My Xiaomi has 3 red smudge spots just appearded on the screen?

Hi Matt,

before → If the mobile phone is still in warranty, ask the dealer.

phone has not been dropped, exposed to the sun, water on any pressure.

If not, it can be manufactoring issue, it’s happening, but in a lot of case, this is issue made by the user. There are a lot of things which can influence the display, but about me, it’s fault from production. The mobile phone can’t be on the sun for a long time, or in the very hot spot like a car. In these case, 80% of mobile phone will turn of or disable some freatures and send message to user with a request about cooling.

So my theory is the heat.
