Hi all,
I am on my third Pixel 2 (not XL), having returned two others for issues with touchscreen sensitivity. It behaved similarly to the issues being reported by the XL users, in which the touchscreen intermittently "misses" screen presses or simply does not register them. Enabling "Show taps" and "Pointer location" in Developer Options results in no visible press or location coordinates, at zero pressure, during the times it does not register.
The cause (at least for me): I disabled "Squeeze for your Assistant" under System > Gestures > Active Edge. I suspect that disabling it changes the whole screen's sensitivity map rather than simply the edges. I've reported it, but maybe this'll help someone else.
Thank this has worked but now I'm thinking to take it back. A phone I can't even use the features it comes with isn't worth it.
Thanks for this workaround! So I set the squeeze sensitivity to one below default and the screen is much more responsive already. Might be worth trying before turning it off completely.
Active edge is just a few pressure sensors on the bottom sides of the chassis. The Pixel 2 does not use the edges of the touchscreen to detect pressure. This is most likely placebo. Try a thinner screen protector with adhesive on the whole panel.
Check out the ifixit teardown for proof!

Definitely not a placebo.
I had disabled active edge last week and was pulling my hair out what caused the touch issues i suddenly had. Then i found this topic and enabled active edge again. Issue immediately resolved.
I suggest you try disabling it Bower95, you will likely notices skips and touches not registering afterwards.
Confined this workaround makes the corners of my screen much better not perfect but much better

Hi all,
It seems to me that the edge of the lcd screen is not responsive (both left and right) at times when I put it inside a leather case(similar to theM1 case). If I take it out of the case, it's very responsive.
Does anyone notice the same problem?
Thanks.
I've brought that up before. Out of the case the screen is very responsive all over. In a case it's much less responsive around the edges. If you use the screen calibration apk it helps a little, and I find you get a better response around the edges using your thumb than pointer.
I don't know of any real solution, or what causes it.

glad to know i am not the only one with the problem.
My guess is that the case must touch the tablet somewhere that confuses the touch sensor.
mine did this for a little while and then just went away. the calibration didn't help and reloading the ROM didn't either.

