South Korean giant Samsung Electronics Co., Ltd. recently unveiled its new Galaxy Note 5 phablet, as a successor to last year's popular Galaxy Note 4. According to The Verge, the new Galaxy phablet is expected to be available on Aug. 21.

In terms of the specs, here's the difference between the new Galaxy Note 5 and its predecessors, the Galaxy Note 3 and Galaxy Note 4.

Earlier this year, it was revealed that Samsung's Galaxy Note 4 phablet had earned the number one spot in the United States, in terms of customer satisfaction, according to a survey conducted by the American Consumer Satisfaction Index (ACSI).

The Samsung Galaxy Note 4 was commended by smartphone users for its bright and crystal clear 5.7-inch display screen.

Like the Galaxy Note 4, the new Galaxy Note 5 phablet also sports the same 5.7-inch Super AMOLED display screen with a 1440 x 2560 pixel resolution. In addition, both phones also come with fingerprint sensors and S Pen Stylus.

The Galaxy Note 3, on the other hand, sports a 5.7-inch display screen as well, but with a lower 1080 x 1920 pixel resolution quality.

Note 5 comes with a 16-megapixel rear-facing camera, like its predecessor, but with an upgraded 5-megapixel camera on the front. The Note 4 only has a 3.7-megapixel front-facing camera.

As for the old Note 3 model, it has a 13-megapixel camera on the back and a 2-megapixel camera on the front.

Inside, Samsung decided to use an Exynos 7420 processor for its new Note 5 phablet, along with a 4GB RAM and a massive 128GB internal memory option. Its predecessor uses a Qualcomm Snapdragon 805 and an Exynos 5433, and has a 3GB RAM and 32GB memory.

The previous Note 3 phablet uses Qualcomm's older Snapdragon 800 processor and packs a 3GB RAM and up to 64GB memory.

As for the batteries, the Note 3 has a large 3,200 mAh and its successor comes with a slightly bigger 3,220 mAh battery. The new Note 5 phablet now has a smaller 3,000 mAh battery.
