Android 11.0 Pixel 4a Touch Sensitivity Issue (inaccurate touches) - Google Pixel 4a Guides, News, & Discussion

Ever since upgrading to Android 11.0, immediate issue has been the sensitivity of the touch screen.
Scrolling up and down will randomly select a link or an item on the page i was scrolling. This seems really evident when you open Google when you scroll all the way to the left. Start scrolling up and down and see if you get errant presses. Seems to be happening a lot on the right hand side of the display where the touches get inaccurate.
I'll be really frank here.... Google sucks at testing and pushing stable updates...

I am still on the 11 beta. When I switched from android 10 to 11 beta I had this issue. Taking off my screen protector solved this issue although I don't want it to be a permanent solution

Got my 11 update this afternoon and have been playing with the phone since. Updated all apps that were available to update, then shut down the phone and restarted. Haven't noticed what you are talking about at all. Just went into Google, as you mentioned, and haven't seen any issues. Will keep an eye on it; but my first thought is if there is an installed app causing issues....

I tried the beta last week and this happened to me. I have to go back to 10 and reinstall everything. I might wait a week or so for others to respond before I trust 11 again.

I found out that they made changes to pixel 4 related to touch sensitivity (making it more aggressive). Wondering if that is what's affecting it.

Just upgraded my 4a to 11 today and I'm having the same issue. Also noticed it on the launcher...long press on an app to drag it just immediately opens the app. Just trying to type this post is a struggle. Touch sensitivity and accuracy is all messed up.

Clearly Google has an issue on their hands. Guess will need to escalate this to tech journalists so that they do something about it

Not having this issue. On A10 I felt touch and especially navigation swipes were a tad insensitive relative to other devices. On several occasions I contemplated regressing to 3-button navigation (ugh). A11 fixed that making navigation feel natural again. No problem with taps - yet.
Right/left swipe sensitivity can be controlled in settings on A11. Left mine at default.
Stock 4a w/Nova Prime. Spigen armor case (slightly raised edges). No screen protector.

This issue is getting reported a bunch on www.reddit.com/r/Pixel4a. I personally had the issue pop up a few weeks ago after I installed 11 beta 3. Downgrading back to 10 fixed it.
Some people have said the issue goes away if you remove your screen protector but obviously that isn't the real solution if your phone was working fine prior to the update.

I just posted this question lol i wish i seen your post before. Im dealing w same issue, kind of feel better at least knowing im not the only one dealing with it lol

I think all the touch problems are related to Google Assistant, this app is just too busy messing things up. I use Nova, turned the Assistant off but it was still showing up with a prompt/notification on the bottom telling me to turn it on. So I have disabled the entire Google app and I don't see the Assistant anymore, all is good. Google Play, Pay, Maps etc..., the things I need they all stay intact. And btw, I don't use screen protector.

The only issue I've found is that they seemed to have changed the swipe logic on the homescreen launcher, it acts like it's looking for a slightly different gesture. My muscle memory for quickly accessing overview had to be tweaked slightly, but I've gotten used to it.
I'm not noticing other issues with screen sensitivity. I have an OtterBox Commuter case and the "OMOTON" glass screen protector on my 4a. I adjusted the back swipe sensitivity because the lip of my case is fairly large but that's it.
I'm sorry to hear there have been issues with this

I'm assuming you're using a screen protector?
Try the new touch sensitivity toggle

It helped my touch issues to lower back sensitivity. Using LK brand tempered glass

This issue has been fixed. I think what's troubling is that it was fixed without needing an update... So what dynamic changes are being made within the OS without the need for an OTA update?
edit: nvm its back again. anyone else having touch issues again?

Can confirm. I'm having touch issues every now & then after update to 11.

Reddit has a thread with over 73 responses confirming the issue as well. Still waiting on Google for a fix.

I have same problem and it's so annoying, I also have a screen burn in almost 1cm by 1cmnafter one day of use and volume going up and down on it's own ???

Still no issues here. I am not downplaying those that have this (not at all!) but wonder if an app conflict is part of the cocktail. I do not use Google Assistant which some have implicated. Also have very few apps authorized for screen reading (albeit probably not a factor)
Edit: read on; screen protectors and heat appear to be contributing factors.

