Poco m3 touchscreen failure - POCO M3 Questions & Answers

I just got my poco m3 from Aliexpress and noticed that frequently the touch fail on the sides of the screen. Like when I hit the back arrow on the top left or the "?123" button in the gboard. It feels laggy and if i'm typping fast then hit the ?123 button usually dont recognize the touch and I have to hit 2 or 3 times. Can it be the glass film that's reducing the touchscreen sensibility ? I'm afraid of remove it and have to return the phone later without the glass.

Might be faulty or just lagging. The first few version of the rom was super slow

Mine doesn't have this problem, and I am using a glass screen protector.
Edit: I am using Google Zhuyin Input, I just tried to type really fast in it, and pressed "?123" after typing fast, it only went to the numpad when I pressed it the second time, so I think this should be normal. But the back arrow on the top left corner always works on my phone, I tested this with Google Play.

I noticed that when i'm typing with the phone on horizontal this doesn't happen, its weird. I think some parts of the screen are not working well. I'm gonna have to return the phone.

Guys, I think this has to do with a setting "Prevent accidental touch on the edges" or similar i saw earlier but now I can not find it anymore in the Settings app

My POCO M3 also has this issue, and I notice there are two area (red box in picture below) exist this problem.
If you press "q", "a", then press "?123" in fast speed, the "?123" button will not respond.
If you press "p", "l", then press "↲" in fast speed, the "↲" button will not respond either.

hi, i am also having this issue and was wondering if this is any software issue or hardware issue.

Apparently its a common hardware issue in the screen. If I type with the phone in horizontal the issue doesn't occurs. I just got used to it, didn't want to replace the phone cus it takes a long time to the phone to get at China and return to me cus the post service in my contry is horrible.

yes, i think this is a common problem among not poco but whole xiaomi devices as per this thread
https://www.reddit.com/r/Xiaomi/comments/haf1f9

It's interesting that so few people report about this issue. I gave the phone to my gf and she didn't realize any problems, although the phone had shown the same issue.
Either most people simply don't recognize it as a problem, think they are hitting the wrong button, or the problem is a rare issue on certain phones.
I took a video showing the issue on my Poco M3. I have contacted the support and send them the video, too, but only got the standard reply (update software, use safe mode, blahblah).

Any update can solve this problem? Please brother tell me. i am also suffering this problem

I also have the same problem, unfortunately I broke the screen so the service center will probably reject my case

Black lines on display when screen freezes

Since a few weeks, at an increasing rate, my screen tends to freeze completely. This usually happens while entering a program, or after a few seconds when I'm playing music in the Windows Mediaplayer. It also happens when my Wizards wakes up when I receive an incoming call.

Some remarks:
- no overclocking installed
- sometimes the things displayed start 'shaking' a little before it shows the barcode
- music continues to play, and thus the wizard itself doesn't freeze
- when I push the 'on/off' button to make the wizard go standby the black lines dissapear slowly
- when I push the 'on/off' button again the lines have vanished and the wizard works just fine... but usually it freezes up again after a very brief moment
I've re-installed the ROM, even different ROM's. Nothing seems to work.
Who knows what this problem might be?
If you've done a hard reset and it doesn't make any difference, then I'd say it's a hardware problem and you need a new phone.

Mine is also from T-Mobile (so it actually is an MDA Vario). Mmm, sucks. Hopefully I can turn it in for a free repair.
Hi,
I've just got the same problem on my T-Mobile MDA Vario.
I'm in the UK and tried to contact UK T-Mobile but I've received no further response after telling them that I bought my phone from Ebay and I was not their account holder.
Can anyone have an advice? Thanks!
BUSPBP
My MDA Vario has also started doing the same. Can somebody please help??? :'(
As far as i know it is a faulty connector tape between main unit and screen. should be easy to repair in any service point. i have the same problem as i mentioned here:http://forum.xda-developers.com/showthread.php?t=321078

