HTC may release its next flagship phone as soon as next month. Expected to be called the HTC U12, the phone would serve as a follow-up to the U11, and could be released some time in April, according to mobile tipster Llabtoofer.  

In addition to a possible availability date, a list of potential specs and features were leaked. We could not independently verify these claims -- HTC did not immediately respond to a request for comment -- so take this information with a grain of salt.
