Thanks for your reasons for buying the Yotaphone 2.
Because the Yotaphone 2 prices seem to be stabilizing at under US$130 at five different sellers, as opposed to those low prices being a special one-time sale, you might want to try flashing your phone now, and only buy another if you brick it.
I've been updating the
Yotaphone 2 pricing post on page 4 (post #58) of this thread since I originally made that post, and the five sellers are all selling for less than US$130. Gearbest ended their $120 sale when the last of the allotted units was sold, and the price went up to $157 for a day or two, but now it's back to $120.
P.S. I bought one also.
