Officially that may be the case, but arace.tech claims to have 8GB versions in stock, and they seem to have been an official partner of Radxa in earlier launches.
If only developers/managers had their own sense of using the proper tools for the job instead of just swallowing everything the Big Tech shoves down their throat...
But when you see those job ads with all these "great new technologies" it's hard not to fall into the trap.
I've used to use an app (there are many) which measures angular velocity using accelerometer and displays RPM (you place the phone on the turntable). I can't see why would anyone need something other than that.
Complete noob here, but wouldn't the phones weight (especially with how big phones are nowadays) have a significant impact on the RPM by slowing it down?
It's very possible, increased weight will increase friction in the bearing. However my iphone SE weighs almost the same as a 12-inch record (150g). BUT it is also more difficult to place symmetrically on the turntable, which also could affect friction.
