Touch Screen issue after May Update! - Google Pixel 4a 5G Questions & Answers

Hey guys,
I am back to the real OG forums of Android after spending a few good years with iOS devices. Ngl, missed this place a lot!
So I have been using a Pixel 4a (5G) for 2-3 weeks now, and everything was perfect until the May security update 2 days ago. Although, previously, there were a couple of touch screen issues observed by many anyway, a friend too who uses the same phone, same variant g025-e and we used to observe extremely **** typing experience while charging our phones, until this update, literally destroyed the whole experience for me specifically, and not my friend.
This update was about 16.9 mb and on the night of 1st of May, I put my phone to update and slept, within hours it was released. The next morning my frustration begins. There is a part of my screen, specifically between the app dock and home screen separator that doesn't work anymore. There is absolutely no damage to the phone, neither have I dropped it or anything. The whole "asd" row on my qwerty keyboard barely works. Tapping the letters on that row a million times might register a touch magically, but you get my point, its just extremely frustrating.
Furious, I immediately took it to Pixel Community (Pixel Community Post here) and I haven't received a reply there yet. I took it to Reddit (Reddit post here), and there isn't any help either.
I have run a couple of tests on my phone testing my screen, and to my surprise multi-touch isn't working either (I can't zoom into photos, can't use maps or anything for that matter) and my phone only detects one finger. Attaching screenshots below where you can see touch break (there is no point of posting multi-touch test here, it can only show its detecting 1 finger, and that also breaks in the area shown below):

As last resort, I have also tried removing my screen protector, playing with the screen-protector mode in the display settings but in vain.
Now I am thinking something definitely went wrong while my phone installed the update, and thinking of a full fresh flash of the Software after unlocking the bootloader. Please suggest what to do. Hoping for positive replies. I am not doubting the hardware because my phone just stopped working right after the update, even though the new update suited my friend's phone just fine.

Oh damn I'm sorry its that much for you mate. Did it happen after the update or just randomly?

the day I updated the phone, the touch screen started to not answer again on the top and then the problem is repeated gradually on the rest of the screen. I just made a factory rest, the touch screen no longer works, I will change the screen .

X1 optical joystick problem

Good day everyone
i'm using my X1 since about 2 weeks.
I recently did notice that after waking my phone up the "scrolling down action" is performed...so the optical joystick thinks i'm moving downwards but in fact i'm not even touching it...it not only happens after waking it up, but also when i want to scroll upwards it happens often that it's sliding downwards again when i release the touchy surface...
cleaning of the touchy surface didn't help...aswell as adjusting the sensitivity of the optical joystick...
does anyone else have that problem...or anyone out there having an idea how to fix?
mine dont have that problem at all and if hardreset dont change it i would
write it off as a hardware malfunction
Some solution?
The does same thing happen to me?
I had this problem before too. Somehow, while i was at school, i must have shaken it a lot or something, because i had P.E. that day. When i got home after i had p.e., the joystick scrolling problem stopped. I had the X1 in my pocket the whole day, so i guess when i was running in P.E., something must have shaken and the problem is now fixed.
This has happened to me only once, while browsing. It fixed itself after a soft reset. Very weird.
Solution!!!
Mine had a very similar problem. It was making calls alone once something just touched the joystick's surface. I took it to a repairing center (with a little hope once i read above comments). However they repair it, well, at least the joystick is working on its scroll funtion but when I press it nothing happends. They told me that it was repaired by just cleaningl, with paint thinner and a gum eraser, the part that is marked inside of the red circle in the image below.

Mine's got that problem too.. It was so annoying that I disabled the optical joystick thingy... Don't need it anyway
Im glad i dont use that optical thingy. Its annoying when you want to press center button on D-pad but then accidentally scrolls up or down.
Sorry for poping in this post again after er.. i think this is like a year old post. I just had this problem last month.. or maybe months. I been ignoring it for some time now but well it is getting annoying (It always make the speaker go louder for some odd reason by scrolling up or while searching for a contact it scrolls up). I have never used the d-pad and thought of disabling it but not sure how too.
No more warranty as I bought it for some time already (They said so), I send it back to the shop and they wanted to charge me MYR200 to change the ribbon. After thinking a while that d-pad only cost like $7.99USD which is MYR25.10 from cnn.cn website.
Do they mean the slider flex cable which cost MYR147.619 (After converted)?
Does that has any relation with my D-pad getting stuck at the up button?

[Q] Can I recover this LG G2 ? Snow on screen(see pic)

I got this phone the other day, It's just got snow all over the screen (it's out of warranty) so I opened the cover, pulled off all connectors and re-seated them (didn't remove any boards, just what was accessible once the back covers were off.
I am new to Android but, this model I have replaced 2 Displays on (not this phone), seems I get one for cheap with a broken display, I fix it and someone offers me more than triple what I paid for, so I keep selling them :-/ (a man cant turn down a big profit). So I know how to pull this phone apart and replace parts if needed. I was looking to give Android a solid shot here (I am a Windows Phone person now)and not sell this one...
Not sure if the display is toast or this is just a Bricked or something else.
Note:
-If I connect to a PC, it connects fine
-When the phone is on, If I touch the lower of the screen, I hear clicking
-Double click on the center of the screen wakes up the display.
-Verzion software tool does not detect the phone (even though a drive is mapped for it)
Also to know, I have never rooted a Android device, so no idea on how to tell if it's rooted or not from the file system. Yea, when it comes to Android devices, I am a NooB.
Any idea ?
Thanks in advance !
Ok, Still trying to trouble shoot this, figuring it was a Brick or something with a lot of effort (The touch screen seems to work but, power off was a guessing game where to push to get it into bootloader mode).
I tried to go back to Stock with it, following these directions...
http://forum.xda-developers.com/showthread.php?t=2448960
Now during the process, every once an a while, on the top of the screen, I can see about 1/2 of the ICONs, it's static so it does not update but, it's the most I have seen off this display.
After showing Successful, it's still doing the same thing. accept a hair of it, static across the top of the screen.
So, does this lead down to a hardware based issue (if so, what part should be replaced), or is this display damaged and needs a replacement ?
Has anyone gone through this and can help ?
Edit, Picked up the one of the cables for the phone that the video, power, headphones all plug into, as all my problems are resulting in something that plugs into this cable, figured I would give it a shot, The only things that are left are the Main board, or the display itself.
Maybe this will fix it ?

