General characteristics
Type
Deciding on the type of device (phone or smartphone?) is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to choose a telephone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly less than that of a regular phone.

Much has already been said about this, I will not repeat it. I’ll just say that this is so far the only combination on the market with an energy-efficient processor, 1GB of RAM and not an exorbitant price from a reputable manufacturer. Well, the design looks cool, especially the blue one =) ...a workhorse.

In my copy, after removing the battery, the time and date are reset (take out the battery, hold it for 30 seconds and insert it back). Either the battery is defective or the model does not have one. It’s not critical, of course - there is synchronization for this, and you still don’t have to pull the battery very often (although there is no “hot” replacement of SIM cards and SD cards). But I still wonder, is this a “personal” problem or the whole series? Someone take a look, please. =)

For this money, it’s probably a sin to complain) The phone has two obvious weaknesses: the camera and the battery.
Do you want to carry your smartphone in your jeans pocket? Choose a compact 4” model
Current smartphones, even inexpensive ones, try to impress consumers with huge screens. 5, 6, or more inches. What if you need a device that can easily fit into your jeans pocket? The GIGABYTE GSmart Roma R2 smartphone has a favorable screen diagonal to resolution ratio for its price: it’s clear, quite compact, and inexpensive. It has a 4” WVGA (480x800 pixels) capacitive IPS display with five-point Multitouch support and impressive brightness. Saturated and at the same time natural colors, as well as all kinds of sensors (position, proximity, illumination) are available.
The key to long battery life is an economical dual-core processor
GIGABYTE Roma R2 is based on a modern, cost-effective platform powered by a 1300 MHz dual-core MediaTek MT6572 processor and Mali-400 graphics accelerator. Accordingly, there are 3G, Wi-Fi “n” wireless interfaces with Direct connection function, Bluetooth. And thanks to the presence of GPS, you will get the shortest route to the most hidden places on our planet, and even without traffic jams on the road. The relatively modest amount of built-in memory (4 GB) can be easily expanded with a microSD card (we recommend ordering it immediately for the kit and getting a discount).
"Stock" fourth Android without dubious "add-ons"
The GIGABYTE GSmart R2 Roma smartphone runs Android 4.2.2 with an updated, very smooth interface, smart keyboard and useful services like Google Now. You will probably say a special “thank you” to the manufacturer for the complete set of programs. Here, in addition to the usual clients for all popular social networks, there is an advanced notepad, a file manager, and a multimedia player. It’s gratifying that the developers did not “improve” the interface with their own shells; the “naked” Android of the fourth version looks complete and as thoughtful as possible without it.
“Live up” communication with spectacular “Instagrams”
Two SIM cards expand the “borders” of communication
On the question of why you need two SIM cards in your phone. Firstly, this provides expanded network coverage: where one of the operators no longer “catch”, there may well be a signal from another. Another great use is dividing contacts into different groups: work and personal life, main and backup numbers. Or you can take advantage of different tariff plans or mobile operators. A simple example: make calls from one line, and access the Internet from the other. The bottom line is saving money.
