Well I have two possibles paths in mind :
- install Open GApps. I can’t give you any clue on this because I try to live without google… but other users here can point to the right documentation ;
- try to make UnifiedNlp work in your system. You can have a look here, but the last time I recommand a forum user to try this workaround he reported to have messed up his phone, so if you choose to give it a shot, please be careful
… and please note that I will decline any responsability if you come into troubles .
To be honest I really think that the fix will come soon with the next release, so the best solution IMHO is to wait for it… but I’m in no rush on this feature.
