Hello guys, I'm struggling with a G935F that's been having weird boot and battery failures in the past months, and now sometimes it won't even boot. Phone has been bought in 2016 so it has no warranty.
I've flashed it using '7.0 stock ROM' through Odin, then factory and cache wipe, but nothing changed. 5 days later I could got into the OS, installed firmware update and again this "infinite bootloop and suddenly working again", so frustrating.
More Context:
1) Battery drain anomaly started 3 or 4 months ago, with overheating and a boot loop. Sometimes it got frozen at the "SAMSUNG" logo, sometimes at "SAMS...". But at least, after a few attempts, I could got into the phone.
2) Last weeks, the same issue, charged the batery at 100%, and started to loop-->∞...'til it was 0%. 20% recharge then black screen with blue led until the battery was completely depleted. Full recharge and misteryously started to work.
3) The same as point 1, but couldn't boot or do anything though, so I decided to flash it with the stock rom.
4)Tried 2 different stock ROM's, but the same as point (1) . Today the phone finally got into the OS and it's working fine.
I'll install Superman ROM with Notorious Kernel to see if this behaviour changes, but since this phone isn't mine, I want to take advice from you guys: Is this behaviour a software or hardware problem? Phone used to get overheated but now it's not happening, It's working fine, I'm doing a start-up and shut down cycle to see if the problem occurs at certain battery level. And everything is going fine. So if you need more specific information I think i can run anything safetly.
I have tried 3 different ROM's. Minotaur, Superman and Stock. Customized ROM's won't even install, phone freezes with weird lines, as if it were a GPU fail, it gets really hot until the battery is depleted. After several attemps, sometimes I can access de OS (sometimes with Minotaur ROM), but it freezes in the Google Account input menu.
Here is a log after trying to install Minotaur again.

Hey all,
so after 2 years using my N4 I bought a new battery since I exchanged my display and sort of damaged the original battery (it was bended, smelled strange (could also be the glue) and I had the feeling it performed worse).
In the beginning I was satisfied but now after some time, I have some weired charging effects:
Using the stock rom (Android 5.0.1), I charge the battery to 100%. If I reboot the phone, the battery percentage dropped back to something between 50%-80%. It will the charge back to 100% within a quite short time. If I reboot again, the battery percentage dropps down again, but not that much. This can be repeated several times... Further, if I boot into recovery (TWRP) after reachin 100%, it also shows something between 50%-70%. After changing the battery and flashing Lolipop, I used an app to "calibrate the battery" - don't know if this helped smth or messed up everything.
Furthermore I noticed sometimes, that battery percentage drops down instantly about 20-30% within a sec while using the phone normally.
Is it just a bad replacement battery? Or is it a issue due to Lolipop (can't say if this will happen with KitKat since I changed the battery using the developer preview and stock Lolipop only)?
Right now, I'm trying to charge the battery while beeing in TWRP and see what happens then if I boot the phone.
Edit: Within minutes, battery was up to 100% in TWRP too. I rebooted TWRP and it's now back down to 58%... So it seems that Lolipop is not the reason.
I have sm n900 which is 2 and half year old. I rooted this device in a first week when I bought it. The device was smooth and everything was pretty fine. But recently 4 month ago, I had a first crash while opening camera360 app. The device goes full black and doesn't turns on. I have to pull out my battery and put it back in to turn it on.
And after few days, it crashed and shut down again while I started playing Dominations. It has not crashed on camera360 since then , but has continued its crash by getting shut down, while starting Dominations.
Then, I changed my battery and bought a new one and I still face the same problem. I changed from VN-ROM to CM 12.1. The problem still persists. It only shuts down when I open Dominations. Else, it is smooth for other games like Piano Tiles 2. I don't know what is this. Also, it never crashes when I open Dominations while plugged in. I thought it was the battery issue but I even changed to new battery. Please help!! Below are the screenshot of battery after blackout. The screenshot is from both ROM. One is 4.4.2 kitkat and other is 5.1.1 lollipop. Is this the hardware issue? I think it crashes when it needs more RAM and then sudden blackout..
