S21 Touch Sensitivity - Samsung Galaxy S21 Questions

While gaming on shooter games,in less than 5 minutes into the game, i noticed the touch sensitivity becomes really bad like up to 50% decrese in touch sensitive, even after turning on the increased touch sensitivity settings in the settings app, its still bad
Is there a way to fix this

[Q] Why should we change Touch Sensitivity?

I've searched long and at any places, but nowhere was an answer. Everybody goes crazy if we talk about sensitivity, but what are the benefits of a higher sensitivity really?
I mean, here on mother earth, you can't get something better, without decreasing other features...
So if i turn the sensitivity higher (or lower), i mean if its more precise... Where are the disadvantages?
Higher battery drain?
Please help me to understand
I you slide you finger over the screen it takes a small distance before the phone reactes and moves the part of the display. Try it and you will notice this small distance on the homescreen. It is like a dead zone where you move your finger but nothing happens.
With the toch sensitivity fixes or apps or scripts you can decrease this distance to 0 or any other value. I think a value around 5 is quite common. I am not sure but I thought 15 is default, so you usually want to decrease it.
A disadvatage is, that if you set it too low, the phone might recognize klicks a swipes.

That was the answer i wanted! Thank you!
On some older kernels, when your phone is on ac power, the screen becomes very unresponsive. That's why people came up with the need to change the touch sensitivity.

[Q] hardware related screen (backlight) flicker problem

Hi folks
I have just changed the mainboard from my TF201 with one i bought off ebay (TF201 with badly damaged screen).
Now i have a heavily flickering, dark screen. The flicker goes evenly over the whole image, that turns on and off, so i assume it's the backlight. The brightness resembles the lowest setting. The screen flicker frequency is dependent on the brightness setting. Lowest Setting: about 4 on-off-cycles per second. Super IPS+ Setting: i would say about 25/second (still a noticable flicker, but the tablet is usable).
When there is just little stuff to draw on the screen (like at the "power down?" message) the flicker becomes even less noticable (ie. faster) while the brightness stays low.
The problem seems to be on the mainboard, because both my screen AND the broken one work just fine on my old board.
On close inspection I found a tiny burnt out IC close to where the WIFI-related circuits are on the board. Please take a look at the attached pictures.
It's a weird place for a display-related IC, but everything, including WIFI works absolutely fine. It's just the damn flicker. So maybe this is connected?
Anyone an idea / solution? Maybe even an app/kernel that messes with brightness settings?

Anyone noticing screen flicker?

Not only do I have light bleed but I'm also seeing screen flicker. I really want to keep this device but I'm getting sick of this...
The first thing I noticed when I turned on the device was the light bleed. Its pretty bad, and I normally don't mind those types of things. No flicker here though.

I noticed if I turn up the brightness it goes away.
I don't have light bleed, but I do see flicker if the screen brightness is turned down. It's reminiscent of the original Nexus 7, which had the exact same problem.
I have the flickering too...really annoying. I was hoping that this would replace my iPad but it's not looking good. Although lollipop is pretty amazing so far.
Does it only happen you adjust the brightness? If so, i dont think its a big deal as long as it doesnt happen during actual usage.
I noticed the flicker issue when I first was using it. I then turned off auto brightness from the main settings and started using Lux Auto Brightness and the issue has been resolved as far as I can see. I suspect this is an issue with the Lollipop build's brightness manager and not a hardware issue from the backlight. Also as far as bleed goes, there is apparent bleed when viewing the screen at an angle and looking directly at the edge, however I have found that it is a complete non issue in normal use (even in a fully dark room), which stands in stark contrast to my Nexus 10 which has noticeable edge bleed when viewed straight on.
No Flicking here
No flickering here either.
No flickering, but the auto brightness is very weird! It goes from extremely bright to extremely dark without me actually moving, same light conditions?
No flicker here!
Well, I guess we can all admit screen flicker is of the norm of Tegra.
Im seeing flikkering too.....
Only when brightness is low.
Remind me why Google/htc did not decide to use a 64 bit Qualcomm processor instead? :-\
Do you think that this issue can be solved via software update, or is this issue hardware related, and therefore cannot be fixed easily

considering that not everyone has it
So i say no
This issue seems to be related to auto brightness/adaptive brightness: The same brightness level set manually doesn't flicker.
Seems to be a software issue to me, and it seems highly likely every Nexus 9 flickers with auto brightness on (and at low relative brightness setting) in low light environments.

But, my screen flickers when I am on a constant brightness level. But, it doesn't show up as much when the screen is on at full brightness, just when the screen is at half brightness or just below half.

I guess we aren't experiencing the same issue, then: My screen only flickers with adaptive brightness enabled in low light conditions, seems like it is constantly readjusting the screen between two brightness values.
My Nexus 9 doesn't flicker at any constant brightness setting.
Yep, my Nexus 9 flickers as well.
About 15-20% brightness (fixed). It doesn't flicker all the time and it goes away if you change the brightness level or even by itself if you change the app you are using.
This leads me to believe this might be a software issue (N7/2013 had this too when it came out).

wakeup behavior

Just received my Gear S and love it so far. I have one small issue though. When I turn my wrist to turn on the screen, it comes on yet is a little dim and i have to swipe or touch the screen before it becomes responsive or is fully lit up. Is this normal behavior to save battery?

Figured it out. If you set it to wake to last screen it will wake up to full brightness.

Screen sensitivity slows down while gaming

PUBG mobile runs smooth on the phone without a single lag, the only problem is the phone sensitivity suddenly slows down while playing and i have to constantly reset my graphics its been weeks now. Any solution?
