Hey there,
for about two weeks now I am noticing this strange issue: When I want to unlock my phone I touch the finger print scanner, the capacitive buttons light up but it takes sometimes more than a second before the screen lights up.
I am on Android Oreo, TWRP, S-on, stock firmware, magisk. This setup worked perfectly for many weeks now. I already cleared the cache partition.
Rebooting helps for a short while.
Does anybody have the same issue or has suggestions how to solve this or an idea what the cause might be?
Thanks a lot in advance!
Do you have a live wallpaper or an app that interferes with the lockscreen?
No and no.
I stumbled across another thing: using SD Maid improves the situation for a short while. Cleaning up the data bases seems to do the trick - for a half day or so...

hi,
I'm not sure when exactly this issue started on my phone, but I updated my touch pro with the chevron updater and have quite a lot of apps installed.
after several seconds workling with the phone, the touch screen stops working while the phone acts perfectly normal. I can use the keyboard and tilt the phone but I cannot use the touch screen anymore.
By turning the phone off and on it works again.
has anyone experienced a behavior like this?
I noticed my touchscreen becoming unresponsive when loading particular websites. Even had it freeze once (only time it ever froze on me)
What were you doing when it does this? Do you have the multitasking reg edit on?

I know this is an old thread but this is the only reference to the exact same problem that I'm having. I'm having difficulty putting this down to hardware as the screen becomes responsive again when locking and unlocking which might point to software.
It could be a hardware issue that is resolved by locking then unlocking the phone but I don't know enough about the construction of it to have an opinion.
The advice I've had from htc is to wipe the 'phone and start again but I don't expect that to solve it (especially as their call handling system refers to Window Mobile 7 - the second large commercial organisation I've seen that on in recent weeks without looking too hard!).
Has anyone else seen this since the original post or @exilkubaner was a solution found to your problem?
Hi,
I have exactly the same problem. I hard reset my HTC 7 Pro, but no success, my screen doesn't respond until i lock/unlock the device.
So, any one have resolved this issue since the first post ?
Regards
Had the same issue, but I didn't have any roms installed.
Brought it in to Sprint and they found that I had a fried ribbon connecting the screen to the phone. Replaced under warranty.
It happened again, I determined that it was caused by my click in belt clip/holster. When I pull the phone out, it pulls the screen away from the keyboard a bit.
^Wow. Nice find. I'll have to be careful with mine now as I could easily run in to the same problem pulling it out like that.
After installing Lollipop, everything became unbearably slow. I've tried flashing multiple ROMs, both Lollipop and Kitkat, but everything remains so slow: the actual boot-up process and the ROM itself. Does anybody have any ideas about what can be done about this? In fastboot I see hammerhead D820(H) 32GB; HW version rev_11; Bootloader version HHZ12d, Baseband M8974A-2.0.50.2.22. Lock state is unlocked. Any suggestions will be highly appreciated!
Wipe cache and see if that helps and disable Chrome's integration into the app switcher. Also get rid of Facebook and FB Messenger.

Instead of Lollypop try some LSD
Thanks. But it is that slow even before any of these apps are loaded (e.g. after I do a factory reset and flash a new rom). Is it possible that Lollipop did sthg to the hardware? If so, how could I find out? Just to give you an idea about how slow exactly it is: when I am typing 5 letters at normal speed, it takes until the fifth letter before the first letter actually displays on the screen. I should also note that when the screen goes off, I can no longer get it on again without a reboot...
I'm still trying to figure out what this might be. I first thought my problems were similar to those that others have described, but I now think they be different. Here are some of the issues I'm encountering:
when I boot up the phone (whether in kitkat or lollipop), the initial android (animation sequence is already incredibly slow
there are all sorts of strange things happening with my screen. When it goes to sleep in Android, I can not wake it up anymore. When it goes to sleep in recovery, and I push the power button, the screen goes (again after some time) from pitch dark to a slightly 'lit' dark, but it never displays anything, and I have to reboot again to get the info on the screen. Also, the screen is even slow in twrp - when I swipe to do a factory reset, for instance, there is also a noticeable lag.
I have tried with various ROMs (both stock and not); with ART and Dalvik, etc. but none of these changes seem to affect the slow screen issues
Does anybody have any ideas about what the problem might be? I should also add that we had the screen replaced a few months ago - could that have something to do with it?

Probably the replacement screen has been reconnected poorly. There's nothing you can do on software side, for me, it's more like a hardware problem.
Charged phone during long flight, and read a lot. After landing, fingerprint sensor was like 50%. Reboot, no improvement. Menu for fingerprint settings...click and lag, nothing. Reboot. Now fingerprint menu is gone. So is home button!
PITA....got Leedrod tweaks for Navbar! Dirty flash, and no fp sensor. Clean flash, no fp sensor. Restore stock system and wipe data...doesn't even ask for fingerprint on setup. It's like the hardware disappeared. Tried force stop fingerprint software from settings, apps, show system, and clear data. Reboot again...gone.
Wakeup next day, reboot and it works? So flash Leedroid, and restore my Nandroid data...all good now.
So what can cause the loss of the hardware like this? Some kind of security lockout? Or hardware fault? Didn't get wet. Still in 30 day period...should I send it back?
Has there been a software update from htc for the fingerprint sensor?. Things usually go mental when updates occur..

