Since December I have been experiencing freezing and slowness issue on my iPhone while editing Instagram reels or video.Sometimes it crashes with heat even though I have enough Ram and disk space .Looks like others are also facing the same issue .Is it not worth buying an iPhone that too for video editing ,it is having a enough capacity /resources to deal with such tasks . .When will it be fixed .
