I've noticed in the last month or so that my VS985 cameras are not working. Launching the camera app just shows a black display with the "back" button. I was rooted but reverted back, I bought the phone in December, rooted in January and had no issues until more recently. I took the following steps to troubleshoot:
1) Try "Google Camera" as opposed to stock app
2) Unroot
3) Verizon SUA to 24B
4) Disassemble and reseat connections
None of those steps have proven any good. I'm not sure whether this is a hardware issue or a software issue at this point. Would both cameras just happen to die at the same exact time? Or, could this be something deeper than the OS?
On a side note, has anyone else had issues with the SIM card randomly not being recognized, warranting battery and SIM removal? Thanks for the help everybody!
Hi,
My Z4 just asked to update the ROM, and afterwards, the screen has areas that are no longer touch sensitive.
Is anyone else experiencing this issue?
Thanks for any ideas!

Have you tried rebooting, then opening the Diagnostics app and running the touch screen test? If there are still dead spots showing in the test, you might want to flag it to Sony support.
I'm not certain if it's a software or hardware issue, but I have found both pre and post-update, that the touchscreen occasionally becomes less responsive, to the point that trying to use a drag gesture doesn't work without the touch dropping out. This happens every couple of days, and I suspect it's to do with throttling as it coincides with very sluggish performance. Seems to resolve itself when left for a few minutes, or a reboot.
Yes! I thought it was just me. I have a tempered glass screen protector and removed it to confirm whether it was causing the issues. Also ran the diagnostics which ran just fine.
It seems to be perfectly fine after a reboot and then the longer you go the worse it gets.
Hoping that this is fixed in the 5.1.1 update whenever that happens.
The conditions that this occurs does seem extremely sporadic. After playing Star Wars Uprising for ~45 minutes yesterday morning, the touch screen failed to recognise any swipes or taps, to the point I had to force a restart with the power button to exit the game. After leaving the Z4 for 15 minutes, no issues at all.
Last night I managed to play the same game for over 90 minutes, and today for another 90 minutes with no problems at all.
I'm starting to think that it could be performance throttling, alternatively I have noticed the screen getting particularly warm above where the SOC sits. Could this temperature be affecting the screen sensitivity? Using CPU-Z I have found some of the sensors reporting around 70C, battery around 35C, though this is after running intensive games. I'm unsure if the upper temperature is normal for this type of chip or not.

I have the very same problem:
Tempered glass from IVSO and the original case from Sony.
Since the update the touchscreen is VERY unresponsive.
I removed the case (!) and it got better (seriously, WTF?).
Does it mean to remove the tempered glass will solve the problem?
But it was fine before upgrade to 251. Sony sucks...

I reset to factory settings, and that may have cleared it up... but I'm not positive.
I'll update this thread when I play with it some more.
Did anyone have success with removing the screen protector?
OK - I can confirm that a factory reset after the upgrade does not solve the problem. My tablet cannot pass the touch screen diagnostic.

I removed the case, not the screen protector.
But some issues are left, so i hope for the next FW-Update...
An update:
I reached out to Sony's support group. They suggested downloading the PC companion app and having it reflash the .251. This does a factory reset.
This made the touchscreen response significantly worse.
My next step is to see if they will let me downgrade to the previous release, because the tablet was working flawlessly on that release.
Sony support says you can't downgrade to the previous rom. I found flashtool, but can't find the old rom to flash onto the tablet. Still looking...
Noticed the same thing after the update.. Hoping for a fix soon as it was flawless before the update.
Now simply browsing is annoying because it either misses swipes or registers them as longer swipes, causing the page I'm trying to read to scroll down super fast as if I flicked it when I actually scrolled slowly. :crying:
There is no update coming. Sony does not acknowledge that the problem exists.
Need more people to post on Sony offical forum, tell them this problem.
I'm hoping the .253 version helps this problem. It doesn't appear to be available for anyone yet.

Here is a complete tutorial about flashing any firmware on your Z4 tablet, even downgrade to an older one.
http://www.xperiablog.net/2015/03/1...peria-lollipop-using-xperifirm-and-flashtool/
I flashed Nordic version of 28.0.A.7.24 firmware and my touchscreen sensitivity is back to normal
If you have any questions about the flashing procedure feel free to ask.
I had this exact problem after updating to 224. Ran the Sony Pc companion program on my windows pc and did a full software restore on my z4. problem solved.

I'm not sure whether is it because of root or Xposed, but after doing a factory reset, the touchscreen seems a bit more responsive. It is after rooting or installing xposed that the problem comes back up.

