[Q] Lock screen and messaging issues

Hey guys,
On my OGP, I have noticed that once I press the side button to unlock the screen, the touch keys light up instantly but the actual screen takes 1-2 seconds to light up after the button press. It may have gotten worse over time, or that may just be me being paranoid. Also, in messaging settings I experimented with messaging skins, and those seemed to lag my messages a lot (like when I clicked on a conversation, it took 2-3 seconds for the conversation to load, whereas before it was instant). When I removed the skin and went back to the default one, the lag still persisted. If anyone knows how to fix these issues, I would be grateful! My device is stock unrooted with value pack update, US AT&T. Only settings I changed was turned on quad core optimization.
Thanks,
killer

Fixed the lock screen lag by removing my dewdrop screen animation. Leaving it at basic drastically increased speeds to easily under a second. Now for the messaging lag...

Home button continues pressing?

I've had this issue before on my LG Power (Straight Talk branded LG Leon), running on Lollipop 5.0. No matter what I look for I can't find anyone who's experienced similar issues.
It just happened last night on my 5-day old Nexus. I could not open any of my folders to access apps. As soon as a touched a folder, it briefly showed the animation to open it, and it immediately closed. Whenever I selected a widget or the app drawer, they would immediately close as well. When I attempted to swipe down the notification/quick settings shade, they immediately closed themselves. Turning off the screen resulted in the screen immediately turning back on, albeit locked. I was even having trouble turning the device off because the 'Power Off' menu would disappear right after it popped up. Eventually I was able to time it right and was able to power off. Since I restarted I have not have any issues.
Any idea what gives? I'm unrooted, locked bootloader, everything 100% stock, running MM 6.0.1.

the only explanations i can come up with are:
-accidental touching the area in some way (unlikely)
-getting some substance stuck on the screen in that area (unlikely)
-a faulty touch panel (unlikely and very specific defect)
-a hickup in the software (again unlikely)
then again, if the OS (for whatever reason) thinks the home button is pressed, on default it should not only pull you back to the homescreen, but continue and send you right through to google. the conclusion of which would be, that this UI area is triggered repeatedly rather than continuously.
keep an eye out for what could have triggered it in case it occurs again.
check your settings what build exactly you are running (settings -> about phone -> build number).
ans lastly, if it happens again, you should still be able to hold your power button to hard-reboot it (no further interaction with the UI required).

Try to clean your screen also with a towel

That is extremely weird. It really sounds like a faulty digitizer, but you'd be the first... Maybe it's a rogue app, but unlikely.
Were you doing something before this starts to happen?

I haven't noticed any consistent apps or behaviors when this would occur. This most recent time, I was low on battery (10%) and I had just flipped on my data.

fyi. you could also just press and hold the power button, for 10 secs, for a reboot ( might come in handy when the screen isn't working properly).

appreciate the tip! I'll keep this in mind if it happens again.

Finally was able to capture a video. The issue occurred after I was playing around with Open Camera and it crashed. Holding down the power button didn't work when this glitch is happening.

What's the icon on the lock screen, top right in the status bar? That behavior is unusual if it's not a screen defect. Are you using any apps that monitor battery, a task killer, or maybe a security monitor app?

The icon is a picture for my user profile on the phone.
I don't use anything like that. I had Clean Master installed briefly but it's been uninstalled for a couple of days now.

so it seems like this issue pops up whenever the camera crashes. happens occasionally when using the camera shortcut (double power tap) or in an app that uses the camera.

It's got to be software IMO. It didn't happen when you went to Google Now and your Recent Apps. I'd try uninstalling the Open Camera app first. Do you have Face Unlock active by chance? After that I'd FDR...

right, that's what's confusing me. i did a factory reset last week, set up the phone as a new device. haven't installed a new camera app, just the stock google camera. the issue occurred again last night when using an app called Shopkick, which accesses the camera but crashed.

Scrolling freeze on chrome

Open a website,start scrolling and suddenly it won't move. Pull down the notification bar slightly and I can continue to scroll again. Probably a 120hz setting compatibility issue but curious if anyone else has this problem too?

Seen that too but also in Play app

Have it too. Seems like I either wait an undetermined time for it to unfreeze or pull down the notification bar to unfreeze it.

Well, glad I'm not the only one, although it's really annoying when it happens.

Mine also does that many times but that's more like the chrome's problem since the phone itself runs smoothly in every other app.

I believe I'm getting the same issue in other apps as well. I'll be scrolling, but if I press the home or back button on the navigation bar, it will lock up for like 20 seconds before something crashes. The common error is that System UI has stopped responding. Been having this issue, and quite frankly, it's making me want to give iPhones a try again...

That's not all. It opens some sites for a very long time 1-2 minutes, while in the same time as a Samsung Browser it opens in 5-10 seconds. It is very strange.

I use Brave rather than Chrome but get it here as well. Only in Brave though. I normally swipe back to home screen and go back in to unfreeze it.

Question Odd scrolling behavior

Unsure if anyone is experiencing this issue or it is just my thumb.
When I am holding the phone in my right hand scrolling down the screen with my thumb reading or moving through an app, i will get a too frequent misfire that bounces me back to the top of article or app screen.
My thumb motions are downward. However, the screen is obviously interpreting I am flipping upward.
Is there a setting that might change this? I do not have increased screen sensitivity turned on. Is there an elasticity setting that may be causing this?

