Dealing with my USB sync problem, which seemed to start with an update of DJO around June 6, I'm wondering about going back to an earlier version for now. Questions -
1. How do I put an older version back on my phone?
2. How to I prevent it from automatically updating?

It was fine at DJO 4.4.2, build 1038


Samsung Galaxy S5, Android 6.0.1 (security patch level August 1, 2017)
DJO 4.4.6, build 1068; CL 7061.6
Win10 x64, Fall Creator/April 2018 update, v 1803; PalmDesktop 4.2

USB sync --- manual syncing, as needed
Not syncing to native Android calendar or contacts
