Frequently asked questions
Are display lines repairable or do I need a new screen?
If the OLED panel itself has impact damage (most cases), the panel must be replaced — lines on OLED indicate dead pixels that can't be "reset." If the cause is a loose display flex cable (about 15% of cases), we can fix it without replacing the panel — cheaper repair.
How fast do display lines spread?
OLED panel damage typically spreads — lines that started as one or two columns can become a half-screen blackout within a few weeks of normal use. Earlier replacement is cheaper because secondary damage to the digitizer is avoided.
Will I lose data when the screen is replaced?
No — display replacement does not touch the storage chip. All your photos, contacts, apps, and settings are exactly where you left them. We test the phone after repair so you can confirm before we leave.
