My G1 shutdown twice this morning?

Hey, this morning, I looked at my G1 and checked email. I pressed the off button briefly as I always do and put it in its case.
5 mins later I went to get it and it was off? I had to hold the power button down and it came and and went through the full startup sequence!?
I used it a little and then left it, 10 mins later or so I came to use it and same thing!?
Battery was full as it had been on charge over night.
It's been fine since, any ideas.
thanks

I've gotten a few sudden quits and restarts/poweroffs myself randomly out of the blue. Seems like some leftover bugs in the system software, not a hardware issue.

Nexus 7 random reboot, screen jamming, making noise

HELP,
yesterday, I was using my nexus 7 for normal use, wasn't playing game, just browsing with chrome. the battery was 8 percent when I last saw it. I then proceed to charge it, but the thing suddenly just shut down itself. I thought I misread the battery percentage, so I charge it anyway. about an hour later, i checked on my nexus 7, turn it on, got to the boot screen, got to the home screen, use it for about 15 minutes, and suddenly, the screen black out, it was flickering like crazy, and making some white noise ish sound. I panicked so I hold down the power button and turn it off. I turn it on again, and after about 30 seconds, the same thing happened again. I was using motley's kernel with 520 GPU, and I thought, maybe my nexus 7 cant handle the GPU OC. So I went to recovery, tried playing with recovery for about a minute or so, but the screen didn't flicker at all on the recovery. So I flashed the 484 GPU version of motley's kernel. When I reboot to system, the same thing happened again. So I thought, maybe if I restore to my old backup, it would not be like this any more. so I wipe the data, dalvik, and cache, and I restore my old backup. But the same thing happened again, only this time, after I turn it off, it make a high pitched sound.
I waited for about 6 hours, and now when I turn my nexus 7 on again, it works normally.
So, what has happened to my nexus 7?

I'd say it is the overclock. Graphic cards do some weird stuff when overclocked. You can burn up your GPU doing that and cause it to forever freak out. I always shied away from GPU overclocks.

would that cause any permanent damage?

It should be ok if you reflash back to stock rom to make all the hardware back to reset mode. A warning always given when we try to flash rom with oc created.

i also experienced this one, also received a battery warning and then suddenly screen went blank. then same weird thing happened as the one above. I'm on paranoid android rom and i'm quite sure it's not overclocked or something. Was only able to get back to normal by holding the power button for around 15-20 seconds...

Happens to me
This will happen to me a lot when my nexus 7s battery dies, I plug the tablet in and then immediately try to start it up. It will work for around 30 seconds then look like an old TV without a signal. I am on stock everything, no rooting or custom Roms (yet). I always thought it had something to do with battery calibration being off and the tablet not having enough power to run, because it always works fine when I charge it before attempting to boot.
I have also noticed that every once in a while the screen will have a vertical line of pixels flicker.

Same thing happened to me yesterday...
I got the "low battery" warning and after some time the screen started flickering in many colors and there was a weird static noise.
I pushed the on/off button, but it wouldn't turn on again. After a few minutes of charging, I could turn it on again.
This isn't normal behaviour, is it? Shouldn't the N7 perform a regular shut-down when the battery has no juice left?
I'm on the rooted stock rom btw.

I faced the same problem. I dont know when the battery might have drained out, but on starting the tab on low battery, it suddenly started showing black screen with little grains and suddenly stopped with a noise. I charged, started the tab again while charging, and the battery reading stuck at 21% even after charging for 20 mins. Within 5 mins, it happened again. Now after 35 mins of charging, I start it again, it boots normal, and now its reading the battery percentage in an incremental value (started with 22%) and now its again stuck at 23%
Is this a HW related issue? Or do you think it is more of SW related issue? If it is more towards the HW side, we better have it replaced. Mine is C70 model.

just happened to me... it may have run out of juice... didn't turn on when I tried, so I guess it did... then I put it on the charger, tried booting it, went away for a sec and when I came back I also got this black screen with some flicker and a static noise...
will now try to charge it over night before trying again...