How did you figure out it is the connector tape?
Because thing like this occurs ONLY and INDEED ONLY as a result of damaged connector tape.
I haven't read about a single device with this symptom that had this problem caused by something else tham connector tape.
Thanx. Will have to look for a place where they would repair/replace the connector. Funny thing is, only MDA Varios seem to be exhibiting this problem.
Nope, I've got an xda mini s (o2) and the same problem. Mines only goes fuzzy when the keyboard is not open, but it is very annoying.
Btw.. as for the faulty connector tape between the main unit and screen, is there anywhere this can be bought?
I have the same problem and have diagnosed it as the connector tape too. So far I have not seen them available anywhere. I did ring up PocketPC Tech in the US and they said I would need to replace the screen (presumably because the screen is sold with a connector tape assembly too?)..
I find I can solve the issues by turning the device off and holding the LHS of the housing down on the LCD slightly. Then I can turn it back on and it's ok. I also tend to find the problem occurs more frequently when the device is cold (poorer connection I assume).
Mine Fades to White
Hello everyone.
My HTC Started doing the same (Fading to white on wake).
I never had this problem before. It happened when i updated the ROM; from the original WM5.1 to 6.1.
As i'm not the technician here; you shouldn't take my opinion as granted.
It can also be the screen "tape"; since my HTC TYTN has a minor scratch on the Screen Tape.
To solve this problem i do 2 things:
1- If it didnt stuck; press the power button to put the device in standby; and then press it again to wake up.
2- If the device went stuck; remove the battery at least for 3 sec. and boot it to the bootloader. (also figured that when it doesnt boot with the boot loader or else; it can be "revived" with the usb cable plugged in; and doing the bootloader step).

Faulty Xperia - Ideas

Hi guys, I appreciate that this may not be the correct Forum but I get alot of knowledge from this site so if you guys dont know, no one will!!
My Xperia optical pad/joystick is having a mare...each time i rub my finger over it, my X1 trys to dial out and skips to menus. The phone has apparently become "moist" acording to the Vodafone shop (Which to me seems like an excuse)
I ahve wiped the device back to factory settings and the same errors keep happening. I have turned the Opt Pad off in settings but the pad still reacts to touches and just jumps though menus and try's to make calls!!
Is there a way that I can get this fixed or resolved or has anyone else got any ideas. This may be a hardware fault.
Thank you all.
Well I can imagine dust being behind the scroll 'wheel'. How about you try to blow it out with a can of compressed air?

Hi,
Thank you, I have used a can of air and this seemed to make little difference.
Maybe I could get the device apart and give it a pro clean although I feel the actual joystick me be capput :/
Other ideas?
Thanksagain.
Moist? The only way I can see a phone becoming moist is either from a bit of rain or sweaty hands. Either way, phones are designed to withstand this otherwise they would be completly useless for outside use..

I have the same issue. It does seem to happen more when I have been using the MobiPocket Reader to read a book for a while ... maybe my sweaty thumb is causing the issue ;-)
Seriously though, if this is really true about moisture I may have to trade my X1 in, it drives me nuts when this happens.
Is there a way to clean the optical joystick properly? (I'm going to try the air-from-a-can idea as well)

Autoscroll, the best feature in Mobi

Nah, AutoScroll just irritates me , get distracted for a second and you lose your place.
I've resorted to using 'tap the screen to go to next page' option. Seems to work well BUT the point is the X1 shouldn't have this issue.
Vodafone have offered to 'repair' it for me, since it's still in warrenty, but it means sending it away for 10-14 days and in the meantime they can give me a 'loaner' which will of course be a peice of crap (I'll just use my TYTN).
Update:
I have found the issue! After looking on Google I came across a YouTube video of how to dismantle and reassemble the X1.
Turns out one of the transistors on the Optical pad circuit board had become slightly coroded, so I cleaned this up with a small soft brush and a minute drop of meths and put it back together and BINGO!
Also while the screen was out I left it overnight in airing cupboard in a ziplock bag with a pack of Sylica(Spelling) Gell.
Search YouTube for: "Xperia assemble Front/Back" User; CKY1
Hope this goes to help someone.
Cheers guys
in my case, I just adjusted the joystick to lower sensitivity...It worked without surgery..
so technically vodaphone was right. and it was a moisture problem.

Desire HD Screen Issue

Hello all and thanks for reading my thread.
I have searched high and low for this same issue, but found nothing similar anywhere unfortunately.
I have recently noticed that at all times, the screen seems to produce some horizontal lines which flicker often ... I am finding it hard to explain the problem itself, but I have not dropped the phone nor hit it or w/ever.
All I can think of is that I played a lot of this one game on it and it could have affected (overheat?) the GPU or something along those lines...
I am really not sure, but bottom line is that now I see all these issues on the screen, and camera and some games are off limits to use as they look very confusing...
Anyone has any idea what it could be?
G
Could you provide a screenshot?
It does sound like a hardware issue. I would send it for repair. They might even replace it. Maybe you could take a video of it happening.
(I assume you tried uninstalling the game and it didn't solve the problem. If your CPU is being overclocked try resetting it back to normal.)

