S3 Lock-Up on Calls - Support Please

[Crynosjf]

Hello Android Community,

Allow me to start by thanking you for your help on this!

I am having issues with my Samsung S3 operating 4.1.1 through Rogers (Canada). Essentially, 90% of the time when I am on a call (incoming or outgoing) my screen goes black and I cannot "unlock" it. E.g. I cannot make any entries on keypad, navigate to any screens, etc. no matter what buttons I press. When I am leaving a message for someone, I need to reboot the device by holding the right button for a few seconds, then releasing, to hang up...

Any ideas?

Thanks!

Go into "phone" preess the menu button, the one on the phones lower left corner, select call settings, uncheck "auto screen off during calls". Hope that helps.
