Battery charging got flaky after the update- need to reboot in order for plugged-in unit to show evidence of charging. Google Voice had to be retrained as well. Hopefully next update will stabilize matters.
I use Idol 3 (5.5") with no problems. Annoyed by the fact a Metro employee must activate it, so self-serve options to activate don't exist. Otherwise it performs well on the Metro/T-Mobile network.
