HTC’s Android L update schedule has been leaked and it indicates that the first updates will land by the end of the year.
One M8 and One M7 Google Play Edition devices should get the update, with evaluation starting in October. Android L with Sense 6.0 should eventually come to the One (M7 and M8), One Mini 2, One Mini M4, One Dual Sim, One E8, Butterfly S, Desire 817 and Desire 610.
Some older devices are off the list, like the good old One X and first-gen Butterfly. However, most HTC phones launched over the last two years will get the update, according to llabtoofer.com.
In essence, all HTC phones launched in 2013 and 2014 should get Android L, but we’re in for a relatively long wait.
