[Samsung Galaxy S7 Edge Questions and Answers] recmun:
Hi everybody,

So I have a S7 Edge that I buyed in Spain in December 2016, so it has a year and a half by now.

The phone have the Gorilla Glass a bit broken but the display is perfect aswell as the touch, the back is also broken, main issue there was a corner fall but, this either started nor agraviated the issue in hand, it was no difference between before and after that situation.

The phone was submerged in water, less than a meter for less than 5 minutes, again I dont remember that this issue started nor agraviated the issue.

Now the issue I'm not sure when it started but it was this year for sure, maybe 2 to 3 months ago.

As far as I remember the issue started after a Samsung update, a large update like 1 Gb, the phone restarted to install the Update and during the Update it froze while installing the update in the boot and started heating up I wasnt able to do a thing I wasnt able to either restart it nor shutdown it, so I just waited until the batery run out wich it wasnt much time since it was heating up a lot.

After it shutdown I charged it and then started, it was able to update but from that point I didnt want to either shutdown nor update the phone again being afraid of the phone dying, so some day the phone forced another update, and I encountered the same issue, after that once in a while the phone restarted.

From that point I dont actually remember how it happens if I had some issues but one day the phone restarted and entered a boot loop restarting the phone after a second or two of the Samsung ROM splash, so I tried to shut it down and wasnt able to do so, at some point it "shutdown" but with a red led on and I wasnt able to start it, after 3 to 4 days the light went off (batery run out) and then I charged the phone again but wasnt able to boot up, after a few restart it boot up but then restarted and loop again.

After a few tries I was able to Factory Reset the phone and the phone started functioning kinda alright, I installed an app and while using it the phone restarted so I uninstalled the app, after that the phone didnt shutdown, so I used the phone for some days and never shut it down nor let the batery run out, till one day I updated the apps from the Play Store while updating the apps the phone shutdown again, boot loop and subsecuently shutdown with a blue led this time and not being able to start the phone again, so I waited like before, but for some reason the blue light stayed for like 2 weeks, I guess the phone has a lot of charge and the only thing using the batery was the led I dont know.

After all this I decided that the problem was a Software problem since all the main issues apeared while updating apps, updating the system, using apps, etc, so because I didnt have guaranty I decided to install TWRP and then some custom ROM, so I do it so, I installed TWRP, booted into TWRP, backup EFS, wipe dalvik, cache, data and system, in this process the phone rebooted, boot loop and then again blue led and not being able to start the phone, so I was tired by now and I opened the backpanel breaking quite a bit one side didnt care if I fix this I will change the back and front glass, I detached the batery and the phone shutdown then I was able to start it, boot into recovery TWRP and installed HavocOS this time (I will try with another one just in case), I installed it run it and it appears to be working fine... it rebooted one time and after that nothing I installed Whatsapp a 2.3 gb backup started to download alongside 34 apps from the PlayStore I guess the apps that I had in the previous installation.

While downloading the 34 apps the phone restarted I guess while installing Facebook, after that it shutdowns again after apparently working just fine for an hour or so.

So I decided to install again HavocOS but dont instal any APP but Whatsapp, maps and some other things I need (Keepass, Bank stuff, etc) but from here on the phone started to reboot even in TWRP, while installing the ROM sometimes it freezes sometimes it shutdown sometimes it rebooted and antered boot loop but at least it didnt get stuck anymore I was always able to shutdown and start the phone but with boot loops and shutdowns and totally impossible to use.

So now I'm almost totally sure that it is not a Software (free fix) problem, and now I'm thinking in replacing the batery, the batery is not very expensive (compared to a now phone ofc) but it is a bit expensive for my economy and I'm not totally sure that the batery is the problem, can somebody, with all the information given here tell me something like "I'm at least 90% sure that the problem is the batery"?, cause, I'm a PC Technician that didnt know much about phone but they are practically the same as a PC but less modular and sincerilly I think that it might be the Processor or the Internal Storage, both non-easy-removable and change and both more expensive than a batery and both things that I have to buy outside of my country that may or may not come in 1 to 3 months so, is it really worth buying a batery or this issues point to a direction that the phone is almost imposible to fix with the money I have so its better to save money and buy a new one... thing is in this effing country a new S9 for example cost 1000 u$s and my salary is 600 u$s so its a bit anoying to save for something like that, even a new S7 Edge is worth 600 u$s here, and thats what I paid in Spain one and a half year ago when it was the latest Samsung phone available.

Sorry for the long post I wanted to explain everything throughly and I hope my english is ok.

Best regards.
