[Q] Lollipop random reboots - Galaxy S 5 Q&A, Help & Troubleshooting

Hi
I just got this phone for my wife and all is well, but I have heard that the Lollipop update is quite bugged.
We are experiencing random reboots.. With twenty or thirty minutes interval...
Is the random reboots a known problem for lollipop or is it just this phone being a candidate for repairs?
Any other bugs I should be worrying about?
All best and thanks in advance..

Did you factory reset the phone yet? Upgrading to Lollipop from Kitkat leaves rubbish files behind that a factory reset fixes, myself included have reset and it has fixed just about everything

I'm running Lollipop and never had any random reboots. Its running very smooth here. If you updated from kitkat perform a factory reset after update.

Hi
It is the G900F nordic...
And The battery drain is insane...

What I would do; reflash the actual Rom via Odin.
If this doesnt work: downgrade to KitKat and back to lollipop again.
Afterwords everything should be fine. Dont forget to wipe after every flashing process.

[Q] Factory reset before 4.4 update?

I've been out the xda loop for some time now and recently got my Moto G. As the kitkat update is looming I was wondering if it is still adviseable to factory reset 4.3 before updating to 4.4? Not too long ago when people updated android versions they tended to have trouble and the best way of having as little problem as possible was to factory reset first before updating.
Is this still the case these days?

I always reset after the update, so all obsolete files can be removed.

[Q] Downgrade 4.4.2 to 4.3 Galaxy S4?

Can anyone help me please? I've never had an problems upgrading or downgrading my old Galaxy S2. I got a Galaxy S4 last year and it was running perfectly.
A couple of days ago, I was backing my phone up through Kies and it said an update was available. I didn't use Kies to update my phone though as I wanted to back up my data first. I disconnected from the laptop and did an OTA upgrade.
Huge mistake!
Since the upgrade, my phone keeps locking up/freezing. The gallery app freezes constantly. If I try to attach a photo to a Fabecook post, it freezes my phone and in all cases, the only way out is to restart my phone.
This update has left my phone worse than useless. I can't do anything on it without it freezing.
I've tried factory reset quite a few times. I've wiped cache partition a few times. I've taken the SD card out. Nothing works.
I've read that the new bootloader renders it impossible to downgrade.
If I find an official 4.3 Jellybean firmware, will I be able to revert back to Jellybean by flashing it through Odin?
Otherwise, I'm stuck with a phone that no longer works.

If you flashed your 4.3 will activate Knox reading your warranty and your phone will now be invalid
4.4.2 is very good for me
Obviously when you have something wrong

Does this mean I'm stuck on 4.4.2? I really want to go back to 4.3 as that was stable.
Do you know anyway to fix it please? I use my phone constantly for work. I can't use it as it is.

You can go back to 4.3 but you will lose your warranty as I told you
4.3 It is possible with custom kernel or full custom rom

So it's possible to download original 4.3 firmware from Sammobile or somewhere else and flash that? I'm scared of bricking my phone.

If you flash stock ROM by Sammobile or Samsung Updates
you have problems with the modem, Wi Fi,calls
You can avoid these problems as flashing custom kernel

Thank you all.
I think I've fixed the problem without having to downgrade.
First of all I formatted the SD card, I switched my phone off, removed the SD card and restarted it. Then I did a couple of factory resets, turned the phone back off and reinserted the SD card.
I think with it having a complete wipe of everything, it fixed the problems with the phone lagging and freezing constantly.
So far, so good.

Update to kitkat becomes so laggy

I got my s4 a couple of days a go with 4.2 and everything is smooth, then yesterday i updated to 4.4 and everything is also okay after a couple of hours everything becomes laggy, cant even open any app, can go to home screen, just pure lag. Anyone else experiencing this? also I'm using i9505.
welcome to Android.
try to wipe data/factory reset & cache
this would fix the problem
Just restart ur phone and wipe cache and dalvik cache.
Sent From S4 I9500 Crash Rom Final 4.4.2
But I'm just on stock and not yet rooted, the only solution i found is restarting the phone, then after a while becomes so laggy again. any permanent fix for this?

[Q] Reboots after 4.4.3 update

Hi, N4 of my brother after upgrade to 4.4.3 got strange random reboots, I'v searched for long time on google and here but seams an isolated case.
I'v flased latest 5.0.1 stock, and got reboots too, I'v installed kernel hellscore, and same issues, I think that may be high voltage, so I'v UV abount before -100000 and after -75000, but no way, that phone after 4.4.3 ota got random reboots........
Any idea please?

