HTC in a tweet on Monday, announced that 60fps video recording is coming to their latest flagship, the U11. They intend to roll out this feature through software over a couple of months.

According to HTC, the months-long period is because of multiple SKUs for the devices around the world that need approval.
The caveat here is that, the 60fps update will only be for 1080p video but not 4K. This flaw is just like its competitors’ ;The Galaxy S8 and LG G6.
