HTC has already announced plans to bring Android L to its HTC One (M8) and older HTC One (M7) smartphones but it will update both to Android 4.4.4 before that. While HTC has yet to commit to the latest KitKat update, @Llabtoofer‘s latest HTC Software Updates shows that HTC is aiming to push the security-focused update in July or August.
Other devices set for an Android 4.4.4 update include the dual-DIM variant of the HTC One (M8), the HTC One mini 2 and the recently launched HTC One (E8). Those devices will likely see the update in the August to September time frame.
The Android 4.4.4 update is already landing on Nexus devices and, somewhat surprisingly, a number of Sony Xperia devices including the Xperia Z1.
