I sprayed screen cleaner on my Vivo V9 screen and wiped it with a microfiber cloth. The next day, it started showing a ghost effect, then vertical lines, and eventually change its color. Which one should i choose: sending it to a technician for repair or buying a new Redmi Note 14 5G (within my budget)? I'm worried the technician might do something suspicious to my Vivo V9 during repair. I also can't use CIMB OCTO because my Vivo V9 doesn't support Android 10 and above. Should i switch to another bank like Maybank without buying new phone?
