Re: T-Mobile Galaxy S4: Pick up calls and auto hang up problem. WORKAROUND
*android s4 problem, call ends call is hanged up after being answered*
Scenario
Any Call triggers a CIRCLE type input. After swiping to the right the call does not begin immediately, instead, it opens up a HORIZONTAL BAR type of swipe. Instinctively, you will try to swipe right a second time to answer your call.
This causes the call to be answered, remain open for about 3 seconds, then hangup.
Problem
There is a conflict overlap with the phonecall UI. By accepting the call in two different UI's, the calls is terminated shortly after being picked up.
WORKAROUND:
When receiving an incoming call, answer it normally with the CIRCLE-type input by swiping right.
If the Touchwiz horizontal type screen is shown, ignore it, do not interact with it.
The call will take around 3 seconds to begin, but once it does, all will be ok and the auto-hangup will not take place.
CAUSE:
Unknown. But started to happen since June/July 2014.
Fix/solution
Not determined yet.
