First it was dual cameras. Then it was bokehs, a.k.a. portrait mode. These days, it seems that the battle over smartphone cameras is moving over to higher level of optical zoom that won't force OEMs to bulk up their phones. Huawei has done it and so has OPPO so it's really no surprise that Samsung, and soon even Apple, are already following suit. The bigger question, however, is whether this 5x optical zoom camera module will debut on the Galaxy Note 10 and the chances of that seem to be a bit slim.
