Has anyone had this problem? I don't have notifications, emails, texts. I have only downloaded some basic apps and the phone is fully charged.
By the way, I should mention this is my 2ND Galaxy s3 in two weeks. The first one died after one day and I had to go get a new one.
What is happening is the phones sensors are kicking in and turning off the screen. The phone has a feature that blanks the screen when you place it against your cheek to prevent you from accidentally cheek pressing stuff on the active screen.
When you tap your finger against the screen the phone also thinks it's your cheek and blanks the screen accordingly.
The fix is how you hold the phone. If you hold the phone exactly like you do when you place it against your ear it will sense you are holding it that way. Change your grip and it will work. Other option is to turn off that sensor in the settings.
Took me a bit to figure it out as well when it first happened to me. Once i figured it out it was a no brainer.