Top White "Flat-tire" glitch after update (forced one)..

Hi you all!
Has the title says, sometimes a white glitch in the top appears, normally after a charge overnight just after I disconnect the device from charging. The problem in my urbane appeared after a forced update by adb sideload, don't know if it's due to that but I'm not sure until I hear other persons that made the same thing, adb sideload of course.
Anyway I'll probably gonna take it to warranty, cause I'm afraid it might be an hardware issue... :crying:
When I have some kind of an answer I'll give the feedback.
Already posted something similar in other thread ( " I've already done everything to the watch, unlocked bootloader, installed TWRP and also pushed by adb sideload the new version of Android wear, the bass version one (LCA44B) and all went fine.
Although I will going to take the Smartwatch to warranty, cause lately, not always, he's been doing a strange thing... After fully charged, the screen in top center, starts to blink (of White color), kind of a flat-tire inverted really strong like a flash! Obviously it's a glitch of some kind that affects the screen... Even with a reboot, he keeps doing it while booting... Lucky of me... Damned...")
The unique solution I've found was to switch of the device, not reboot, I must switch of the device or else it keeps doing it...
It only happened two times... But... Its f****d...
Edit. Posting some pics in a while...
Sorry by taking too long but here are the photos and video....
Still had the time to take it to the store were I bought it due to work shifts and free time to do so...

Yes, mine was very intermittent. It first happened after landing on a long flight... figured it was an air-pressure thing... it went away.
It was then intermittent / infrequent over the next month but last week it suddenly got a lot worse, and more frequent (i.e. all the time).
New video:
Contacted Amazon, and had a replacement delivered yesterday - so I've swapped it out for a new one - so far so good

Moto X Display [un]Dead?

So a couple of days back I was updating my apps from Play Store over WiFi and after that I tried to check the Amazon Appstore app for updates. Everything went normally but after the completion of the update check process my screen started displaying artifacts, somewhat like this as it happened to a Moto X 2014 user, mine is a 2013
http://forum.xda-developers.com/showpost.php?p=59982007&postcount=12
then after a while the whole screen turned to this;
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The touchscreen was working though so I was able to turn the device off by tapping in the center of the screen at the position the 'Power off' prompt usually appears but on restart the same damn thing. This pixellated artifact display was even showing in the boot up screen and then the screen stayed on until the power button was tapped to turn it off. I even checked the power off charging screen and it was the same, so I left the device off for the night, planning to take it to a service center the next day.
The next day when I turned the device on it was the same pixellated screen so I proceeded to do a remote wipe from Android Device Manager portal since the device already had Wifi on but then suddenly the display came back, just like that. I was unable to recreate the issue by following the same steps as it happened the first time. I have only like a month remaining in my warranty period and with my luck it will surely resurface after the warranty is over.
So my question is, is there any way to find out if this is a hardware or a software issue? Someone on that other thread I linked said something about a qcom bug in the adreno drivers,
http://forum.xda-developers.com/showpost.php?p=59986742&postcount=15
so could this be a result of that bug? My Moto X (2013) is on stock 5.1 and is running quite smoothly after a couple FDRs. If this is in fact a software bug, would it persist after a shutdown/reset? A question of overheating can also be ruled out since the device was left switched off overnight and there was no change in the display after turning it on the following morning. Then how did the display restore itself after the device was left on for some time? Was it an internal process involving the graphics subsystems that somehow crashed the adreno driver and was reset after completion? I also made a post on the official Motorola forums but unfortunately nothing helpful there either. https://forums.motorola.com/posts/f371030235
This whole thing is really spooky so if anyone is able to throw any light into this, it would be greatly appreciated. Thanks in advance.

Pixel 4XL Screen Failure

Hi, the screen on my Google Pixel 4XL just went bonkers with all this flickering purple lines. Sometimes, a portion of the screen would still display normally. The phone has just reached 2 years of usage and I have never dropped it before.
The touch screen is still working normally as I have tried using the phone while mirroring to my PC. The 90 Hz refresh rate has also been turned off.
May I know what is causing the problem and if repairing it means the replacement of the entire LCD screen (it will cost me about 250 USD in my country)? I am trying to decide if it is worth repairing the phone or to just go for a Pixel 6 or 6a.

Hey!
So that doesn't seem to be a software issue but you could try to factory reset the phone. If it doesn't fix try to open the phone, disconnect and reconnect the display cable. If nothing worked the screen is damaged. Here's a link to the ifixit guide. Things that cann cause screen to break are extreme temperatures(if you left the phone under sun for long periods of time or where you live snows and you left the phone outside), water damage, or even hard strokes.
On Europe you can find replacement screens for 70 euros more or less so it's up to you if you want to upgrade or not. I personally really like the P4 and I personally would fix it BUT it's your decision.
Hope this helps you!
