My phone no longer wants to unlock properly. I unfold it and the screen stays black; i use biometrics to open, I hear the unlock sound, but screen stays black; i relocked using button, hear the noise, use the button to unlock, screen finally lights up and unlocks - BUT this is only if i lock the phone with the button before folding it. If I fold it while unlocked, the screen won't turn on. I can hear the locking/unlocking sounds but its still black. I have to restart it twice before the screen comes on, and sometimes that only works if it's on charge. This is a new issue that has been happening for roughly 2 weeks now and may have something to do with the new update, as it was fine beofre then. Samsung, can you please fix this? It's definitely a software issue, not a hardware one, as once the screen come on I can see that it responded to any clicks I did while the screen was black.
