cytrus224V30 could do 4k 60 with EIS?
There for sure is some problem. Battery is 28 degrees while idle when room temperature is 22. Asus should try tuning frequency/voltage tables of the chip and check why phone is so warm even when idling&locked. I have lg v30 and its not having any problems recording 4k footage with OIS while ZF8 does(overheating)
