WARNING: not a native english speaker.
when I try to start the phone the following occur:
the display light turns on, shortly after that the phone emits that startup vibration, the backlight remains on for aprox. 85 seconds then the phone aparently shuts down. that meant, the backlight of the display turns off.
problem history:
I was at work and as usual i was listenin to music via handsfree. while my phone was in poket it seemed that somehow my poket pressed the sleep button and turned the screen up. no prob here. i got the phone out of ma poket. reverted the volume @ maximum and then locked the phone and turned the screen off and putted back in pocket. after some time i wanted to change the song. got out the phone, turned on the screen but nothink apeared except a horizontal line in the middle of the screen. I tried to shut down/up the screen but nothink apeared. after a couple of tries the screen turn on but it was unusual what i saw on it. I saw a sketch of the energy rom home screen with diferent colors.
Meantime i was tryng to get the screen outta sleep the music still played in the phones.
I thaugt that a reset will do but it didn't. got out the battery and got home. reasembled it, powerd up the phone and voila! the phone started up normaly. got out the battery, introduced the sim card. powerer up the phone but bad luck. the happiness was short lived. the problem camed back. another thing i noticed is that when i powwer on the phone i let it on but it wont output that energy rom bootup sound.
Can someone elude me with whats the problem with my phone?
hope I was clear enough!
Have a great day/night!
UPDATE: LEFT IT OVERNIGHT WITHOUT THE BATTERY AND NOW ASSEMBLED BACK. IT'S WORKING BUT I THINK IF I GIVE A RESTART THE problem will come back.
Hi
Strange occurrence today. Turned on phone--nothing. Reset battery and it booted fine, but after awhile (when the screen timed out) it went back to black. When I turn it on it goes to dark blue (BSOD?) but nothing else happens, however as soon as I reset the battery, it will boot successfully and as long as the screen is on, the apps seem to work etc. As soon as I lose the screen, I lose the phone again. Volume down followed by power switch brings up the same BSOD.
The lcd is on and the phone is apparently charging regardless.
Can anyone help get me back in business?
Thanks
My phone just arrived. I've plugged it in to make sure it's alive, it stated low battery so I've unplugged it and moved elsewhere. Now ever since I plugged it back in, it vibrates, constantly. It even plays vibrates over the top of it's constant buzz. It operates perfectly fine otherwise, it boots and I've set up my google account. Just curious if there was a way to solve this besides waiting out the battery.
Edit: smothering the power button to force it to turn off, even when it refuses to turn on due to lack of battery or even show anything on screen does stop the vibration. Guess it's a faulty device or something :/ *sigh*
Turns out that as soon as it vibrates it continuously vibrates at a low mode forever. So it can be fine until you plug in a charger, or receive a notification, then it's back to perma vibrate.
I don't understand how exactly can I explain the situation, but I'll be as specific as I can. Please try to understand and help me from this.
My Nexus 5 is on Marshmallow without any roots etc ever. Now, the problem goes like this:
Suppose I press power button once, then screen should turn on/off once. Now this which happens normally in any phone happens in mine for first few times, then it starts like if I press power button once to turn screen off, it goes from off and turns back on, I again press power button, again from on it goes off and back on, this keeps on happening until I try my luck for it to off, but then sometimes it happens like after so much pressing it eventually show me "power off" option on screen(which generally should open if I hold the power button). Now once I encounter this "power off", no matter what I do, I power off/not, it'll automatically turn off, and this happened atleast 10+ times till date. So finally whenever I encounter "power off" option, which sometimes comes when I try to turn screen on or sometimes off, but never I hold the power button, but finally even If I don't click on power off, it'll power off.
And that isn't yet strange till there, normally now "Google" shows on screen when device is powered on, but here after encountering "power off" it shows "Google" and turns off.
This problem has happened to me from maybe starting a week ago, atfirst I ruled it as maybe hardware problem, cause after 3 factory resets, nothing changed, but then when I did wipe system cache and data format from recovery screen, everything got resolved. But this too remained for 2-3 days, again same problem started after it, I this time cleared system cache from recovery, and this time too it helped somewhat. so I can atleast say that it isn't a hardware power button problem, but something which I don't know what, always creating problems from software.
Now this problem has developed itself, because now the power button is kinda working okay, but now the "power off" comes on screen automatically, I can say once-twice a day, and as explained 'n' times before, once I encounter this, mobile turns off.
So everytime I've to turn phone on after this, and pray that it doesn't repeat, but it's yet going on, and i'm so pissed off by this phone, I regret buying this, honestly as till now mentioned I tried whatever I could/I knew, but nothing, nothing's helping me.
Also the problem intensifies when phone is on charge & "power off" is encountered, then the phone goes to turning off and "Google" is shown, then it shows "Google" then turns off, then it shows "Google" then turns off, and this loop keeps on going.
Finally I hope i'm as clear as possible, if someone can please help, I can guarantee any kind of format will just resolve the problem for few days only, and hardware power button problem i'm not feeling it as formats basically help it great, but anyway if I'm going wrong somewhere/need proper explanation somewhere then please tell but resolve this asap.
Phone's from India and it's been 1 year since bought and atleast a month from the Marshmallow OTA update and this problem started randomly without me doing anything I guess from a week ago.
I think you should take a look at that power button.
It's your battery. I was having the same problem with my nexus, I replaced the battery and the reboots are gone.
Mine did this exact thing a couple of weeks ago. really annoying and couldn't put my finger on it, until i got so annoyed that when it came up with the power off notification I repeatedly pressed the power button for maybe 20 times, this resolved it for a few days, though to be honest, the best advice that someone posted, was that a sharp shock to the side of the phone that the button is on resolved it, been over a week now and it's been fine.
I put it down to the case i had on it, harbouring small dirt that was getting into the button housing and interfering.
try it out, failing that, perhaps a new power button, i did have one in my ebay basket, though i don't need to go down that route, not for the foreseeable anyway.
**edit
incidentally, i went down the software route too wiping caches etc. no avail.
Yesterday the phone did not wake me up, holding the power button it directly booted up again, just like it was turned off.
The battery was charged at 55% and there was no update in recent days, so I doubt its a software issue.
The same happened today as well... This is starting to bother me.
Is there any way to find out why it shut down ?
Don't know how to help you with finding out what causes the shut down but I'd check the "planned shut down/turn on" option in battery settings. Even if that's not it you can try to use it to force the phone on before your alarm goes off.
