Samsung GT-I9515 seems to be a Galaxy S4 variant running Android 4.4.2 KitKat
The new handset’s model number, GT-I9515, is closely related to the model number of the original Samsung Galaxy S4 from last year (GT-I9500). Its features also seem to match the features of the old S4: 5-inch display with 1080 x 1920 pixels, and a 1.9GHz Snapdragon 600 processor with Adreno 320 GPU.
However, unlike the Galaxy S4, the GT-I9515 appears to run Android 4.4.2 KitKat. Dutch website GalaxyClub speculates that this could be a Galaxy S4 Neo. Samsung has already introduced a Galaxy Grand Neo and a Galaxy Note 3 Neo, so maybe it’s also readying an S4 Neo.
Unfortunately, Galaxy S4 Black Edition revealed last week (this one has the model number GT-I9505 and runs Jelly Bean).
Perhaps the GT-I9515 will be announced by Samsung later this month at MWC 2014. We’ll let you know if it happens.
