[Q] Scrolling lag - Nexus 7 (2013) Q&A

Whenever I have my finger on the screen (such as navigating between home screens or scrolling down a web page), and I am moving it along at a constant speed, instead of the page following my finger smoothly like it does on my galaxy nexus, it kind of shuffles along. As soon as I let go of the screen and just let the page scroll freely, or just flick between home screens, the animation is incredibly smooth. Its almost as if whenever my finger is on the screen the fps is lower. I have tried multiple Roms and kernels, and some have made this issue less noticeable, however none have completely solved this issue. I'm starting to think its a hardware issue. I have noticed how bizarre the transistors appear and how spaced out they are. Is there a fix for this? Is everyone else experiencing this same issue?
When I say scrolling, I am not referring to "flicking" the pages back and forth or up and down, I am speaking specifically about how the images on the screen are reacting to my finger when it moves across the screen.

Try force close & clear data the home or launcher... Sometimes it works... But I don't know if it help

That may help with the launcher, but it seems to be a more universal issue.

I posted a thread in the General section a few days ago about this problem too. Combined with the input latency, it is incredibly irritating and really needs to be fixed in an update.

Fast scroll in browser

Hi all. I've been busy playing with my new toy now for a few weeks and love it.
One thing I have seen happen on a few occasions, but cannot find any details of, is when I am using the browser and flicking the page up gently as I am reading, it takes off at super speed on it's own and scrolls right to the bottom as if on auto pilot!!
Is this an actual "feature"?
I have tried to reproduce it, but I just cannot find how
Then when I am least expecting it, I give the screen a gentle flick, and away it goes again!!
Haha, yeah... it happens when you are scrolling in a direction and suddenly stop keeping the screen touched down on. Let it go and whoosh! You have to quickly press+hold the screen and move it a little in the opposite direction to make that stop or it continues. Can be very annoying at times, but very helpful to me at times too. It's that repeatable for me that it almost sounds like an intentional feature. IDK though.

[Q] Does anybody else have these lag issues?

I can't figure out whether I had this lag problem when I first got my GN. 99% of the time my phone runs absolutely beautiful, perfectly smooth scrolling through menus and on the homescreens.
The only two places I do encounter lag are when I press the home button if I'm on a screen other than the main one (eg I'm on the left side screen and press the home button to return to my main homescreen it seems quite stuttery). And the other place is in the settings menu, when selecting any of the options it lights up blue but when it returns to it's normal colour before going to the appropriate setting it seems quite stuttery as well.
Neither of these are massive issues obviously, but I'm just interested in whether this is standard and it's always been like this or if by flashing other ROMs to my phone (currently running ARHD 2.1.2. but I've had these since I flashed the first version at least) I've caused this behaviour.
I'm rooted but running completely stock and I have lag issues occasionally as well. Mine occur around 30% of the time.
I'm hoping a software update can address this, because when all of the Nexus reviews were going up a month or so ago, there were no complaints about lag. At that point in time I'm fairly certain the reviewers had Android 4.0.0 installed.

Touchscreen scrolling and swiping problems?

Is anyone else having issues with what appears to be dead areas when scrolling, swipe texting or otherwise using your phone? In typing this message the phone just lost my finger on 4 occasions. When scrolling webpages it often just stops and clicks an area where my finger was. I'll get occasional double clicking on things when I do try to click. I have trouble purposely replicating my problems but in regular us it is driving me nuts. Because I can't constantly replicate I'm not sure trying to take the phone back will be successful. Anyone else having issues? Could there be something I'm missing somewhere?
Sounds kind of mean but I hope your issue is isolated. I saw the ifixit teardown and the ease with how the digitizer came off of the glass has me worried about the longevity of the digitizer.
Happening to me insanely often on my regular Pixel.
This happens to me occasionally. Sometimes, when typing it spams v and b. If I find anything I will fill you in.
Yes, I'm having this problem with my Pixel. It happens across all apps, even in Settings. Generally it happens if I start scrolling after not touching the screen for a little while.. for example when reading a news article. The scrolling freezes, and I can move my finger around on the screen and it doesn't react, but then it might pick up my finger again and the screen jumps around or clicks on something even though I've not lifted my finger from the screen. I tested it in safe mode and it happens there also. I even got my original device exchanged, and the same thing happened immediately on the new phone. I've been in touch with Google Help this morning and they've confirmed it's a software issue. They've asked me to submit a bug report. It'll help them if more people report the bug though and they have more data to fix it, so if you're experiencing the same issue, please report it! You can chat directly to Google support through settings on your Pixel.
Haven't had any issues but I know the google keyboard can be a bit glitchy at times. I used to have a nexus 6P and I would get weird issues with that keyboard as well on that phone. Getting them less on my Pixel though.
Having issues with typing on my 6P, it's so odd as sometimes I can not type when in desktop mode and sometimes not when in mobile. Switching the webpage screen mode and also doing a soft shut off on the phone and coming back both fix it temporarily. Thought at first using a different keyboard app might help but what app it runs does not solve the problem.
Same problem here. Google pixel
Happening to me as well. Did a factory image flash and it seems to have helped but still happens once in a while. I notice it the most when I'm using reddit sync. Seems to just happen too frequently.
Just an update on this... After doing a few steps suggested by google tech support like, test on safe mode, factory reset using bootloader method, etc... They just replaced my unit. I'm using a new one today and problem is not existent now. I would assume the problem would be hardware.
To be honest, I'm quite happy with their tech support...24/7 support and the staff are really competent. This in my opinion, is worth the high price of the pixel. Good job google!
I have the standard Pixel, and I too had issues with typing (occasionally wrong letters or spaces would register), and dead areas in the top corners of my screen when trying to open apps. I was going to return it one day after confirming that the dead areas at the top of the screen were persistent, but for some reason I decided to grab an App from the bottom of the screen and move it by sliding to the top area. Instantly this cured the dead area issue, even after I moved the app back to the bottom of the screen. It's as if it recalibrated the touch sensitivity vertically as it stopped erroneous spaces when typing too.
Pixel 2 one handed thumb scrolling issue
I have the pixel 2 and I have intermittent scrolling issues when I hold it one handed and try to scroll with my thumb. I realized it's because the base of my thumb is brushing the opposite side of the screen and preventing it from scrolling freely.

