I recently changed my screen touch because it was broken
And now screen is much less sensitive ...I have to tab some times to select something
But for some reason screen works perfect on cold surroundings (like in winter season or while sitting in an a/c room ...yea it again stops responding if it gets heated up a bit after some time heavy use ...I got the idea of increasing sensitivity from this threadhttps://forum.xda-developers.com/xperia-u/u-development/fix-increase-touch-screen-sensitivity-t2608102
Please help me
Thank you

hey hey hey,
okay so, i'm having my very first problem with my tab 3 10.1 gt-p5210.
at approximately 64 degrees farenheit the screen goes dead meaning no touch registers.
i experimented with holding icecubes and touch works normally, humidity doesn't seem to be a factor,
warming my fingertips with lighter doesn't work either, only when i walk in to house from screen porch
does screen responsiveness return and almost immediately. any thoughts?
I got this White HTC One X from a friend who dropped it in the waters.
It boots up just fine, the digitizer works, as well as... partially... the screen
Now i got the data from it, so mission accomplished in terms of data loss. He gave it to me for free so i rooted it with the bad screen.
So now i have this rooted phone running latest stock ROM.
The screen's brightness is too low even though the brightness settings is set to maximum. After a hellova lot of testing i found out that when the device is cold, the brightness increases when i turn the screen on. And when the processor is running (ie opening an app, or rendering animations), the screen's brightness starts to get lower and lower until it just completely shuts off.
What i did was put it in the freezer to make it REALLY cold, and it works just fine for like 5 minutes until the CPU gets hot again and the screen turns black.
I tore it down, and changed the screen, but the problem is still there, so it must be some part of the motherboard.
I won't change all the motherboard because honestly i don't want to spend that much money on something older than my nexus 4
So if anyone can tell me what part exactly is responsible for the brightness IN THE MOTHERBOARD, so that i can find a way to keep it cold, it'll be very much appreciated.
PS: I can see and control everything from PC too when the screen shuts off... so i can still practically try and do anything with it. Also, the actual LCD screen is cracked and black on it's right and bottom half, and it's currently "half open" (ie i can see the Nvidia CPU, and the vibration motor under the screen)
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
Warranty expired a long time ago. No visible screen damage (some chips on the sides), it was dropped a lot unfortunately.
One morning I woke up and my phone had a strip of 1cm dead touch screen at the top (it was partially under the pillow so there was some pressure involved, like everyday though). So I enabled landscape gyroscope transition mode and it turned out to just be a minor inconvenience.
But now it developed another issue (after another drop), earlier the top of the screen was completely dead no matter what. Now it has expanded downward by an additional 1cm but it's not exactly always dead and the bottom 3cm has also become semi-dead:
It can still work if I hold my finger in place for a few seconds, and it seems to work perfectly fine so long as the touch originates from elsewhere on the screen - it tracks perfectly if I lead it into the semi-dead touch zone. I do not know enough to even guess how that happens, initial touch detection differs from touch tracking?
I do not know enough about touch screen technology to know why this is happening and what it means, I do not want to buy another phone - I have considered just buying another G3 and performing a motherboard transplant but I thought I should ask here first about this. Can it be fixed by me with an easier method?
Hi All!
I just got a new a70 5 days ago, it's performing very well, but i did notice one thing. Sometimes my quick touches when i just very quickly and barely touch the screen, the touch is not registered. I activated the factory diagnostic mode (*#0*#) and tested and got some interesting results. If i touch the screen quickly enough, the touch is not registered at all, even though i apply a substantial force. I can do this like 3-4 times out of 10 if i really try. I also tried it on my galaxy S5, and although I could reproduce the same issue, it was much harder to get it to miss a touch than on my brand new a70. I did try it with and without a screen protector and it didn't make any difference. I'm actually surprised, I didn't think I can touch the screen too quickly so that the sensor (or software?) fails to register it. My question is: is this an expected behaviour, or something that should be looked into? It doesn't really affect everyday use, but ever since i discovered this I'm now always having this weir feeling anytime i'm about to touch the screen that "is this touch going to miss?". So my questions are the following:
1. Is this behaviour normal?
2. Why does my S5 seems to be more "reliable" and is harder to get to miss a touch.
3. Is there a 'minimum touch duration' for these capacitive screens?
4. Anybody else who has A70 experienced this, could try it out?
(it was not very easy to reproduce at first. i started noticing it when i wanted to open messenger chats, that some of my touches missed. for the issue to be easily reproduced one would have to try and tap as quickly as possible, so that your finger touches the screen for the shortest time possible)

Yeah the touch on this device is horrible. Don't listen to fanboys, this device has a couple of issues other than the touch screen having an awful response time.
Check:
+
The SD675 isn't well optimized for most games, so it lags in most of them, while on the A50's weaker processor, the Exynos 9610, games work just fine. Most of the time, they work better on the A50 than on the A70.
And there's another issue with dark colors being turned off instead of dimmed, because the screen doesn't know the difference between "dark" and "totally black". I'm gonna demonstrate this later by comparing the A70 and A50 side by side.
The A70 has a stronger CPU than the A50. The A50 has a stronger GPU than the A70. The A70 has better battery life.
That said, yeah touch problems. I notice it all the time when browsing. Trying to tap on small links are not registered most of the time. I have to zoom in.
I believe it to be a hardware issue that is not fixable in software.
