Hi this is actually my first post so hope you guys can help me out. Have an Xperia Pro (not mini). Been working really well since I bought it about a month ago. However have now encountered a wierd problem with the screen. When I turn on Waze GPS app - the screen goes mental and constantly flickers (almost blinking you could say) and I cant press anything on the screen - only pressing the home button (physical button) lets me get out of the app. This strangely doesnt happen with any other app except for Voxer (which i dont care for much anyway was just trying it out). Running stock gingerbread btw. Can you guys help please? FYI I have tried out the following steps: 1. Tried with changing brightness settings - tried it on auto, low and high and problem persisting. 2. tried restarting phone few times - no change. 3. tried uninstalling waze and reinstalling - no change. Tried with data clearing too - no change. 4. Problem persisting when app is stored on phone or on sd card. Is this a hardware or software issue? Its wierd because the problem only seems to exist on Waze (and Voxer). Help please! Im in India - they normally dont replace the phone in warranty they will repair it only which could take ages!
