Stuck in safe mode on my Z3TC - Xperia Z3 Tablet Compact Q&A, Help & Troubleshooti

Hi,
I've had my Z3TC for around 5 years now and still love it but has been having a few issues recently, notably the battery life is getting worse, but it's still usable. However, yesterday, something strange happened to it. The power on/off button stopped working when I pressed it once (double press for camera still worked), so I couldn't turn it off or turn the screen off (other than my closing the case cover) and one of the volume buttons didn't work either.
Then, the battery dropped from around 40% to 0% and it shut down. I charged it overnight and this morning when I turned it on, all the buttons were working again but it was in safe mode. I tuned it off/on multiple times, restarted it, rebooted in safe mode then rebooted again hoping it would go to normal mode, but none of this work.
I've now done a full factory reset and it is still stuck in safe mode (and I've restarted it, turned on/off multiple times). Are there any suggestions for how I can get it back to normal?
Thanks,
Frank

Nearly the same thing happened to me. It happened about 3 years ago. The power button stopped working (just like you), so I chucked my Z3TC. To this day, it was - and is still one of the best - phones I ever had. I ALWAYS got asked questions about it. I own an iPhone now, but I still love the Z3TC. The camera was terrible, but everything else about the screen was solid. Just wished they updated the OS on it, but due to Google and the chip restrictions, never got far. Either way, I'll never forget this phone. Pity our time came to an end due to that power button breaking.

Also stuck
Same thing also happened to me.
I had the tablet for quite some time and the battery would start going straight to 0% from quite a high number. And also my volume down button doesn't work and I am stuck in safe mode. Rebooting, poweroff, etc doesn't make it get out of safe mode.

Had to get my phone replaced!

Had to get my one day old Nokia 800 replaced today.
Got everything setup last night and decided to power it off just to give it a restart. The phone would refuse to power back on. No amount of button pushing/reconnecting to the power would make it start up again. No power, nothing..dead.
I managed to get it to restart after performing the three button reset. No problem I thought maybe just a one off. Turned the phone off and put it on charge overnight and this morning the same problem returned.. Could not power on. This time the reset would not work at all, no matter how many times I tried.
Carphone warehouse swapped it over in store today for another handset. Hopefully I'll have more luck with the replacement.
Edit: already seen someone else mention a similar problem on here. Hope there's not a bigger issue.
How do you perform the three button reset? My phone randomly decided to turn off whilst I was driving and now it wont turn back on
Yes I've been in that spot as well. For five minutes the phone wouldn't respond to any power button press. Long, short, whatever. I was already starting to slide into panic mode when it suddenly came back alive on another short press.
It's not the only hardware problem I've encountered, I also have problems with touchscreen and buttons and a loose part inside the device.

Strange sleep issue after .13 update

So all seemed to be fine and dandy after the update, but I went to check something on my tablet and it wouldn't wake up. Pressing the power button, or even holding it didn't do anything; the screen was black. I held volume up and power and it vibrated, then I held it again and it vibrated again. The third time I did this, it finally booted up again.
Dunno what this means.
EDIT: Just happened again, although now I can't seem to get the thing back on. The screen is just off and vol. up + power only makes the thing vibrate after a few seconds. I simply left the prime on the lock screen and came back and it was stuck again.

Mine does the exact same thing when I tether it to my Sensation with BT.
I'm still on 2.11.1 though
UPDATE
I just manually updated my pad to .13 this morning. It did NOT alleviate my problem but it didn't make it any worse. Unlike many other user who report the lockups when sleep now, mine still only occurs when I tether BT and it goes to sleep. On the upside, I've tested my wifi and do confirm an improvement ~20% increase in signal strength and quality.
According to dd-wrt on my router signal increased from about ~49% to 63%
and Wifi analyzer signal strength ~77-68dB to ~54-47dB. I have not tested GPS.
Apparently the build variance between pads are reflected by the variance in the effects of the update

How do you get it back on? I can't seem to power it up now.
EDIT: Nevermind, I just held power and it turned back on after about 5-7 seconds. I think it might be a "Wifi off during sleep" issue..but idk.

same thing is happening to me after the update. My prime never used to do that but something in the update screwed with it. is there anyway we can revert back?
Doubt this is an update issue as I haven't seen it yet or most others. Or they all would be posting about it. That is strange though. You all didn't root n go messing around with stuff did you? Lol. If anything I'd try a fresh reboot. Maybe even clear out all the caches. Something else is seeming to cause this. By any chance did you install chrome beta? Some users reporting strange things since installing it. I don't think its the app but it is strange though or coincidence.

