Touchscreen problem? - Google Pixel 4a Questions & Answers

I've come across an annoying problem with my new pixel 4a.
When within an app and I tap on something near the top of the screen, the screen switches to the view where all open apps are shown to choose from. (Like when tapping the little square at the bottom right)'
Is this a touchscreen bug, a gesture I need to turn off, or something I'm doing wrong?

It sounds like either there is a problem with the touch-screen (try rebooting the phone), or maybe you installed some app that has "added" that "feature" (so try uninstalling any "utility" app that might be adding that ability.

Thank you for the quick reply. It's a new phone and I'm still exploring it and android 11 before rooting it.
I rebooted and so far seems ok. Time will tell.

Spoke too soon. It just happened again one time after reboiting and I could not reproduce it again.
I was in Firefox and tapped the top right corner and the 'overview' screen appeared. I then tried to reproduce it repeatedly but it would not.
It's a brand new phone and I've not installed more than a couple of apps on it. I'm new to android 11 and didn't know if it was a new 'feature' I was unaware of. Will watch some more.

I would return the phone and get a new one.

I think I will.
Thanks.

[Q] Slow Home Behavior

Hello everyone!
Let me start off by saying that i'm actually using an unrooted, officially update nexus 5, updated to the latest 5.0.1
I have no problem whatsoever, battery really seem to have improved, but lately i've been getting a strange behavior
After a period of use (it goes from a couple of days to a whole week) the phone oddly slows down when i press the middle button, to return back to the homescreen.
For example, if I'm using the facebook app, and watch a couple of videos along with opening a few external links, when i press the home button, the whole home "loads" from start. I mean, i literally see nothing for a second, then it slowly loads widgets and icons. After it's been loaded, everything works flawlessly again, but if i open facebook again, use it for a while and press the home screen, it loads again.
Mind that i have no custom drawer (i tried Themer, it gives me the same error, it says "loading homescreen" when the problem appears) but the problem is still there with the stock homescreen. I tried force-closing the apps i used, thinking about a memory issue, but to no avail. I have to turn off and turn on the device, and everything works wonders again.
Is there any app that could help me with this issue? I'd like to understand why it's doing this and which app is slowing down my phone.

I am not Sure whether this is 100% sure, But have heard that there is a memory leak issue in lollipop. Which might be the reason of ur problem. And the oly way get enough memory is to restart. But again, I am not Sure whether the above information is correct though.

I've heard that too, but it's strange that it has appeared only now. I haven't had this kind of issue ever since i updated it.
The FB app is just real buggy. My personal theory is whatever that app does exposes the Lollipop memory leak.

Yep i know about that, the FB app is just horrible script-wise. Nevertheless, i've never had THIS problem. And even if i forceclose it, it doesn't solve the problem anyway.

Bizarre black box lorem ipsum bug

Has anybody ever seen anything like this? I'm experiencing a black box popping up maybe 20 seconds or so after booting that is unclosable with lorem ipsum text in it, here are some screenshots:
[xda won't let me post links yet so bear with me and fill in the rest of these urls]
imgur /LYCMosA.png
imgur /fsh6nWh.png
imgur.com /tde44HA.jpg
The box cannot be closed, and anything above it doesn't respond to touch input, but everything below it can still be used (like the shortcuts to chrome, contacts, etc. in the last screenshot). This box persists everywhere, including the lock screen.
Additionally, when I go to the lock screen the screen starts turning on and off rapidly, forcing me to reboot by holding the power and volume down key into maintenance mode.
I am able to start the phone in safe mode with no problems (safe mode disables all apps that aren't samsung or google), making me believe it's a third party app that is causing the issue and not something in android. But before I begin the awful task of uninstalling apps one by one to see which is the one that's causing the issue I figured I'd turn to reddit for help.
Additional info: I'm on verizon, the phone is rooted and I'm on 5.0.2
Flash with stock 5.1.1 ROM via odin.
Update: If you're reading this from the future it was cerberus, the security app. Really ****ing pissed because I uninstalled just about everything else because I didn't want to uninstall my security app until I had my phone back at my house (just tempting fate too much). Oh well, at least I've figured it out.

