System Unresponsive with 5.1 Stock Rooted

Anyone having the same issue and have found a solution?
Phone suddenly stuck at some instances even with non-extensive usage.
Yesterday I was only using Facebook app. When messenger bubble pop up, my phone suddenly spiked. Moved once and then it got stuck already. You'll notice that it's not Facebook app only that's not functioning since nav. buttons are also stuck. You can't go press home and clear recent apps/hibernate apps. Power and volume buttons are also not functional.
So I assume the main system crashed. I only did a long press on power button to restart.
I installed Franco kernel r73, and thought that issue would only occur with stock kernel.
However, it occurred again today, I was viewing photos in Stock Photos app. I haven't started viewing the first 10 images yet, so memory should not be consuming that much. I turned on the auto rotate to view the image larger. When I turned the phone landscape, it reacted like it's about to rotate. And suddenly it got stuck. This time, power button is functional. It turns the screen on and off but it still turns to the same stuck screen, not the lock screen.
I've been experiencing this since 5.0.1. and almost everyday since I updated to 5.1.
I'm not sure if this is a hardware issue on my unit since mine is already about 1 year and a half old. I don't want to buy another phone yet!
Or is this a common issue nowadays due to Lollipop upgrade. If so, then could you provide temporary fix before they update this on 5.1.1.
Thanks a lot!

I had something similar . When I put forward the curtain hangs notice and then everything worked fine

Meh

I've seen this behavior on my Nexus 5 only on 5.1, and I'm pretty sure, it was introduced with that specific lollibug version. It's really annoying, that you have to reboot the phone every two or three days to avoid the freezes.
There's already in issue for that, it has got the ID 161032.

Touch screen sensitivity

Hello. I have an Nvidia Shield tablet k1 on lollipop 5.1.1. Everything is great about this tablet except the touch screen. It is really sensitive. Also, when I am scrolling, it "jumps" and goes faster than I actually scrolled. It scrolls faster than it should. I found this thread on xda. It helped a little with the being too sensitive issue, but scrolling is still really weird. This is my second device since the first one's micro sd card was defective. They both are like this. Is there anything I can do, or do I just have to deal with it?

I was opening a thread with this exact same issue. I'm not on stock though (using the latest CM12 nightly), so I don't seem to have the 'Sensor Calibration' option.
Also the touchscreen seems to register a touch even when the finger is not touching the screen.
On the other hand, if I scroll a very small distance (like 0.5 centimetres) the list I'm scrolling doesn't move at all. This doesn't happen on other devices such as my Nexus 5 and Nexus 7 and is very annoying in some cases (some games, or moving the cursor for keyboard input).
I'll try to record a video of this behaviour.
What can we do to fix this?
Update: found a video (not mine) showing the issue I'm talking about: https://www.youtube.com/watch?v=08uPtusOJHQ

anyone else with this issue?

I also have this issue on/off sporadically on stock rom.
I'll be scrolling and itll jump back the opposite direction
Its like it looses track of the touch then catches it again.
It's irritating as my S5, Nexus 2012 have no problems scrolling smoothly.
I don't recall the original shield i tested in store to have this issue either.
Currently having amazon ship me a replacement to see if its just limited to the one I received. (QA issues)

Calibrating screen might fix the issues: go to About in settings and tap on model number until the calibration screen comes up. then hit calibrate. don't touch the screen then when it asks to reboot, reboot.

Did it fix the issue I posted the video about? I'm on Cyanogenmod now so I don't have the option to calibrate the screen, but I would consider going back to stock if it fixed this issue...

Calibration doesnt help at all , same issue at brand new k1. Nvidia says thats normal functionality lol

Yeah, very normal for a gaming tablet which would require precision...

Not trying to take up for this thing but I haven't had the first touch screen issue with it . so maybe not all is affected?? I've tried to replicate the issue but just can't everywhere I touch and slide is smooth

You mean it doesn't "jump" like the OP said? I don't seem to have that issue either.
I'm more concerned about the touchscreen's precision, as shown in the video.

Question about touch sensitivity

I bought an XT1540 as a birthday gift for my wife and she is having an issue with apps and other things opening when she scrolls. It may be on Facebook, in Hay Day or whatever. I ran through several apps on it and did some of the same things she was doing. I didn't have any problems at all. So maybe it is a matter of how a person scrolls or touches when navigating. However, I now have a very unhappy wife who is ready to throw the phone across the room half the time because it keeps opening stuff when she scrolls. And convincing her that it is her and not the phone is not an option. Tried that and she went to work angry at me.
Any suggestions? Does the Touch and Hold Delay help? She is on stock 6.0 and her phone is an XT-1540.
One final thought, is it possible that residue on her fingers from makeup, hair gel or some other product she uses may be affecting how sensitive her touch is? Just a thought because that is the only thing I can come up with that is different between her and I.

There have been issues with newer touchscreen firmware on some devices (including mine). With the 6.0.1 firmware, my device gets super sensitive and frequently registers swipes as a tap then swipe. The solution is to roll back the touchscreen firmware to the Lollipop version, though you need root access to do so. If her device is rooted and running a custom recovery, you can try flashing the "L_Mretus_synaptics.zip" from here: http://forum.xda-developers.com/showpost.php?p=66002023&postcount=1262

Tablet doesn't recognize all of my touches

Hi, i've been using the NVIDIA SHIELD K1 since january, and one thing that has always bothered me is that it doesn't recognize my fingers when i tap repeatedly, i play these rhythm games that requiere two or more fingers on screen, and losing because of the tablet not recognizing my fingers is painful, i tried rebooting and a number of stuff i thought could work, but there's no results, it even stops recognizing while i'm holding my finger (moving an app's location, for example).
This wasn't a thing in my previous one, it responded instantly with no stutters regardless of how many fingers i had on the screen, so i don't know what to do.
It's rooted with TWRP, i haven't used any ROM's as i don't feel like i requiere any, settings are always on max performance and i kill all apps that i leave and won't use so everything runs smoother, i also disconnect from internet when playing but it doesn't seem to do anything, can anybody help me with this?

