How this guide was reviewed
The workflow was reviewed against hands-on phone-repair and device-inspection experience, then checked against the limits of current browser access. Browser observations, user-confirmed checks, and items that require operating-system, carrier, manufacturer, or physical inspection remain separate.
Persistent images can have different causes
A faint keyboard, status bar, navigation element, or app outline that remains visible can be temporary image retention or longer-term OLED wear. One quick glance at the home screen is not enough to tell the difference.
Use solid colors and neutral gray backgrounds so the pattern is easier to see.
Check several brightness levels
Some display defects are more obvious at low brightness, while others appear at high brightness. Test a moderate level first, then compare lower and higher levels without staring at a maximum-brightness white screen for an extended period.
Also disable automatic brightness temporarily if it keeps changing the display during the inspection.
Use multiple colors and gray
White and gray can reveal tint and uniformity issues. Red, green, and blue screens can make pixel defects or uneven wear easier to identify. Black can reveal light leakage on LCDs and abnormal glowing areas on OLED panels.
No single color is enough for a complete visual check.
Temporary retention should change over time
If the faint image fades after normal mixed content, it behaves more like temporary retention. If the same pattern remains consistently visible across sessions and backgrounds, permanent wear becomes more plausible.
A browser can help display the test patterns, but the judgment is visual and should remain labeled as user-confirmed.
Continue the inspection
Keep testing with a second signal.
A useful diagnosis usually comes from comparing more than one symptom. These related guides can help you build a fuller picture.
