Unfortunately, System UI has stopped. - Galaxy S6 Q&A, Help & Troubleshooting

Hello,
I have the S6 stock everything on Verizon. About a week ago my phone upgraded to Android Marshmallow. Just yesterday, my battery died and I put it on the charger to fully charge. When powered on there was a new pop up message, "Unfortunately, System UI has stopped." I powered off, restarted with no fix. It keeps doing this and I cannot use the phone. I cannot lose all of my photos and videos!
What is happening here and could you help me resolve or point me in the right direction to instructions for a resolution without a factory reset? I've searched and cannot find any resolution and my next step is to go into the Verizon store as I need the phone/photos/videos. Any help would be appreciated.
Thanks you!

[Q] Errorloop Fix for Memo Pad 8? (ME180A)

I've been happily using my Memo Pad 8 for the past few days. I recently wanted to change my resolution because of an application that was having problems with the stock 1280x800. They told me to backup before I changed my resolution, and I didn't...
I changed my resolution once, my device restarted, and it worked fine, no errors.
I then wanted to change it back to 220 dpi and when the device restarted, I started getting simultaneous errors,
"Unfortunately, System UI has stopped."
"Unfortunately, the process com.android.phone has stopped"
"Unfortunately, Launcher has stopped"
Is there any hope for me?
I factory resetted... which I believe automatically turns off debugging. This hole is very deep...
Is there any way that my tab can be fixed? :'(
I do have root access by the way.
The app that I used is called Texdroider DPI.
Could really use some help here... this was a Christmas present
Still awaiting assistance
Please, this is my first tab
Is my situation really that hopeless? Come on guys, someone has to have an answer out there... this is my first and only tablet!
Still no help? :'(
-sigh- Still looking for a solution...
Does anyone at least know another place I could go to get a fix?
Still waitin'...

			
				
There Has to Be Somebody!
Anybody...? I hate bumping my posts like this, but I really think that some of you out there have the knowledge to help me, it would make my day - week for that matter!

S6 lagging, freezing, rebooting (Gmaps)

Hi folks,
I am having problems with my S6 G920-F.
Whenever I open Google Maps, the phone starts to lag, freeze and eventually it needs to be rebooted by hard reset. Also the font just goes nuts and characters are gone missing ht*p://s12.postimg.org/m5c6mejwd/Screenshot_2015_11_20_21_25_52.png
I was running on Android 5.0.2, then recently upgraded to 5.1.1 but no improvements so far. Did a factory reset a couple of times, booted in safe mode, but the problem keeps on appearing.
Any ideas what else to try, or no choice and send it to customer service?
Thank you very much.

rooted moto g lollipop system ui has stopped no stock launcher... PLEASE HELP!!

hi all,
i stupidly decided to root my moto g - i say 'stupidly' bc i clearly didn't have the knowledge to have that much power... it was working fine for several weeks & then it started having issues booting & charging if i accidentally let the battery get too low. that happened a couple times & i was able to get it working again by charging it in different ways (wall, computer) & letting it alone for a day or so. but then the other day i turned it on & i got the 'Unfortunately System UI has stopped working' & gave me the option to click 'I'm feeling lucky.' once pressed the phone would boot up (though it took much longer than usual) & when it finally did, i'd get various messages such as 'exchange services has stopped,' motorola notifications has stopped,' 'System UI has stopped' - basically everything has stopped & they just kept popping up & then the phone would freeze. before the phone would freeze, in between messages, i could still get into my apps & other parts of my phone, but it would always eventually freeze after a few minutes (or less). i tried various troubleshooting techniques (reboot in recovery, factory reset, etc) which eventually led to doing a hard factory reset. unfortunately, i believe at some point before all the problems started i must have deleted some system things i shouldn't have, including the stock launcher (i was using Buzz Launcher) so now it's returned to factory but missing some vital components.
here's the current state of my phone: it will boot up (though it takes much longer than usual) but as soon as it does i get the message 'unfortunately, system UI has stopped,' 'exchange services has stopped,' 'motorola notification has stopped,' & 'System UI has stopped' again. when i click on 'ok' for that last message, i get the flash of a weird red window & then just a black screen that shows the (correct) time, battery level & phone signal in the upper right corner but it's frozen. before it freezes completely, the only thing i can get into/click anyway is the status bar at the top but the window doesn't even drop down. so the phone is basically booted up but useless.
i've done tons of research & looked into using a toolkit or flashing android/moto stock but i'm using a Chromebook & nothing is compatible with it that i've found so far. & i'm not even sure how to get into the phone via a Chromebook, if it's possible.
PLEASE HELP!! i'm getting desperate. can't afford to buy a new phone right now & i really need this thing to work again.
SHORT STORY: Moto G, System UI has stopped, missing some vital stock stuff, phone boots up, no launcher, Chromebook, last system i was using was Lollipop
does anyone have any idea...? also, keep in mind i'm clearly not as knowledgeable about this stuff as most of you or i never would've gotten myself into this situation. so keep your responses as if responding to Android/Moto G for Dummies. ;-P Thanks!!
Flash a custom ROM via custom recovery
Check out CM11/12. I have the boost 3g version with Blisspop (CM12) and it works great.
Also, if you created a backup before you went root you might try restoring it instead of factory reset.
Make a wipe, or reflash the rom
Chromebook
thanks for the replies guys but my issue is trying to do any of the above from a CHROMEBOOK. in order to flash a ROM though, I need to install the Motorola android device driver & I've yet to find one that's compatible with Chromebook - I'm not sure there is one... anyone have any experience in flashing ROM or any other Moto G fixes from a CHROMEBOOK? thanks.
Can u still access your recovery?

