Vivo x3s (Chinese phone) Google play doesn't open and no error

[Dunno7]

I had to flash the firmware cos the phone was stuck at the loading screen. When I bought the phone I just simply uploaded google play apk and installed it. Now it installs and when I tap on it it flashed for sec and nothing happens. I've tried cleaning the caches and resenting to the factory settings to no avail
