Touchscreen or Software Issue?

Hi guys! I just upgrade from a Nexus 5 to S6 Edge. I am having an issue with this new phone not sure if it is affecting everyone or just me... :/
I am having an issue to swipe on some applications. One of the application is Swiftkey. I find it very hard to swipe to delete whole word. (You need to have Swiftly Flow disabled.) My music player (ZPlayer) i also hard it hard to swipe to skip songs as well. Is it just me or everyone is having this issue? I have used those touchscreen tester application and find my touchscreen to be fine.

Hey man, I'm having the same problem, definitely a software issue as I tested the screen via *#0*# and it's working.
Any updates on your end?

No solution so far but just living with it... I am surprised that this matter is not noticed by many users yet. :/

Had a problem with swipes being interrupted and taps registering multiple times. Got the screen replaced through warranty and the problem is gone. The problem seemed to be caused by pressure making the digitizer make contact with some other part causing erratic touch response.

Display Touch Delay.

So I got the Sony Xperia SP today (Isn't really a new phone for this day but it's better then the old S3 mini) and I rooted it.
So everything went well (isn't the first device I root) but there is something that I really hate on it.
The touchscreen by it self has some kind of delay.
I turned on show touches, and I started up a game were you cannot afford any delay, the game is called VOEZ.
So after I touch a "note" in the game, I fail every single one because when I tap on the screen, it takes like a half second to register my touch.
Is there any way to get the delay lower or get rid of it? (For example, the s3 mini didn't had any delay and it's older so I guess there is some way to do it?)
Thanks.

Well, the delay might be caused by the ROM you're running.
Does the delay present on the ROM before you rooted it?

I found the problem by my self after searching for a bit longer.
For some reason the delay was there because in the display setting was Glove mode chacked.
I fixed it now. Thanks.

And just for your knowledge.
The Xperia SP has a known bug, that it doesn't recponce on touch when it's on the horizon (like when its on the table)
For me flashing CM13 from stock fixes that problem

COR-L29 8.2.0. 131 - Weird touchscreen behavior - Please Advice

Hey everyone,
I recently bought my new Honor Play.
First night I noticed something but didn't have time to investigate it any further.
When my device is laying on the table or bed I can't fully control the screen (top and bottom).
For example:
I want to bring my notification/settings area down and its not reacting (using cut-out, tried full bar ... same result).
Neither is the navigation button (using 1 but tried it with 3 ... same result).
The weird part is that it's happening only if the device is laying directly on something (table/bed/box/etc.).
I assumed that it could be something with gyroscope, but when the phone is horizontal in hands (tested with compass gyroscope 0°) everything is fine.
Ok i guessed it could be a few things, so here is the list of what I already tried:
fingerprint scrolldown notification X
smart & automatic rotation X
unwanted pocket call accept X
different notification bar settings X
different navigation bar settings X
different themes (original x usermade) X
different screen settings (FHD+/ HD+; small/medium/big text and view mode)
-
everything with/without protective case (product ID : 51992528)
I noticed it the first night (sunday) and since then i received two or three updates and it's still the same. Now I'm a bit worried it can be a HW thing.
OR
Could it be from a protective glass ? On second thought I dont think it is when its OK when not laying on smthing...
Thanks everyone for advice!

Have you removed the screen protector to verify that? I would advise you reset the phone after that. Don't forget to backup your data.

Is it one of those glove mode or pocket mode things?

Tried both. No effect.
Anybody with Honor Play who can try it?
I'm wondering if it's just me.

Sounds like a poor grounding of the display digitalizer. I’m afraid it’s a hardware defect. Mine has no problem detecting fingers when it’s on a table.

I can't reproduce your problem with my Honor Play. It's in a case, no screen protector though. It acts exactly the same whether it's lying down on a table or I'm holding it.

I have the same thing, bought a 15€ screen protector so I ain't peeling this off..
Gotta take a look from the settings. Will update on it soon.

