Touch screen not working intermittently when screen lock is not setup - Galaxy Note5 Q&A, Help & Troubleshooting

I have this issue where when I unlock my screen, the touch screen is unresponsive with finger input. S-pen works fine, and all other buttons (volume, home, back, recent apps) works fine too. Just the finger touch stops working.
This issue happens when I unlock my screen 3rd or 4th time. In other words, if I unlock my phone first two times, it works fine but on 3rd or 4th time it will give me this issue. I have to lock and unlock the phone again with power button in order to get it working again.
Interestingly, this issue only happens when I don't have any screen lock setup. If I have any PIN, pattern lock or even swipe to unlock setup, the issue doesnt happen. I suspect that there is some bug with Firmware where it is waiting for the unlock to happen even when no screen lock is setup.
Anyone experiencing the same issue? Any solution for this?

Pocket Dialing again :(

Just got the diamond2 and am loving it. Came from the touch pro. Problem is I have been pocket dialing while its in my leather case. This is not good, as I am a real estate salesperson and it is calling some important people. Does anyone have a solution? BTW, I was using touch lock pro on the touch pro.
Thanks!
hi lorettaboy
you should lock the kets by holding the end call button for a few seconds and that should sort your problem out
I forget what it's called but there is this locking software that will completely lock the phone if you rotate it around the long axis one way and unlock if you do the same the other way.
I have been using throttle lock though. It is like the Android unlock screen where you draw patterns.
If u press the power on/off button for a second, the screen goes off.....isnt it ok to avoid your problem?

I think what may be happening is that the power button is being pressed while in the case unlocking the phone and keys. I had this happen before and still does sometimes when in my pocket.
4 characters: S2U2
Hoping wm6.5 features a lock that's as functional as S2U2.
I personally use http://pocketshield.netserver01.com/ It locks your phone when its closed, and you have different ways to 'wake' it. the 3 that I set it currently is:
1. if the phone is in the case (aka dark) it will not unlock even if phone is ringing, but once you remove it from the sleeve/pouch it will be unlocked.
2. If its night time and the above prevents you from unlocking in the night, shaking phone left to right once will unlock it
3. lastly if I take out stylus it will unlock.

Googled it, light sensor lock sounded interesting, tested it. Never got the light sensor unlock to work. Had to keep tapping the lock button for a varying number of times to unlock. But worse: got catch-22-ed twice within ten minutes.
The first time I got caught with the screen on, the 'turn off' dialog active, and Touch lock Pro active but not clickable because of the turn off dialog. No way to unlock the device and the power button was hijacked by Touch Lock Pro. Removed back cover, took out battery and restarted.
The second time the device locked with the screen off, and the power button couldn't turn the screen on again. No way to find out what happened this time. Removed back cover, took out battery and restarted.
This tool is possibly the least compatible tool with the TD2 you will ever find

Stuck on lock screen.... Android 2.1/2.2

So, I downloaded and launched it perfectly... everything so far i tried is working fine except the lock screen... Some times when i press the Cancel key the button lights lid up but there is nothing on the screen and sometimes it appear the lock screen but nothing happen....
Do someone have any solution to this...
Thank you.
I have the same problem. I have been reading that possibly going back to an older kernel / roofs fixes this problem but have not seen and confirmed reports.
Can anyone confirm this and what version?
Thanks
Same problem at me. Both builds are running very fine for some tine but after that are running slow.I don't know why. Maybe is somehow related with the lockscreen problem?
I have this problem as well i get lucky if i manage to move passt the lock screen and the OS runs really slow it takes like 20 seconds just to open the app screen and the app screen laggs like no to morrow how come so menny ppls can get it to run just fine but i cant it makes me sad face
+1 one for me... I have got a TOPA100, it's almost impossible to wake up the device, sometimes the lockscreen is visible, but it's impossible to move the unlock slider. Usually I need about 10 times and something around 5 Minutes to wake up the device.
Same problem here, would be great if this can be fixed...

