T-Mobile HTC One M9 gets Android 5.1 Lollipop

Most HTC One M9 flagships in use across the United States already received Android 5.1 Lollipop, including those on Sprint and AT&T, not to mention the developer version. Unfortunately, T-Mobile did not update the HTC One M9 smartphones on its network until yesterday when the new Android 5.1 Lollipop-based firmware began to roll out.

According to the official support page on T-Mobile's website, this software update for HTC One M9 carries version number 2.7.531.6, has 833 MB in size, and comes with the following features and tweaks:

• built-in anti-theft functionality
• Google Wallet
• battery improvements
• Android 5.1 Lollipop platform upgrade (all the tweaks and fixes of the stock 5.1 release, including stronger WiFi and improved notification options)

To apply the OTA update, the handset must be connected to a WiFi network and have at least 50 percent battery left, as well as enough internal space to accommodate the new firmware. Since the update was unleashed yesterday, it may take some time until it reaches all HTC One M9 handsets on T-Mobile, so those in a hurry can check for it manually, as usual.
