Sprint kicks off LG G6 Android 8.0 Oreo rollout
If you own the LG G6 with model number LS993, you qualify for this sizable update. Apparently, Sprint's Android 8.0 Ore update for the LG G6 weighs in at 1.8GB, so you'll want to make sure that you have enough storage prior to downloading the update.
The very succinct changelog mentions the update “optimizes performance” and adds the May security patch, besides updating the operating system to Android 8.0 Oreo.
Two other US carriers, AT&T and T-Mobile, have yet to release Android 8.0 Oreo updates for the LG G6, but that should happen any moment now.