no I didn't root. I may factory reset if it keeps doing it and see if that works. I got a decent working prime and it would suck if this update is giving me problems. yes I did install chrome beta but this issue happened before I even installed it so that can't be it.
Ok, this has to do something with the update.
My perfectly fine from before prime wouldn't unlock. I couldn't get it to respond. (I thought it was dead..) I tried to unlock and pressed volume, did nothing.
I just read this thread and tried holding the power button and it vibrated and booted after the hold...
Asus needs to stop the patch roll out untill this is fixed...
Same problem for me. And after a short sleep, it wakes up, but there is a delay of about one half second that didn't used to be there.
-gary
After that one sleep, it has not yet repeated since last night for me
not only did mine do the same thing but it also killed my battery life while my Prime was sleeping... epic fail asus its time to return for a refund and never look back.
Maybe try reverting back and see if the problem goes away.
This hard-to-wake-up issue happened to me once after the update, but my Prime did finally wake up. Have not had the issue since. There was a lag in the wake up yesterday also, as others have mentioned, but even that seems to be gone now (or I'm just used to it).
Possible fixes for this situation:
1) Hard reset (stick an open small paper clip into the little hole just below the microSD) -- I'm sure most of you have tried this already...
And, if that doesn't work:
2) Hard reset, then reapply the .13 firmware update manually right after (assuming that is possible)
My tendency is to always do a hard reset just before any firmware updates -- makes me feel a little more confident. I was lazy and did not do that yesterday, but it won't happen again.
enough with this crap
Dude, you really gotta stop trolling, this is the third thread you are spewing this crap in in the last three I read.. You obviously are not returning it, you just like to *****.

unsure if this is the right thread, but mine's been acting up since the update as well. when i'm actively using it and turn off the screen, it boots up as quick as before to the unlock screen. however, after letting it sit for a few hours, it seems to have shut off where i'll have to hold the power button on for a few seconds (after 2 or 3 tries) to get it to boot up again as if i reset the tab.
Having the same issues with mine as well. I have installed Chrome Beta, but had it running for a few days pre-update without issue.
I almost always keep mine in the dock, but haven't had a chance to determine if it only happens in the dock or not.
i have seen this occur in the past ..before the update.. i thought the battery was dead but plugging in the charger didnt do much.. held the power+vol up 3 times finally woke up .. and said 36% battery left... i m on the verge of returning this after 2 weeks of use.. just cant get over these silly silly issues
Mine just did the same thing. I'm on the newest update. Had to hold power button 10+ seconds for it to come back.
Sent from my Transformer Prime TF201 using Tapatalk
Mine died over night with a charge of 36% in balanced mode. Had to hold the button down for 10 seconds to get it to turn on today after it was plugged in the charger for 20 minutes. Now when i wake it out of sleep there is a .5/1.5 second delay for the screen to come on.
Same issue
Had absolutely no issues with my tablet prior to this update - no random reboots, but now if it's off for a minute or more, I have to hold power in for 7-12 seconds to boot up the system.
Hey, just a thought.
Maybe also include the first few of your tablet's serial number to see if the problem is consistent with some batch(es) and not others? May help others that's going to update...

[Q] Samsung Galaxy S3 shuts off randomly. Won't turn on consistently?

My Samsung Galaxy SIII smart phone has only recently been having issues. My phone will turn on, will be charged and function as normal - ie, no performance issues at all when the phone is actually on. But sometimes, my phone will randomly shut off with no prompt or message. Sometimes it will attempt to turn back on itself, other times I need to press or even hold the power button to turn it on.
The real problem is when it boots, it SOMETIMES (3/5 times average) will begin to boot, then the screen goes black again - ie, the Samsung logo will show up upon vibrating, then shut off or reboot and try again (this can sometimes happen singularly or in tandem). Other times, it will boot as normal, sometimes working normally, other times just randomly doing the abrupt shut down, and the cycle starts over.
I've tried taking the battery out, rebooting it, booting to safe mode, removing battery + keeping it out for ~10 minutes to discharge, etc. My phone isn't up to date, as my phone is rooted. However, I haven't modified my phone or done anything to it in a long time, and this has only has begun happening recently. My current firmware is rooted stock Android 4.2. Are there any other solutions besides formatting my phone? I cannot send it in/get it replaced by my provider as my warranty has expired. Thank you. :angel:
Go to the Play Store and download emmc brickbug check.
Get that diagnosed.
If it's good i suggest you do a full wipe and update it to the latest samsung 4.3 update.
Ultimate GS3 sudden death thread.
Well you better get up to date, best to start with a factory reset and the latest stock rom first.
I guess you're running an unstable leaked 4.2.2 firmware,so I would suggest you to install stable 4.3 firmware.
Maybe your power button got stuck..
To find out, push your power button and keep hold it even the "samsung galaxy s III GT-I9300" appear.
Do you experience the same thing or not.

