In marshmallow (6.0.1) Yota has include a new feature for the yotaphone 2, an easy way to change the animation for the smile e-ink when you take a photograph.
So I upload some custom shutters send by an user on the spanish Telegram Yota group, simples but very effectives. All credits goes for Francesc.
Very easy to change on your yota: Go to Adjustments / Camera & Smile
Chose custom shutters and upload the 2 jpg in order as Frame 1 and 2.
