The Android 6.0 Marshmallow update has finally come to LG G4 on US Cellular, weeks after it was released in South Korea and Europe. Only the Sprint version of the device has received the firmware in the US until now.

US Cellular models of LG G4 should get the Android 6.0 Marshmallow OTA (over-the-air) update in the next few days. The update started on Monday, according to DroidLife. The report went on to say LG G4 on US Cellular is model US-991 and the update is rolled out as US99120b.
