My Samsung Galaxy S6 Lite hasn't given me any probs.
I'm no expert, but here's my general report.
I got the non-SIM card version, so it uses wifi from my other phone.
It's the 64GB (not 128GB) version. It will take a 64GB micro-SD. Again, I'm no expert, but if I wanted that I'd have a think about usability. Some Android versions leave the micro-SD fairly unusable for many purposes.
$499AUD at Officeworks.
DJI GO 4 and Litchi and a few other drone apps all install OK.
No compass, but seems to have everything else - GPS etc.
I'd like it brighter, but that goes for everything on a bright day.
Battery life - way longer than the drone's 3 batteries.
I'd like wireless charging, only has cable, which I always think is a vulnerability - water, dirt, rust, etc.
Weight:- I got a couple of adaptors to hold it on the controller. A fancy expensive adjustable aluminium one can't be tightened enough to hold the weight, but a cheap plastic one is just fine.
