I've started noticing that my phone's screen flickers intermittently, and sometimes vertical lines appear across it. It's distracting and makes it hard to read.

If your phone supports wireless charging, try using a wireless charger to bypass the physical port.

Carefully clean the charging port with a soft brush or compressed air to remove any debris.

Inspect the phone for any visible signs of damage, such as a swollen battery or cracked screen, which might indicate internal issues.

Take the phone to a qualified repair technician for diagnosis and potential component replacement.

If a force restart doesn't work, try booting into recovery mode to clear the cache or perform a factory reset (this will erase data).

Research the specific button combination for your phone model to force a restart (e.g., holding power and volume down buttons).

A faulty charger or cable might be preventing the phone from charging properly.

Connect the phone to a known working charger and outlet for at least 30-60 minutes. Use the original charger if possible.

Check the permissions granted to installed apps and revoke any that seem unnecessary or suspicious.

Install and run a reputable antivirus/anti-malware scanner on your tablet to check for and remove any threats.
