Ok so this is very annoying , all apps and systems is upto date. i usually use google tv to play my purchases but on this phone the video playback lags and is not smooth it is choppy maybe 20 fps or something thats on all movies. Also i have encountered this issue on amazon prime and other video playback. Also the camera is very slow in filming , or even 4k filming is the worst . Too slow rendering. I was filming a video and the light kept getting bright and high exposure , out of focus i had to scrap the video. When playing the video that i have recorded its also plays choppy. They really need to put in a snapdragon 700 series in this its too underpowered or at least update these fixes.
