Hi,

I often use facetime audio in speaker mode. Sometimes I forget to lock my screen, because autolock doesn't work during a call (right?). (Between: this also uses a lot more battery power)
Sometimes these calls can take about 1-3 hours.

One problem of OLED-displays is that pictures can burn in when things are displayed too long.

So when I forget to lock the screen and it shows the callers name on my display for 1-3 hours, could there be a problem with burned-in pixels?
And is there a way to prevent this (besides not forgetting to lock it manually)? Maybe there is a way to enable autolock for calls also?

Thank you!
