Touch Screen Sensitivity Issue - Verizon Samsung Galaxy S7 Questions & Answers

Hi all,
I just got an S7 as an insurance replacement, and the touchscreen has been very inconsistent when scrolling through web pages, apps (Facebook, Twitter, Tapatalk), and even the launcher.
Scrolling through these sites, the page jumps ever so slightly, but it's enough to give me a headache after 20 minutes. Typing works just fine, though.
Before I call to get another replacement, is this a known problem with the S7s? Or did I just get a bad refurb?
- I'm coming from a Nexus 6
- I searched the forum
- Running stock Nougat, not rooted or modified
- I performed a factory reset after Nougat update, problem still exists
Thanks!

Horrible Stutters and Freezes on New Replacement Device

I got a replacement device with stock rom recently and it suddenly started to experience stutters, lags and freezes frequently. For example, I'd be typing on the keyboard and suddenly everything stops responding. It happens in Chrome, randomly whenever I'm using the keyboard, and basically throughout the rom.
One solution is for me to wait 2 minutes and it might suddenly start responding. But the only sure solution that always works is for me to lock and unlock the device a few times (using the power button) and everything goes back to normal for two minutes until it lags and freezes again.
Thoughts anyone?
I had all the same previous apps on my previous Nexus 4 and had no problems....
RMA karma.......
........
These are tough to troubleshoot, but to narrow it down to hardware vs. software, I'd do a Factory Reset, and test, before signing into your Google Account and d/l'ing all your apps. If it works fine for a time/day, THEN sign in and only add a few apps (set Market auto update/restore off for the time being). Naturally do the apps your require daily first, and check stability for some time before adding back your 'fluff' apps. Often a poor app can be the culprit.
This happened to my nexus 7. I had it for about a month and i noiced that it started lagging really bad. Watching a video was just horrible and the responsiveness of it was bad. I just thought that it was a app or the custom rom i was running. I factory restored it and locked the bootloader and it still lagged. I just RMA'd it and i got a new one that was much better.

Actually the keyboard is screwed up too. In gesture typing it randomly draws lower on the keyboard than I'm actually drawing. I'm guessing that it is a hardware or touchscreen sensor problem. I did an RMA and Fido Asurion promised to have a replacement to me by July 3rd. The only problem is that they only seem to send out refurbished phones for RMA's.

Yeah..if it's acting up after a Factory Reset, then no amount of fiddling will solve it. Sorry man!

[Q] Phone sensors unresponsive for a few secs when receiving call.

Hello everyone. I've done a few searches on here but haven't found this exact problem. Relevant details without extra background info are in bold.
My wife and I each got an S4 with Sprint's recent BOGO promotion. My phone has had no issues. It came with MDL in the box, which I updated to MF9 via OTA, flashed TWRP via Heimdall in Linux, rooted, and installed the hotspot mod.
Her phone - completely stock MF9 and new from the store - has had problems, one of which I've so far been unable to fix. (How I wish it were mine. I develop for Android, but this is much more of a pain for her.) Hers already had MF9 at the store. It had the Google Services Framework/Core Apps runaway process issue with heat/battery drain from the start - which I fixed. However, it also has unresponsive sensors for ~3 seconds when receiving a call. It's almost as if there's some lag in activating the sensors. The phone is otherwise snappy with no other lag noted.
- Hard reset has been tried.
- The touchscreen is unresponsive during this time, though the display functions.
- The gesture for answering (when enabled) also does not work.
- We haven't tried enabling the home key to answer, but this will be next.
I've seen this before with Android a good while back. It was an inherent problem with Gingerbread on many phones. Haven't seen it pop up in Jellybean at all. In trying to diagnose, I've ensured that all bells and whistles are turned off. No air gestures are on.
We'd really like to get it working as it should. Has anyone else experienced this? Any advice?
Many thanks!
I believe this is more of a stock software issue. I have had the issue since day one.
When I turned off svoice and some of the other added features most of the lag disappeared. Svoice is pretty good at creating lag as far as ive seen.
Voice response seems to create th lag as it is awaiting a voice command from you.
This is what I have noticed anyway.

