hello i have just gotten an tmobile g2, this is my second one, the first one had bad pixels, but anyways. i have noticed that the screen on the g2 seems a little low. like the colors are alot warmer than that to my hd2. so i guess we can call it that the screen has Color Saturation is this how the phone is suppose to be? or is there a problem? or is there a way to boost the backlight ? (yes i have brightness 100% question is can we get it past 100%)

[Q] Does the note 10.1 (2014) use PWM at all level of brightness?

Hi, my english won't be very good because it's not my native langage.
I'm very sensitive to the flicker caused by PWM (Pulse Width modulation) wich is a technique used in the backlighting of a lot of LCD display to dim the brightness of the screen. I'm a "migraineur with aura" wich is a neurological disease, so like epileptic people my eyes and my brain are very sensitive to all sort of visual stress even the most subliminal one like PWM used at a high frequency. And I wanted to know if the note 10.1 (2014) use PWM to dim the screen at all level of brightness? I m' sure that it use it a least until 50 %, and that it is not PWMed at 100% brightness. Cause at 50% i'm sick litteraly within second, and at 100% i'm ok. But I have not tested all the level between 50 to 100 cause if it's flicker I can have quite a serious seazure, which would leave me ill for days, so it's quite hasardeous for my health. So what i'm doing is that i leave the system brightness to 100% wich of course is too bright, but I dim it with a soft (screen adjuster) that can dim the display without touching the backlight. But it's not a perfect solution cause the display is still using a lot of energy that way and there's a lot amount of blue wavelenght coming from it and i'm sensitive to blue wavelenght too. Basically as you can see, LED backligh is not a very good technology for epileptic people, eye-sensitive or migraineur. (I personally think it's not a healthy tec for anybody)
So, I just wanted to know if someone know if there's an "official" level where the note doesn't use PWM anymore to control the brightness of the screen, I mean below 100? Thanks in advance, and i'm sorry if my post can sound a bit confuse, it's not easy to try to ask and explain something in a langage that's note your native langage. Thanks in advance.

Galaxy tab s 8.4 t-700 lcd screen issues

Hi, maybe someone have encouter similar issue and have and could comfirm if there could be anything else i could do except replacing whole lcd+touch, which cost pretty much same as new unit
My my screen is showing some weird artefacts on screen, at first there is not much but its getting worse after few muniutes of use. If i lock and unlock the device i show white light bleed on left side of the screen (first picture) then if i lock again, wait for a while it disappears, but some artefacts and color pixel start to show on left side (second pic). After a while some strong white lines apear, always in the some spot, but if i put down the device for few minutes it desappers. Reattaching battery didn't help, i guess thats not the case. Could this be a faulty LCD connector? Or the screen is dying.. ? Definitly not a software bug, i just upgraded to 6.0 and even in bootloader mode while upgrading there were those two lines (last pic)
What screen brightNess do you use. It's recommended to use 20% to avoid screen burn in

Hmm.. since i usually use the tablet in bright locations its probably set to higher then 50%, at least..
There is one more thing, after like 10 minutes of use, almost all the above issues stops, only thing that stays is the "burned like" vertical stripes, barely visible, on about 2/3 of the screen.
I does not make the table unusable but its quite annoying...
could this be affect of screen burn in ?
i think its just a bad screen from a begining cuz i have tab s 8.4 for almost 2 years now and i gave it to my brother for a year and he was in Tenerife...temperatures there are high so i doubt its a screen burn since my tablet is still ok even after one year at Tenerife with probably brightnes always on 100%...just sharing my xperiance cheers guys

full brightness issue?

I've noticed in the last few days if it's sunny out when using the phone outside the phone puts the brightness up to MAX and I get green, yellow lines all across the screen. If I manually lower the brightness a little it's all ok again. I imported the AL00.. I'm guessing Huawei won't fix it as it's an import... Anyone got any ideas?

No ideas but I noticed the lines too. It was a really bright sunny day and snow around. The stripes could be seen on the white screen only. It came as a huge surprise cause I haven't noticed any other screen error or malfunction. And screen test passed without any problem.
Same for me.. Only outside and with majority of screen being white. Normally they show up when unlocking and dissapear after a second or so, I think when I start to scroll or similar.. no one else?
It's one of the oled downsides. Check it with 5% grey picture or search on youtube to 5% or 10% grey test.

The first screen in that topic is what I have too on my Mate20X. It's a gamble. If you return it and swap it, you may get a worse unit.