Ah, I also have intermittent touch problems. Until now I kept thinking it's because my finger is too cold or something, but I have it since upgrading to .224 also. Rooted and running Xposed v.85.1.

Yea, I kinda think it's either because of root or Xposed that's interfering with the touch sensors. But I'm kinda leaning onto to Xposed that's causing the problem.
So i bought the phone yesterday,i opened it and did the casual setup including setting up 10 times my finger on the scanner.
So by the time the phone was setted for first time there were official software updates poping and i clicked them to download and install...after the updates were done i found out that fingerprint sensor settings were missing (both lock screen and fingerprint & security section) so i did a factory reset hoping it was just a minor issue...After the factory reset the options were still missing...i got 5 days left to return the phone if there are problems and i want to know if anybody knows
1.is the problem software related and i just need to wait for official update to get fixed?(i heard december lg launches official nougat version for the G5)
2.is it hardware problem so i take the phone back for repair?(power button works perfectly)
i really loved the phone so far especially the camera and everything and i really want to enjoy it (my prev phone had a lot of software bugs and i never actually enjoyed full of it...)
anyone know any fixes?i dont want to get into custom rom again (i really like the lg ui for change) if its software problem
Thank you for your time!
i guess no one has the same problem and my device is faulty?
I would try and exchange it because I don't have this problem and if a factory reset didn't fix it it's probably a hardware issue.

my bad people,it was NOT LG's problem,hardware AND software are perfect,its my first phone with scanner and i found out the hard way that to add fingerprint i HAVE to add a pin or a different unlock method before adding figners....sadly i rooted my device firstly to add cyanogemod and then i found out...so now i lost my warranty i guess...but at least now i know and if anyone else finds the same ""problem"" this thread will help him
Lesson learned for you. Why install a custom ROM right out from the start? Based on my experienced with my G5. It's performance is great. All things are great. I'm fine even if my phone is not rooted nor can't install a custom ROM. Unlike my G2. But by so far the phone is running great. So enjoy first the things on stock firmware.

i didnt want to install custom rom as i already had in my prev device (oneplus x) and i always likes lgs skin on android
but i wanted to see if the problem was software issue that cyanogen could fix in this case...i wanted lgs support to be my last resort as their services are bad,they tend to take week(s) to fix the phone and i heard from people that their phone returned scratched (that lg supported claimed they didnt do it)...so yeah i prefered to install custom rom and risk that i have to live without fingerprint than send the phone and get it back deleayed and probably in scratched condition
lesson learned indeed
So I broke my screen a few weeks ago and had a brand new screen replacement sent in. This is my 2nd screen replacement on this phone so I know how to disassemble and reassemble the display.
However when I reconnected the display, I turn on my phone and I just get a black screen (while the LCD is powered). It will boot into Android as I can hear my messages coming in. The bottom screen navigation buttons also turn on.
If I peek under the screen it looks like the back light flashes on and off a few times before staying off.
I would love some help on this issue. Any information is welcomed. Thanks.
Heyyo, tbh I was helping a user with the same issue and after trying many things even QFIL? The problem was the replacement screen is defective. He could swap back the old display and it worked (albeit it was cracked) and the new display only the backlight would power on but fail to display anything.
I'd recommend returning that replacement screen as soon as possible and get another screen.

Hey, thanks for the advice. I tried the qfil thing and it seems to have a display now but half of the screen is on the left and half of the screen is on the right.
Heyyo, cool! That's lucky in your case that QFIL actually got the display working.
Ok, to fix the split-screen display issue? You must next flash the official build of EUI ROM 14s. It can be found in this thread:
https://forum.xda-developers.com/le-max-2/how-to/le-max-2-official-stock-firmware-links-t3433761
Afterwards? I'd recommend flashing a newer EUI ROM once your display is fixed, something like 19s or higher before formatting data and wiping your device and switching back to a custom ROM.
Awesome, I will try out 14s and report back. I tried 16s, 20s, and 26s which all seemed to fail. Hope this will do the trick!
I've been trying to guess what the actual issue is and I'm so happy it's not hardware related to the connector or something like that. Just a guess but was it software driver related? Is it possible this screen replacement is from the 1st gen of screens that went out and that's why it requires 14s where as newer screen replacements possibly use 16+ and up? In any case, this issue seems pretty rare to x820 users.
Where did you buy the screen? Under normal circumstances, there are practices to try on the machine, do not be too anxious to install, test if there is a problem to take a video or take photos to the seller's customer service staff to solve, in most cases in China, and many of the screen is not original, The best is to disassemble the machine, hope to help you：D：D

Hey, I flashed 14s and the flash worked but I still have the screen cut in half with the left side of the screen on the right side and visa versa.
I had to flash with "Zip Flasher" tool since the touch digitizer doesn't work in TWRP with the screen swapped as it is. Any other ideas?

