Touch screen unresponsive at the very bottom - Xiaomi Mi 8 Questions & Answers

All of a sudden the lower part of display (about 7 mm) has become unresponsive to touch which means no more gestures (swipe up to get to home screen is not working) e struggle to use the classic navigation buttons.
Sadly I had the same issue in my mi5 but in that case phone had the issue since the unboxing.
I'm starting thinking the xiaomi touchscreen tend to be more fragile than others.
Now I'm waiting for gearbest support.
Anyone has any advice or similar experience?
I made a screen recording

Regarding Xiaomi Quality
While climbing into my truck, I dropped my Mi8 from a height of about 4 ft on accident and it landed flat on its face , on the concrete. Freaked out, I left it laying their for about a minute fearing that the screen had been smashed into a million pieces. However, I picked it up to see that it was fine, and not a single scratch. So I immediately went out and bought the Love Mei 360 case.
Anyway, regarding your touch issue, you should really provide more some information about how this issue came about, what rom were you using, did the phone get wet, etc.
Also, I had an issue with my Mi8 soon after unlocking the bootloader where the top part of the screen would not register my touches, I first tried recalibrating the screen using Miui hidden settings app, the test is called QMMI ( I think) and if I remember correctly there are several menus of testing that also calibrate the screen for me this worked and for good measure I reinstalled a Miui rom and havent had the issue since.
Try it, hopefully that is the only issue. If you are using a AOSP. It's possible that you have a driver issue. So before sending the phone off for service its worth testing.. If you are on stock and still have a locked bootloader, I would try resetting the phone before trying anything else.
Good Luck.

Some gravedigging, but the question is still on the table - have you managed to fix it?

Touchscreen issues

I've experienced some serious touch issues in the past two days. It's happened very randomly and I can't replicate the issues. The screen losses touch sensitivity and I can't do anything, then it randomly comes back after 10 seconds only to animate every touch I made during the 10 second lull.
Has anyone had any touch issues like me?
Edit: disregard this post. got the forums mixed up with another device.

sounds like a software glitch, is anything eating up the processor?
I'm on LRX210 out of the box. I haven't had any battery stat app running but nothing unusual is going on in the regular battery app
I have this issue as well. Drives me nuts when I'm playing clash of clans. Found a sprint forum post that says it could relate to screen protectors? I have an invisible shield on right now.

I have a screen protector but I've never had issues with it before. The touchscreen is COMPLETELY unresponsive 100% of the time

Have you updated to 5.1? Since 5.1, there were significant changes that appear to have been made to proximity sensor that seem to be affected by any sort of screen protector that may cover it. If your protector covers the sensor, then I suggest removing it.
I haven't. I currently have the notification on my lockscreen (since I can still use the power button and view that basic info). It simply just stopped working while I was using it. Going into the Sprint store early this afternoon
My N6 arrived yesterday and was immediately unusable. The keyboard filled in a ton of garbage when I was asked to first enter my name ... Power cycled to try again and have had nothing but reliability issues with typing at times the screen will lock while trying to type (no response) or assume I've clicked when I haven't which makes accurate data entry impossible.
wiped, reset and upgraded software from 5.0 to 5.01 to 5.1 - had to remove my ATT sim which initially blocked this process and reset. Issues are still present seems like the screen is defective.
Support has issued an RMA to return the device after suggesting they would replace. Not a great start.
im having the same issue with my nexus, i went back to stock, not even rooted anymore, still doing it, its driving me nuts..
RMA. It's quite obvious you have a hardware problem.

I'm actually not so sure that it is. I've seen this issue intermittently across 3 different devices, but only on 5.1.1 firmwares.

Although we're in an pls thread, I tend to agree. If it was a hardware issue, I don't think we'd see the OS acting out the touches later.. It means the hardware actually accepted the input but the OS didn't do any thing., Likely an OS hang or something.

