Yesterday when i was using my s23 ultra it suddenly powered off and didn't turned on it shows 0% battery but when i was using my phone before it powered off the battery was about 35%, I just put my phone on charging for 15-20 minutes but after that it didn't turned on. I keep trying different charger, different key combinations, even called samsung customer care but no response at all. When ever i press power button to turn on my phone it shos circle with thunder sign inside the circle and nothing else. 1-2 times it turned on but within few seconds it automatically turned off. Today something magical happened and it turned on automatically but i dont know when it will again turn off. So please help me if anyone know about this problem.
