Check out power saving mode. This feature works in the background if enabled. Power saving mode under the drop-down notification bar works when your battery level is low by disabling power hungry features of the phone like screen brightness, CPU speed, background screen color in your internet browser, and heptic feedback.
Maximizing the notification bar. Your phone uses a lot of power when any of the connectivity options are used. Whether Wi-Fi or Mobile data/3G, your Galaxy S3 drains the battery level faster when any of these networking options are used. 3G for instance may cut your battery’s stamina from several days to just a day and a half, depending on your usage. Turning off Bluetooth, Wi-Fi, GPS, and 3G/Mobile Data can greatly increase your phone’s battery level.
Free yourself from unwanted calls using block mode. Avoiding people is sometimes needed even if we exude friendliness all the time. Block mode is a useful feature offered by Samsung, making it unnecessary to download another third party app for the same function. It allows you to control what things you need at certain times of day, especially not allowing calls during your sleeping hours. Blocking mode also allows you to create a white list or “approved” contacts that can contact you anytime. Blocking mode options can be accessed under Settings.
Adding more contact information from Twitter and Facebook. With its easy access to the Internet, the Samsung Galaxy S3 is a great platform for social networking, but it raises the notch higher in terms of providing you with more useful features by allowing you to pull contacts from both Twitter and Facebook. Simply install the apps and your phone will automatically pull contacts to your Contacts list without a hassle.
Using touchscreen gestures when in Contacts list. Texting and calling friends directly when in your contacts book has never been this easy. For instance, you can send a message a contact when in contacts book by doing a right-to-left screen swipe. This is obviously quicker than tapping on an entry and tapping on the listed phone number again. Really sweet.
Have fun sharing files using the S Beam. Sharing files has never been this easy and fun. S Beam is Samsung’s version of Near Field Communication (NFC) that allows quicker transfer of files between two compatible mobiles. This feature is limited to Galaxy S3 and Galaxy Note 2 though. It may not be as common as of yet but it opens an opportunity to show how NFC can be used conveniently between gadgets in the future. S Beam can be turned under More Settings submenu under Settings. Hardly an interesting feature if you know a friend with a compatible phone. And speaking of NFC, Samsung’s Galaxy S3 offers more than just another way to share files. This short-range connectivity type can also be used for mobile payments, making your phone as a tool for contactless payments. Support is not that vast at the moment but it offers a wide range of potential uses like making quicker payments for small items, subway, among others.
Offline reading option when visiting sites. The default Internet browser of Galaxy offers a unique feature not found in other browsers like Google Chrome by allowing users to save a web page for future reading when the device is out of range of Wi-Fi or 3G coverage. The saved pages are stored in the phone’s internal memory. To save a page, open the Internet browser and press the Menu soft key while on the page you want to save. Then, tap the “save for offline reading” option. If you want to see the desktop version of the site you are visiting, you can also tick the checkbox that says “Reading desktop site”.
Using Voice Search for faster search. Using Google’s own voice recognition technology, the Galaxy S3 lets users to surf the web quicker by speaking into the phone’s microphone. Samsung’s own S Voice can also be used alternatively for the same function.
Making your S3 a Note with capacitive stylus. There is no question that the Galaxy Note 2′s nifty S Pen is superb. Manufactured by Wacom, the S pen also enables full pressure sensitivity for writing, drawing, and taking notes. While there’s no easy way to bring this capability to Galaxy S3 due to design differences from Note 2, you can get a similar pen input device by getting a capacitive stylus. There are many available capacitive pens with tips that offer similar functions to the S Pen that should work just fine with Galaxy S3.
Don’t waste cash on the 64BG version. Getting a 64GB edition is not worth it. Aside from the fact that it is not widely available anywhere, the 16GB and 32GB editions are more practical choices. Unlike the iPhone, your Galaxy S3 lets you add more storage memory with its available microSD memory card slot. Expanding the memory this way is a lot cheaper than getting the 64GB version.
Upgrading to more powerful battery packs. With the popularity of Galaxy S3, it’s no wonder that there are many available batteries for this phone ranging from standard-size ones to overly bulky ones. Depending on the type and brand, some will double the battery stamina of your phone like Mophie juice pack designed specifically for the S3. The Mophie juice pack adds to the overall size of the phone as it takes it into its battery pack. Other options are also available online.
High Definition video output. The Galaxy S3 does not come with a cord for video output though it can stream videos to computers and smart TVs using Wi-Fi. But if you want to hard wire your phone to your computer or TV, you can use the Samsung MHL adapter. It plugs into the microUSB port at the bottom of the phone so a high definition signal can pass HD video and surround sound to other devices and TVs. The adapter’s other end will accommodate a standard HDMI cable.
Use AllShare for Wi-Fi streaming. Wondering how to allow your Galaxy S3 stream your photos and videos to your TV? AllShare is Samsung’s answer to that. Using DLNA (Dynamic Living Network Alliance) standard, a Galaxy S3 can wirelessly stream your videos and photos over a Wi-Fi network. AllShare uses DLNA protocol to let your phone pipe content to a TV or between other Samsung devices. There are many Samsung devices that now employ AllShare including TVs, Blu-ray players, and tablets.
Editing videos using the video player. Yes, you read it right! Samsung’s default video player lets you edit your videos within the app itself. Other than that, the video player also supports many file formats making it a handy tool for playing different video types. Samsung’s codec support for its high-end phones has always offered better video support compared to its rivals like Apple’s iPhones. It can even handle the popular MKV file format. Most of the time, you will not find the need to convert your videos to be able to play them on your phone. Simply amazing.
Video overlays. Another gimmick a Samsung Galaxy S3 offers is the feature that lets you multi-task by playing a video on top of the home screen. When playing a video, there will be a little button at the bottom right that you can tap to allow the video to float on the screen. The video will remain on the screen until you tap the cross icon on the upper left to close it. You can watch the video while you browse the web, read emails, etc. The video can be resized using the pinch gesture.