Touch Screen Issues

I've started to have touch screen issues the past few days.
Any idea what may cause it?
Sometimes, when I touch the screen, say in settings, I touch one item, but a different item is selected somewhere randomly on the screen.
Happens in TWRP as well. If I select options to wipe, it will select others, and then it doesn't swipe over to execute the action.
No ideas? What would make touches appear where I don't touch, even on TWRP?
I tried the keyboard calibration on HTC's keyboard.
Any ideas? Screen protector?
It comes and goes.
I can't believe no one else is having this issue now.
I don't do stupid things with my phone, like drop it, put it in my pocket and sit on it, and wash it with soap and water.
Since I've started running Lollipop, it appears that my case is causing this issue. I've never had this problem before.
However, I updated my wife's phone to Lollipop Sense and now she is having the same issues with a different case.
Take the cases off, and they work more responsively.
I can only chalk this up to being a Lollipop issue, and hope it will be fixed soon.

I opened another thread about a similar issue I'm having after Lollipop. My gesture launch randomly stops working and I have to reboot. No other issues for me though. I have an anti-glare screen protector on mine, but had no issues before the update. I've thought about a factory reset to see if that would cure what ails.
I'm on tmo but have the same exact issues. This is what i've found so far...
I turned on the developer options and turned on show pointer. This will show you where the touches are landing.
If you scroll down slowly, you can see most of the touches are in line (up and down) and not random on the screen.
I've removed all programs that have screen overlays (screen filter, twilight etc)
I've removed the cases thinking they might be causing the issue, but removing them only slightly improved the issue I thought...
Sometimes its hard to reproduce the effect, its not consistent. So this leads me to believe that it could be a process that's running in the background that calls attention at the moment you're touching the screen, and then refocuses the screen to your point of contact. And in between it thinks you're moving your finger when you really aren't.
In any event, I can't find the exact cause of this. But, it definitely started after the update to lollipop. I had none of these issues before. I even got the phone exchanged because I believed the digitizer went bad or something. But this issue exists on my original phone, its replacement, and now on my wife's current phone and that phones replacement (across 4 phones).
I'm currently working on my wife's replacement (4 or 5 non-oem programs installed) and continue to have the problem. But it is not consistent as I can't readily reproduce it.
What i've done to try and learn more is when I see the screen pointer light up in random places, I keep pressure on the screen so I can observe where the screen is registering contact. It almost looks as if it's trying to pull down the shade. Whether it be because of the dual points of contact and it thinks we're swiping down, or because of another program that is stealing focus for whatever reason.
If anyone else has insights into this, please let us know as this is more than frustrating! I keep calling people in hanouts with a lot of people and they aren't happy about it lol.
Also for reference, we're using ADW ex launcher instead of Stock HTC Sense. But even when I remove ADW (uninstall) and run sense, it continues to happen. So it's not that.

Touch Issue

I am using one plus 3T last 18 days. It is one of the greatest phone i had ever seen. i am very happy with the phone but my problem is about touch sensitivity or touch problem. From the very beginning i download an app from play store which name is screen touch test. i saw that when i draw a line any where or normally draw something, every where it works fine i mean touch is perfectly registering but only when i touch right corner to the down side then it not respond. I have to touch there several times then it shows dot in apps but other corners dot are showing perfectly when touched. but if i draw a line from that corner or any where then it respond immediately. sometimes this corner works well. i never installer curved glass but using Nillkin H+ pro tempered glass. i bought it from china and am from Bangladesh. is it a software problem or hardware if hardware then i have to go for good shop. but it is not possible for me to go china. please revise my problem its urgent.
How is the touch working without a screen protector?
Are you actually seeing this problem in real day-to-day usage, or just the screen test app? Wondering if it's a case of looking for problems where they might not exist . . .
I never used without screen protector
No actually i think this problem will not be affected for others but some time when i touched that place it not respond. but if it is a problem then i should know because for this problem i think it could be affect my display. Thank you for this response.
Well, assuming you have similar problems in any app. And it's not just the testing app that sees this.
You have to test without the screen protector to eliminate it as a cause to your problem.
If it's the same without any protector attached then my guess is your touch screen is faulty.
But I would still start with a clean install to see if that fixes the problem since that is a less time consuming and cost free troubleshooting step, than sending it in for repairs and having them find out a reinstall fixed it.
But my question is if my screen is faulty then why it response when i draw lines but only create problem when that area is being touched. but if start touch from place and come to this point then it also works fine.

