This phone has screen lift from the top right corner. And the black dot is obviously the indicator of screen damage from a hit. Aside from the screen, the phone is literally perfect. Once you fix the screen, this phone will be like new. everything on this phone works. The phone has been factory reset and previously it was unlocked, but the phone sort of defaulted to T-Mobile again so it’s possible that it’s still unlocked but prefers T-Mobile or it’s also possible that it’s gone back to the T-Mobile lock. I’m selling because I didn’t find the fix worth it. I just bought another phone. Any questions feel free to reach out.
