A quick heads up for owners of T-Mobile’s Samsung Galaxy S3 that a small software update should be heading your way. It keeps things on Android 4.3 Jelly Bean and mainly includes fixes. Android Central Forums member jazman_777 does report that it seems to pre-load the Google Drive app on the phone.
The update is available either through OTA or through Samsung Kies, and you’ll find more at the source link below.
