Hello people!

Sorry for creating a new thread but I have some important questions, and I hope that somebody can help me out with these.

I have recently purchased an Intex Aquafish. It is an excellent device, and SFOS is simply brilliant.
How can I trick my Intex to think it's Jolla C (but a total noob guide, please)?
Can you recommend some of the best native apps?
What is the best store for Android apps?
Are there any apps for syncing my Xiaomi Mi Band 2 with the Intex?

Tnx in advance and sorry for my poor English skills
