agreed

I just bought a Meizu M7 pro and after I configured everything (it took more than one hour) I am not able to change settings cause the app crashes all the time. I don't want to restore factory configuration cause it took so long to have the phone configured, I cannot believe nobody has fixed this huge problem yet.

La solucion es facil, navega en la play store busca en tus aplicaciones instaladas encuenntra la app de google esa que parece que no sirve para nada, la desinstalas si no puedes como en muchos de los casos desintalas las actualizaciones luego la vuelves a activar y listo, Podras denuevo entrar a las configuraciones

1 - buscar la app google ( si no funciona el teclado navega en la play store en la pestada de aplicaciones instaladas)
2 - desinstalar actalizaciones de app google
3 - actualizar la app

Hey guys try to use the Hidden Settings app, it opens the settings tabs and you can manage your phone. My issue was about the language when I'm changing it, settings stop working, changing it back through the Hidden Settings app fixes the problem.
Hope it will help someone.

Yes me too

I solved through TitaniumBackup, just search for "Settings" and select wipe data.

This helped me, also, if you want to use actual settings, just change your language to Englsih
