Samsung Galaxy Note 4 has been in news ever since the Galaxy S5 was unveiled. The much-hyped device is reportedly arriving in the second half of the year and is expected to have a massive feature upgrade over its predecessor, the Galaxy Note 3.

The South Korean electronics giant is tight-lipped on its upcoming flagship device, but several reports have claimed that it would be unveiled in September, the same month Galaxy Note 3 was released a year ago.

According to reports that have emerged over the last few months, Galaxy Note 4 may sport a 5.7-inch super Amoled display, which is the same as Galaxy Note 3. However, Note 4 may have a 2560x1440 resolution with 500+ ppi, as compared to its predecessor's 1080 x 1920 pixels with 386 ppi pixel density. Other than 3 GB RAM, which is expected to be seen in both the devices, Samsung fans can expect massive upgrade in the upcoming next-generation smartphone.