Device occasionally stutters/unresponsive. Defective?

Ever since I first powered up the device and went through initial setup, I noticed there were moments where the device would stutter/hiccup and not respond for a split second. I did a factory reset and it still happens.
Anybody else having issues?

Not with the S7 itself, but I am getting a ton of scrolling lag on the chrome browser. Luckily the only thing that is lagging for me. Everything else is super fluid.
I AM using Nova launcher though. I hated stock S7 touchwiz launcher.
The only lag I've had is in package disabler pro scrolling through the list. No other apps are having issues for me. Might be worth returning/swapping out.

Yes, it's happening a lot in Chrome. Tinder too. It also happens every 5-10 seconds or so when using the Gear VR.
I too am using Nova.
Mine doesn't stutter or lag. If I were you I would swap it out.
Swapped my S7 and it's still choppy, but it seems to be dependent on the app and not the device. Not defective.
Same here, I got me first S7 edge on the 4th of March, then swap it out due to defective screen (white spot on lcd) few days ago and now can't play video from websites, videos will sound like in fast forward mode, specially Facebook

Nexus 6p 7.1.1 scroll lag

I'm running stock android 7.1.1 on a Nexus 6p and there's a dramatic lag in scrolling response. When the screen is scrolling quickly and I put down my finger to stop the scroll there is a huge lag before the scrolling stops. About half a second or more. It seems to occur in all apps (and even system settings menus). I've had this problem since buying the phone a couple weeks ago. It's driving me nuts. I never have this problem with my iPad, MacBook or even my ancient nexus 4. The odd thing is that if instead of just putting down my finger I drag my finger slightly (in any direction) then the lag almost disappears, but obviously that's a very awkward thing to do, especially when none of my other devices require it. Does anybody else have this problem (and hopefully a solution)?
I've talked to Google customer support. They told me to clear the cache of every app (yes that does take quite a while) and to clear the partition cache. This did not resolve the problem and now they want me to do a factory reset, which apparently is the last step before hardware warrantee measures. I'd love to know if this is a common problem.

You aren't the only person who has experienced this issue but I haven't had it happen. I don't know if anyone found a solution but if you do a search in this section you should find a thread very similar to yours with a lot of responses. I think some people experienced the issue after updating to 7.1.1

Thanks, I'll have a look. (Tried searching before but didn't find anything.)
For me the problem predates 7.1.1
I found the source of my scroll lag issue. I sometimes enable the magnification gesture in the accessibility settings (because I often use a particular transit app that has insanely small icons). I realized that when I have this setting turned on the scrolling gets laggy. Turning off the magnification gesture seems to solve the problem completely. Not sure if there's any workaround other than disabling the gesture setting.

Ghost / Phantom Touch

I've had this phone for a while now and I've had one issue that is persistent and very annoying.
I get a ghost or phantom touch when scrolling. Basically, I'll be scrolling through a webpage or Facebook or anything really and as soon as I put my finger to the screen and swipe up the phone will register this as a touch. This causes all sorts of issues like posts opening that I did not intend on opening or misdials.
Does anyone else have this issue? I'm on stock (rooted) with the september security patch. I did a factory reset today hoping that that would fix the issue as I was on TruPure before the stock rom I'm on now. I still have the issue, the factory reset did not fix the issue.
If anyone has any ideas or a solution, I'm all ears.
Thanks.
Me too, maybe. Upper left quadrant of screen becomes crazy. Touches produce random responses if not wild responses. Think software as reboot fixes. Sometimes walking away fixes it. Happens after phone has been actively in use awhile. Maybe memory or buffers are full.
I am clueless.

I'm experiencing the same exact thing, and yes it does seem to be focused in the upper left area as well. I replaced my screen a few months ago and thought it was the cheap screen failing. Are you on original or replacement screens?
New phone. Unlocked, TWRPed, systemless Root, stock ROM.
