Samsung S7 Won't Turn On or Factory Reset -- HELP, Please!!!

[ShyMurphy]

NOTE: This phone hasn't been used in a few years because of the following problem but first some background on the phone.

It is a Samsung S7. Probably about 7 years old. The phone is in physically perfect condition. No bubbling out where the battery is, no scratches, nicks, or cracks. The charge port is in good condition. 

The Problem: A couple of years ago, in August 2020 the S7 just turned off with no warning. It won't show its charging or turn on at all. I have tried forcing a factory reset and the reboot screen won't come up. 

I have tried a bunch of different things. I haven't however taken it to a professional because i had a new phone, which is now super glitchy. If anyone can offer some solutions or help in any way, I would appreciate it. 

Thanks in Advance.,

Shy

Sounds like the battery needs replacing.
Especially if it's not been charged for some length of time.
Not sure if Samsung will still do repairs on a device of this age. But worth a phone call to Customer Support.
Otherwise I'm sure a third party repairer will be able to help.

If you can't factory reset the phone which is as deep as you can really go with the phone then this could be hardware based as well as software.

A factory reset wouldn't obviously help with a hardware based issue.

Have you considered visiting a Samsung Service Centre for them to help.

You may find any costing negligible if it's a software based issue.

With a costing then at least you can weigh up the cost of repair to the cost of the phone @ShyMurphy 

An Un_Authorised engineer may cause further issues.

No disrespect to the multitude of people in standalone shops who effect repairs. 

Would you let us know how you get on  ?
