Same Model and Same Issue I am facing. I have done many experiments but i am unable to get rid of Chinese apps, except i force stop them.
Secondly I finally got able to install many of the apps using app search tool but still my Google Play Store is not working and i am again and again getting message that unfortunately Google play services stopped working. Hangout is unable to signin. Gmail, Maps, Youtube are working. Google Plus is not getting installed. Also there i couldn't find any option to have Google Contacts Sync in it.
If anyone can help to resolve this issue, i will be really grateful.
