I Own a galaxy Note 8 I bought it in India SM-950F I have a very weird issue of my phone working perfectly fine when I restart it but as soon as the phone screen is off either automatically due to inactivity or I turn it off manually by pressing the power button it won't turn back on it just stays on black screen I can hear sounds of me touching randomly on-screen also I hear all notification but the screen remains black I have tried wiping cache I also reset everything no success.
Phone boots up in safe mode there are no apps installed phone also runs perfectly fine after a reset and If I don't turn off the screen it will continue to run perfectly fine it's just when I turn the screen off it won't go back to show the home screen until restarted again.
Also, the always-on display works fine Iris scanner works fine it gives me a sound notification that my phone is unlocked but I can't see anything due to screen being black.
Thank you so much for reaching out!
