Maybe substantially increase C1706 from 10u to say 470u switch type?
Anyway i wondered whether U1703 shouldn't operate PWM-mode 5->3.6V stepdown 
converter - so there's some coil and a freeweel schottky-diode missing for 
this operation mode. Probably 50606 doesn't support it at all, so just a nice 
idea.

Anyway i guess for 50633 (GTA02) this is completely different
