After T-Mobile, AT&T has also started rolling out an update for the LG G4 that is aimed at fixing the Stagefright exploit, which allows a hacker to take over any vulnerable Android phone by just sending an MMS message.
Sized at 46.7MB, the OTA update will leave your device with Android version 5.1 (build LMY47D) and software version number H81010l. The update is currently rolling out, so it may take some time before it hits your device. Meanwhile, if you're feeling impatient, you can also manually check for it by heading to your device's settings.
This comes just a few weeks after the Verizon variants of the #Samsung #Galaxy S6 and S6 edge smartphones started receiving the Android 5.1.1 update containing Stagefright patch.
