My touch screen works fine except for the lower part of the screen. The portion that is not registering is the part where the quick launch icons are as well as the "back" and "options" button on the bottom. This started happening after a little rain got on it. I took it apart and tried cleaning all of the connections with isopropyl but I am still having this issue. Are there any connectors or anything else I should look for to help resolve this?
Thank you!

Im having some trouble with my physical touch buttons. They seem to stop working every now and then. If I bash the phone on my hand a few times they usually start working again. I'm guessing theres a dodgy connection inside somewhere thats causing this. There are no other symptoms though so it's very specific to the touch buttons.
I've opened the phone to have a look if anything looked loose but on the face of it everything seemed fine. However, I wasn't sure which ribbon was for what and couldnt find a diagram anywhere on the net after a quick search. Can anyone help identify what all the connections are for? In the picture I have circled the 5 main connections. So far I have figured the following:
Black circle - touch for screen
yellow circle - metal docking contacts on back of phone
red circle - not sure possibly speaker/touch buttons?
blue circle - not sure possibly speaker/touch button?
green circle - vibration motor?
If you know better please correct me. I think the touch buttons either work off the screen touch responsive connection (black circle) or the red or blue circles but cant quite figure out which.
Thanks
i know the gold colored part on the bottom left of the phone is the digitizer connector, is the rest of the screen working? if not make sure the aforementioned connector is pressed down securely

you mean bottom left in the picture I uploaded?
Everything else is working fine, no issues with screen whatsoever, its just the touch buttons. Thats why im trying to figure which connector does the touch buttons

yup
not sure whats up in that case mate, i have been taking apart my phone for the first time also, i messed up the signal coaxial cable connector on the bottom right and had to install a new part lol
It seems that there are some dead sensors or something in the upper right hand corner of my screen.
I'm getting these 'phantom touches' that keep pressing whatever is in that corner.
I'm wondering if there is any way to turn this part of the screen off, so it doesn't continue to register touches that aren't actually happening.
Does anyone have a solution for this issue?

Not possible bud, you have to replace ur touchscreen with a new one.

Okay, that kinda sucks. I guess it is kinda old after all. Thanks for the input though!
My cousin used to have this problem, she couldnt touch some parts of screen So she needed to use her phone on landscape mode
In order to see what parts have problem on play store write toucscreen test etc
No software solution
it's a hardware problem ..Your touch screen needs to be replaced
Hello, so...
I got this phone and because of broken screen Ive changed the glass part with digitizer. Now the digitizer is acting... weird. Like the screen is divided horizontaly and the upper part is changed with the bottom one and its also mirrored. When I pres down left corner, the dot of touch appears at the top right etc. Is this because I somehow f**ked up the flex cabels or can this be recalebrated? Ive tried to disassemble and connect it again and also resetting the phone to default and then flashing whole rom again but nothing helped. Any ideas?
I was having the random shutdowns on my Moto360 Gen 1. I replaced the battery and the shutdowns are gone. Problem now, the bottom half of the screen is unresponsive to touch. Swiping from the Top, Left, and Right work fine. Anything from the bottom half doesn't work or respond to touch. What did I screw up? Any kind of touch sreen Calibration to fix or did I pinch something on one of the ribbon cables? Any help appreciated. Thank you
Have you managed to fix it? My watch is presenting the same problem
It started with it being hard to press 1,q etc keys on keyboard. When I enter developer settings and enable pointer location ,I realise it doesn't register at least hundred pixels on entire left and right sides of screen. Quite annoying. My gf phone is slowly going that way also.. any ideas apart from replace screen or phone? Also around entire edges of phone it looks like screen is delaminating,i.e. a lines and checkers pattern shows....
I have the same problem. It started with a crack, when the phone was bent too much (see picture).
But the unresponsive left edge started later, after I had fixed the phone in a car cradle. Probably the cradle held the phone too hard.
I noticed it because I was using gesture navigation and I couldn't use the back gesture when swiping from the left side. The right side still works in general, but in some apps I have a problem on the top right edge with the 3 button menu button.
You can check your touchscreen in the hardware test menu (*#*#6484#*#*) with test 8 Touchpanel edge.
Also test 7 ITO fails for my device.
Sorry, I have no advice for your problem.
My personal solution for this problem is: I will dump this device, which had hardware problems right from the start (like bluetooth disturbing WLAN) and lots of software bugs, which Xiaomi is not willing to fix. Instead a Pixel 4a will be my daily driver in a few weeks.
My problems also started after bending the entire phone.. was looking at replacement lcd and frames but in reviews they seem to not have proximity sensor..maybe just get a new phone and have this as backup..
