I have been using my Xperia z for about a year and everything was great until recently I have experienced weird problems. Now my power button is not working I can't lock my phone and I have to wait for screen to sleep. Now the weirdest problem is that when I wake up the screen (by pressing the volume button) the display is not responding at all just like it appears that touch screen has been disabled. When I reset my phone it all got to normal but then again if the screen went to sleep than it will never be responding and I have to reset my phone again and try not to lock the screen.
Help What is wrong with my Xperia??
Have you tried to repair the phone software with the Sony PC companion ? Click Start the "Support Zone", then click on the start button for "Phone / Tablet Software Update" then click on the blue line that says "repair my phone / tablet" and follow the instructions. Hope this helps. :good:

I'm having the weirdest problem.
My Xperia Z wont boot up, it will only boot when i have USB in my PC and connected to the Xperia Z.
When I disconnect the USB the phone shuts down in about 3-15 seconds.
I tried to reflash the stock tft via Flashtool.
I tried to reflash via SUS
I tried to reflash/repair via PC Companion.
At the moment stock firmware is installed but the problem is still there.
I tried to Google but I cant find anyone with the same problem.
Please help!
What's your battery like because to me is sound like a battery problem, USB is supplying power and a soon as you remove power it dies,
Boot phone up and do a service test on battery *#*#service#*#*
A maybe completely wrong
P. S. Have you had your phone near water what colour is the paper under your tabs (should be white not pink)

I have the exact same problem! have you found a solution yet? i'm thinking it's a hardware problem because of the fact that i have had this problem on different ROMs and even when i flashed it back to original firmware using sony's flastool.
The battery test under *#*#service#*#* says there's nothing wrong with it...
It's getting really frustrating actually... Phone is practically unuseable...
i think your phone does not turns off, im having the exact same problem, try put the screen to sleep every 30 minutes, if it last 30 minutes with the screen on, then your phone is having the same problem i have:
something like the volume up button "always pressed" so the power button doesnt react because its like detecting hard reset combination.
if the screen sleeps, you press the power button it does not come up, if you connect the usb, screen comes up. phone is not off.
if its like that, im glad i helped at least identify the problem (if you find a solution other than sending to sony (they'll charge me because my warranty is void) PLEASE TELL ME
EDIT: I FIXED IT!!

Hi guys,
I recently got my Xperia Z back from repair. I had it in because when I pressed the power button to unlock it, sometimes the screen would stay black and I wouldn't be able to see anything, but I could still use the touchscreen.
So I got my phone back with a new LCD screen and it's been a week now and it hasn't had that problem at all, but I'm having another problem.
My phone is randomly controlling itself. When I unlock it, every once and a while it starts pressing all the buttons on the screen. Opening up the task manager, swiping left and right, opening up the camera, etc. Just going completely haywire.
So to fix it, I tried a factory reset, but that didn't work. Then I got a new update for android, and for about a day it worked perfectly but now it's back at it again and controlling itself, pressing all the buttons etc. I had an alarm set this morning and I couldn't even turn it off because of it.
It's completely stock, I haven't even tried flashing or rooting or anything like that, and I'm running Android 4.4.4. Model number is C6603.
Anyone know what could be causing the problem?

there is some issue with touch calibration or some issue with the digitizer.

Well it happens before I even touch anything on the screen, so would that point to the problem being the digitizer?
Hello developers!
Having troubles with my Z's screen. Going to explain whole procedure.
After turning device on I can normally use it, everything works problem starts when I press power button to
standby, I cant turn it on but if somebody calls me, display goes on again. I can also normally use power button to switch off so
button is working properly. P.S. If xperia is on the cable, it's also working normally. Is it software problem or what? Have no idea.
Hi everyone I've got a big problem with my wife's Mi 5. After some minutes/hours of usage the touchscreen stops working and the only solution the make it work again is to reboot the phone (by keeping the power off button pressed).
I've tried some rom (MIUI stable, MIUI dev, Paranoid Android 7.3.0) but all of them have the same problem, someone has got the same issue?
I think it's not only an hardware problem because the touchscreen works most of the time... Any ideas?
I'm having the exact same problem with my wife's Mi5 too. I thought she was talking rubbish until I started using the phone full time over the past few weeks.
Symptoms:
Screen switches on and accepts one touch event.
Screen is then unresponsive to touch events.
All other buttons (home, power, volume) all work OK.
All functions work OK (calling, SMS, etc) via remote control (MyPhoneExplorer)
Screen then becomes responsive again after reboot
Tried so far:
Clearing dalvik/cache
Clean flash - using MiFlash and China dev ROM
Opened phone, cleaned all ZIF connections and reconnected.
It almost feels like something in the touch firmware or driver crashes and does not reconnect - as the phone is clearly usable save for the touch panel.
I'm going to ask Bruno/bgcngm and see if there's anything I can do to try and diagnose the issue.

In my case unresponsive screen to touch events, all phisical button works and the only option to make it works again is to reboot. I didn't try to use it with some "remote" control.

I didn't try to open the phone, but I installed all roms with TWRP and format data/wipe cache/dalvik before.

I also think that it's related with a software issue...

Well on my old mi4c i had similar problem. I mean sometimes when i pressed power button and tried to unlock it screen didn't work. For me solution was simply to press power button again to turn off screen and then turn IT on. Maybe this will help u. Have u try that ?

Do you think it's something related with Doze or standby? I think so because today (and yesterday and so on...) I wasn't able to turn off the wake up alarm (the phone was in standby with the screen off all night) with "the screen" but I have to force restart the phone with the button... and it's very annoying.
Maybe we can try with some Marshmallow ROM instead Nougat one.

I'm facing same issue.I've changed my display panels but it doesn't solve my problem.it is quite painfull.i don't know what should i do.
any update sir?
My MI 5 has a different issue. There is no response if I place the phone on the table, but it is fine if I held it. It seems the touch panel is only responsive when the sort of sensors that a human is holding the phone. I have no idea why it starts to happen in these weeks. This symptom happens even in TWRP, so I don't think it is related some particular ROM. Tried firmware 7.7.6 ~ 7.9.22 with no luck.
skip lock screen
Hi
I know I am late to the party, but just faced the same issue yesterday. To bypass the issue, follow the following steps
1. Restart your phone .
2. Enable developer options from about section in settings. (google enable developer options for specifics)
3. In developer options, there is an option to skip screen lock. Enable that.
4. Voila!!
Hope it will help other mi5 users..
Hi,
I had the same problem. I found this video and I tried to fix it. It worked pretty well. Bye
In a situation that I can't do any service for my Mi5 as of now - is this really loose cable thing ?
Can more folks confirm that this cable solution from above video works ?
exactly same symtoms :
Random screen freeze - only option is to reboot phone or phone goes rebooting randomly itself.

Connect to pc to back your data up. Also does the touchscreen work? And did you drop your phone or something else?
the touchscreen doesn't work
debugging mode is not activated, I cannot transfer my data to the pc.
I had the touchscreen bug for some time and suddenly, the screen did not turn on. The phone did not fall.

If it still under warranty i would send it to where you bought it. Even if you dont have warranty try it because the device should not be broken under normal use.
keep pressing the power button and when your phone vibrates try and hit restart. i know your screen is blacked out but if possible just try and locate. it happened with me too and thankfully my devices' screen recovered. the pop up comes just adjacent to the power button. first option will be your power off and then just below will be your restart.
I already tried
the phone reboots well but still black screen
