how to fix ZTE zmax pro issues. I have Metro PCS.
1. Visual voicemail...there are 2 types. One comes from ZTE,the other from Metro. The Metro type is much better and is already included. Go to call settings /voicemail/visual voicemail and turn it off. Then activate the metro app. Some people get the Metro app and think the switch in call settings is for that. It's confusing to be sure.
2. MMS failures....first check that your APN is correct. Settings/cellular network/access point names. Go here https://bestmvno.com/apn-settings/metropcs-apn-settings/ . If it's wrong change it. In your texting app make any necessary changes . Then see if there is a setting for Stagefright..if so TURN IT OFF. This the main cause of failures.
3.Stock android (or other apps) has stopped. The problem is in the home screen. Download a launcher called Evie. Or try another one if you like but I can vouch for this one. If you want to recreate your homescreen take screenshots beforehand. Evie is very easy to use and has great settings and customization. You will not get themes,emojis etc that kids prefer. But it will get rid of the problems. Evie does not come with multiple blank screens. To add a screen drag an app to the right. You can switch off the options in the Stock android settings but the issues will return if it remains as your launcher.
I hope this info helps.
