ZTE ZMax Pro Z981 New Android OS update: May 2017
I got the new update this Saturday (May 20th,2017) and updated my phone.
So far I have one problem. When I get a text message my notifier says I have a text message but it doesn't show up on my screen as having any messages.
How do I either fix it or go back to the previous version?
Is dit een goede vraag?
