It’s totally upto you whether you consider the HTC One or the SAMSUNG Galaxy S4 as the best phone in the world, but in any case, you can enjoy AOKP on either of them now.
The international HTC One (m7) and the T-Mobile Galaxy S4 (jfltetmo) both have been added to the AOKP roster, and in fact, nightlies are already out for them. Head over to the devices section to download them and get Unicorns prancing around on your favourite 1080p screen.
Please note that questions about other carrier versions of these devices are pointless to ask. They shall be added as and when some of our Team Kang members get to test them out, or Khas Mek invites some device maintainers on board ;)
P.S. Those who think their kitchen toaster is the best phone in the world, rest assured, we are working on it. Expect support soon.
