Mobile aficionados will have to make a pretty big decision as two flagship Android devices have been unleashed this week: Samsung Galaxy S7 and LG G5. Both are hailed as the new must-have smartphones of both manufacturers, but as a consumer, which of the two is the better choice?

As the premier devices for their respective companies, there are several features similar with the two mobile phones. Both are powered by the new Qualcomm Snapdragon 820, which is expected to provide fast and efficient performance.

They also share the same Adreno 530 GPU and 4GB of RAM. This means that the new Samsung and LG smartphones will likely boast similar power, although the hardware and software features will also play a part in the performance.

Offered in slightly different sizes, the Galaxy S7 and the G5 will probably attract different consumers with its ease of use and screen technology. The Samsung device has a 5.1-inch Super AMOLED screen while the LG phone is a bit bigger with its 5.3-inch IPS LCD display. People will have their differing preferences with size, although the phones' 2560 x 1440 resolution offers more pixels per inch in Samsung's smaller display.

Photography enthusiasts will also have to make a choice. LG is offering a greater megapixel count with its 16-megapixel rear camera compared to Samsung's 12-megapixel shooter. However, there are other features that come into play including the latter's f/1.7 lens that promises improved low-light performance.

Although the 3,000 mAh battery of the Galaxy S7 is impressive, the G5's 2,800 mAh battery has its perks too. It's arguably the biggest edge of LG in the battle of flagship phones as the G5's unique modular battery system allows users to add more features to the handset. The battery can be removed and a slew of other options can be added such as a bigger camera, battery or a digital-to-analog converter. These modules make the LG model flexible in a way its rival isn't, so those who want an expandable device will be quite happy with this.

On the other hand, Samsung made sure that its strength and durability is impressive. While the curved glass makes the device prone to fingerprints and scratches, it makes up for it with its strong waterproof body. The Galaxy S7 boasts an IP68 environmental rating. It can be submerged underwater for up to 1 meter for 30 minutes as well as being dustproof for outdoor trips and the like.

With a host of accessories on hand, both devices are good options, depending on the users' priorities. Which one are you picking up soon?