Warning to Kingo Battery app users!

Last few days I had Kingo SuperBattery app installed on my android tablet and last time I turned it on the touchscreen was VERY messed up. I had a Messenger chat-head and some other notifications but the device was very very slow and I couldn't click/touch anything properly and it looked like I had one of those viruses you get on the PC that make it slow as sh** no matter the hardware you have. It looked like somebody else was using my device and all the widgets and icons in my home-screen were trying to move themselves and other weird stuff like that. The first thing I did was to turn-off the wi-fi and it was quite difficult and it didn't even work. I tried using the Clean Master Antivirus app and start a scan and it did not find anything but I also did a phone boost with it. I didn't see any problems with the the device while in the CM Antivirus app, it was kinda like a way of taking a deep breath and then again the same stuff in the home-screen. I couldn't click/touch on the chat-head from messenger and something was always trying to open my notifications slide. The reason I used my tablet was actually because I was trying to fix my phone using my PC (bootloop issue) and the only way to get the .ftf (ROM file) in the sd-card was to use another device (I couldn't find an sd-adaptor) so I tried using my tablet :/ but then here is the "new" problem I'm telling you about ^^^^^^^^^^. I prayed to God at some point and things started getting easier :angel:. I managed to go to developer options and enable "Show Touches" and that's when I saw there was always a dot right above the notifications area (for those who don't know, the Show Touches setting shows a dot on every spot where there is touch). I opened the CM app again and found that the persistent touch-dot (if that is its name) disappeared. I kind of found some tricks to use the touchscreen properly after I realised how the problem works. And then I uninstalled the Kingo Battery Saving app and the problem was gone! :laugh:
Moral lesson: be careful with third-party, rooting, and suspicious looking apps.

Strange moto G3 touchscreen response problem

Hi all, I did a search with no luck, so hopefully this is a valid question!
I have a weird problem with my moto G3 2015 and was hoping you guys wouldn't mind reading about and possibly offering some kind of advice if it's not too much trouble.
Every so often, I'd say at least once a day, the screen becomes unusable until I press the power button a couple of times (to turn the screen off and on again). Even when I do this quick fix, the problem comes back very shortly afterwards. It only goes away after 10 minutes or so, or if I get annoyed and put my phone away. I thought this was a hardware issue but don't believe that now due to the following:
1. It is a different problem depending on the app I am using. In facebook, scrolling is no longer smooth, and doesn't continue scrolling if I flick down the feed. It only scrolls down while my finger is actually on the screen. I am also unable to actually 'click' on anything, only scroll. In Brave (my browser) it acts as if I've just double tapped the screen, as in if I move my finger down it zooms in, and if up then it zooms out. In snapchat when watching a friend's story it acts as if I've held down on the screen in order to forward their snap to somebody else, and then it doesn't respond at all to any touch.
2. The 3 buttons at the bottom are always functional no matter what
3. If the problem begins when I'm in an app, if I go to my home screen, I am able to navigate my home screen and app drawer with no problems. It's as if the problem is contained within the apps.
This started a few months ago while I was running the copy of android that the phone came with. I put on lineage OS (lineage-14.1-20170629-nightly-osprey-signed) and pico gapps (open_gapps-arm-7.1-pico-20170629). This seemed to fix the problem for a while but then it started again a week or so in.
The fact that the problem is only happening while I am in the apps, and disappears when I exit out of them makes me think it can't be a hardware issue? I am also no expert with phones or android, but am somewhat experienced in rooting and playing with settings etc. (I'm not sure if it happens in other apps I'm afraid, I can test if need be next time it happens).
Thanks so much for any help, and please let me know if there is any more info I can give you!
P.s. The new ROM is much better than the old one.! The battery definitely drains faster though, but that's a whole other problem

That is actually typical behavior on older devices using as many social media apps as you're using. Especially Facebook and Messenger if you're also using it.
Have you tried booting to recovery and wiping cache when this happens?

