Samsung has two mid-range smartphones we've known about for a while now. Their model numbers are SM-G5510 and SM-G5520. Both handsets have been spotted on GFXBench, but now it looks like they're entering larger testing in India. The SM-G5510 could be the successor to the Galaxy Grand On. It'll have a 5" display and a Qualcomm Snapdragon 425 processor, with 2GB of RAM and 16GB of internal storage. As for SM-G5520, no information or specs about it have been leaked online.
