T-Mobile HTC One M9 getting September security update


After receiving an August security patch earlier this month, T-Mobile’s HTC One M9 is now getting another update.

TmoNews reader and HTC One M9 owner Kevin says that his phone got a 355.44MB software update today. The update brings the One M9 to version 3.39.531.21 and includes the September 1 security patches.


T-Mobile hasn’t updated its support page with info on this update — or the last update, for that matter — so it’s unclear if there are any other tweaks included.

It’s kind of strange to see the HTC One M9 get two security updates in one month after it went months without an update before these, but hey, this is exciting for anyone using a One M9. If you’ve got a One M9 and haven’t yet updated, you can check for this update by going into Settings > About > Software update > Check Now.

Thanks, Kevin!
