Tinatywalker, I can understand how not being able to access your screen while you're on a call can be upsetting. You mentioned you've been dealing with this for over one and a half years, and we want to help! Google has identified this as a known issue. Please ensure your device software is up to date using the steps here: http://spr.ly/6605E29Zf Next, remove any existing screen protectors from your device and wipe your screen. This can cause your proximity sensor to believe your device is being held to your ear. Does this help?
