Sony’s upcoming Xperia X may suffer from camera overheating issues. The device features a 23MP f/2.0 that’s capable of recording video at 1080p at either 30fps or 60fps. Reports have now surfaced that overheating issues may be causing the camera to malfunction within minutes.

A reviewer, Damir Franc, posted a video on YouTube (it’s since been unlisted) where he proved that the Sony Xperia X’s camera would consistently get jittery after a few minutes of recording. Android Authority tested these claims on their own review unit and discovered a “some functions disabled by temperature rise” error after a few minutes of recording. However, they could continue recording at least another 30 minutes without issues.
