User opinions and reviews

Exactly! Mine too! Do not update if you don't wanna waste your money.

If I update my phone...its touch will not work anymore.because it is an aftermarket screen.🙃

What is the frustration about? Mine is running on the latest version with October patch & runs butter smooth without any hiccups.
