I sort of just noticed that when I place my iPhone 7+ onto the gimabal and then calibrate, the phone isn't level.  Now its not bad, but when I use a level app or Procam 4 as an example, I have to adjust the gimal manually.  Is this what others tend to do also, and do you guy's/gal's calibrate the unit everytime?  I do have the latest firmware also, which I installed yesterday.  
Thanks

The calibration doesn't have to be 100% level. It's OK to have a 20 degree difference

Thanks!  this helps as I can now just manually level the gimbal.  Though maybe the unit was defective

20 degrees? That is quite a lot.  +/- 10 Degrees would be more within the margin of acceptable.
