possible reason for your problems may be an software glitch. As long as it’s not being caused by inefficient firmware coding, which means that the developer of the operating system has messed up with the codes, factory reset should be able to fix these temporarily glitches.
Factory reset will erase all user data like photos, videos, etc. so be sure to create a backup for them first. If you haven’t tried factory reset before, here are the steps to do it:
- Turn off your Samsung Galaxy S6 Edge.
- Press and hold the Volume Up, Home and Power keys together.
- When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
- Wait until the Android Recovery Screen appears after about 30 seconds.
- Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
- Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
- After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.
Have the phone repaired
If factory reset won’t fix the problem, contact Samsung so the device can be repaired or replaced. There must be a hardware issue behind these troubles.
Problem 2: Galaxy S6 edge Plus rooting issue, won’t load Android, blocked by FRP
Hi. My Samsung S6 edge plus was rooted to a custom ROM. i turned off the OEM lock in the developer option, now my phone is not getting switched on and displays a message on top left side of screen “RECOVERY IS NOT SEANDROID ENFORCING” AND “CUSTOM BINARY BLOCKED BY FRP LOCK”. I tried recovering it thru ODIN but the driver does not recognize. i have tried using different computers and different USB cables. i went to samsung service center and they say the motherboard needs to be replaced and it costs as much as half of the total phone`s cost!!!!! i cannot understand what could a software issue got to do with hardware??? please help me as my phone is bricked. — Dhruv7555
Solution: Hi Dhruv7555. Rooting or flashing sometimes lead to hardware problem because it can corrupt critical sectors of the storage device. This usually happens after repeated flashing or rooting procedures. This is one of the reasons why Samsung discourages users from tampering with the software.
To see if the problem can still be fixed on your end, try to see if you can reflash the bootloader back to its stock state. To do this, you must have the original firmware that came with the phone when you first unboxed it. Alternatively, you can use any stock firmware version for your phone model.
Once you’ve reflashed the bootloader successfully, you can then try to flash the stock firmware. If any or both of them won’t work at all, you’re out of luck. You can either have the motherboard replaced, or simply have the phone replaced with a new unit.
For reference, here are the general steps on how to reflash a bootloader. Exact steps may be slightly different for your phone model so use our guide with caution. Better still, consult other guides for accurate instructions.
- Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
- Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
- Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
- Proceed with the rest of the flashing procedure using the Odin program.
- In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
- Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
- Restart the phone once the procedure is finished.
Problem 3: Galaxy S6 files from SD card become corrupted, how to recover data from SD card
Hey, i need your help to solve an issue that started to happen yesterday. I have a Samsung S6, running Android 6.0.1. I have a Samsung SD Card Evo 64GB. Since yesterday all the photos I had on my SD card are not viewable. In other words, the files exist but the preview appears a black icon composed by an image symbol and an exclamation point. I used the file viewer and the files are stored where they should be in the SD Card. I executed the media Re.Scan app to try to fix the index, but nothing changed. I copied one of them to my laptop and I cannot see it also (Windows 10 tells me that “cannot open this file”). Can you help? Cheers. — Pedro Martins
Solution: Hi Pedro. The files must have been corrupted for some reason. To see if you can still recover them, you need to use an advanced recovery software that might be able to fix the broken files. If you’re lucky, you may be able to recover some or all of your files.
Recovery software files are expensive and are have often proprietary protection in them. They are usually used by companies specializing in data recovery so their tools are not commercially available. To avail of their services, you must be willing to pay a few hundred dollars.
And keep in mind, data recovery is not guaranteed. Some companies may still charge you even if very little or nothing is recovered. Be sure to know the terms before paying them for their services. To find such companies, use Google.
