Does anyone know why is this happening and how can I fix it? I was just scrolling through instagram and the screen suddenly became to have a green tone, I tried to restart it but nothing happened.
@Members_4KB1Lq9: Please can you try heading to Settings > Display > Eye Comfort Shield, and toggle this option off if it's active. Also, head to Settings > Accessibility > Visibility Enhancements > Colour Correction, and toggle this off if applicable.
There appears to be a significant amount of damage to the screen of your Galaxy A21, which may be causing an unforeseen defect. If the issue persists, I recommend reaching out to our Help Desk to arrange for the device to be inspected and repaired, so it can be brought back to it's warranty specifications. Please be aware that physical damage is not covered by our standard warranty, therefore a charge will be applicable to cover the cost of the service.
