Phone restarting on its own.
I have a Samsung A34. I recently dropped it in water and got a technician to look up and clean it. He cleaned it, he got the moisture of camera and all. But after the repair, the phone keeps restarting on its own. Sometimes it just shuts down on and its own. When i use the phone, theres no issue. But when i dont use it for a while it just keep doing this. This problem started right from the service center itself, and looked it up. He said theres no issue in connection or something, but if i want he will have to check software first (which removes the data) and then the battery and then the motherboard. So what will i do? Will this fix on its own?
