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

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

Yes me too

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.

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

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.

agreed

If they don't fix it within the next few days I am changing companies and buying a new phone from any other company other than Meizu.

Same problem. No way to open the settings since the last update. Why don't they fix this?

Yes after the update the setting crashes. Meziu flyme OS really sucks. This is my first and last phone from Meizu.
I even have the problem where the network is unable to detect 4G it works only on 2G. Xiaomi is way better.Wrong choice.