Are screen issues/hardware issues fully covered by warranty? As I talked to an HTC support dude and all he said was we can book a repair and if it's not covered by warranty we'll send you a quote, £20 if you don't want the repair, if you don't pay either we'll get rid of the phone in 3 months...
So I don't wanna really send it off then find my parents get a £100 bill of which they don't know of :/
Most likely the lines are caused by a malfunctioning LCD. This can happen on its own or by physical abuse. Carrying your phone in your back pocket can cause this. If the phone looks great on the outside (no sign of big nicks from being dropped or warped from carrying it in your pocket) then HTC should find no reason to not fix it under warranty. Sometimes things go bad on their own.
Hey,
thanks everyone for your replies. I tried installing a different ROM (Cyan) on my DHD and it still seems to have the same issue, tried changing the cpu and gpu voltages, playing with temperatures etc, but to no avail..
I guess the LCD did go wrong, so Im sending it to Vodafone (UK) for repair. The only thing is that they will probably send me a refurbished phone if they cant fix it which wouldnt really be my first choice, but oh well! Could be worse I guess...
Thanks again for all the feedback

[Q] Wildfire Screen Issues....HELP!!!

I have a weird problem with my Wildfire's screen after I did an OTA upgrade to Froyo.
First, the top of the screen stopped working. The taskbar wouldn't work and I the top wasn't responding. All of a sudden, after approximately a month or so, it started working again.
It worked fine for a few weeks and then the right side of the screen has a problem. All of a sudden it started automatically hitting the spot on the screen where the letter "P" would appear on the keyboard. When I was trying to type out a message, the letter "P" would get hit on its own over and over again. When the keyboard was not open, it would still happen.
I felt it might be a virus, so I did a hard reset. This still didn't stop. So I switched off my phone and kept it in a desk for 48 hours. When I switched it on again, this problem stopped, but the right side of my phone was not responsive (approximately 4 milimeters of it).
I can see that this is clearly not a hardware problem and has something to do with the firmware/OS. I'm not too sure what to do. I've tried flashing new ROMs on to my phone, but it remains the same way.
Incidently, when I tried flashing "TheNextSense" ROM on to my phone, the phone started hitting the portion of the screen where the "P" key would appear. When I switched back to CM7, it stopped, but the right side was unresponsive.
Is this something to do with the memory? Or is this a known issue with upgrades/certain ROMs?
Any help will be appreciated. This is driving me crazy
why do you think its not a harware problem ?
for me it sounds like it is one. (temperature or short circuit problem)
IANAHRM (I Am Not An HTC Repair Man) but I think the touch screen connector has just slightly worn loose, perhaps due to temperatures. It sits on the right side of the main board (left side of the phone itself). I know the Wildfire can survive quite a motion shock so that shouldn't be it (I hope).
Nandroid backup and restore jobs heat up my phone quite a bit, did this occur on your device as well while you were installing roms? That might explain the change in behaviour.

Nope. It's never heated up till now. This happened all of a sudden, and it gets worse with upgrades. It's like, for some reason, the phone isn't able to function properly with any ROM other than the stock ROM. I'm going to try to put back eclair on it today and see whether it works. Will keep you posted.

Because it doesn't always occur. It kind of gets fixed on its own after a few days. It's like my phone has a ghost in it
I put back the stock Froyo ROM and now the problem is 50% better - much of the portion of the screen that was dead earlier is now responding. But the rest still isn't. Any ideas? :-(

[HELP] OnePlus 5 - weird LCD problem

Greetings dear people of this forum!
Few days ago my phone's display started behaving in a very weird way (could be a minor drop down).
When I press the power button to draw the pattern, the whole screen is full of disturbed horizontal lines (pic_1).
If I apply some pressure on the screen's bottom right corner (pic_1 - red dot) it gets back to normal and doesn't even flickering at all (pic_2).
Howerver as soon as the display goes off because of the turn off time, too close to the face when making a call or just switch it off with the power botton, the problem reaccures.
I am very sure it is hardware related, because on the screenshots there is nothing like that and it is persist in the boot sequence. In my opinion this is some kind of faulty connection, I have already take the phone apart to catch any loose connector, but nothing changed after that.
I feel like I have to buy a new screen, but I hope I can repair it somehow, because it can works very well after my acupuncture therapy.
I have bought the phone second-hand, and I know there was a screen replacement, so its not the original one.

Could also be any gaps or something that can cause the lines(display gets pressure from wrong installation).
2 options basically. Loose connector or faulty LCD.
I don't think it's software related.
If you can give it back, then you should. If not, then you can either try to fix it by yourself by replacing the LCD assembly (with the touch digitiser).

Yes, You were right, as I thought too. The reason behind the problem was the LCD.
I have replaced it and now it works like a charm.
