Rom issue s3 hellllp with S5 sensation

Right i have a s3 rooted anyway i used to have resurrection remix rom loved it but wanted a change as someone told me s5 sensation was out so i wanted to see what the rom was like and what difference it was having s5 software on a s3 and it started out ok but i have noticed every now and again if your playing a games the phone will go to the main screen with no notice you could be texting someone and it goes back to the main screen. Normally to stop this i turn it off and back on again and it works ok but then 2hrs later it starts again.

My problem is i have tried installing Resurrection remix rom again as they have a new one and it keeps saying there's no data if i try to flash any s3 rom again no data how do i fix this?? I tried re-rooting it with odin and came back same result so then i have to go back to the s5 sensation so i have a working phone im stuck i dont know what to do..

i install a rom like this i wipe data/factory reset then wipe cache partition then wipe dalvik cache then install.

All advice help is welcome and appreciated
