Oppo F3 was released back in 2017 running a MT6750T cpu. Initially it was released with android marshmallow but an official android nougat was released back in 2018 (which is a bit laggy with no updates in foreseeable future). And it seems like that’s the end of it for the phone. 
It’s not a very popular device but it has a fair number of users. It’s kind of disappointing that there aren’t a lot of options to upgrade this phone. It would be nice to see it be revived for longer use.
