I use Samsung Galaxy M20 and my mobile got off automatically while I was using it. My device was not responding and no buttons were responding. The mobile got off and wasn't turning on. It later showed SAMSUNG logo and was stuck on it. Few minutes later again screen went off and wasn't turning on. Got stuck on the logo several times and later my device worked.
It happened twice today. Can you please give any suggestions why did this happened and how to solve it.
Okay, You are going to have to ship it out for service. For shipping repair, you need to call Samsung, the hotline is indicated in this link: https://www.samsung.com/us/support/contact/. The number is going to be listed on that link, call that number and speak to a representative. They will provide you with a UPS shipping label and will give you all of the instructions.