Sad to report this issue is NOT yet fixed. It appears to only happen when the phone heats up WITH a screen protector. Just played a game of Risk for about an hour and the problem came back. Just removed my Supershieldz screen protector and the problem is gone. When the phone cools down I'll add the screen protector back and the issue most likely won't come back until the phone heats up again. This never happened on Android 10, so something must have changed with the update. Hopefully it's just a simple software fix and not a hardware issue.

Touch Sensitivity

Hey is anyone elses GTab's touch sensitivity kind of off?
I noticed, compared to the iPad and Galaxy Tab, some times it takes me 2-4x of tryinng to press something to get it going.
Its almost like the screen cant pick it up sometimes. And sometimes when scrolling, it selects things, when im just Trying to scroll..
Also the top left HOME button on screen is always iffy, most times ill need 2-4 more times 2 press it to get it going.
I am using TNT 2.2.
Anyone else noticed this? i feel like its hardware.
Definetely not as responsive as my EVO. Maybe its the cheap screen. I wish it could be fixed via software, but fat chance. I guess not all capacitive screens are created equal.

You nailed it. IMO Samsung has been making the best color screens for years.
Have had absolutely no problems with touchpad responsiveness from my gTab... Just as sensitive and responsive as my Dinc.
Really does seem like this hardware is hit or miss... Some tabs have no issues some have many.
You guys are just plain spoiled. I've gone through Palm IIIx to now the gTablet, and it just simply has the most responsive touch screen that I've ever used, but I've had recent experience with the dreadful Augen GT and the slightly less dreadful White Pandigital Novel, both of which had worse touch screens than other devices that I've used.
One thing that I do, do for the gTab though is to clean the screen quite a bit. At a minimum I do so before every use as I find the fingerprint/body oils buildup to be annoying in fairly short order and it might have some impact on touch responsiveness. It's the worst fingerprint magnet that I've ever seen actually...
No issues here with single touch sensitivity, pretty good on that. Just as good as my Nexus One. Multitouch and pinch-to-zoom still a bit flaky. I am hopeful that will be resolved by software and/or driver improvements, as it was on the Nexus One.
The only issues I have are when the screen is too dirty or too clean. When I really scrub and clean the glass off entirely, at first it's a bit too "sticky" almost when my finger contacts it - maybe that's because it's winter here in the Northeast and my skin is dry. Once I've used it a bit and it gets some finger grease on it, it works perfectly. But if it gets grit or solid dirt on it, that can definitely interfere with the touch screen too, as with any capacitive screen.
I suspect the optimal thing would be a really good screen protector that's easy to clean and has that smooth finger contact feeling out of the box, like the iPad's glass does, for example, which I think has something to do with the oleophobic coating.
Typing this on my gtablet. The issue for me is the keyboard. There are parts of the screen that are unresoonsive making some letters not get tapped. The A key and l keys in particular. As a result I can't type smoothly or naturally because I will make several errors along the way. This does not happen onky iphone or my wires ipad.
it might bemy rrleason for sending it back as it takes too ongoing totyr correctly and I get tire d of all the corrections.
Well if your using the stock tnt keyboard, it sucks. We can learn from the ipad, with the size of the screen it has huge keys that cover a lot more of the screen then our stock tnt keyboard. I use smart keyboard pro with the key heights set to maximum and it works so much better, like 100x better. Even has voice to text.
Can people check their keyboard? I find that if I type most of the keys they type fine. However, the letter a key seems to only work when pressed offcenter which prevents. From typing properly as I must deliberately slow down and make sure it is correctly typed otherwise I get many errors. Could this be a defect in my screen?
Or is this a ui problem with tnt?
This could be a deal breaker as I misspelled every word if. Has h letter A
Letter A
I have the same problem with the letter A, and sometimes P. Otherwise touch is great
Figured why this tablet is driving me nuts. There are two dead zones on this tablet. Someone please do this test so I can figure out if this is just my tablet or all g tablets.
Download mulitouch vis test. Do rapid light touches in the area where the 'a' key is and delete key are. If I do this test in the middle of the screen it registers every single tap. But in those two areas I can sometimes tap 10 times in a row and not have a single tap register.
If this all g tablets then I think it's going back.
Also is there a keyboard with arrow keys? Trying to place the cursor can be a real pain.
Agreed bout the dead spots. The stock tap n tap western keyboard seems tominimize them due to the angles but if I try another keyboard I miss the a and the return button all the time