[Q] Many problems with new s6

So I bought the S6, new, never been opened, sealed etc, let it charge the proceeded to turn it on. Then comes the welcome bit and startup, this is where it went tits up. Apparently everything stopped responding, google maps stopped responding, voice commands stopped responding, etc. Thought nothing of it, skipped through everything, got into home screen and then "Touchwiz has stopped responding". So naturally I though oh dear. Oh, it also started restarting on it's own randomly as well, I tried booting in safe mode, disabling things, that didn't work, sometimes it would even get in a bootloop, loop 3 times and then start.
I tried updating it, didn't work, tried flashing it with "G920FXXU3QOLD_G920FH3G3QOJ1_G920FXXU3QOJB_HOME", problems still persist. It's currently on 5.1.1, it wont update in settings, just starts downloading more than 1.2gb's of downloads then says "Software update has stopped responding".
Tried samsungs live chat, was awful, they didn't present any useful information.
I'm wondering if it's just 5.1.1 being awful, because when I boot to the system recovery menu thing where it has the blue screen with android logo, then has yellow exclamation mark, that doesn't reboot on it's own at all. Never reboots in download mode either. Phone is not rooted, knox hasn't been tripped or anything, so I'm left clueless. What do I do? Bought this phone, what, 4 days ago ish. Came here yesterday. My question is, if I flash it with idk, a 6.0.1 update in odin or something, will that fix the problems?
Hi,
It seems to me that you have a defective device, you can either try reflashing the stock firmware and then factory resetting, I believe that it really is a software issue, but as it's brand new (as you stated), you can return it to the store and get another one.
There are quite a few guides to flashing stock firmware back, hope you can do it .
All the best,
~Lord

Why does my Google Pixel randomly reboot?

Hi. My device worked just perfect until 5 days ago. It slowly began to ignore some tasks like opening apps or doing calls.
2 days ago my google pixel with Android 8.0 started to ignore every input i made, like opening apps or trying to reboot. It behaving like this after taking some pictures with the rear cam. After some attepts in opening apps it started to reboot. But instead of a normal reboot it stuck in a booting screen (the one with the Google G and a gray animation bar underneath). It took a while and i waited until it seemed that the OS booted correctly. But after this my device started to reboot randomly after a few minutes. After a while i figured out, that i can hold the power button while the screen with the google G was up to reboot it normally. This worked so that the phone was at least half an hour or more working until it rebooted again out of nowhere.
So far i tried to get it in safe mode and delete some apps like whatts app etc. In safe mode i didnt notice any crashes so far.... but in normal one it does a lot so deleting apps wasnt helpful. Turning on flight mode was not helpful either.
What can I do? What could it be?

Same thing happens with my Pixel, sometimes the phone is just get stuck on some random screen then I have to press and hold it for 15 seconds to let it reboot again. Lately I have started to see another problem, when it reboots bunch of google apps and services stops working and gives hell lot of notifications. All this started to happen after Android Oreo update

I noticed problems with my ear speaker as well. And i cant make phone calls. The phone doent respond anymore when i try to.
Same problem after android 8.0 update
If you have installed the latest Google phone/dialer app, that is likely the problem, was for me.
Find the app in settings and uninstall,it will roll back to a previous version and hopefully fix your issues.

My pixel does the same thing, ever since I updated to 8.0, have you tried doing a factory reset? I haven't done it yet, I have been uninstalling apps for the last couple of days, when it is in safe mode it works good, but when it's not, it freezes and restarts. I'm going to try uninstalling the latest version on google dialer to see if it helps.
I just want to update everyone in case you are having a problem with the random reboots.
I uninstalled the phone update and it was still randomly rebooting so I backed up the stuff that I needed and just did a factory reset. I have been a full day on my phone without any problems. I did a factory reset twice, just in case, for some crazy reason, the phone still had a problem, I wiped it twice! I think you'll be good with only wiping once.
Anyways to sum it all up, I did a factory reset, restored all of my backed up data from my pixel, I had about 120 apps and the phone has not had a problem since. I hope it helps someone else.

Mate, please report if you're still getting the reboots. Mine disappear for two weeks after I do a factory reset and then come back. Same happens in Safe Mode. Bug report claims it's 'Sense Key : Hardware Error [current]' and Google rep says it's a hardware issue (Toshiba's memory or something). Buganiser thread is here.
wrong place sry
Had this on my pixel xl. I was on the 8.1 beta.

Yea, the issue is back, has been for about 2 weeks. This phone is really starting to be a pain in the ass, I can't believe that it happens so often. Did you do a warranty fix?
That's a pity. Yes, I did. Got the device roughly two and a half weeks ago. Flashed 8.0 and then sideloaded 8.1 right away. Knock on wood, all good. But there's still a report every other day in Buganiser of a phone even on 8.1 doing this.
Got mine at release. November 16. Google won't replace it either. I have a one pixel brick
I have the same problem. However, it is not frequent enough on Android P beta. But as soon as I go back to the stable build, it starts to do the same thing. Did you guys have any luck resolving this or should I send it back to the vendor I bought it from. They won't replace the device in Pakistan but may be will fix it in some manner.
