Hello,
Using gelraen teardown I disassemble my Pro1. I remove dust and (thanks to @DieBruine) screw down with loctite all what I see with abnormally operating clearance.
I play a little with cameras stabilizer, everything looks normal. (My phone felt 2,50 m a month ago, and I only had VERY blurry pictures).
I reassemble, and test. Oh, pictures look blurry (a little). Then I disassemble the cameras plastic-glass behind, play a little with cameras stabilizer, reassemble glass. (see attached picture from service manual)
Surprise ! This camera works perfect, I can now taking pictures
