I want you to tell me what is the temperature on your phones .
I got mine for 5 days now ,made an factory reset with no backup and S10 is still warm. During charging is like 39 and in normal use is 33 ... I think it's too hot.
Can you tell me what is the temperature on your phones ?
One reported 60 C.
Thats insanely hot and never should go that high.
Other than charging and gaming, 36 to 45 is acceptable at times and then reducing later.
I am OCD about temps.
So any having above 45C and not reducing or nearing 50 is grounds for RMA or diagnostics with samsung.
I don't know if this is normal but my screen is hotter than previews Samsung phones (s8, s9) in average the temperature is 36-38,5 I don't know if this is OK. Or should I go to service.