Can you try to remember what you could have done to make it go away? Changed or modified the case in anyway?
It's so annoying.
It seems as if the G-Tablet's touch sensor is EXTREMELY sensitive. It even detected my headphone wire touching it. I knew this because when I would touch it at the same time the wire was on it, it would start spazzing out. Remove the wire, effect gone. Be happy that this thing is ultrasensitive. Could be worse, could be a resistive touchscreen.
its not possible it is a capcitative touch screen. I am experiencing the same problem I think it has do with part of our finger is on the case and not on the screen. If i press on it and roll it side to side a bit it will pick up my touch
I have found that using live wallpapers reduces the responsiveness of the touch screen especially around the edges.
Base on my experience with these device in the past, all the live wallpaper does is eat up your cpu horsepower. You want your device to operate at its optimum, yes? Just use a regular wallpaper. Kill all non-essential tasks.
Unfortunately I don't have any productive advice but I can tell you that I bought the p4 case off of steve (great website fast shipping) and a capacitive stylus. Like you described it was totally unresponsive toward the edges. I tried the calibration app and no significant success. After a couple of days use it started registering the touches consistently.
Hi all
My moto Maxx has gone through a lot, but the strangest problem yet started yesterday.
As you can see on the attached video, half of the screen is constantly scrolling. This happens in fastboot and recovery mode as well, so I'm pretty sure it's a hardware problem.
The digitizer still works perfectly, and registers touch where the icon or button should be positioned on the screen. The moving screen also does show everything correctly, just in this crazy scrolling way.
I'm not very hopeful in fixing it, but was wondering if anyone has ever seen this, and if you guys think this is a broken display(and any way to test this?) or a broken GPU. If it is in fact the display, I might consider replacing it.
Some background on all the terrible things I did to this phone:
- Dropped it and cracked screen in September.
- Replaced the glass myself, slightly burned display when removing glass without any consequences (just a tiny mark on the top right, the side that actually still works).
- Dropped again, broke glass again, never bothered to fix it, some small pieces are missing so dust, sweat,.. could've gotten int.
Video:
Most likely the display being broken.
Even when my tempered glass protector is missing chunks the screen starts to funk up. Only worse being the real screen especially the digitizer.
You might be right pjd, or at least screen related.
I opened it up yesterday evening, and I think it might be the cable connecting the screen. Depending on how I positioned the screen and thus the angle at which the cable was bent, it was fixed, the same, or just completely black.
The only thing I have to try to find out now is if it's the kabel, or the connector on the motherboard. Any suggestions on how I could test that are welcome!
Hi all, this is a bit of a long one.
tl;dr - I'd like to improve the fingertip performance of the Shield K1 I purchased recently, which frequently drops parts of swipes. This issue becomes worse when a screen protector is applied, but is mitigated under certain stylus situations, when plugged in, or when 'grounded' against the body of the user...
The screen frequently 'drops' swipes (the path is broken during the swipe) with 2 or more fingers on the screen, when a screen protector is applied (tried both plastic and tempered glass). It also does this when there is no screen protector applied, although far less often.
This makes the device unacceptable for touch-based rhythm games like VOEZ, Cytus or Starlight Stage, or for MIDI/OSC apps with sliders.
The performance is at it's worst when both fingers are near aligned on X or Y axes, and is apparent on apps like "Yet Another Multi Touch Tester", where rubbing the screen with two fingers aligned on the same axes will cause the touches to drop and swap IDs repeatedly. The issue is not apparent in casual use apart from the errant swipe changing directions or not having the right amount of momentum.
Performance improves significantly in a few scenarios:
Unit is plugged in to charge
Unit back is in contact with user (resting in lap, held in another hand)
With Stylus touch blocking disabled, direct stylus 2 is touched to screen during fingertip input, then swapped for a finger (???)
Based on the last point, the device seems more than capable of reliable reading of fingertip swipes, but only after the stylus has triggered some kind of change??
I've tried the included About Tablet touch calibration page, adjusting the touch pressure scaling in the touch.idc. Based on the touch.idc, I assume this is an Atmel Maxtouch digitizer, but I can't find much information on how these would handle screen protectors. They do seem to be able to read touches before contact is made with the screen surface, but I cannot find any way to increase the sensitivity to this point.
I have a Nexus 9 which shares the same Nvidia Tegra K1 chip (albeit dual core, 64-bit), and uses a Synaptic DSX touch screen, that has no such issue even when 2-3 screen protectors are applied at once... of course, this digitizer will not read the directstylus 2.
My main goal is to try and get this touch screen reading fingertip swipes accurately, even at the cost of stylus support etc. Does anyone know of any ways to adjust touchscreen sensitivity to account for dropped swipes like this? Are there any tools for debugging Android's reading of the touch screen at system level? I'd really like to know what the stylus is doing to improve sensitivity...
Any update on this?
I'm also having the same problems with the shield k1. It's especially apparent when my fingers get a little sweaty. The only fix I have so far is to keep them absolutely dry. I sometimes use powder on my hands and will go to the extreme of using latex gloves just to get the touches to register correctly. If you find any other solutions, please update this post.
I think I just ran into my first real problem with the phone. I got a glass screen protector on Amazon, and it absolutely refuses to recognize my fingerprint with the glass on it. The error just keeps telling me to press harder. I never had any issue before without one on.
Took the screen protector off, and now it's back to normal.
I have each thumb trained twice, so recognition shouldn't be a problem at all. I think it's just too thick and it isn't sensing enough pressure to register the fingerprint.
Anyone find a good screen protector that works with fingerprint? I may have to go with a plastic one that won't be as thick as glass.

