My phone, which I think is a Redmi S10, has developed a large blue spot in one corner of the display. I'm wondering whether this means the screen pixels are failing or if the battery might be swelling and pressing against the screen. What should I check, and is it safe to keep using the phone?

A blue spot can come from display damage or pressure beneath the screen, but it’s difficult to identify the cause without a clear photo. Check whether the back cover or screen is lifting, the phone is unusually warm, or the battery is draining or swelling. If you notice any of those signs, stop charging and using it, and have the battery inspected or replaced safely. Otherwise, a repair shop can test whether the display itself needs replacement.