You should probably post about that in the Pixel 2 forums.

Scroll lag/stutter/phantom touch

Anyone else having an issue with scrolling? Sometimes scrolling is smooth as butter, but occasionally it stutters or doesn't fling as fast as it should. I've even had it scrolling in an app in the opposite direction that I swiped, or seemingly not register a touch. Rarer, but has happened a few times, I feel like there was a phantom touch on the screen. Like a part of an app opened or closed as if I touched the screen and I had not. I'm really hoping I don't have to go through an exchange process.

I noticed this, especially when I'm scrolling and images are being loaded. When scrolling threads with the XDA app it stutters when avatars are being loaded.

Lag
I have lag so far on Bluetooth streaming in car...really freaking annoying...and also playing games. I love this phone but they need to fix this asap (8gb ram 128gb storage)
This seems to happen when apps are loading things - Facebook, heavy web pages, etc. Try scrolling in your contacts app - I bet it will be smooth.
I have experienced the "phantom touch" by way of apps just closing out of nowhere like I pressed the home button when in fact I hadnt pressed anything at all. It happens most with Chrome but I have had it happen with others. The first few days I couldn't believe how smooth the phone was (most likely because it is quite the upgrade from any phone I've owned since the S5) but recently I notice lots of little hiccups and stutters.
The main thing I notice is it seems like there is a random dead spot in the top left corner where touches do not register. Examples of this are the menu in Magisk and the X to close window in SoundCloud. Sometimes it registers, sometimes it doesn't and takes multiple tries before it will. Its a pretty big area for touches to not register and it happens multiple times a day.

Sorry to bump an older thread, but do you have these touch issues constantly, or only in certain situations? A couple of weeks ago I noticed my touch screen gets some issues when the phone is charging, and goes completely crazy when my phone is charging and I ground myself electrically. Touches are not registered, trying to scroll is interpreted as a tap, scrolling is all over the place because touch recognition isn't smooth and long taps are hard to do.
But I also have slow scrolling speed in Facebook and Facebook messenger when not charging. Other apps scroll just fine.

Pixel 2 XL - Touch sensitivity issues?

Hi there,
So I finally got my beautiful panda Pixel 2 XL and I absolutely love it, except for one thing - touch latency or sensitivity.
UPDATE
If you're having similar issues, be sure to "+1" the following thread on Google forum and also comment: https://productforums.google.com/forum/#!topic/phone-by-google/3XDqX3LgpvQ;context-place=topicsearchin/phone-by-google/category$3Agoogle-pixel-2%7Csort:relevance%7Cspell:false
I took off the glass screen protector and I'm now using it naked. I feel some improvement BUT this is still far from perfect. I was expecting such phone coming straight from Google to blow me away in terms of touch latency and such, but for now it feels like my Oneplus 3 is actually more responsive. Super strange.
I'm not entirely sure what's going on, but basically I feel like I'm having a hard time registering a touch on the first try TOO OFTEN. Sometimes I would even try to scroll up or down a web page and it wouldn't register for a few tries.
Things to note I'm NOT using the screen naked, I'm rocking an AmFilm tempered glass screen protector, it's a dot matrix kind of screen protector, one that doesn't actually stick to the screen entirely, only at the edges. Could this be the issue?
Is anyone else having similar issues with or without a screen protector?
Again, other than that, the device is perfect. Also very minimal blue shift that doesn't bother me at all.
Thanks for your help
How is the sensitivity with the screen protector off?

