Just about a month ago, we learned of an annoying problem that was affecting some owners of the HTC One S on T-Mobile, where trying to take advantage of the carrier’s WiFi calling option was tearing through the phone’s battery capacity at an accelerated rate. The solution T-Mobile offered at the time, of just leaving your phone plugged-in, wasn’t very satisfying, so we were hoping to see it make good on its promise to later address the issue via software update. That update is now finally about to land, with the carrier advising One S owners to expect it to start arriving on June 4.
The update keeps the phone on Android 4.0.4 but delivers a whole bunch of bugfixes and tweaks. Besides the WiFi calling issue, the software will address problems maintaining a strong lock on cell towers, hopefully resulting in more consistent signal strength. The phone’s camera should now perform a little more reliably, and when using the newly-fixed WiFi calling feature, voicemails should now display correctly.
The update will be going out OTA from June 4 through July 7; starting on June 4, you’ll also be able to pull it down and install manually.
