The UAP (user agent profile) of a yet unofficial Samsung smartphone has been uploaded to the company's servers. The device called SM-G750A, which suggests it is most probably headed to AT&T.
According to the information we were able to extract from the UAP, the G750 packs a 720p display of unknown size and runs on a quad-core 2.3GHz processor, which could only mean Snapdragon 800 chipset.
The Android version ticking inside the G750 is 4.3 Jelly Bean, but this could easily change in time for the release.
There is no more information on the G750. It could be the US model name for the rumored Galaxy S5 Neo, or it could be even the purported Galaxy S5 mini. Hopefully the official announcement isn't that far away.
