Firstly, I would like to share with you the wallpaper HTC One M9, everything can be found here – it will be useful for any smartphone. I would like to note that the images chosen by the designers are simple, comfortable, cozy and very simple (but this simplicity is worth a lot).
Secondly, in HTC we made an online theme builder for M9, it is located here, you need an account HTC to log in.
You can choose any wallpaper as a basis, including upload your own, choose icons, sound, font, save it to your smartphone or share it with other Sense 7 users. If you need more features, there is a Pro version. It is gratifying that HTC are preparing so well for the release of a new smartphone, we are waiting for the M9 on store shelves.