Nexus 7/Google problems
I received my Nexus 7 on Aug 21 after hearing the rave reviews. It didn't come with app for a camera, so I downloaded one.
The camera didn't work. I re-booted it & it worked this time. Downloaded Skype - whole reason for getting the tablet - to stay in touch with family that is far away. Tried to Skype - camera wouldn't work. Rebooted - worked this time again (getting tired of having to reboot for something I want to use to work). On Sept 2, sent message to Google inquiring about camera & app I downloaded. Only response - "thank you for contacting...blah, blah, blah - check out Q&A." All along, the tablet would shut itself down & reboot randomly (battery fully charged sometimes). On Sept 13, I shut it down & charged it. After a full charge, I tried to power it back on. Tried again several times that night & then the next morning. Called Google (who I bought it from). Told them I didn't want a piece of junk that wouldn't work. He told me it was past my remorse period. (The only remorse I have is buying their piece of crap instead of a reputable one.) I finally did get it to come back on, but camera hasn’t work since even after a complete factory reset. Any way – in order to get this one fixed, I have to “buy” a new one, then send back the old one & be reimbursed. Is this a legitimate business practice?

hi,
since today i have the same issue. did nothing special, just swichting from g currents to chrome. stock rom, no modifications, not rooted, everything original
n7 suddenly had a black screen(battery was at 28%). nothing worked, no powerswitch(10-30 secs). when connected to original power supply and cable, it boots up.. google logo .. glowing X.. lockscreen. then, approx. 30 sec later it turns off again(screen black). usb cable still connected. after some time it comes up again.. and repeats the procedure. after some cycles it stops, and when i reconnect the usb calbe it starts over again. sometimes, before it turns black, it shows a flickering screen and sometimes fizzling sound.
any suggestions?

I had this same issue right after the 4.2 ota update, after leaving it on charge overnight it seems fine now after a couple of discharge / charge cycles
Its like after the update it was over estimating the battery level

Same thing!
I have a completely stock Nexus 7, and the EXACT same problems are happening to me too! The first couple of times it happened my tablet would reboot normaly. But now, my tablet won't boot up at all. Any suggestions on what I should do? Also, remember, I have no mods installed.

Happening to me too.My N7 shut itself down because of low battery a couple hours ago and I haven't been able to get it to boot since. When I plug it into the charger it shows a flickering screen like a tv with no signal but with less white flickers. I've tried multiple chargers and cables but I could only get it to boot up a couple times and both times it did not show that it was charging even though it was plugged in and the battery was at 0% so as soon as it boots up it shuts itself down again because of low battery.
So now I've got it on the charger, screen all a'flicker, waiting for it to get a charge but I've got a feeling its not even charging because, like I said, the few times it has booted it showed the battery at 0% and not charging.
I guess I'll try to leave it alone for a while and see if it will start up after being plugged in for a bit.
EDIT: I let it sit there and charge for about an hour or so (with the screen flickering) and I was finally able to get it booted. It said it only had 3% battery but now it seems to be charging as fast as usual.

Yup... I've let mine sit there turned off and charging over night... helped!

Just had a problem with the Nexus 7 not charging when battery was likely fully depleted. Putting a charge cable in was automatically booting the Nexus 7 up and wouldn't charge shutting down right after. Loops going on and off. What I did was plug a charge cable in and hold power+both volumes and now I believe I am charging at the bootloader screen. It stays on so I will leave it like this and if it doesn't resolve the issue I will try recovery once it is charged.

I've just started having the same issue. Has happened twice when battery gets to 8%, suddenly jumps to 0, shuts down, then after a few seconds restarts itself. Gets to home screen for a few seconds, battery showing 8, then jumps to zero, switches off and has flickering blocks on screen with static noise. This keeps repeating, only way I have found to solve it is to load into bootloader, then select power off. Device charges normally then and once charged works fine. I am unlocked and rooted but running stock 4.2.1, think I'll just have to return it for a warranty claim.

Based on what you experienced, the lesson here is your device can't handle the GPU over clock of more than 446mhz or it will do some crazy stuff.

Nexus 4 wont turn on

Hey everyone, Im having a problem thats making me worry. I was using my phone today and for some reason the phone wont turn on after I turned it off. I havent dropped the phone at all and it hasnt been abused in any way. The last thing I was doing before I turned it off was trying to send feedback for the Yahoo Mail app because it wouldnt sync automatically, but even that was unsuccessful because it wouldnt send. So I thought I should just reboot it but afterwards its not turning on at all.
I tried holding the power button for at least 20 seconds and still nothing is happening, and I tried plugging in the power cord to see if that would help but it hasnt. Has anyone gone through a similar issue? Please Help
Thanks.

Leave it plugged in for fifteen minutes without touching it.

Try holding volume up + power to see if you can get into recovery then reboot from there.
Also, give some more details about your setup...
Rooted/Stock/What Rom/Kernel?

