After the launch of the Samsung Galaxy S5, everyone is pretty much focused on the upcoming Samsung Galaxy Note 4.

The South Korean tech giant finally talked about the Samsung Galaxy Note 4 for the first time in public. At the Semiconductor and Display Technology Roadmap Seminar 2014, Samsung confirmed working on an AMOLED QHD phone. Immediately after announcing that, Samsung announced that it is working on a more impressive AMOLED Ultra HD, 3480 x 2160 pixel display with 820ppi on a 5 inches screen.

Apart from the jaw dropping screen of the Samsung Galaxy Note 4, another interesting aspect of the much anticipated smartphone is the chipset it will carry. The Samsung Galaxy S5 is expected to feature a 64-bit processor but it didn't happen. According to Samsung via CNET, Android is not yet ready for it but when the time comes that Android can accommodate the technology; Samsung has already the technology waiting. Rumours say Samsung Galaxy Note 4 might be the first device to score the technology because Samsung believes its 64-bit chips will be ready sometime this year.

"Our chip will be ready whenever the operating systems and ecosystem go 64-bit," Hong said. "We're pretty sure we're not going to be the bottleneck for that."

According to Samsung Numero Uno, J.K. Shin, speaking to Kbench, there would be definitely a new Note device coming this fall, "of course, in the fall, [there will be] a new model Galaxy Note. This will come out."

On the other hand, another feature to expect with the Samsung Galaxy Note 4 is the IP67 certification, similar to the Galaxy S5. According to ETNews, Samsung cancelled an order for LDS antenna in favour of newer H-IMA technology, which is easier to waterproof.

Although waterproof feature remains to be seen with the Samsung Galaxy Note 4, it will likely be water-resistant and dust-proof, which means that it is safe with a splash or two but it can't survive being underwater for more than 30 minutes.

"LDS antenna provide far better reception than the waterproof friendly IMA options, but the development of H-IMA means manufacturers can now ensure reception is still good while sealing up their smartphones," reports Tech Radar.