Downloaded the app as well because I, too, am having the same screen non-responsiveness issue. Lo and behold the area where the "L" key is is a pretty dead spot. It would register about 40% of the quick taps I did in that area. Is this is a software issue? If so, I can live with it and hope our wonderful devs release a software build that resolves this otherwise, this thing may be going back because it's driving me up the wall!
I do see the occasional missed tap here and there, but no consistent dead areas that I've noticed (the A and L buttons on keyboard seem fine to me).
Multitouch sensitivity is wayyyyy mis-calibrated though - you have to use very heavy finger presses to get multitouch to register. This is some sort of driver or calibration issue that should be easily solved.
I found a binary called TSCalibration in the /system/bin directory on my VEGAn ROM G Tablet. Tried running it from terminal, but it seems to be looking for a calibration.ini file on the SDCard. I'd be willing to bet we could figure out how to fix some of the touchscreen issues with some work, because I suspect they are principally software related.
If your issues with the touchscreen are anything like this...exchange it...
My new one requires very little effort if any at all to get the screen to respond...
However, if you're talking about the once in a while miss of a touch...yes, I agree with cutterjohn....you're spoiled. Return the device asap, so I could pick it up from an outlet...please?

There is a big difference between these dead spots and the occasional miss. I have no problem with the occasional miss. I just have to adjust to how my finger touches the tablet to get more consistent hits.
There are areas of my tablet that consistently do not behave like the other areas. Does that sound normal to you? I can't have a tablet where anything in the 2 corners is extremely inconsistent. If I have the tablet oriented a certain way the soft-buttons get put into one of the bad corners and that is really frustrating.
I don't think it is how I am holding it because the problem follows the physical corners and it is not relative to my hand. So that rules that out. And I washed my hands and gave the tablet a good cleaning so dirt/grease/grime is not an issue either. It could have been too clean but why only two corners?
I have many weeks to go on my 30 days so I will keep screwing with it to see if I can come up with anything that is a workaround or explains why it is happening. It is insanely fast and it's modding future looks extremely bright with such talented people. If I get fed up enough, I'll exchange it and hopefully get one with a even touch response for the whole screen or simply return it and wait a couple more months for Honeycomb tablets.

Whoa. That video was pretty bad. While mine is not like that (thank God), I just tried hitting the app drawer key and it only registered after the 13th tap?!?! seriously wtf. While it isn't a "dead zone" per se, that's still pretty bad. There has to be a software fix to recify this issue with the right side of the screen. (my "L" and "delete" button are pretty bad as well).
THAT is a defective product...
I'll do another video to compare with my new one...WITH funky assed salty sweat all over the screen. Works flawlessly...
Is your model that is working well running stock firmware and keyboard?
mine is tent lite and the stock keyboard is ok. It if I try to use the alternative keyboards then I get consistent misses on key presses especially on the letter a.
I'm always tapping *constantly*, like 10-20 times on certain spots around the corners and edges of the screen, I'm about to return mine because of this.. Believe I'm still in the 2 weeks with office depot, will have to go snag the $350 one over at sears and hopefully it will come with a screen protector this time (this one I have didn't come with one, wonder if that has to do with the dead spots)..

What is the fix for poor touch screen response on the Triumph?

Hello,
I am convinced that something is wrong with the Triumph. I searched for "keyboard" and "response" in the thread titles but got nothing.
Basically, the screen doesn't register my touches consistently. Is this something that is fixable by a software update, or is it faulty hardware? It's almost like I type too fast for the Triumph. But when touching a link, it often doesn't register, either, and it's not localized to any particular area of the screen. Slowing down my typing seems to help, but this is making the phone in my opinion, unusable. I have no reason to believe that I got a faulty unit.
What is the fix for this problem, and sorry if I missed the answers somewhere in the forums.

