I have had my Galaxy S5 for less than 3 weeks, in that time the power button has stopped functioning, it started off requiring a prolonged press to get a respond, which was a lot different from the S3, which I switched from. I wrote it off as just being how the S5 is. However now it has stopped working, it works for maybe 1 in 10 presses. Has anyone else had this problem?
I just got a new s5 and we are having the same problem. Twice I have not been able to turn the phone on. I opened it and removed the battery to fix the problem. But we have only had the phone for a few days.