Yea I left it alone for a bit and then I held the power button while holding down both volume rockers and somehow it turned on. I dont know why this happened but I'm just glad it turned back on, it gave me a good scare though. I just hope it doesnt happen again

Mine is completely stock, I havent done anything with it yet

And may I ask what was your battery percentage level like after the short charge? Maybe the phone drained it all just being turned off... There were some cases of this here...

i wanted to add that i had a similar problem with my phone not turning back on. However, I managed to fix what was wrong by just plugging in the usb cable. I know you've tried it, but just in case someone else stumbles upon this thread (like me!) and has a problem turning on their nexus, I wanted to share my experience.
I haven't done anything to my phone other than add my old apps to my Nexus since I received it 1.5 weeks ago. It's stock. I've never dropped it or gotten water on it or anything. I charged it overnight last night and stuck it in my purse on the way to work. I think I briefly saw a working screen after I unplugged it this morning. However, the first time I tried to access my phone today was after I got to work. It wouldn't turn on, though that pinkish light at the bottom was still blinking. I tried calling it and the Nexus wouldn't ring even though the call went through a few rings and then onto voicemail. I tried holding down the power button for a while and also holding the power button with the volume keys to see if that would work, and it did not. Finally I borrowed a usb cable to plug it in, hoping the jolt of power would wake it up. That worked. It gave me the charging symbol for a little bit and then gave me the startup/loading screen with the glowing x made of arrows. I checked my battery and it was at full charge. Well, it was at 85%, which is odd since I plugged it in for about 9 hours last night to charge and there has only been 3 hours of non-use since I unplugged it. Also, if it was really turned off during those 3 hours it shouldn't have ate up any battery. Anyway, I just wanted to throw in my 2 cents in case anyone else has this problem. My brother, who gave me the Nexus, told me that he only has 2 weeks to return it if there's something wrong with it or I don't like it. Needless to say this gave me a scare, since the 2 weeks is almost up.

Yes this happened to me the other night. I was making a phone call and accidentally hit the power button. I then tried to turn the screen back on in order to hang up the phone and it would work. I tried holding the button for 15 seconds, tried pressing the volume up/down keys, and still nothing. I then put it back in my pocket for a minute or so and tried again. When I did that the screen came back on and the call was still active. Very strange, and I hope it doesnt happen again....

Same thing is happening to me right now.
Running stock. Not rooted. Phone charge was around 70% and I was on twitter and the app force closed. So I decided to restart my phone then went to turn it back on and it wont respond. Tried holding down the power button for 20 sec. Volume up and power, volume down and all 3 at the same time. Still nothing. Leaving it on the charger for awhile and the screen is blank no battery logo or anything.
Not quite sure what to do now?

That's scary

My Nexus 4 use Stock Rom, Rooted. and this first i get this problem. Please advise me on this case. Thank
:laugh:

I'm having similar problems. Lots of random rebooting and refusals to turn back on sometimes, even though the LED at the bottom is flashing so i know the phone is still powered up. Also, sometimes when i have it plugged into a computer through usb it will get extremely hot and completely shut down, not turning back on for a long time. I called the google play store and someone is going to get back to me. I love my nexus 4 so i hope i can get this fixed or a replacement.

Nexus 4 crashed and would not power on

I had this issue too a couple of times playing Pandora through my car's Bluetooth. That was when the Nexus 4 had 4.2.1. I have not had this issue with Pandora since the upgrade to 4.2.2.
However, I just now had this issue with Movie Studio app and exporting a video I edited. It turned off its screen like normal screen timeout but then would not come back on.
I had to Volume Up + Power button for a few seconds and then release to get it to reboot.

This same thing is happening to me. Haven't found a specific cause...

Just got the same issue
Today got mine not turning on.
Managed to turn it on by holding volume up and power button together for about 30 seconds while phone was on a stock charger. After that I saw blinking orange led. When I resolved buttons there was a battery pictogram. After pressing and holding power button I finally got turning on vibration and Google logo.
The only things a made after the charging were making few photos of my cat (from the lock screen) viewing them in gallery. Then I locked the screen and put the phone on a shelf. In a hour I was not able to turn it on.
My phone has stock rom and only few third party apps installed.
I got muy Nexus 4 on 21-Dec-2012. 4 days ago I flashed to Android 4.2.2 which phone dowloaded itself. After flashing phone was rebooted.
What I noticed is that it shows 70% battery. But It was fully charged few hours ago.
30% in 2 hours! In my opinion some service/app drained these 30% by using 100% of processing power that caused overheating and/or hanging.

I too have just had this problem. And I've had it previously when making calls, the screen simply won't respond at all, its quite annoying.
This morning my alarm went off and the screen wouldn't turn on, it went on for so long I almost threw the phone across the room. I eventually held the power button and volume down/up button and then the led blinked orange a few times and the phone reset, now it seems fine.
Its a very annoying problem, and could be very serious depending on what you are doing, might have to phone the play store and tell them.

This has happened to me twice now. First time was a month ago and the second time was this morning. Phone was at 100% just woke up checked my messages turned off phone 10 min later it will not turn on. Un plugged cord re plugged cord nothing finally pressed up/down vol and power for about a minute (long minute) and the phone rebooted. YIKES!
Every thing seems normal now but I hate that scare and the fact that it has happened to me twice. Full Stock, not rooted.

