LG G6 on AT&T: What the update landscape looks like
The LG G6 launched on AT&T in 2017 and received official support through multiple Android versions and security patches. On AT&T, the G6 moved from Android 7.x at launch to Android 8.0 O updates att&nbs p>The device also carries a device-specific firmware model number, which can affect availability of over-the-air (OTA) updates and any carrier modifications or tests required before rollout.
Android version history and upgrade path
Initial launch software and major upgrades
At launch, LG G6 on AT&T shipped with Android 7.x and later qualified for Android 8.0. Because the device uses a carrier-specific build, updates must be certified by AT&T for compatibility with their network and services. After Android 8, the device was not positioned for later major Android upgrades by either LG or AT&T, which is common for non-flagship carrier devices.
Feature and security patch timeline
Carrier models typically receive monthly security patches for a defined period, but major OS bumps are uncommon once a device moves past its initial supported window. On AT&T, relevant milestones align with when the device was active in the carrier portfolio.
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Model/firmware (AT&T) | LS790 or similar carrier-specific variant | Device specifications and regulatory filings |
| Initial Android version (AT&T) | Android 7.x at launch | Carrier launch documentation |
| Last major OS update | Android 8.0 O on AT&T | Changelog and rollout notes |
| Security patch cadence (typical) | Monthly patches while supported; no public fixed end date | Carrier practice and historical announcements |
The exact model number on AT&T (such as LS790) links to carrier certification records, which governs when and if OTA updates are delivered to consumer devices.
How to check whether your AT&T LG G6 is up to date
To verify current software on your device:
- On the phone, open Settings, tap About phone, then Software information to see the Android version and security patch level.
- Check for an Over-the-air update manually by selecting Software update in Settings, or on the device’s update screen if available.
- Compare your build number or security patch date with official LG and AT&T release notes for your specific model (LS790).
What to expect going forward
LG G6 no longer receives new major Android version upgrades on AT&T. Updates are typically limited to critical security patches only when a carrier chooses to continue providing them. You can still maintain device security with monthly patches, but functionality and app compatibility will increasingly require newer hardware over time.
Options if you need more support or newer software
If you need updated features or prolonged security support, options include using the device as a secondary device, exploring custom ROM availability at your own risk, or upgrading to a newer device supported by both Google and your carrier. Check with AT&T directly about any remaining firmware versions for your IMEI if you’re troubleshooting update availability.
For most users, planning a migration path off the LG G6 will deliver better long-term compatibility and security than waiting for new carrier-driven major updates.
