Not true - I've been using using a $100 Motorola G6 for the past 8 months with no issue. I bought it as a "temporary" replacement when I cracked the screen on my $399 X4 which I had used for 2 years with no issue (silly me, with a price that low I decided to self-insure). I ended up using the G6 as my primary phone because it's pretty good phone and does everything a modern flagship can but with expandable storage via microSD - the only downside is that the camera doesn't take amazing pictures