Hi!
Guys, I have a problem and I have no idea how to resolve it. I was installing a couple of ROMs (of course after rooting my Z2 Pro and installing TRWP 3) first I think Ressurection, and then I stayed on Cyanogen. But unfortunately after installing those ROMs battery started to behave really strange. It was draining from 100% to dead within like 30 minutes...
So of course I went back to stock ROM because I thought that that was a custom ROM problem. But unfortunately the problem remained and it was getting even more strange - it was draining fast to 1% and then it stayed on the 1% for almost the whole day, and it kept rebooting a couple of times. So I rooted the phone again, installed TRWP and tried wiping the battery stats. Unfortunately the problem remained it was either draining and shutting down or it's draining and staying at 1%.
Could you guys help me with that? I think I've tried everything I could, I have no idea what to do next...
First of all -please excuse the thread's title, but I encountered an issue where I couldn't input content in the "title" box unless I refreshed the page and started typing before it loaded the page fully (tried on both Chrome and Firefox - VERY odd).
Recently I've encountered issues with the phone (N910F) getting really hot and shutting down the phone. I was in The Philippines at the time and the daily temp was around 34 degrees so I thought this may have had something to do with it. One battery in particular, whenever I used the camera it would shut the phone down. I stopped using that battery and then eventually the other 2 have been doing the same - they are all after market batteries bought from Amazon from Anker and Rav power and within a year old. But then it would get worse and the phone would just randomly shut down - it seemed to make no difference if it was at 90% or 30, it would just die. I'd often have to do a battery pull and hold down the power button just to get it to fire back up again. Over the last 2 weeks it's gone form a few times a day, to multiple times an hour! I even tried to limit the load by changing the governor to "powersave" and that initially seemed to help matters.
I figured it could be one of three things going wrong - a software related issue, a hardware issue with the phone or failing batteries. I installed [ROM][N910G/F][ODEX]* DQL1 * Multi-CSC, De-Bloat stock, Fast&Light[CUSTOM] and it was a while till anything happened but then once again - it shut down. So I don't see it being ROM related, I'd only added a couple of basic apps too, so I cant see it being a rogue app.
My last N910F had the EMMC failure and I recall that it would regularly freeze or lag heavily then crash and bootloop, but normally my phone just shuts down. I'm hoping that this means it's most likely battery issues, but it seems strange that all 4 batteries would fail within a 5 month period, especially as they were all on rotation. I even took to only charging them (in a Samsung external charging cradle) on an evening when the temperature was cooler. I've contacted both manufacturers but I know that Anker dont have any replacement batteries anymore, so I'm hoping Rav power will replace that faulty battery (that one started to swell a few days ago.
So, what do you fine fellows think is the likely issue that I'm encountering? I don't want to throw good money after bad and buy more batteries if it's likely that it's a phone issue, but I also don't want to get rid of the phone if I can get it working again.....
(I'd been running the Resurrection Remix Rom on Nougat for about 10 months. I went traveling 8 months ago so I didn't update the ROM as I it wasn't super stable at that point and I was happy how it was working - if it's not broke, dont fix it! But after a while I started to have issues and one of the batteries began to swell. I got rid of that one and switched between the other 3)
So, i had this random rebooting issue on stock oreo, after installing custom roms it went away for a while but now the issue is back again, My phone will randomly reboot as if my battery has just died(while plugged in or fully charged).. I can be playing games or just scrolling through my home screen and it will reboot without warning, then starts up like nothing happened.. any ideas on how to fix this?

Hey Texas, I'm not sure how old your battery is. But if your battery is on the fritz it could be losing voltage in your phone will shut down. I think you'll normally get a bad battery warning but I'm not positive. I'm using Alpha Oreo 1.3.1 with MK 2000 version 2.2 kernel. And have not had any random reboot problems. On the contrary. It has been extremely stable and I'm getting extremely good battery life especially with greenify. Normally 24 to 27 hours on a full charge. With anywhere from 3 1/2 to 6 hours of screen time.
