Random Crashes, Freezing or Reboots

Lately I have seen some ocassional behavior such as random crashing, freezing or spontaneous reboots mid-game. I wanted to see if anyone else experienced this and if they know what game they were playing at the time or any other details (ie brightness, power settings etc).

Just now I was playing Wario Ware Inc with mGBA, about 30% brightness, balanced power setting and it suddenly rebooted itself.

I haven´t experienced that, I don´t play that much but I have it in server mode power settings and have it on for hour with usb eth

It seems to be related to power supply, please check the power cable or try to use USB power, which helps us to locate the issue, thank you!
