Problem with screen flashing black
Hey everyone Ill try to be brief but I have recently discovered a weird issue with my Galaxy S2 LTE on Rogers Wireless...Whenever it changes network modes (ex: driving in a car as it switches between EDGE, 4G, and LTE based on coverage in area) it causes the screen to go black for a second. It happens while in any app, like if I'm browsing, the screen will flash black for about 1 second then back to whatever I was viewing as it switches networks. If the phone is on the home screen and switches network modes, the home screen will rotate to landscape mode and appear to be zoomed in and then go black before switching back to portrait - which is very weird because stock touchwhiz does not rotate home screens.
I have done a factory reset and gyro calibration and still have same issue. If the phone isn't switching network modes it works 100%.
I'm running ICS 4.04. Phone is not rooted.
PS - this issue is especially annoying because at my house my phone gets weak LTE signal so it switches between 4G and LTE frequently. Yes I can prevent this by changing the network settings but I find this problem troubling; is it hardware or software???
