[Q] Nexus S suddenly reboots - Nexus S Q&A, Help & Troubleshooting

Hi,
The past few days my Nexus S suddenly reboots (or suddely shut down) itself when I'm not using my mobile. The reboots take place at the gaps in the battery plot (see screenshot). The (original) Android OS is using more energy than before the sudden reboots. Normally the screen should consume most of the energy. So the reboots may take place because of a failure in the android OS. Does anyone know how to fix this? Or is anyone experiencing the same problem?

Thanks in Advance!

I am seeing a very similar issue. Since about a week or so, the phone would reboot (ask for SIM PIN) when not used for a while. I work 3 levels underground where there is no reception, but this started happening only recently (a week or so) and I have been working there since almost two months.
My phone is an i9023 with Orange Switzerland. Are there some logging tools I could use to diagnose this problem in more detail?

Thank you. Luckily enough, with the update to Facebook Messenger I have received this morning the problem seems to be gone. Still, it is nice to have a diagnostics tool in case it comes back.

Repair (rom?) on XDA Orbit

Hello all,
I've a problem with an XDA Orbit I've recently inherited. It had never been taken out of the box, and was effectively new - but nevertheless would shut down (completely) within a few seconds of being turned on. Once shut down, it would not turn back on unless the battery was removed for a while - not even a hrd reset would help.
The O2 shop said it was a battery problem, but I'm 99% certain this is not the case; if you put it into ROM update mode, it will cheerfully sty on as long sa required. It's only when booting WM that the crash occurs.
As it can go to ROM upgrade, I've tried updating the ROM; this was successful, but the unit still crashes on boot - although it does seem to take a little longer before it goes down.
Anyhow, the question; I remember seeing on here an advert for someone who can replace ROM chips for about 40 quid. Does anyone have any idea who this might have been, or any suggestions for anywhere else to send it? Or, even a fix?
Thanks,
-dave

Nexus 5 Screen Freeze

Was at about 30% battery and the screen froze as in it wouldn't take any touch events. The backlight would react as if the screen wasn't touched. It seems like the touch events just were not registering but the phone worked in the background. Kernel issue maybe? I have been using faux.
Something similar ....
I had a similar experience on the 15th .... took my N5 off the Qi charger and the screen froze when i tried to unlock it.
I hit the power button and was able to unlock and get a few touches in before it froze again.
I was finally able (after much screen off/on cycles) to get down to the developer options and turn on show touches & show cpu usage.
... background processes looked fairly normal when the screen was frozen(touches showed as frozen) ...
I was rooted, stock rom except for xda user Jishnu Sur's N5 camera mod and running a couple tried & true root apps(Stickmount & QuickBoot). Thought some software issue might be jamming up the digitizer i/o causing it to freeze.
Reverted entirely to stock (the Team Win recovery was also experiencing screen freeze - buttons worked fine) including removing TRWP and re-locking the boot loader!!
The screen freezing problem persists ... my conclusion is that it's a hardware issue. :crying:
It's possible you are seeing the same thing, but I haven't seen anything in the forums to indicate it's a widespread problem.
Returning it for a replacement phone ... :fingers-crossed:
Hi,
same problem here from France.
I already returned a Nexus 5, after multiple freeze I tried to format data partition via bootloader, (no rooted phone, following google instructions for stock reset) then the phone crash wile formatting, it never wake up gain.
When I get a new one from google after one or two week same problem appears, and it's append more and more often, since monday my phone crash one time more every night, and all the day today.
A this time I'm still trying to load it sine I came back from work seven hour ago, battery still at 49%.
I think it's and hardware issue too.
I'm very disappointed about Google and I'll never by anymore LG products.
Thanks for reading.

Freezes tend to happen on custom kernels specially if you under-volt it too much. have you done that?

