completely agree. really disappointed in the brightness. holding side by side my 6S and it's no contest. the 6S is much brighter. the X by comparison is dim and dull. I turned 'TruTone' on and off and either setting is considerably darker and dimmer than the 6S. debating switching to a 7 if this is new normal.
I have a 6S and X. Unless yours is faulty, no way in any universe is the 6S brighter or is X dull.
I really don’t understand some of these posts.