I found a fix for my S3 which was doing EXACTLY what many of you are describing. I will get to the fix and it will sound ridiculous, but it worked for me and for the other people responding to the posted fix. ***** Hint: my problem was the power button and the fix was free and easy though may require you to be pissed at your phone as I was at the time.
Before getting to what fixed my phone. It seems like every one with a Samsung phone Sh*tting out in this manner should go through the well-conceived sequence I post below in the link. That guy though through the problem and made a great help list even though I found myself with a phone that was a mess even after all of those steps. My phone just vibrated when I tried to start it or maybe it began to show a graphic screen of the boot process before it went to black again and just vibrated. I am stuck with 4 more months of verizon contract so I was desperate and unahppy to say the least. I tried at least 50 time to boot my phone yesterday and went to a verizon store they were no help as expected especially when they saw a boot screen image that they did not recognize... I was one of those rooting creeps that they are not obligated to help...
first link:
http://thedroidguy.com/2014/03/fix-galaxy-s3-wont-turn-troubleshooting-guide/
A stuck or malfunctioning power button can cause... getting random reboots, lack of starting, lack of posting, getting stuck at various screens in the boot process and then going to a black screen which may just accompany a vibrating phone or a seemingly dead phone. Our problem is the power button being "stuck" underneath/inside of the janky, crappy little clip on power button that you are actually pushing in on your phone.
see this youtube video. In other words the thing you push is only pushing something else inside. I took my power button out (it clips in) cleaned out the cavity by blowing and with a toothpick and I was fixed!
http://www.youtube.com/watch?v=pQ-U-Q_NdOo
I was pissed at my phone so where the guy in the above youtube video says something like tapping his nail (finger nail) into the power button or whatever I was pretty aggressive and crammed my thumbnail down the sides of the power button until the janky little piece of crap actually popped out revealing itself as a clip kind of a thing. I then blew the hell out of the hole with all of the breath I could muster and took a toothpick and depressed the actual power button several times and "cleaned out" and cleared out any hair or gunk (really did not see any) that might have been in the socket. I put my power button back in (just clips in by itself if you put it in the socket the right way and push down) and I have had NO PROBLEMS since. Start with the first link I posted but be wary of the clearing Cache part unless you no what you are doing ahead of time. I had just done a factory reset and total wipe with TWRP before installing a new ROM so I did not have anything to lose. You might... I don't know enough about what resides in "cache" to advise you. Then if you are still in trouble listen to the second post which is a video. I actually crammed my thumbnail down into the power button cavity on both the top and bottom (the long axis) of the button aggressively enough that the visible button popped out. Then I did my blowing and cleaning, etc... crammed the visible button back int - which clips into place and I have been stoked since. Hope it works for you if not, sorry!
*As a side note, I sort of assumed that the problem with my phone (and I bet yours) has something to do with power: either getting to the right place in the phone from the battery or the power chord OR the f*ing power button on our cheap, janky plastic yet expensive Samsung phones might be a problem because before the weird random reboots and not booting began the power off dialog (like when you hold the power button down long enough and you get the "reboot" "power down" "airplane mode" menu kept coming up while I was surfing watching youtube or even talking. I figured it was time to install another ROM, did so twice and still had the same issues. I reflashed recoveries back and forth from TWRP to the other one several times too. Nothing worked until I cleaned out the power button. Go figure.

I tried a similar approach and it looks like it actually worked. I just took the plastic cover of and removed he 10 little screws and played around with the plastic thingy that depresses the power button. I don't know what exactly fixed it but is seems to work.
So you might not have to remove your power button but instead just play around with it first and see if you can't get it to function properly again.
Thank you so much brjoon1021!
Galaxy SIII I9300 shuts of randomly but only when not used
I have a problem with my S3 since about a week now. First it was a standard S3 with stock ROM and not rooted. The phone would turn itself of 3 - 5 times during daytime and also at night when charging.
What I tried:
- Clearing battery connections
- Cleaning power button
But finally I think it's not a hardware problem. Loose contacts, battery connections or a power button problem would probably cause more shut downs when I was using it. But in my case it's the opposite: it always shuts down when I am *not* using it.
So I rooted the phone and flashed a custom ROM on it: [ROM] [4.4.4] [CyanogenMod] [GCC 4.8] [Excellent] [31/12/14] ArchiDroid V3.0.2
That was succesfull, but after that I still had the same problem.
When do I have this problem: as stated: always when I am *not* using the phone. It's lying on my desk or next to my bed, charging and no program is running.
When I don't have the problem: when some program is running on the foreground, at night during charging if I keep the clock on the foreground (daydreaming), when I have waze running (in my car) etc.
I have the impression the device only shuts itself down when in deep sleep mode.
I also tested if it was a case of Deep Sleep of Death, but when the phone is shut down, I can not text to it, the LED does not light up.
I can boot the phone by pressing the power button once for about 8 seconds, so that seems a normal boot and not a reboot.
Any suggestions on what I could test? Or how I can find out what the problem is?
Thanks!

