I couldn’t find a recent or specific “LG G3 update for U.S. Cellular” post because . The last official software update for the U.S. Cellular variant (model LGUS990 ) was likely Android 5.0 Lollipop or 5.1 , with security patches ending around 2016 .

If you’re looking for older discussions, XDA Developers forums or U.S. Cellular’s community page may still have archived posts. Searching for “LG G3 US990 update” on XDA or Reddit’s r/LGG3 might yield historical threads.

If you have a specific issue (e.g., “checking for updates” stuck or a custom ROM), let me know and I can help troubleshoot.