I know it's silly, but I don't want to take off the screen protector because I got it aligned perfectly and the only replacement I have is a different type - a tpu film.
The thing is, I didn't even have a chance to try out the phone without a protector since this was the first thing I did when I unboxed it :/
Was mainly wondering if anyone else is having touch screen issues with a tempered glass screen protector of any kind?

You on latest 8.1?
I notice some touch sensitivity issues in the far edges of the screen. I'm not using any screen protection at the moment.

Yep, I'm on the stable 8.1 all stock not rooted or anything.
This is mostly apparent when scrolling, I would sometimes scroll down and the page would move downward and sideways altogether, as if it is registered as a swipe to the side with a scroll down. Same when scrolling up. Very annoying.

What's your Animation Scale set to in Developer settings? I changed mine to .5x and noticed improvements in scrolling & response...

Yeah, definitely. I'm already on 0.5 scale unfortunately so this can't be it. Thanks for your help anyways! Appreciate it
Same problem after the 8.1 update answering a call is so hard. even unlocking my phone with a swipe up is very difficult. Swiping away notification takes 3 tries. I'm actually regretting the 128gb with google protect! So much money with so many problems. I came from a GS7 edge and it was way better performance wise then this phone. Feels like I'm just a beta tester for google. Seems like every update fixes one thing and breaks 4 more.

Agreed. I actually miss my Oneplus 3 in terms of performance and fluidity. I can't type or browse with this phone without having weird glitches. Sometimes the tap wouldn't register, sometimes it's the scrolling acting up.. Very annoying as I said
I'm having similar issues. Randomly my phone decides I touched somewhere in the middle of the screen I didn't at all, or when scrolling down a list eg. YouTube or Twitter, it suddenly jumps me back to the top as if I swiped down at super human speed.
More over the most consistent issues I'm having is tapping on the edge. Eg. The elipsis (3 vertical dots) when looking at 'my channel' or a playlist such as my attached screenshot. I cannot touch the elipsis at all even with a stylist.
My device is Google Pixel 2 XL, 8.1.0, build OPM 1.171019.011
P.S I'm using the phone 'naked', no case, no screen protector.
Damn. Looks like we've got an actual issue here.
For me it is most consistent when I'm scrolling up or down a list that can also go sideways, like Instagram Stories stickers for example, or an email on Gmail where you can swipe left to get to the next message. It will randomly go right/left when I'm actually swiping up/down.
It also happens to me, sometimes, while scrolling up or down, 5 or 6 times successively, it doesn't recognizes one of the touches.

Nimrodiny, would you mind trying to go on the YouTube app, and either on your 'my channel' list or a playlist try to tap on the ellipse?
It's completely impossible for me, every time either nothing happens or it decides I touched the video itself to play it. I'd like to know if my issue is not unique.
Addendum: I tried viewing this page in desktop view mode in Chrome and zoomed in. I was able to scroll up and down over and over without any side scrolling happening at least.
I have noticed sometimes it freezes when loadng a web page thought it was chrome but updated to the beta.
Same effect, something is off with the touch sensitivity but not always.

Yep. I can definitely tap on the ellipse on YouTube via my channel.
BTW, just made a scrolling comparison - same website, same browser, on my Pixel 2 XL vs the OP3 and... The OP3 absolutely killed it. It was way smoother and never stuttered while the Pixel had tons of stutters and misreading of my swipes
Thanks for testing Nimrodiny. In that case I best go back to the store and exchange my phone, as edge tapping is definitely broken for me.
Ya. Happens to me.. not acurate touch.. try touching that 3 dots on YouTube app on full screen ( where u change resolution of youtube play back)
Ufff fed up with this.. display, speaker, touch.. how many more
I came from OnePlus 3 n got panda pixel 2 xl. I faced some touch sensitive issue while typing n sometimes browsing. M using my pixel with iq shield screen protector film. I did a factory reset it did helped with swipe issues to some extent. Also I disabled vibration n sound for touch and feel bit better while typing. Mostly while typing I had hard time pressing space bar , most of the time I had to press twice to register a space. lts like phone is unable to keep up with my typing speed(m not that fast though). It doesn't feel like using a flagship phone . I would say touch is good but definitely not great.
Other than that I face no display issues like screen burn in or weird sound issues . Ya blue tint is there but it's part of the display not an issue.
I would suggest try factory reset once n disable sound and vibration on touch and see if it does help some how.
