Random Reboot with Bootloop - Galaxy S 5 Q&A, Help & Troubleshooting

I am currently experiencing this. My phone is a SM-G900F, on stock rooted Firmware (5.0) At times for no reason it will just reboot, then to top it off, the phone will stuck in bootloop. Only removing the battery and powering it up will solve the issue. It seldomly happens.
You have any idea what this could be?

Yup, buggy Android, happens occasionally to mine too - also stock rooted

[Q] Not rooted Note 4 occasionally stuck in bootloop

Hi,
I have a SG Note 4 (n910f), I have not rooted the phone.
Every once in a while the phone turns off and reboots, and then it reboots again and again, it's stuck in a bootloop. However when I wait like 30 minutes to an hour, it eventually succesfully boots and shows my lockscreen, at that point the phone works fine again.
It happens now nearly every day and is getting very annoying.
I only once flashed an original software update from samsung with Odin without voiding the knox warranty.
The only thing I haven't done yet is setting the phone to factory defaults. I'm going to try that today, hopefully it works, but I have a feeling that the problem is hardware related.
I can't get into recorevy mode, and I don't have a custom recovery and i'm afraid if I get that it voids the warranty.
What should I do?
I can't go to a samsung service point when the phone isn't bootlooping cause they'll say nothing is wrong, and if I do go there with a bootloop, it might fix itself again and they say it is fixed, though the next day it goes bootlooping again...
Edit: I can get into standard recovery when the phone doesn't bootloop. Just cleared system data and cache.

If you have a external sdcard remove & try.

random flickering reboot

My Zuk has a weird issue.
Randomly, it reboots itself, and when it boots up the image is flickering. If I reboot manually it stops.
Anyone else experiencing this? It stopped doing that with CM13, but in the last days it started doing it again.
I tried a clean flash but it keeps doing that.
I too have this problem bro. For me it started after i unlocked fastboot. Sometimes the rebooting gets into a loop. Am not sure but I think it happens when the phone heats up.

Flight mode messed up phone

I dont often use flight mode, but when I did recently, about an hour later I noticed the phone was dimly lit and on. It was on the Samsung logo, like it rebooted and stuck on boot. The blue LED was on and the 'kernel not seandroid enforcing' in the corner. Could not turn it off without removing battery. Even when I put battery back in, again stuck on boot.
Eventually managed to get into recovery and wiped dalvik and cache, but still same problem. This is on MM 6.01 stock debloated (either xXx 2.1 or _andr 3.3 devbase). Restored a full backup and managed to boot and seemed to work OK, but it again froze after 10-15 min.
Problem was only fixed when I restored an older LP backup (xXx 1.6). 2 days later works fine even in flight mode. Anyway, googling this issue, seems a few others experienced same, but on LP. Havent seen instances of it happening on MM, but not sure I want to go back to MM so soon.
Anyone else experienced similar issue? And what could have caused this to happen when in flight mode?
Same thing happened to me with the BTU modded MM 6.0.1 ROM G900FXXU1CPDF-BTU, but nothing to do with flight mode, I just noticed the phone dim and stuck trying to boot
I went back to G900FXXU1CPD7-BTU and it's been fine since

Issues after the 6.0.1 update

I'm on Telus, with a Galaxy Note 4 and the recent software update to 6.0.1 ****ed up my phone. It wouldn't install correctly and it finally went through the third time through OTA. I've done a hard factory reset through the recovery menu, and flashed the firmware on it through Kies and Odin multiple times. Cleared the cache. It's still having issues. Slow, laggy, and high battery drain. The OS seems sort of okay if I'm booted but it but it's a little slow. Soon after turning the screen off, I won't be able to turn the screen back on, and I end up having to pull the battery. It will restart randomly and I'm not able to turn it on 9/10 times, with 5 of those going to a emmc_read error download screen.
Do you guys have any recommendations on what to do? I haven't tried a custom recovery so far.

S5 SM-901F Bootloop on device with Custom ROM

I flashed the ROM Ressurection Remix onto my phone to get a newer Android version since the model is quite old. Everything worked perfectly for over two years. Then while browsing, my phone crashed and got into a bootloop and restarts after showing the Samsung Logo. After manually removing the battery and putting it back repeatedly it boots up somehow. I couldn't reproduce what was happening back then.
After that it crashes in irregular intervals for no apparent reason and every time I could get it to boot properly by turning off and on for a long period of time.
Now I got the same problem and I wanted to get rid of the bootloop, so I decided to flash it with a new version of Ressurection Remix. I updated TWRP via Odin and had much trouble to get into recovery mode since my phone was crashing at the Samsung logo. As I got into recovery I made a factory reset and flashed the new rom. But as soon as my phone started to reboot after the flashing, it crashes again and the loop starts once again. Again, I searched for another Rom and used LineageOS but the problem persists.
Now I'm out of options, I can't even get into recovery mode by now.
Could anybody help me out?
