Samsung's SM-G5510 model is certified by the FCC; entry-level model could be unveiled soon0
Meanwhile, the SM-G5510 did run through GFXBench, which revealed that the model will come with a 4.8-inch display, carrying a 720 x 1280 resolution. Under the hood is the Snapdragon 425 chipset offering a quad-core 1.4GHz CPU with an Adreno 308 GPU. 2GB of RAM is inside along with 16GB of native storage. A 12MP camera graces the back of the unit, while a 5MP front-facing camera shoots selfies and handles video chats. Android 6.0.1 is pre-installed.
Recently, the SM-G5510 received certification from the FCC, which usually means that a new model is close to being unveiled. What we do know about the device suggests that it will be a low-end model. We might have to wait for Sammy to unveil this model before we can determine if it is a Galaxy On handset, or if it belongs to another line altogether.
