Axios reports that AT&t, Verizon, T-Mob and TCL have all announced they will stop calling their customers with an app crash or “sick” android 18 app.

These apps include a new app for T-mobile customers called Smart Alerts that will notify users if they’re receiving text messages and alerts on the condition they turn on “smart alerts” and listen for “sudden alarms.”

These apps also have an “S.O.S.” alert feature that will send users a text or email if they have an alarm that sounds too loud or if they hear a message that’s too fast.

This would be especially annoying if users are listening to music, but aren’t in their homes.

T-Mobile and Verizon are calling this “a new generation of mobile technology” that is “much more reliable” than the apps they are using to call customers, but will not stop them from calling users.

Verizon also announced a new phone app called Caller Alert that uses Android’s Voice Recognition feature to identify the phone on the other end.

T-Mo and Verizon say that the apps will not be impacted by this update.

AT&ts is saying it has already stopped calling customers with “sloppy” apps, which are not compatible with Android 18, but the company said it was investigating this as a new “generation of mobile technologies” and would not be changing how it handles Android 18 apps.
