Wherever I turn on my screen, white lines appear for a second before the lock screen loads. Every time it happens Im afraid the screen won't load at all. This same thing happened on my first Charge, so I am wondering if a) this is normal or b) my non-stock Samsung 1500mah battery is the culprit. Please help a beginner out I am worried sick that I received yet another defective phone. Thank you for your time.