No, I have not, but I have thought about it. I've heard conflicting reports about whether that helps or not. In the past, I have not noted these screen protectors to be causing the problem. Can anyone speak with authority about whether removing the screen protector solves the response issues? It's a one-way procedure, because there's no way that I'll be able to get that screen protector applied as perfectly as it was at the factory.
Thanks

I can't speak with authority, but I can speak based on personal experience. It made a HUGE difference for me. And no, I haven't had any scratches on the screen nor have I had any problems since I removed it.
I can't say but I have notices that when my available RAM falls below 50 mb that the touch becomes less responsive, that and cold fingers.

The touch screen does lag, regardless of the screen protector. Its most apparent to me when opening the app drawer; it's hard to get the screen to roll. I think it's a combination of literally cold fingers as well as a sort of metaphorical coldness of the device itself; it seems that the lag effect diminishes as the device settles into its groove after prolonged use. I notice the lag when the ROM is 'fresh.'
I am on my 2nd T and they both exhibit the quirk. LPP and the new ADW seem to help her work it out. Perplexing little devices on an intentionally-attenuated redheaded step-network, fer sure, but virtually unbrickable, and oh my black jesus do i ever love me my $25/month, contract-free ultimateness.
I've spent a lot of time trying to resolve this issue in the TG-Reloaded CM7 ROM. Updating & rewriting the bi041p touchscreen driver in the kernel. I'm finally ready to just say it's a hardware problem, maybe a grounding issue. The interrupt sometimes just doesn't trigger reliably.
Well they're are two things you can do it increase the touch screen sensitivity,the first way would be to flash ROM or a kernel that has reworked drivers that are supposed to help touchscreen sensitivity a little.The next thing you could do that I think would greatly improve touchscreen sensitivity would be to take of the factory installed screen protector as it is very thick and low quality.

Thanks God I Finally get a No Problem Tf700!

I returned a TF700 and replace a order again on Amazon
I just got my TF700 and the first things I do is press the screen down to see if there is a clicking sound or loosen screen problem.
Thank god it doesn't have such problems
Then I turn it on and check for light bleeding. Well, there is a light bleeding spot on the left corner, but not obvious and won't be notice under normal use.
The rest of the TF700 are fine.
Now I am waiting for the case and screen flim.
I am not going to use it until the case arrive, last time I drop it from around 5~8cm height and the corner just blend and the screen pop out. I cannot believe how weak the structure is (Absolutely much weaker than the ipad!)
Hope the case could give some protection.
Waiting for JB now

Yes, +1 on the case. It's really important to have some protective covering for this device. It's so beautiful and it would be such a shame to scratch and mar it up.
Without issues, Asus's tablets are the best:good:
Sound funny but it's true.
Do you have Bluetooth earphones to test it out with? I am happy with my tablet except for the Bluetooth audio lag.
What about lags and performance ?
Mine is perfect built with no hard ware issues, but I feel there are some software issues. I want to know is it common issues or only mine.
Some lags in main screen when first time going through them it looks like it needs time to load the pages and when downloading/updating apps from the market there are some freezes in screen and sometime while browsing using chrome the device become unresponsive and the screen freeze and I have to shut it down...
The device is great, but I'm wondering about the software issues and smoothness of this CPU

