There are coloured stains or tint on the display, what can I do? (Android 9 or lower)

Information / Solution

Try these methods one after the other. Verify whether the problem was solved after each method, before trying the next one.

• Turn off your device and then turn it back on.
• Make sure that the perceived stains are not caused by a protective screen film or case used together with the device. Remove any such accessories to make sure that there are stains on the display.
• Use the Xperia Tests feature in the Support app to find out if the stains are the result of one or more missing or odd-coloured pixels. 
• Check if there is a software update available for your Xperia™ device,  find and tap Settings → System or About phone → Software update  → SYSTEM.
• Perform a factory data reset. Note! Back up all personal data before performing a reset. All data in the internal memory is overwritten during a factory data reset. Content on an external SD card is kept.
• If coloured stains or tint still appear, contact us.
