If you have the HTC One M9 on either AT&T or T-Mobile, you should be able to expect the update to make its way to you today, if it hasn’t already. If you have yet to receive the notification that an update is waiting for you, fret not as we expect that the update is being rolled out in stages and should make its way onto your phone eventually.
With the update, HTC has brought about improvements to the handset’s camera which is actually a pretty obvious improvement, so if you did not particularly fancy the HTC One M9’s camera before, hopefully the update has improved it to your liking. According to the changelog, there have also been improvements made to the thermals of the phone, along with your usual assortment of bug fixes and improvements across the board. The update should bring your software number to 1.32.502.31, so if you already have that version you should be good.