For me it's the same and the battery runs only for one hour, I think a (system?)process is running with 100% CPU time. I am new to android, so I don't know where to look.
Same here on an AT&T Pure. Sure would love to get this fixed however I'm reasonably noob to the Android world (not completely novice to linux in general, and I have successfully flashed my AT&T TyTN II thanks to this site.) Fixing this would be a huge help!
Thanks
More specifically on my device I encounter. The following:
- Turn screen off via end button.
- Turn on screen via call button.
HW button lights come on for a few seconds then cut themselves off.
Screen does not turn on at this point.
- Turn on screen via call button again
- Screen comes on with HW button lights
about half the time screen is unresponsive and will not all me to unlock with swipe of finger
Other times will accept input and unlock to the home screen
When unresponsive repeating entire process above will likely allow me to unlock successfully.
Thanks!
Sent from my AT&T Pure using XDA App
same
my screen never wakes up
end up using soft reset to windows mobile
(it could be something to do with startup??)

why do I have to scan my finger twice to unlock?

Hello,
I bought the Moto X4 through Amazon with the Ads and latter hated seeing them so I paid for the difference to get them off. I issue is that Everytime I unlock the using the fingerprint sensor I it just takes me to my lock screen and then I have to swipe up or I have to use my fingerprint again to take to my home screen. It did the same thing while I had the Amazon Ads i always had to do it twice to unlock my device completely.
Does any body else have that issue or is there a way for it to be just on scan and take me directly to my home screen?
I'm on the Android One version on Project Fi, and that is not how mine works. While the screen is off, I press my finger on the sensor, and it bypasses the lock screen to open my phone immediately. Works the same with both fingers I have added.
The G5 Plus had a faster fingerprint sensor.
Is there any way to use my fingerprint scanner only once and directly take me to the home screen instead of the lock screen?
Mine works like that. Just touch it and unlock directly to the home screen. Idk why your didn't. Try to remove fingerprint unlock and set it again. Must work like it should.
My guess is that this is a behavior of the Amazon version that shows ads on the lock-screen, so they have to force you to take an extra step so you actually see the ads.

Extremely unresponsive when trying to unlock with pattern

After upgrading to Lineage OS 15.1, I realize that if I have screen lock set to pattern, then it is extremely hard to unlock when the screen has been off for a while. The screen will stay black while when I'm holding power button the phone will vibrate as if I'm calling power menu. This black screen can last at least one minute. I also set long press to open flashlight when screen is off and that doesn't work. Those symptoms makes me believe that the phone is awake, yet for some reason can't get GUI rendering. Sometimes even when I enter the correct pattern and the animation moves dots and timer away, I can still draw unlock pattern on the hiding unlock dots, and phone will vibrate in a very laggy manner.
Currently I'm running with no screen lock as even "swipe" still cause the unlock process to be very painful. Is this a known issue for LOS or is there a way to fix it? I saw a post says the battery should be replaced if phone is laggy. Is that a possible cause?

This isn't a known problem.
From what did you upgrade?
Which build are you using?
Did you do a clean install?
Which gapps are you using.
Do you have Expanded Desktop enabled?

I was using Stock Android before, but I fully wiped everything before I install.
15.1-20180508-NIGHTLY-shamu
Yes.
I got my GApps from Open GApps, but didn't remember which variant but most likely nano.
I actually have this enabled. I'm gonna disable it and see how that works.
After turning off Expanded Desktop the issue seems to be gone. Though when turned on again after some times the lag is still somewhat exist.
there's a Xposed module fix for this http://repo.xposed.info/module/fr.merams.r.deepscreenoreo

Question Fingerprint sensor unresponsive after update

I'm running MIUI 12.5.6, and since the last update the fingerprint sensor has become temperamental.
Previously, just touching my thumb to the power button would unlock the screen.
Now it will sometimes unlock, but other times I actually have to click the button.
Anyone else experiencing this?
Thanks