Curved screen can still register palm touches just holding the P6P.

same issue
I use one finger to turn the page and my palm is not touching any screen edge

some apps are causing weird scrolling issues. the reddit and twitter apps (can be) problematic right now. I've seen at least 4 cases where removing those apps completely and using alternatives (like Relay and Albatross) has resolved issus. so it could be it...what app are you having an issue with? try chrome in safe mode , see how the scrolling is (safe mode only works with google apps, and it turns off network so turn it on if you do try it)

Thanks for the insight. Reuters News app, Brave Browser, NYT app, pretty much any app when scrolling down reading.

any changes in safe mode? only google apps work on that mode but worth a try

Honestly, I don't see how to get into safe mode on the P6P.
I can get to the menu w/ power button + volume down. What am I missing? It's been a while.

the power menu can be brought up in the notifications menu (Swipe down twice, you'll see the power icon). from there just long-press on the "Restart" button.

Thank you!
As you mentioned, in safe mode I can't try any of the apps where I experienced the issue.

Question Touch/tap problems

I'm having problems with my Fold 4 not registering taps. I tap a space on the screen and nothing happens. I do it several more times, and finally it responds. I haven't seen a clear pattern yet, because it's somewhat intermittent. Has anyone else seen this problem?
I'm slightly suspicious of the Microsoft launcher here., but I suspect that's because it gets the majority of my taps, it being the launcher. I haven't had that problem in the past.
Just a minute ago I sat down to make a video of what I was seeing in case I thought an exchange might help. It happened on the first try, and I wound up having to press it five times with escalating pressure to finally get it to react. For the record, I have not seen a correspondence between pressure and the problem. I think I just naturally start pushing harder and when it works, it feels like it was more pressure. But when the problem isn't occurring, it takes very little pressure to register a tap.

Not using the Microsoft Launcher, but I am using SwiftKey, and I do have the same issue, especially with the space key. Mostly with the outside screen BTW.

Ah, I should have been more specific. Yes, I've only seen the problem on the outer screen so far. And I'm using gboard for my keyboard.

I've had a similar issue but it seems to have gotten better. Being intermittent makes it hard to pinpoint

I initially transferred apps and data from my Note 20 and was having issues on the outside and inside screen of taps not registering. Finally did a FDR and set up from scratch, haven't had the issue again. I always setup from scratch and took a shortcut this time, lesson learned!

I actually did an FDR last yesterday to try and solve the problem. Naada. It was still there for me.
I'm currently using Samsung's OneHome UI to see if it's something with the MS Launcher. Good god, I hate their launcher!

It feels like the sensitivity on the outer (cover) screen is too low, and combined with much smaller keys on keyboards (I use GBoard) there are plenty of missed hits and no response. Try turning on touch sensitivity and see if it improves ( Setting -> Display -> Touch Sensitivity. Mine went a tad better. I also changed the layout preferences to 'normal' keyboard height and most of my misses are now gone..

I'm having same issue but not with the keyboard but with tapping on apps on the home screen. I'm able to almost reproduce it every time in the middle of the screen. Is there any update on this issue?

I've got same issue that a tap on a app gets no action. Happens occasionally. Must be a bug.

After a factory reset mine has come back too. Hopefully we will get some bug fixes with the September security update.

Same. I never have a problem in application, it's only when I'm interacting with the launcher.

I think the issue is with the refresh rate dropping. I used the galaxy max hz app and increased the base hz on the phone and I'm noticing response being much better now.

I also have this issue on my Fold 4's cover screen. I've always used the debug option to show where I touch, and when my touches don't register I still see the touch indicator, so I can only assume this is a software issue not deciding what to do with the touch. I think One UI might be overly sensitive for gestures, and detects taps as drags/swipes. A mini swipe on an app or folder on the home screen for instance won't do anything (which happens to me frequently).

I've had that problem quite a few times as well, not enough to drive me crazy but enough to be slightly annoying. It only happened when taping on the bottom of the screen. It often registered my taps as a swipe up. I saw the homescreen starting to go up slightly as if it was going to enter the drawer. Then one day I realized it was my way of tapping the screen that was the culprit. The way I hold my phone makes me ever so slightly swipe up as I tap the screen, but only when taping the bottom part, if I tap anywhere else, I don't tend to move my finger up as I tap. Of course, I'm talking minuscule amount of swiping here, probably less than a millimeter. It's just the way I hold the phone and move my thumb, it's personal, and I think everyone is going to have a different experience depending on how they hold their phone and tap the screen. Anyway, I'm not saying "you're using it wrong", because I think it's a problem samsung must fix, as I don't have that problem on any other phone. Probably too sensitive. I just tried to reproduce the problem as I write this message, and succeeded twice in less than 20 tries, so definitely the problem is still there. It's just that now I tap straight on instead of "sideways", and it works just fine. Just a workaround, I know...
Edit: on the cover screen, of course. Inside screen works fine with crooked taps.

Glad im not the only one. On the outer screen i have had times where I have to tap something 3 times for it to register... I never had this issue with my Z Fold 2
