x98 plus Guide: PWM screen flickering work around !

Hello,

Another guide from me , actually a tweak to solve the very annoying flickering issue with the screen of the x98 tablet with Intel integrated graphics chipset. You can easily detect this if you point the camera of your phone toward the screen.

The reason of the problem is called PWM which is set to only 200hz in our tablets as default. You can find exhaustive explanation of the issue here: http://www.flatpanelshd.com/focus.ph...&id=1362457985

And the solution is actually very simple: increase the value of PWM to 4000hz (yes much much more than the default value) with this great open source Windows program: https://github.com/tpurtell/PWM

Now our screen will not flicker anymore, I can set the screen light value to 25% and have the same level of colors contrast, without the need of playing with the brightness control of Intel (that would result in a loss of contrast).

Enjoy your new screen!

TWRP screen flickering - unable to fastboot

Hi all, I am a novice and would appreciate some help.

In the processes of flashing a rom I erased the whole tablet using the Wipe option in TWRP. I then flashed a rom using adb sideload successfully however there were some errors message regarding unable to access certain folders. From memory /data was one of them and there were others. I then reboot to recovery again, tablet restarted, showed TWRP and screen looped on and off showing TWRP logo, like it was trying to load TWRP. Seems like i need to create these folders again.

How to avoid the AMOLED flickering?

I've recently bought the 9.7" version of the Tab S2. I was aware of how unrealistic and oversaturated the AMOLED display is on default setting, but luckily this can be turned off, so it was the very first thing i did (though now the white balance is off, but at least it is not oversaturated).
Unfortunately i wasn't aware the fact that the display at below ~75% brigthtness flickers. The lower the brightness the more disturbing it is. And it drives me crazy. I hate the flickering cheap cr*p LED light bulbs, i hate that most notebook screens with LED backlight are non PWM free, and are flickering And after having this tablet for three days, i am hating it too. I frankly believe these products should be banned, because it hurts your eye, and your brain. I thought when we said good bye to CRT monitors, flickering screens will never be an issue again. Unfortunately they are :/

After googling the internet i found this article gs5.wonderhowto.com/how-to/eliminate-screen-flicker-lower-minimum-brightness-android-0157760 but the solution unfortunately requires a rooted device, wich would trip the knox and void the warranty, so it's a no no for me. Then I found several other apps on the play store which are doing the same without requiring root access: drawing a black overlay over the screen and you can set the transparency of it, so you can get a lower brightness without the flickering, because your screen brightness is around maximum, the lowered transparcy of the black overlay makes it less bright. Unfortunately none of these apps work like the one for the rooted devices, wich has a second slider at status bar, so instead of the brightness you can change the transparency at the notification screen. The non rooted apps i found do not work this way, they don't have the extra slider, you need to tap them, so you can get to where you can change the trasnparency and that's very uncomfortable. I tried so far Darker and three other Screen Filter apps, but none of them works with a second slider :/ Also using the Screen Filter apps when there is a smooth color transition on the dipslay (default background picture for example) gives ugly end result. Using a Screen filter app might reduce battery life so i might need to charge it more often (i don't care), but since the display is not flickering, it is always on, it might will burn in faster (i do care, i intend to use this tablet for 3+ years) So i am currently in debate wether i should return this product and get my money back or not. It is a really great device, but this terrible flickering of the AMOLED screen makes me super unhappy, wish it had an IPS display :/

If this is an issue for you too, and you found a Screen Filter app with a second slider at the notification area (without requiring root permissions) please let me know.