Me too I am having this weird touch behavior and I don't know whether it's a hardware issue or a software one

Note 8 sensors not working

Hello there!
Well just like the title says, I have a Note 8, wich is almost like brand new, not even one drop to the ground, not a single scratch, and also no funny apps, just the basics for everyday.
Thing is out of nowhere, several sensors stopped working, no matter what (factory reset, hard reset, wipe cache, safe mode).
Fingerprint scanner: WORKS
Proximity sensor: DOESNT (calls never turn screen off)
Iris scanner: DOESNT
Auto bright: DOESNT
Auto rotate: DOESNT
Heart rate: turns on, but doesnt register your pulse
I've read a lot of people having this issue, some say it was right after a security patch OTA, other it's a faulty batch of motherboards, yet no definitive answer.
Do anyone knows if this can be fixed? It can't be a hardware problem since its like brand new, unless the update somehow fried something inside...
Hope I was clear enough about this, any ideas you have could help!
Thanks!

Did you perform HW test, USSD code *#0*# in phone dialer?
May be useful to report your phone model (Exynos - N950F or Snapdragon-N950U or other)

Yes I did. Everything is stuck at 0.
Oddly, today I tried the heart monitor again, and it registered almost 50%, and then says finger is not where it should be, not reading anymore...

mi 9 multi touch problem

My mi 9 seems to be able to only detect 1 finger. Completely wiped phone and problem still persist. Anyone with same issue or able to fix issue?

I have the same problem. Have you found any solution?

youtube.com/watch?v=dLa-oHLig7U

I have that same problem. Could you help

Happened the same issue to my Mi9. Multi touch was working normally but suddenly it stopped working while I was zooming on a web page. Then I made a factory reset but still didn't work. Today I updated to Miui 12 hopping the problem would be solved but still no success. I think this bug is related to Android 10 as I saw elsewhere someone rolled back to Miui 10/Android 9 and things got to normal. On the other hand this is not a hardware failure for sure since multi touch keeps working normally on apps running in game turbo mode.
So, has anyone found how to kill this annoying bug?
Thanks for any help.

ive been searching everywhere how to fix this. i already email xiaomi about this issue. still didnt find clue how to fix this bug. still hoping that xiaomi will fix this issue.

This issue is a shame for Xiaomi!
As far as I know the only solution is to downgrade to Miui10 and stuck on this version or take the risk to upgrade to Miui11 (not recommended for obvious reasons) or the fresh new Miui12. So far I've been using the "turbo game" thing to workaround the bug. I had to install some alternative apps from Google Play (such as Chrome Beta, other gallery app, Google Maps Go...) to use instead of the stock apps so I can use them with "turbo" and get pinch to zoom working. This is not the best way to solve the issue -- the ideal is to get multi touch back working again without the need to resort to any tricks -- however it works very well. Maybe one of these days I'll get some patience to setup the good old Miui10 again...

i also have this ghost touch on the upper part of the screen. it came same time as the multi touch issue. it cant even fix by game turbo. i cant even play games normally like moba or fps game. i dont know if its just me have this ghost touch issue. its a big shame for xiaomi flagship phone?

No news about this issue? Everything works fine with Pixel Experience in my MI9 but multitouch. I remmember I solved another problem (auto-rotate didn't work for the display) and I solved it flashing only last version of "persist.img".

Same here bro!
I bought my Mi 9 in February and everything worked well. I also upgraded to MIUI 12 with no problems at all, then suddenly multitouch stopped working.
If I flash Pixel Experience will the problem be solved?

No way, Installing PE doesn't solve the problem.
I'm going to try it with new kernels and FWs.

Try to flash MIUI 10... I read somewhere it should work, because MIUI 10 is built on Android 9, which doesn't have this issue

same i have this issue, i tried miflash. the only workaround are miui 10 and game turbo method.
also i have this nonresponsive part of the upper screen, right where most game analog button placed. idk if this "dead touch" is connected to this multitouch issue

This was the first and probably the last Xiomi I bought. Back to iOS. Bought a second hand iPhone 11 in mint condition. Working rock solid! Crap Mi9!!!

Have the same problem here!!!
Upper screen DEAD
Annoying ghost touch on upper screen
Have to type multiple times because It keeps ghost touching...
Can't sell the phone, because of these issues...
Miss my Galaxy note

Is there a fix to this issue now? GameTurbo enhances the touch so that multitouch works. There must be a fix to this.
