Hello.

Suddenly the phone got stuck on Logo screen. It was on charge for 10-15 minutes and was not hot. Volume Down+Power keys were resetting but the result didn't change. Upon pressing Volume UP+Home+Power key - the screen could go black and no responsive again. Red led was persistent all the time. After some time Volume Down+Power key again could work bring the screen back to Samsung Logo screen - that's all.

I left the screen on to drain battery faster. It drained.

When I plug it to charging the Battery icon appears but it also gets stuck. No Green dot blinking or % progress. Also Red led light doesn't turn on anymore.

It doesn't react anything except power reset maybe - however that doesn't make a change - the phone restarts(?) & shows only the information it got at first second - that's all. I plug out, it drains again so screen turns off. Then I repeat the process - no change.

I am on a trip and I do all primary things there, so it's very frustrating loosing a working phone.

Is there any other ways to troubleshoot and fix it?

Thank you.

Thank you.

I'm not sure - got it from my friend and I resemble him telling something about battery change I think. Will ask him tomorrow.
You think it can be battery related issue? It held the charge pretty well before got drained completely.

Sorry I replied to the general thread, instead of your post. Please look below.

No worries I see your reply

Possible but going to boot logo that's usually means soft bricked phone , can you get into the recovery menu?

It was going to logo screen before - upon crash(?). Now the phone screen lights on after I plug it in - and shows Battery charging icon - that's all. No progress and no response. Can't get to Recovery menu. If I try - the screen will get blank (like it did with logo screen stuck).
Before drain, I had to use reset again to get the screen bring back. The reset was not responsive every time, but from time to time I could get it back to logo screen from blank.

Sounds like the battery, I believe this is sealed in the phone and needs to take apart to replace might not be worth considering the age of your device

I see.

Tomorrow I will go find some phone service to ask about it. Well...if to consider that I can save information - it might be worth - which depends on the price they will ask. I have limited time here - it is sad that will have to get busy with it instead of seeing the city.

Update:
The service center put a new battery - the issue remained with boot up screen. So it was not because of the battery. The cause could be a malfunctioned motherboard - which I think is very possible.

They assumed it can be related with motherboard and price for repair in laboratory (without part change) could to be ~120EUR. That was too much for an old phone. Maybe I will try to show another place on the next days.