Thanks for replying!
When I flashed lineage OS I believe I wiped the cache. I will do it again though to see if it helps.

Yeah, you wipe cache when you flashed, or at least you should have.

Hi there
If the issue was software related, a change of rom should have solved it.
If the issue is kernel related, all users must face the same issue...but that is still not the case.
So This might be an issue with the screen being old. When the power consumption fluctuates, lcd screens can misbehave.

Samsung Interface Not Updating

All,
First time poster, frequent visitor of XDA Forums. I've come across an odd issue that I don't know how to solve and I'm hoping some of you smarter than me folks can get me squared away.
I have a Galaxy S8+ from AT&T running Android 7.0 and Samsung Experience 8.1.
Problem:
I've recently noticed a delay or completely non-updating interface on my phone. It updates on occasion, but I can't determine what triggers an update. For example, I will pick up my phone from the desk and when I press the power button it shows the accurate time. When I unlock the device, the sense flip clock I use on the main home screen shows an earlier time (could be 30 minutes... could be a few hours). I don't believe it's just the Sense app because I noticed this issue where I checked a facebook messenger app that came and and when I closed the app, it still showed I had 1 notification. I went back in thinking I had another new message, but I didn't. So it was still hanging on to the notification. It happened a couple times with a text message as well. Most importantly, my calendar doesn't alert me prior to an appointment either, even though it's showing in my calendar and an alert is active. If I save an event, and exit, I can normally see the event appear on the on widget immediately as well... but that hasn't been happening. I have to press the widget to open it and confirm it is there (which it always is). Eventually it refreshes and shows up. But that delay is likely the reason why I'm not getting my alerts.
All of this did seem to happen after a recent update Samsung/AT&T pushed out but I don't know for sure. I tried clearing the cache from the boot menu but it doesn't seem there is wide success with that.
And perhaps I'm just not a good enough user, but everything isn't all backed up in the cloud so doing the factory reset to me is always a fairly large task as I have many things to manually transfer out and then back in. Not sure if there are great tools that help with this on a stock phone.
Samsung smart switch works wonders, the only thing that doesn't restore is passwords, you have to have and external SD card for it to work, or plug it in to a computer

Go to settings and check if your time is setup to adjust automatically.

That is not the issue. As mentioned, it's not just the clock it's multiple interfaces.

High level overview of issues...
I have the Ring Doorbell app. I get notifications after "live". Could be 5 minutes, could be 1 hour... or possibly not at all. I have the app setup on my wife's iPhone and she gets them immediately. If I restart the phone, I will get notified right away (it's like it runs the app again and then I get the notification). Keep in mind, this is AFTER i disabled the battery optimization feature for the Ring app.
I also notice it occasionally with texting. I won't have any text notification in the notification panel, nor will my messaging icon have a little red circle indicating a message is there. But if I open the app, a specification conversation will have a red circle indicating a new text is unread.
All of this is leading me to believe the Samsung UI itself is not updating and therefore notifications that actually have arrived (from whatever app), are not displaying because of the UI and not because of their own delay.
Because of this concern I have turned off battery optimization for "System UI", "Themes", and "TouchWiz Home". I have not seen any change however.
[Solved]
I was able to determine by various other threads around the web (thought for sure I'd find it here, but I didn't) that the culprit might be the Google app. Supposedly it was fixed in some prior release, but it's not on my Galaxy S8+ w/ AT&T.
Once I disabled the Google app all the odd issues with notifications and clock interfaces and app icons not updating went away. The downside to disabling it is that I lose the Google Assistant functionality which stinks but otherwise there is no impact to using the phone. I re-enabled it at a later date and it worked fine for a few days and then started acting up again. Once I disabled it, the problems all disappeared. Clearly Google app is to blame.
