Samsung launched a new variant of the Galaxy S5 over two years ago called the Galaxy S5 Neo. It had a different processor and support for LTE-A. The Galaxy S5 Neo featured a 5.1-inch 1920×1020 pixel resolution display with a 1.6GHz octa-core Exynos 7580 processor. The handset featured 2GB of RAM and 16GB of storage, a 2,800mAh battery and a 16-megapixel rear camera.
The company doesn't appear to have ceased firmware development for this device as just three months ago, a new firmware update was released for the Galaxy S5 Neo which brought the March security patch for this handset, even though countless more recent handsets hadn't even received the February patch by then.
The Galaxy S5 Neo (SM-G903) has now been spotted on GFXBench. The benchmark listing for the device tested reveals that it was running Android 7.0 Nougat. This strongly indicates that Samsung may be testing the Nougat update for this device. However, it's unclear if and when the company is planning to release it.
It may be over two years old but the Galaxy S5 Neo is more than capable of running Android 7.0 Nougat. It has the same hardware specifications as the Galaxy A5 (2016) which is definitely getting Nougat. So it just may be a matter of time before Galaxy S5 Neo can get a taste of Nougat as well.