Happened second time.
I was able to turn it on again by following the same steps. But this time I got some strange issue: after resolving vol+ and power buttons I saw battery pictogram with some frame with a blue background; when phone finally booted up this frame and blue background were visible through the my desktop background an screen itself was much lighter with pure colors. Only after about 5 soft resets screen seems to became nice again. Each reboot caused blue frame to become less visible. I'm confused and worried.
Also during all these reboots this frame with blue background was visible even in behind "Google" and "X" logos during booting up.
Another strange thing is that on screenshots I made this frame is not visible.

That would have to do with LCD or software..
As the battery & Google are just pictures that change. If you understand what in saying lol ?

[Q] S4 won't turn on, looks dead

Hi.
So, yesterday evening I plugged in my Galaxy S4 I9505 (international, and running stock Android 4.2.2) since it had low battery, then set the alarm clock and went to bed. Today I woke up, checked my clock (not the phone's, my actual clock), and since it was earlier than when my alarm would ring I took the phone to check my emails a bit... only to find out that the phone was stuck on the lockscreen and was not responding to anything. Perplexed, I took the battery off, put it back on, switched the phone on and it seemed to work fine, only to freeze again after a few minutes. I took once again the battery off, put it back on, and this time it didn't turn on at all. I tried several times, tried also while charging, but it doesn't even seem to charge, the led is completely dead. I tried to boot into recovery, nothing. Once or twice when I tried to turn it on it would show on the upper part of the screen an extremely fast and small red text, like the ones you see in recovery but red instead of green, but it was so fast in appearing ad disappearing that I didn't even have time to read it.
Then I tried googling the problem, and of all the different methods only one seemed to work: take off the battery for 10 seconds, put it back on, press volume down + power + home. Which I did try before, but without waiting before putting in the battery again. I tried it this time with the 10 seconds of waiting (while not plugged in to the charger), and it worked. The screen asked if I wanted to flash a CR or just restart. I choose restart. The phone immediately died again and didn't turn on, not even with the method that worked a few seconds before.
I haven't been able to turn it on since then, and I've tried everything. I'm quite desperate, because I have AADD and I do everything with my phone, it's my lifesaver and the only thing with which I'm able to organize and remember stuff (including my daily meds). Also the only thing I never forget to bring with me. I literally can't stay more than a full week without it, is there anything I can do or try to make it work again?

Is there really no one who can help me?

Bricked Zte Axon 7 and I don't know how or why

Heres the entire story, I woke up my Zte was at 100% so I went to school and it was working fine until I took it out of my pocket and noticed it fully shut down so I booted it up and went on, the same thing happend like 6 times through out the day until I started to uninstall some apps I had that might have been causing issues, which it wasn't fixed by that, so I got Malabytes Anti-Malware and ran a scan and no viruses, which I uninstalled after using. Then at around 2:00PM I was on my Zte it had 40% battery left while I just booted it up for like the 10th time and it loaded and once it started I was looking on the home screen and it randomly froze for the first time and it had like a glitched thin line thru the bottom side of the screen going left to right, I stared at it for a bit looking like what is going on, then it shut off and it was a abnormal shut down, the screen went black and turned off as apposed to a normal shut down it will run some text on screen saying "Shutting Down" the vibrates which that didn't happen. So I was like this was probably what it was doing in my pocket so I tried to boot it back up and it was unresponsive and it turned off with 40% so I know it wasn't out of battery. For the next 10 min I kept trying to turn it on and it didn't work so I was like I will let it rest. So 40 mins later I tried it and it went to the Zte boot screen but never booted up it was stuck there I couldn't even turn it off with the Power off or Volume + Power buttons combo, and yes the power and volume buttons worked prior to this. So I was like well this is weird I will let the battery die then charge it then boot it. So it died then I plugged it in the wall with all original charging stuff, I woke up next morning and I tried it and it vibrated and it has nothing on screen and a Red Led and it has been like that since, the battery is gonna take a lot longer to die hence it has nothing on screen it is just black with a red led. I love this phone to death it has kept me from being bored in school and now i'm back 2 being bored. I particularly want to fix this my self and not have to send it somewhere for repair and I would also like to save the data on it as well if possible but if not I would still rather have a phone.
HELP ME EXPERTS! Thank You! :laugh: :good:

These phones don't age well unfortunately. Don't feel bad it's not your fault. RMA if you somehow still have warranty. If not I'm sorry but your screwed, most likely the emmc chip went mad and there's no repairing that for an axon 7. I know, they're nice while they last.

You run stock firmware?if yes,you always be on stock?