Did you do it from the stock recovery?
If yes, then you might be facing a hardware issue, which is beyond our reach here. I would recommend going to a service in this case.
Ok Tnx

Random reboots after nougat update

Anybody else's phone rebooting every few days..?
It hard reboots (Galaxy S7 edge screen), so i thought it might be hardware failure.
Haven't downgraded to 6.0 to check.
I don't have an sd card inserted (because the one i had corrupted which caused my phone to randomly reboot, now i took it out and it still does it)
Also, I noticed that every time it randomly reboots, the battery percentage drops significantly.
G935F, stock

Before you updated to nougat 7 did you do a full and complete wipe
which includes wipe system, data, cache, dalvik cache and last but
not least did you do a factory reset in twrp recovery before odin
flashing the Nougat firmware?
Are you 100% sure that you odin flashed the correct Nougat 7 firmware for your S7 Edge?
Flashing the wrong firmware can cause rebooting issues and fast battery drain.
Flashing without doing a full and complete wipe can cause rebooting issues too.
Good luck, have a great day!

well, i had a clean 6.0 install which upgraded to 7.0 via ota (UK BTU firmware),but thanks i suppose
(and i also factory reset 7.0 many times)
I am getting random reebots since nougat. I flashed the bell nougat (in on Rogers in canada) and then flashed the Rogers CSC. Things seem to check out so I'm not sure what's wrong. I am going to try to get the Rogers nougat files and see if that addresses the issue.

I have the same issue.... I have unlocked phone on a thai carrier
You DO NOT have to do a 'factory reset' every time you have an update, not even for an operating system update.
I don't know where this comes from but it's stupid.
These updates are designed to integrate with existing systems!
You are as likely to solve any issues with a few reboots.
If you have a problem it's likely due to software conflicts of an app you've installed, not the operating system. Android is pretty good sorting itself out.
So, you do a factory reset with all the hassle of trying to get things back to where you were and then you install another app which causes an issue and ...
Pointless as are the cache wipes always suggested. Android is good at managing resources.
At least with a cache tidy up you're not back to square one
I wished folks would stop suggesting factory resets at every opportunity. Mad.
I get them too, i`m on the lastest NEE software updated via ota. Randomly, when i get it out of the pocket, it says enter pin number because your phone was restarted, i`m using fingerprint lock.
Hello I have a Galaxy S7 and since the update to Android Nougat 7.0, my phone restarts randomly, it can stay an entire week without restart and it can also restart 2 days in a row. It's totally random. I have reset to the factory settings and I have reinstalled only the most important applications (facebook messenger, viber, yahoo mail) but unfortunately about ten days after reset, the problem has reappeared. What could be the cause of this problem? For info, the firmware version installed on my phone is: G930FXXU1DQBO. Also, I saw on SamMobile that the countries that received the update later, had a new version. Could the problem come from that? Is this a bug in the firmware installed on my Galaxy S7. Thank you in advance for your help.
Sadly I have the same problem. Oddly enough this is my first handheld which I didn't root and the first I am running into such issues with.
Got a OTA update to Nougat and I am getting almost daily random restarts.
I wasn't able to discern any patterns so far. Sometimes while it is charging, sometimes just being in my pocket. It doesn't run hot as if an app is running havok nothing.
So far I cleared the cache and that seemed to help but alas it started again.
Does anyone have an idea what is left to try? I would do a complete wipe, but others reported that it did jack for them so I am hesistant to try it.
Sorry for My bad English, i m italian.
Try to remove Chrome. The issues is there for me.
Bye
I have some problem. Not to mention battery life severely reduced after update to nougat. usually 5h screen on time to now 2.. max 3h. SAD.
Samsung Galaxy S8+ Random Reboots
Same problem with my Samsung Galaxy S8+ running Nougat. Purchased the phone from AT&T and received it 3 days ago. It randomly rebooted twice so far, once when I was looking at photos and once when using the play store

I have the same problem. It is completely random, it can happen every 2 days or once a week. Even after a factory reset, this problem of random reboots still persists. The firmware version is G930FXXU1DQBO and I still have not received a new update. Have you solved your problem?

Do you reset your phone to factory settings? What is your firmware version? It seems that the old versions are not very stable.

No, the problem is still here, i did not receive any software updates so far. Sometimes it reboots even twice a day, random, sometimes 2-3 weeks without reboot. Waiting for ota update, maybe it will solve it.

After receiving the February version, did you receive a corrective update? If this is the case, it may be the update that has solved your problem.
