The camcorder mode allows you to capture still images while recording video at the same time in full resolution. Love it!
Video Player. All the videos show the thumbnails in animated preview. Nice! Plus, you can playback a video in a separate floating window. Effectively, you can watch the video while doing any other tasks on the phone - reading emails, surfing Internet, browsing apps.
Auto Photo Tag. You can tag contacts to faces found in photos, and the Gallery app will identify matching faces for you to tag them. Similar feature a Google Picasa, this enables you to connect to them faster via on-screen pop-ups.
Scan Nearby Devices. Now the stock multimedia apps like music, video, gallery will scan your network folders for compatible files and stream to your phone to playback.
Some things I don't like about the new Galaxy S3:
LED Indicator too bright. Most other phones have small unobtrusive LED. Samsung Galaxy S3 has one large round indicator that glows brightly in the dark. Fortunately, you can look for third party apps to manage the LED, which also lets you customise the notification colour based on apps. I personally use Light Flow.
Smaller Home Button. It's not as easy to press the home button as the S2. The touch keys are also narrower so you would need to stretch your fingers a little more to balance the S3.
Glossy Plastic Phone Surface. The Galaxy S3 glossy plastic surface feels fragile and prone to cosmetic damages compared to the hardy Galaxy S2.
Battery life. Despite a larger 2100mAh vs S2's 1650mAh, it doesn't last a lot longer.
Loudspeaker. It doesn't deliver great audio but it's just audible for general listening.
Other Features
The Galaxy S3 has a few other features which I don't see myself using, but might work for you:
Extended Motion Activation
Previously on the Galaxy S2, there is already a few basic motion gestures, like zoom in-out, flip-to-mute. The Galaxy S3 now has a few more:
- Direct Call - while viewing a call, message, or contact details, just place the phone to your ear and the S3 will call the person.
- Smart Alert - if you have missed notifications, the phone will alert you when you pick you the phone.
- Tap to Top - just double-tap the screen and the contact or email list will jump back to the top.
- Shake to Update - shake the phone to search for Bluetooth devices.
- Palm Swipe - capture screen
- Palm Mute/Pause - mute or pause sounds by covering the screen with your palm.
Smart Stay
The phone detects you are reading and will not turn off the screen.
S Voice
The iPhone equivalent of Siri. It actually works when I ask to check my upcoming appointments, weather, or create message or make a call. However, I'm one of the majority who finds talking to a phone silly.
S Beam
The ability to transfer content to another compatible phone without wires or pairing.
Overall Opinion
As an existing S2 user, transiting to S3 is an ease, and it's a no-brainer that a newer phone is always better than the old one. The camera speed is improved and allows me to capture the moment faster. The screen is larger and lets me view more content. The Samsung Galaxy S3 further improves the interface to make it more user friendly and smoother with engaging features that helps you reach out to your contacts faster, making you more "sociable".