Well it started to get worse every day, so we tried factory reset once more and after that, the phone just died. (only colored rubbish is shown on the screen) ...
Never ever buying Samsung again. Piece of crap ...
Anyway we had chance to buy LG G2 on the sale. I know it's quite old, but the price was perfect and it's many times better than S3. :good:

Two odd issues after T820XXU1ARA2 update (wi-fi, power button)

Purchased a Tab S3 from B&H in early January. It came with T820XXU1AQI2. Everything worked fine, absolutely no issues. When T820XXU1ARA2 was made available in early February, I allowed it to install. The install occurred without issue, and initially the tablet appeared fully functional. Now, two problems have manifested themselves.
#1. If the tablet is idle for several hours -- usually more than 18 or so -- wi-fi simply quits working. The tablet appears connected to wi-fi, but has lost its IP address and can't obtain one. Occasionally, simply switching wi-fi off and back on will sort things out, but not usually. Occasionally enabling and disabling airplane mode works, but not usually. Most times I need to reboot the device.
#2. The power switch becomes ineffective. This happened the first time today. I tried to wake the tablet from sleep, no response. I plugged in the charger, which woke the tablet up. I couldn't get the power button to do anything, no matter how many times I pressed it or how long I kept my finger on it. I was able to force the tablet to reboot by pressing and holding power plus volume down for several seconds. Now the power button is working properly again.
Anyone else seeing these or similar issues? Do they sound like software problems or is my hardware malfunctioning? The tablet is still within its warranty period, perhaps I should phone Samsung and arrange a replacement. (No, I haven't resorted to factory reset just yet. Reconfiguring everything is such a pain...)
I can state unequivocally I have not seen either of these issues. In fact I just woke up my Tab S3 to check after it has been asleep for almost 2 days. WiFi is still running and connected and the power button is working. I'd contact Samsung if the factory reset doesn't work (do a Google backup before the reset and it should be able to restore a lot of your configuration... note this has not worked well for me in the past but apparently it has been improved).
I have not seen these issues either. You could try going back to AQI2 to see if there issues persist.

Question Realme GT 5G just turned off - now in bootloop

Hi,
Just few minutes ago my brand new phone just broke on me. I was holding it in my hand, locked screen, like minute later I tried to unlock it to no avail, screen just stayed black. There was a sound when I touched it by the fingerprint sensor, but no light up from behind the screen. I tried holding down power, then power+volume up, phone only vibrated, no reaction on the screen. I've connected it to the charger, and now it seems to be in bootloop - screen is turned off, and every few seconds phone vibrates. I've managed to somehow turn it back on once, phone booted to system, everytthing worked just fine, then I locked screen and it just stayed black, now I can't reproduce that, can't even turn it off, it's just vibrating every so often. Did it really brick in my hand? Software of Hardware? Everything worked just fine, maybe battery was draining a little bit too much for my taste, (15-20%/hour with screen on+lte/wifi) but 120Hz refresh rate+bright setting and AOD turned on 9am-9pm could do that. Do you guys have any suggestions, or I'm expecting trip to the service?
Sorry, but i cannot guess any reason. I am stumped as this bootlooping shouldn't beb happening... Very strange. May be its better to show it to service center guys.
Btw, i had tried this on my previous android phone to shut it down, like a hard shutdown. I had pressed power + volume down + volume up keys together to shut it down completely. Basically by pressing all the 3 keys. If you want to try, you can try it. I have not tried it on my GT, but had used it on Oneplue 2 and Honor View 10.
Hope your issue gets resolved asap...
Okay, I've contacted support via livechat, they told me it's definetly just software glitch, and to resolve this I have to wipe dialer cache (?) and all system settings - I did it, everything worked just fine, but today, again, same thing happened. First time phone just died in my hand, second time it was while listening to music via Pulsar, today I was just sharing wifi as a hotspot, phone randomly broke connection and would not unlock, but still I could tell it was on, because of vibrations and sounds. Not a software glitch after all? If I manage to unlock it I'll just recover it to factory settings, we'll see if that helps, but I don't like the sound of that.
What apps are -you- installing?
Launchers and power management apps are prime suspects...
Otherwise, mobo failure. It may be firmware but how far do you want to take it?
It should run fine out of the box.
Last time I played with launchers was with good old SGS about 5 years ago, only app out of ordinary was AccuBattery to check that SoT drain, but could it make such a damage without root privilages?
