Low resolution of video call. lack of focus on rea...

Question

I've got HTC One m7 which has both cameras capable of at least 720p yet maximum resolution I got using front facing camera was 7**x4** so less than 720p.
another Problem I noticed was lack of focus using rear camera, at all distances the picture was blurry, out of focus. 
I'm using 5GHz WiFi on virgin's 50Mbps. 
does Skype for android even support 720p video calls and if not his is it even possible?

I've checked it with my friend. There is no problem but still I haven't checked if it still exists while video call with my other friend that I'm having this problem with. Basic
