Most tech experts call it the best value for money mobile. In Bangladesh you can buy it for around 18,000 TK (8/16 GB). In fact sometime it may sound awkward as you can buy a Symphony or Walton mobile at similar price with much advanced specs(at least on paper). Lets have a close look at the paper and reality. If you try to have a closer look at the specs you will find that some of the very important specifications is untold. Like the display PPI (important determinants of display quality), the processor and the chipset (you know dual, quad, hexa, octacore but who made it. You know the name of Intel for computer, do you think a quad core Intel and a non brand quad core processor is equal), GPU (tells about the graphics performance, OK sometimes you will find that but never the Adreno GPU), battery (you know the mAh, but, what about talk-time or standby time. A big battery doesn't always mean that you will have a long talk or standby time. Rather, it depends on overall handling of the hardware and network resources, RAM (1/2 MB but haw much user available). In providing the detail info about a device Symphony is much backward than Walton. Walton is doing well but they will have to work more for a perfection in this issue.
Ops..! that's quite a long story, not bothering you anymore. I am just telling you about the Moto G. It comes with a 4.5 inch IPS display at 326 ppi and with gorilla glass 3 protection. You already know Motorola is a Google company and always gets the latest Android update prior to anyone. It is not a high end device at all. Rather, it is a mid range all rounder. It comes with a 5MP main camera which is frustrating for many. But, it is the best among the 5MP shooters. It doesn't have a expandable storage (recently Motorola has introduced the 4G version which has the expandable storage capability. But it is not available in Bangladesh yet.) That is why I would suggest to have the 16GB version if you really want to buy one. Another cool thing about Moto G is that it is water resistant. If you really want to have a smooth android experience try this.
