Voice mode on app/mobile

Two separate questions about same issue:

Ive created several personal contexes instructing specific keep notes das data structures for gemini to write to depending on subject. On text chatbot browser UI it works perfectly. But....

1-Voice mode inside gemini mobile app seems to ignore personal contexes. Im doing something wrong or is it current state of funcionality?

2-Android voice assistant (ok google) even set up to use gemini, when activated uses "dumb" (haha) regular assistant instead of gemini. All the configs menus on android are very confusing and cluttered. There is any hidden config to do this correctly?

Thanks.
