We recently got a sneak peak at Samsung's roadmap and it brought to light certain handsets, one of them being the G750 Galaxy K Mega.
The Samsung SM-G750 self-identifies as "Mega 2." @evleaks (@evleaks) May 15, 2014
According to the latest bit of insider information, courtesy of evleaks, the phone will be called Galaxy Mega 2. Previously, the phone was identified by the name Galaxy S5 Neo.
Not much is known about this phone, other than it has a 6.0-inch display with 1280x720 resolution and will likely replace last year's Galaxy Mega.
We'll let you know if something more should come up on this...