Sensitivity issue

Hi there,
my Redmi Note 9 NFC version has a problem with its touch screen. For me, it is too sensitive, which means my finger hovers about 1 mm above the screen an the phone detects a touch, which is clearly wrong. That leads to wrong typing and all sorts of other annoying issues.
Does anybody of you know how to turn the screen less sensitive? The tips I read on the Internet are not applicable to the Note 9 or are simply useless.
Your input is highly appreciated!
Thanks!!!

If you searched the internet and found no one facing that issue on the same device then it might be just your unit with this problem. Anyways your phone has a warranty and contacting Xiaomi's support is recommended.
Sorry, don't think I can help you - I haven't come across this problem. Just tried to reproduce it myself but can't. Are you using a screen protector? If not, you might find it helpful to use one - they tend to dull the sensitivity a little, though if you're getting touches detected without any contact being made I suspect a screen protector might not help
that's unfortunate that no one has the same problem, which means it could be a hardware problem, which means I need to return it or take it to a service center.
I'm using the original screen protector, didn't tear it off. I had hoped there was some internal feature within the CIT, for instance, that I can use to recalibrate the touch screen, but it merely checks the touchscreen.
Hmmm, need to think about it a bit more.
I also have this problem , . I have a Redmi Note 9 pro EU version . My finger gets registered about 1 mm above the screen . Although I don't seem to have a problem with typing, it is annoying as sometimes the screen registeres my finger without touching by the screen witch leads to all sort of problems , ( like wrong friend requests on Facebook )

Question Touch Issues

Is any One Facing Touch Issues on Moto edge 20 pro device.
Check 987043122 post on the topic about Gpay, he talks about touch issue on Chinese model.
I bought mine in Australia and have the same issue. ehhh... Going to be a pain if I am going to have to go through warranty and all.
Hmmm... Just tested my own device (Edge S Pro) and couldn't reproduce the issue with Touch Screen Test app. Swipes near front camera (hole) work without any apparent issue. I'm using a GSI by the way and I didn't test this on stock FW before flashing (since the issue was not known at that time)...
Though I think if you're using a screen protector (including the built-in one) it'll definitely cause some issues when swiping near the front camera as there would be a hole around it.
Don't know if Google has guidelines that apps should not avoid displaying near the "notch" area, but some games on Play Store do put borders around the screen to maintain a 16:9 aspect ratio (which may not be the same as avoiding) so they're not affected as there would be nothing to press/swipe near the front camera. I recall having read that at one point Apple did have such guidelines (not sure how it is now).
I've just purchased one and I think I'm having issues when using the keyboard. Notice few times.
I'm having issues with my device.
Swiping from right hand side of the lower quarter of the screen, sometimes I get no respons.
Touch issues on the edge 20 and Pro is widely known, and known by Motorola. There is a software release that solves it ending with Q3-19-86 for the edge 20 pro.
It has started to rollout. I have recieved it, and it solves my problems, even with tempered glass applied (where the troubles was most visible before)
Motorola has added a function (under screen settings- advanced) to improve touch screen sensitivity when using glass protector + Optimized other touch related code.
Can't wait for the update...also having the problem with touch, in auto mode as well as 144hz. It is dependent on the brightness of the screen - most likely to occur when above 70% (which for this phone is alot of the time), and I found that temporarely it is fixed if I turn the screen off and on again. The problems are sluggish response to touch, right swipe not working, ghost touches on link that I scrolled over, bunch of stuff opening up unwantedly, typing produces multiple same characters. Hope it is fixed, I really like this phone apart from that.
