One of the biggest complaints about smartphone gimbals, particularly with the size of today’s phones is that they typically attach via a springy “claw” type mechanism. This can be troublesome with huge phones, often pressing the buttons on the side of your phone when you least want them to. You can shift the phone over, of course, but then it’s all out of balance, stressing the motors and battery.
A new leak of what appears to be the DJI Osmo Mobile 4 seems to fix that, though, by using magnets to hold your phone safely onto the gimbal. This should help to make things lighter, as well as avoiding the button-pushing balancing issue.
