LG G3 (T-Mobile) Review & Specs

LG G3 is a top-notch Android phone released many years ago, equipped with an extremely fast Quad-Core CPU ticking at 2.5 gigahertz, an enormous 5.5-inches multi-touch screen, a 13 megapixels back side camera and a 2.1 mega-pixels front facing camera.

This device feels much lighter than what you would expect from a device this size. The LG G3 is available in a nice range of color variations, black, purple, pink, white and gold. This phone has a wonderful design, with a thickness of just 0.35 inches. This phone is a compact phone, taking into account that it has a 5.5″ screen and it is only 5.76 inches long and 2.94″ wide.

This cellphone has an absolutely amazing 5.5-inches display with a 2560 x 1440 (Quad HD / 2K) resolution, giving this device a unique image quality. Its display uses IPS LCD capacitive technology, with a very good 450 candela/m2 brightness and allows multi-touch gestures.

This cellphone comes with a Qualcomm Snapdragon 801 8974-AC chip, backed up by a high speed 2.5 gigahertz Quad-Core processing unit and a large 3 GB of RAM. Graphic calculations usually consume a lot of CPU time, so it counts with a 450 megahertz Adreno 330 graphics processing unit to take care of them, leaving the CPU free for other tasks. The LG G3 counts with a 32 GB excellent internal storage and an SD memory card expansion slot, which allows the user to store hundreds of apps without thinking about filling it.

This cellphone counts with wifi connectivity (which can be shared with other devices around, as a mobile hotspot), 4G (LTE) high performance connectivity and also HSPA+ connectivity, which is a lower speed 4G variation or the fastest 3G internet connection, supported by HSDPA, HSUPA, UMTS and EDGE technologies. This cellphone uses a Micro SIM card for GSM carriers.

This cellphone is equipped with two cameras, a 13 MP back-facing camera and a 2.1 mega-pixels front facing camera. Even though it’s 13 MP might sound incredible the back-facing camera sensor size is quite small which makes photos be less detailed and darker than they should. It is capable of filming videos in 3840×2160 (4K) at 30 frames per second. Additionally, the camera features a large number of interesting characteristics like auto-focus, flash, optical image stabilization, fast burst mode, face detection shooting, HDR mode, smile detection shooting and geo tagging.

This phone also features many interesting features like Bluetooth, FM Radio, GPS (Global Positioning System), Infrared Transmitter and Near Field Communication (NFC), and multiple sensors like Light Sensor, Proximity Sensor, Accelerometer and Compass.

This phone packs a great 3000 mAh Li-Ion removable battery, which isn’t very promising for a cellphone like this. LG informs a talk time of 19 hours and a stand by time of 548 hours for this cellphone.

The LG G3 is very appropiate for you it doesn’t matter whether you are looking for a phone to mostly use social networks and internet browsing, want this device for work, want this phone to take lots of photographs or want it to play games.