Try doing a screen calibration; that worked for me.

I've tried screen calibrating, but that didn't work. Currently android 7.0 seems to make this less frequent.

Screen calibration worked here too, K1 tablet.
I accidentally found out about it yesterday btw haha

All issues Android 10 update xz2 compact

I think it would be useful to have a collection of all bugs of the android 10 update. From my point of view it is a disaster.
I noticed the following (after I factory reset it) :
Touch issues - touching the screen lightly does nothing. I have the actually tap it... This makes writing a pain, as hard to reach keys do not always register
Backlight auto adjustment issues - now it's very aggressive and basically stupid. I'm sitting in home, in the evening, almost without moving, definetly in the same spot and the backlight just jumps around in big increments
Lag and shutter in daily usage - a restart solves this for a couple of hours...
apps are now often reloaded - memory manager is too agresive and kills background apps
GPS NOT WORKING. It was flawless before update ?
build-in swiftKey keyboard does NOT remember how and where you type IF you change the keyboard layout /position (compact, split, side, etc...). This essentially makes it useless

A factory reset is not enough , try software repair using Sony companion

Im not having touch or GPS issues, but my phone is definitely slower and laggier since the upgrade to android 10. ALso my battery seems to be depleting faster. Is there any way to roll back to 9?

Wifi is often lost and quickly reconnects
fingerprint sensor isn´t as sensitive as it was before
battery drain is bigger than before
bluetooth pairing with tablet doesn´t work properly...being paired: YES, but no connection at all...tried three different tablets...bluetooth headphones work!

The camera application is crashing when I take photos.... :crying:

I really haven't faced any of those issues. The fingerprint is the only things that have become laggy, the phone is louder now when playing music, camera works great even with unlocked bootloader.
You should try to do a clean install with newflasher my phone is even rooted and works great.

Scratch that... I am experiencing all the issues from OP's post. It is especially severe when trying to use two apps at the same time in split screen.

Sony mobile engineers answer my bug report
Android Beam doesn't work (transferring files by touching two phones with NFC).
Nothing works on this phone any more!
I will never buy another Sony phone and surely I will advice others against buying such sh*t.
------------------
I contacted the Sony support in my country and they said "the download must have been corrupt" and I "should try to reinstall" via the Xperia companion (some kind of desktop app).
Mind boggling is the fact that this answer comes "directly from Sony engineers".
Now... I guess it is clear for everyone why they f*ucked this phone so bad. Their engineers think that a corrupt file can 1) be installed successfully 2) cause all these bugs...

Why factory reset is not enough?
If the corect procedure is to use that "companion", WHY they pushed the update via OTA?

The only brand who has this crappy issue is Sony ! Companion fills all the missing files or damaged files .. during the ota download and installation sometimes things go wrong

For everyone reading this thread: there is no such thing as instalation with corrupt or missing files.
All files in today's IT world are uniquely identified and double checked after download.
Their answear is only a way of not telling us that they f*cked up this + they think that we are stupid. Some of us might be fooled by this, but surely the majority won't be.

We have primarily the camera issue, a reboot resolves it temporarily.
Anyone managed to fix these issues with a fresh Sony companion install?

52.1.A.0.618 here. Fingerprint is slower and the battery drains faster while screen on. (Standby and deep sleep are both ok). Everything else is the same as Pie, at least for me.

Add me to list of unhappy xz2 compact owners. Phone is almost unusable since the update. More often than not the finger scanner only works when you press the power button first, it lags awfully in most apps, I get errors in apps I never did before, battery drain is about the same as previous. Overall this is my last Sony. Very very poor. Should add I did full companion restore and it made zero difference

I have to add my voice to this thread, short as it happily/sadly is. Since the update I've experienced a number of issues: Fingerprint scanner is less sensitive and sometimes doesn't work, the wake-up procedure is strange, in that the icons will appear before the background loads and even though I have security set to not show notification details on the lock screen, they'll reveal for a split second before waking up to the home screen, the camera is unreliable, the timer app doesn't reset or dismiss when appearing on the notification bar..
It's the first time I've ever emailed Sony Support on what was (and I hope still will be) my favourite ever phone. They of course just tell me to factory reset. Such a shame and I hope they fix it.

I'm having the same issue. Not sure what is wrong. I have not factory restored my phone. That is ridiculous

I also add the bug of Google Assistant in Stamina Mode:
I always keep It disabled when long press home button, but when Stamina Mode turns on, Google Assistant switches on again automatically although in settings shows that is off.

wow its been 2 years since I bought the XZ2C, had issues with the wifi and data so I went back to android 8.0, and use it for O2 priority only. Came back to see if android 10 fixed the problems. Disappointing.
I am not surprised at all that Sony still hasn't fixed any of the issues.

With today's New Update the the voicemail-Record-Volume Bug is fixed.
Finally. Too good to bei true.

there are still a lot of vital features that were bugged in android10 and i´m not sure they´ll be adressed in the near future.
