Black screen but the top bar and back buttons are visble

Hi I've been experiencing this for almost 2 days already I've tried to reset, format same thing that I did with my memory card. I also noticed  it took time to open pressing the power button won't work sometimes.

Hi @Alexene and welcome to the community.

I'm sorry to hear this. I recommend that you temporarily remove any SD and SIM card from your device to see if they may be the cause of this behavior.

I would also recommend that you reboot your device to safe mode to see if this behavior is caused by one of your downloaded apps as these will be temporarily disabled in this mode.

If you are still experiencing the same behavior I'd recommend that you perform a software repair using Xperia Companion to rule out that anything software related is causing this behavior.

Let me know how it goes.
