CSG app store
1) Go here on your device:
and install (you may need to allow installing from unknown sources).
2) Run the Aptoide app (you can ignore the social media account sign ups).
3) Select "Stores" tab and then select "Follow"
4) type in CSG and hit enter
You can now browse the store and find things like the GAB app which Google kicked out of the Play store (hmmmmm....)
