In front of me is HTC desire21 pro and let me show you how to change video resolution on this device, so at first just open the camera up. Then let me go back then move to video mode and now select settings, and here this first icon is for resolution, so just tap on it on this first one to change the resolution so smoothly by tapping you can change it and then leave it once you apply the one that you would like to record your videos in. So this is it. That would be all thank you for watching. Please subscribe our channel and leave the thumbs up.
