After day 1 with the 8X I am mostly happy with it. The keyboard is my biggest problem since I am coming off Swiftkey Flow and wish the 8X had it. But it's prediction is getting better. Anyway, I use my phone a lot for reading and I often do that in bed just before sleeping, using Kindle. I'd love a rotation lock to keep it in portrait, but I can't seem to find one. Is there one? Searching the forum for rotation doesn't bring up anything.