I used "Direct link to 14s Chinese ROM" but unfortunately the same issue. Any ideas?
Heyyo @quatchis, hmm unfortunately the QFIL then wipe everything and format data then flash 14s is the only fix that I know of... I'll try to ask around if anyone knows of another fix for split screen bug...

Thanks for the help. Yeah, I tried the QFIL then flashing 14s while wiping all the data/dalvak/cache. Also tried multiple successions using TWRP 3.0.2, 3.3.1 and TWRP 5.8 TeaMSpaiN.
I'm thinking I might just toss the phone at this point since I've bought 2 new screens both which didn't work. I don't think its worth more investment which is hard for me to say. I even had bloody Linux booted up on this bad boy at one point.
This was my favorite phone I have ever purchased and it was worth every last penny. Do you know of any new snapdragon phones that will give me 3 great years of performance. I was even considering a new LeEco phone but have not done any research outside of the LeMax x829.
Heyyo, If my x2 were to die and same with my nash? tbh I'd recommend looking at anything Xiaomi related or other flagship killers like the stuff RealMe have as well. They offer the best price to performance and they are great for kernel source releases and custom ROM communities. I know on Black Friday/Cyber Mondays there was some great deals on stuff like the Poco F1... But meow? Tbh I'm unsure what kind of deals are out there sorry...
Otherwise? There are other brands out there that offer great devices for darn cheap.
For TWRP though? I'd recommend either the latest official (and ignore the failed to mount vendor errors in logs since vendor partition only gets created on treble ROMs) or TWRP official 3.1.0-0. I wouldn't bother with the other TWRP builds.
But just to check, after QFIL it should be...
reboot to fastboot
fastboot flash twrp-3.3.1-0-x2.img
fastboot boot twrp-3.3.1-0-x2.img
Wipe > dalvik, cache, system
Wipe > "format data" button > type "yes" > keyboard checkbox
reboot to recovery
Copy EUI ROM 14s to device
Install EUI ROM 14s
Reboot to system
Hello. I've heard that the Chinese (OnePlus Ace 2) version of 11R has some issues after flashing from Color OS to Oxygen, like not working fingerprint, not working OTA update (if you update, you get a bootloop), issues with notifications, etc. I have ordered one from china and I am a bit worried. Can anyone confirm this?
Mine is from china and it is oxygen now. I only experience issue that sometimes when I turn on the screen it will flash rapidly for a couple seconds.

Update: Also experiencing occasional screen flash during unlock, turning auto brightness off lessens it but it still occurs.

I ordered one from china too.They also changed from color os to oxygen os.Now I'm facing the same issue as you.The issue doesn't happen every time tho like when I open the phone and it will start to flicker for a sec and then the screen goes dark for a sec and returns to a normal state.I'm just concerned that the issue will damage to OLED somehow.I'm also experiencing regional sim problem.Eveytime I reboot my phone, the warning note shows up (you're using region-cutomized phone......) and it kinda annoying even tho I can make phone calls and use internet as yet.
I got mine yesterday, but many issues occur, flashing screen, autobrightness does not work at all, alwasy-on display causes flickering, random reboot (not often, once or twice a day i believe) and the biggest problem is the region lock, although seller told me three times it was unlocked...
Do these issues occur with color os too, can anyone give some feedback please?

Thought I was the only one. I do have the exact same issues as you.I can use only 1 sim (for internet only) ,I can't make phone calls to anyone but recently my mum calls me twice somehow but now when I try with my mum phone to call my phone, it's not working tho.I believe these happens except region lock issue because of oxygen os.Though I never told to change to the oxygen os, they already changed it.Even Redmi phones don't have like these issues.I instantly regret buying it now
Yeah, i am thinking of returning it, selling is not very clever... So you think these issues occur cause of region lock? Or every china model flashed with oxygen os? I believe some parts of system must be taken from color os, they dont get flashed, and that can cause incompability... Mine stopped making calls after i rebooted few times.

If you have a problem with region lock, send me the imei number 1, and I will send you the code to cancel it for free
I did hardware test, and the lighting sensor does not work properly, or at all, it is detected but it does not register changes, it is overall with readings. Seems like driver issue or incompability, i suppose if we used the driver from color os it would work, but who can change that?