This is disappointing. When I first looked into this, I found someone claiming to have tested the Oneplus 6T fingerprint sensor with 3 screen protectors on top of each other. I concluded it was not an issue. But now I am seeing plently or articles suggesting that it depends. E.g. "Vivo did mention that only screen protectors of a certain thickness will work with the sensor". I wonder if Nokia will offer or recommend a screen protector.
Also, I don't know if Nokia are using the same sensor as Oneplus, but this is interesting: "[when registering] make sure your environment is not too bright. If possible, you should register a fingerprint in a completely dark environment."
Edit, also spotted this: "We also recommend re-registering your fingerprint every time you add or remove a screen protector."
So as an update, I applied the second screen protector that came in the 2-pack. Removed all of my fingerprints that were stored, and tried to setup new prints.
Took me about 200 tries to get my right thumb registered (not exaggerating), but I couldn't get it to actually read when trying to activate it.
Couldn't get my left thumb to register at all. Just kept saying to press harder. I was pressing so hard I thought I'd break the screen if I pushed harder.
Tried in bright light, as well as a completely dark room. Didn't change the ability for it to register at all.
So overall for this phone, I'm going to say glass screen protectors won't reliably work with the fingerprint scanner. I've ordered a plastic screen protector. Going to try that out, as I'm pretty sure it will work.
I imagine the thickness of glass is the culprit here, due to how the fingerprint sensor works even without a screen protector applied. It seems more difficult to activate than other in-display readers (I have 3 others with in-display readers and they're all incredibly easy to use).
Fingerprint issues aside, I normally go for glass screen protectors because the plastic ones tend to cause more drag when using the phone.
I have generally seen two models. One which is clear and another which has a black border, both with cutouts for sensors, cameras and speakers.
I'm unable to add a link as I'm new to the forums but both examples can be seen on Amazon by searching 'GEEMEE 9h nokia 9 pureview'
Has anyone bought these or similar protectors?
I am interested to know if the black border one covers any part of the screen. I think it looks better on the pictures but in real life I'm not sure how it would look.
I got the Mr.Shield 9h glass and it works fine. The issue with the fingerprint is a software issue. The warning to press harder is not correct. I've verified that the reader will read with normal to light pressure. Hopefully they will release an update that fixes it within the next couple months.

I just got the screen protector with the black borders, and it doesn't cover any part of the screen. I think it looks good. But I was a bit sloppy when I applied it and one of the corners has an air bubble which I can't get rid of.
But since I applied it, the fingerprint scanner is causing me problems. It has problems recognizing my prints

I ended up going for a clear one tempered glass protector. I have a couple of tiny bubbles which was just me rushing as I was excited.
The finger print sensor works fine as long as I get my finger in the correct place but that is a challenge. My thumb is more difficult but still possible. It hasn't been a massive burden though because I have been using face and trusted bluetooth device to good effect.
Hi all,
Two brand new Google-sealed 6a phones just bought from amazon exhibiting the same problem.
The problem is that the phone/screen, sometimes fails to recognize touch inputs, especially at the edges. I just made a screen recording with the "show touches on screen" option enabled for clarity.
Please check the video I've just recorded, here.
As you can see, while I'm repeatedly touching the bottom left screen corner (still well inside the "touch" area), sometimes the phone stops registering the touch(es) for a second or so (sometimes less, sometimes more).
This happens with factory reset phones (two), no apps whatsoever, on A12/A13/QPR1.
If this is a HW problem with my phone, I'll return it and try another one as I really like it (but "can't live" with this problem as it affects usage - especially when using three-button navigation).
Could someone please make a quick test (recording), try to repro this and let me know the outcome?
Thanks a lot!
do you have any protective case or protective glass on the phone?
I've noticed that, after adding case and glass, sometimes touch seems less sensitive near the corners, in my case especially the bottom right one.
Try enabling "Increase Touch Sensitivity" under Settings > Display and check if it does any good.

Same over here, less sensitivity in the corners. I'm on latest October Android 13 version, using Spigen tempered glass screen protector and "Increase Touch Sensitivity" activated
There is a post on Pixel subreddit about this issue, many user are experiencing this issue, both on Android 13 and 12.
oh, wow. same here.
(and all the time i thought it was "just me" (or rather my device), but not worth investigating further (as in, trying to get a replacement, as it’s not THAT often). in a way that’s a relief to hear that apparently i’m not the only one then.)
Same issue. Not all the time, but happens noticeably often every day. No cases or screen protectors yet.
Sometimes my inputs don't register even when they're about a centimeter from the edge of the display. Weird stuff.
Gonna try to enable increased touch sensitivity, see if that does any good.
I don't use any case or screen protector (increasing sensitivity doesn't help).
bought a 3rd unit, this time from Amazon.de (the other two came from Amazon.de) and the problem is still there. This being said, I find it hard to believe this isn't affecting all 6as. Returned the 3rd one... Ridiculous.
