HTC has detailed an over-the-air update for the Sprint version of the One M7 that rolls out what the company refers to as "Google security fixes." This is vague in the usual carrier-provided-update-way, but folks over in the Sprint Community have reported some more specific changes. Users who install this update should no longer see the annoying "Smith Disabled" notification that appears after every reboot. The default flashlight app has apparently also been replaced by an LED flash app.
The OTA bumps users up to software version 5.05.651.2.
If you rather not wait for the update to arrive over-the-air, prefer to install things manually, or have tinkered with your device and just need to get your hands on the latest RUU, HTC has provided the full 1.5GB at the first source link below. Instructions are available at the bottom of the page.