Last week I had the same problem with my new NEXUS 5. IT’S TOTALLY A HARDWARE ISSUE.
LG products are however not so bad in the JAPAN market but still we are expecting a lot from LG technology.
LG services suck.
I am facing the same problem with my Nexus 5. Unrooted, bought 7 months back from India itself, was working fine till around two weeks back,when the lags, screen freeze, blacking out n all appeared. Got it repaired twice at the LG centre. They changed the front display touchpad as well as the charging connector strip. The problem still persists.

Hardware Gurus: is this a hardware problem?

Hi guys
I'm sure this problem is not brand specific but a general issue:
My device (Xiaomi Redmi Note 1W 3G) loses its display from time to time. The screen (1) flickers for a few secs or
(2) during standby it loses power, only way is reinsert battery. Sometimes there is a freeze (3)which means for half a minute the system hangs until it reboots all alone.
My question to you: is it possible some internal wires have become loose, or and other idea?
btw, my device never ran correctly, from the first day on, issues.
So far, I've tried a custom ROM and several global versions as well as TWRP and CWM.
Any help highly appreciated! [emoji316] [emoji26]

Screen flickering issues seem to be common in the Redmi Note series :/... I read that someone who had this problem found that factory reset fixed it, but once he entered recovery the issue came back. I would assume it's a hardware problem with my experience with laptops and desktops (yes they aren't phones though). I don't think that there's a wire that's loose; I think it's something on the motherboard causing the problem, not the screen panel itself. Can you send it back to the person you bought it from and get a replacement?
Thanks for your reply. I've never read about these issues anywhere before, but now I see that this might be Xiaomi's fault. Nonetheless I'm gonna open it up just to check it out as I imported my Note from China. Sending it back would be way too adventurous.
I'll turn my back to Xiaomi, other brands are smaller yet more reliable.

S7 Edge freezing then restarting

Hi all,
Hope somebody can shed some light on this issue I'm facing. This is my first ever post. All your input will be very much appreciated.
I purchased this S7 Edge DUOS (Dual sim version) around 8 weeks ago. Around 3 weeks into my ownership, I've started facing a persistent issue which I've tried to resolve with the best of my knowledge but unfortunately I haven't succeeded.
Randomly the phone will freeze for around 5 to 10 seconds and then restart. Sometimes a pixelated set of lines would appear across the screen when it freezes, a lot of the times they are green.
When the phone does reboot and I return back to the main screen, everything is back to normal and the apps I was using remain opened in the background, so it's not a proper reboot.
There is no such pattern on when this happens, it happens while being used on any app and a lot of the times it reboots while the phone is in my pocket. The only reason I realise is because the phone will be on the startup lock screen.
Battery life seems okay, nothing seems to be draining the battery. Although sometimes it does get hot and drains it temporarily.
I have cleared cache partition, done a factory reset and deleted third party apps. Nothing has resolved the issue. When I did the factory reset, the phone didn't crash for a good few days then started doing it again.
I just cannot work out what it may be and it's getting really frustrating!
I really hope somebody can shed some light on this, I am trying to avoid going down the return route.
Many Thanks in advance for all your help.

Hi my mate had the exact taste problem with his s7 Edge single dim version, it woody of freeze and reboot and pixilated just as u explained and turned out his phone his cpu overheated and this was the result of it, he then returned it to Samsung and he received a brand new handset so best is to maybe return it as it sounds to be a faulty handset.

Phone is extremely slow after replacing the screen

Hi all, I dropped my OPO a few months ago and completely shattered the screen+digitizer. I unplugged the battery and it has since been sitting. Today I received a new screen in the mail and replaced the broken one and put it all back together, but it's now running so laggy that I can't hardly do anything. It is running LineageOS on Android 8. I thought that the screen I bought may have just been a counterfeit with a terrible refresh rate (like 5-10 FPS) but I remoted into it with both Vysor and TeamViewer and they are lagging too, so it seems to be a software issue. I was then planning on potentially trying to flash a new ROM and just starting fresh, but I couldn't get it to boot into recovery, it just shows a black screen and TWRP never loads. After about an hour of fiddling with it I was able to get it back into Lineage, but the issues persist. Any ideas on what may be causing this?