same here but i think it's more noticeable because i have a nexus which is very smooth. hoping jb solves all the lagginess.
I just received my TF700T 64GB from Amazon yesterday and no issues with the screen clicking, actually it is very solid. It does have some light bleed out on the start up screen. But any other time it is not noticeable at all. As for the BT issue, that I am not sure of since I don't have a BT headset.
I did have a Freeze and Crash with loading Glowball. Once I turned it off and back on, it didn't seem to have any issues. The lags, in loading pages I have noticed this every once in awhile, which is strange. Wasn't sure if it was my Wifi network. However I have not had any lagging to the point that it locked up the page where I would need to shut down and reboot.
As for a case, that is not for me. You purchase a device like this due to performance and how thin it is. By putting a case over it, then it is thicker like some of the competition. Besides when dust particles get behind the case it will scratch the aluminum anyway if not careful. Not quite sure how one drops such a heavy device. If you have Accidental Damage insurance on it, no need to worry. File a claim and get a new one, issue fixed.
Traded my prime in at my local BestBuy for an Infinity. Clicking around the screen and the buttons were mushy. Second Infinity the buttons were still mushy and there was a poor mesh between the aluminum back and the plastic strip. THIRD Infinity SEEMS ok (cross your fingers) buttons click good, not really mushy, no clicking around the screen, all seems well!
The clicking could be because the glue they use stays tacky for a bit. I would assume that after a month or so it should cure and stop being tacky thus the clicking. Just an idea tho...
It's actually a shame that there are threads devoted to receiving a flawless prime. Not knocking the OP or anything, but it's crazy how we shell out 1/2 a G for a tablet and "hope" that it's a good one... I got fed up with the stutters, lock ups, questionable-hardware-so-lets-blame-it-on-the-software concerns... I had a tf201 and was lucky enough to be able to return it directly to Asus and get a full refund, then I turned around and got the tf700... Went through two of them. First one had mushy buttons and a clicky screen... It was a c7... Then got a replacement which was a c6. Turned out to be a better build than the c7, but the GPS didn't work independently like it should have. Then, I checked the c7 and that didn't work the way it should have either. Both needed google location services active for GPS to work! Between that and reading about the tf300 issues with JB and experiencing the sluggish response times, non responsive touch screen, icon-less home screens, app force closes, decreasing wifi reception and just about every problem under the sun (ala prime), I finally decided to return it to amazon for a refund. It seems like the infinity starts to get really slow as you use it more and more... It has potential, but I don't have the time or bank roll to wait and gamble...
I'm sure there are people who have perfectly working infinity's but I wasn't trying to hold my breath any longer just to hope that JB would correct all the issues... I'm actually eyeing the iPad, but will probably wait until October to see what apple has up its sleeve... I don't care for apple, but truthfully speaking... Their products have a LOT less issues and the developer devotion to some solid apps only available on the iPad have me steered in that direction. I mean, I can't get scrabble for the infinity or the prime (when i had it)... Really?!?!
Well, good luck to the infinity owners, I'll still follow the forums just to see how things turn out, but I think I'm done with Asus... It's really a shame, because they have so much potential...

A510/A700 Senstivity Test

Hi guys.
Before buying my A510, I used to have a SGT 10.1. I sold off my SGT 10.1 2 weeks before getting my A510, so I was never able to do side-by-side comparison between the two.
However, judging by the response in the forums at that time and by my personal usage, it was clear that the Acer tablet had some serious sensitivity issues. I couldn't confirm how bad, but it was bad enough to be noticeable by me based against my SGT 10.1.
To me, the worst thing is when putting the tablet on a hard flat surface, like a table. This is where the sensitivity, for some weird r!eason, takes a very BAD hit. I just got a Note 10.1 yesteray, and used both side by side. The Note could flawlessly take input when laid flat on a table. But not the A510.
Any idea why? Do try if your tab takes a hit when placed on a flat surface and let me know.
Thanks
I had an A510 that I returned for just that reason; sensitivity not only took a hit, it became almost useless when laid on a table. Problem was compounded by a screen protector. A700 seems much better. However the most recent update (1.029 -> 1.057) actually made things worse as far as the touch screen. For a while I flashed back to 1.029. Then I decided to update to 1.057 and root, and now I am using Acer Liquid Settings program which requires root & seems to help sensitivity. I am typing this flat on a table with only 1 or 2 missed touches for this reply, all in the 1st sentence.
Edit: There is a YouTube video that illustrates this problem in the A510 Search A510 problem on YouTube.

