I have a Huawei p20 Lite for about 2 months and it is a good phone, but unfortunately my camera breaks a video very often, sometimes after 3 seconds, but at the latest after 2 minutes. Space is still there enough (over 32 GB) and I have restarted already. What could it be?
Are you recording on SD card? Then maybe it's just too lame or broken.
Software error. Get it repaired. My p20lite works fine, even with longer shots
Thanks for the tip, my SD card was really pretty full and old, I've switched it to internal memory and now the recording is already over 2 minutes without problems
