Display SizeWe ran a Galaxy Note 3 concept poll on our website and it was determined that the majority of the people who voted were looking for a Note 4 that kept the same the device size but had increased the display size by reducing the boarders.
Significant Battery IncreaseWe're looking for more than 100mAh increases. Sure the Note 3 will go for a day and a half on mild use. But sometimes, you just want to use that battery hogging app in full brightness and for hours at a time. And we all know how quickly the battery drains when we use our devices like that. So we would love to see battery life, at least double or even triple of what it is now. It can be an optional accessory that people can choose to carry, such as a battery door with a large battery and people can opt to use such an accessory on special days only when they think they need it.
AOSP-based Web browser (Note II Style Browser)Right now, the best browser available for the Note 3 is Dolphin browser. And although it gets the job done right, the browser on the Note 2 is still better in many ways, especially when you enable the Quick Controls and Full screen feature. The AOSP browser on the Note 2 runs on Android 4.4 and it works flawlessly. We would love to see this browser again on the Note 4.
RAW Capture from CameraRAW seems to be the hot topic of smartphones. Although there has been no official word about iPhone and RAW images, Android L will support RAW capture. And considering that the Note 4 will almost certainly come with the latest OS, RAW images from the Note 4 may be entirely possible. Adobe has been very busy updating their apps on both iOS and Android to support raw processing as well.
There are many advantages to shooting in RAW. Accurate re-white balancing during post processing, highlight and shadow recovery which would result in more visible dynamic range.
High Bit-rate 4K Video CaptureThe 4K video is superb, especially on the new Galaxy S5 that lets you shoot HDR video. The quality would be good enough for professional use if Samsung is willing to make some minor changes. Currently, it’s capturing 4K video at 50mbits/sec and that bitrate is too low to keep up when there is a lot of movement on the screen. So why not give the users an option to select something like 100mbits/sec for 4K video and let the user worry about the file size? High bit-rate video in the right hands is very valuable. Other features that are a must is the ability shoot 24p at 4K, also manual controls for shutter speed , ISO, and aperture are an absolute requirement as well.
Not surprisingly, there’s a known mod or hack for rooted users that lets you record 4k video at 100mbits/sec, and these changes may be entirely possible if Samsung is willing to give their users the right options in the camera app.