No changes from my end regarding software. I guess it's possible something got corrupted with flashing and stuff. Seems to be a common problem on other devices:
https://forums.oneplus.net/threads/...vailable-issue-started-out-of-nowhere.450914/
They describe same situation as me. Hardware just disappears, and the related menus.
Thought mine was fixed, but it happened again last night. I let battery fully drain, then fully charged, rebooted, and it's back again? I did walk around in the rain last night...could be related.
Wish I knew if this was software or hardware issue. Guess only way to know would be to RUU.
Another weird thing: I have to enter a pin now when phone boots up. Not on the lock screen, but on a separate system prompt. Same thing when I start TWRP. Could be a security issue? Or a conflict in PIN settings?
Any help appreciated!
There's already a thread about this https://forum.xda-developers.com/u11/help/home-button-fingerprint-sensor-stopped-t3632297 this is no hallucination, I experienced it myself, and also a lot of One Plus 5, LG G5 and G6 owners. Seems to be a hardware implementation issue. Maybe same FP scanner manufacturer ?
Hey all,
I experience problems with the fingerprint sensor. It often doesn't recognize my finger on the first try but I need to try it several times before my finger is recognized. Or face unlock solves the issue and thus the finger print problem is avoided. I also deleted the finger print and set it up new several times but the problem persists.
Anybody else got the same problem?

Nope, my fingerprint sensor works perfectly fine.
Yours may be defective.
Take off the case from the phone. Make sure u scan ur finger correct.
If is not helping factory reset.
If is not helping call oneplus...open return due defective hardware
This finger print sensor reads much differently than what I am used to. For me it's literally a quick tap with my finger. If I hold like I would with Nexus 6p it won't read.

The sensor is really quite small and not perfect. I scanned the same finger three times (different parts of the tip) and now it works quite well. You will get occasional errors stating that the same finger has been scanned already, but if you keep trying it works
It's not a perfect sensor or even close, I've had to add a finger twice to get it to unlock properly most of the time. I add it as a new finger.

I bought the OnePlus 6 and I came from the OnePlus 3 and I ran into a similar issue. It helps if you input your fingerprint multiple times
For me its not that it doesn't recognize the finger, but sometimes it just doesn't even recognize that I have placed my finger on the sensor to check if it's mine. I have no idea why this happens
Mine works great. Sometimes I think it's even too sensitive, I turn the phone off and it comes back on when my finger is still in the vicinity of the sensor. Try to wipe it off with some mild water-dishwasher solution to get any dust/body oils off of it.

Are you running a custom kernel? I had this issue on Stock OS using Flash Kernel. Reflashing back to stock fixed it for me
My fingerprint recognition was always failing. The sensor was working because it would vibrate whenever I put my finger on the sensor but it never recognized it. I contacted OnePlus Support and the first thing they recommended is to see if there was an upgrade available. There was one - so I upgraded - not really thinking it would help at all. But miraculously, after the upgrade, fingerprint recognition works like a champ.
Try upgrading.

For me I had this same issue but not initially. The first 4 days I ran into zero issues. It worked every time. I then decided to start tinkering and installed the XXX mod. It wasn't quite what I was looking for so I decided to return to stock. At this point I flashed the stock rom via phone update menu. Then I factory reset and set up again. I noticed memory management issues and also problems with my fingerprint reader not recognizing my finger as easily. Re doing them didn't help. So I thought maybe I would use the fastboot method of restoring the software like the Nexus/Pixel roms. I did that and it flashed successfully but had the same issues. So I decided to manually flash each partition on both slots. Then I set up again. Still had issues. I figured at this point it was definitely a hardware issue because I felt I couldn't be any closer to a stock, out of the factory condition. But I was wrong. The msm tool that uses the Qualcomm drivers is the "Factory Image" I was looking for. It completely restored my phone to the condition it was when I unboxed it. I know logically there shouldn't be a difference but it flashed or fixed something on a certain partition that got changed when I was tinkering(I assume). So long story short. Try the msm tool if you think you have hardware issues before you rule out the software.
Fix-Fingerprint sensor not responsive
Entered to safe mode fixed the issue for me after a lot of trying to make it responsive.
Go into battery /battery optimization /hit the... Menu (advanced optimization) uncheck advanced optimization.
If on she is saving battery in sleep mode.
The issue you guys are describing is simular on rear sensors.
I did the above and it helped. Give it a try.
I'm having this problem with my NEW mi note 10 phone.
I notice it when first when I'm typing on my keyboard as usual speed.
It kept doing this phantom swipe across two finger taps.
I posted some videos to illustrate my problem.
Is it a software or hardware problem? (This problem is intermittent as well so it's really hard to pinpoint it)

ttps://drive.google.com/file/d/1-6M1e33Qxz8HXckkcLb3sWVTXG6fPHzv/view?usp=sharing (Using touchscreen tester, you can clearly see the phantom swipe across the two taps)
Anyone else having this problem except for me?
When this problem comes, I can't even properly play a game.
reformat factory reset - fail
reinstall latest miui global 11.1. 2 - fail
optimise animation all off - fail
gboard - fail
xiaomi keyboard - fail
SwiftKey - fail
turn off Miui optimization - fail
restart phone - fail
clear ram, clear cache, clear recent, speed boast - fail
CPU slowing down due to background processes?
Touch digitalizer got problem? (I tried shaking it gently, poking it but it does not affect anything at all)
As I said, this problem is intermittent. There are times when I can use it without any problems at all.
It's really weird.
It can be totally fine one moment and then it acts up again.
There's another thread about this. Most of us face this issue on all variants of the phone (Pro/Lite). This started with April or May update where Mi added a edge sensitivity control setting.
What happens here is that touch sensitivity suddenly reduces and it will be hard to do anything that involves rapid touch such as typing.
Lock and unlocking the screen or restarting the phone will fix this temporarily. There's no permanent solution.
Also when this issue occurs again, go to the settings and turn on Game Turbo for an app such as WhatsApp, without and then try typing on WhatsApp, you will see that the issue is gone.
We all are waiting for Mi to fix this. But I would advice to return the phone if it's under warranty though this is a software issue
