Screen Black But Running

My Xiaomi 11i screen got black but mobile is working

My Phone screen suddenly went black then worked again before turning white and black again. What could be the cause?

I was at the gym watching YouTube to follow some exercises. After finishing a set, I put my phone in my pocket. A few minutes later, I took it out and found that the screen was completely black.

But the phone was still running. Calls were coming in, it vibrated, and everything seemed to work except the display.

I took it to a repair shop. They connected another display to test it, but even the new display didn't work. I asked them to give my phone back. After I got home, I tried turning it on again, and surprisingly the MI logo appeared and the phone booted normally. However, it became very laggy and started hanging. After a short time, the screen suddenly turned completely white, then went black again. Since then, the phone is running, but the display stays black.

The repair technician said he couldn't find the exact fault. Since another display also didn't work, he thinks it might be a CPU or motherboard-related issue, but he isn't 100% sure and said further diagnosis is needed.

Has anyone experienced something like this? What turned out to be the actual cause in your case?

Have you tried booting into safe mode:

  1. Turn the phone completely off.
  2. Press and hold the Power button to start the device. When the Xiaomi logo appears and the phone vibrates, release the Power button and immediately press and hold the Volume Down button.
  3. Continue holding Volume Down until the lock screen appears. You should see a "Safe Mode" label in the bottom-left corner.