Indeed, I have EXACTLY the same problem as that in the video. The actionbar is TOTALLY unusable on a table. When I lift and use it in my hands, things are much better but still very much worse compared to other tablets.
Now, the thing is, from what I read, an update from Acer caused this issue. Can anybody vouch for that?
I got my tablet in mid-June, and by then it was running on the latest version. I've not gotten any new updates to fix this issue. Assuming it is a software problem, why hasn't Acer issued a hotfix? Also, this must mean ALL A510s are affected right?
screen protector?
ok, may sound a bit weird, but i experienced exactly the same "issue" on my a700. if i use the tab in bed or in the stand i got no touchscreen response. but this inresponsiveness has startet sometimes after mounting a screen protector at the tab. it just takes a while, until i recognised this behavior. travelling around the last weeks and was trying to navigate through the music library at the hotel brought the problem up first time.
since i removed the protector foil, the touchscreen response is back in all situations.
regards
There have been past threads on different devices that point to a grounding issue when this occurs. Your body is a conductor when holding the tablet so it works better. If the device is grounded properly then there isn't an issue either way. If your saying this was the result of an update then that's better then a hardware issue since it can be fixed much easier, once the company is made aware of the issue of course.
Don't hold your breath...

Yes a software issue can be fixed more easily...
IF the company decides to acknowledge the problem, act on the information and then go to the (likely considerable) expense of creating and releasing an update to address the problem. There have been many reports of this touch screen issue in the A51x & A7xx Iconias throughout the Internet especially, but not exclusively, if one is using a screen protector. Amazingly Acer claimed to address this in most recent OTA update for A700 (1.057), which was stated to address touch screen issues; it only made them worse on my A700. Go figure.
So I have the A700 and do not find any difference in touch sensitivity between the tablet laying down on a table and it being in my hands. Are you guys finding a big difference between the two?
Unfortunately it doesn't mean its perfect as I do struggle with touch sensitivity with the edges of the screen sometimes, which can be annoying as a lot off apps/browsers tend to put buttons in the corners.
Quick fix is to toggle the screen sensitivity everytime you boot up. (Change to medium then back high again, you do this every boot.)
A more permanent solution (applicable to the A510 only), is to flash NoThrills' optimized A510 rom along with the included NoThrills Kernel. This has solved my screen sensitivity issues.

Oh my God, you're so damn right! One of the first things I did when I got my tablet was putting the sensitivity to high, and I have never changed it since. Now that you mention, I put it to medium, then immediately high. Using the tablet on a flat surface is possible...my taps get registered flawlessly.
So, this means it is not something wrong with the display panel itself, but a software issue. Here's to hoping that Acer will fix it. Really weird man.
PS: Is there a code that I could tweak in the buil_prop maybe? I don't want to be flashing ROMs at the moment.
I was also wondering whether screen sensitivity could be addressed in build.prop. Anyone know?

I currently do not know of any build.prop or init.d solution. (So I guess it's more complex than I thought it would be.)
As mentioned though, I don't have the sensitivity issues anymore since using NoThrill's Optimized A510 WW ROM (The kernel was the one that fixed it I think, since I flashed Acer's stock kernel and I got my sensitivity issues back.)
So you might wanna consider flashing a new rom, or, flashing a new kernel at least.

Ghost *Scrolling*?

There are numerous people reporting ghost touches, however I am not one of those people.
Instead, I'm dealing with ghost scrolling...
If I'm scrolling through Twitter for example, randomly, my device will scroll up or down insanely fast, and will scroll quite the distance as well.
I've tried the workaround of disabling NFC but the issue is still there.
Just curious if anyone else has this issue and knows of a fix? I was tolerating it for a while but now it's beginning to become a little too annoying...
I have this in youtube occasioanlly
I have this happening as well in multiple apps. Disabling NFC has not helped.

Probably most likely accidental edge touches with your palm grabbing the scroll bar on the curved edge? Don't have my 7 Pro yet but I get this every now and then on my Note9.
None here since my case positions my hand far enough away from unwanted touches. ?

Hmm, haven't thought of this actually. I will actively keep my palm away from the edge and see if the issue persists or not.
Thanks for the suggestion!

Update on this,
I made sure there were no accidental touches yet the super fast and abrupt scrolling issue is still there
Hopefully OnePlus can fix this in a future update.
I'm still dealing with this issue on 9.5.7
Still present on 9.5.8
Seems like other users are reporting the same but others are surprised hearing about it. Makes me think it's a hardware issue.
I get it on Google maps if i zoom in or out. The screen will pan way right after i take my fingers off the screen

I've seen this on multiple devices. It happens with some apps. Not exactly a device issue, I don't think.

O right. Never experienced it before on any device, including my previous OP phones
