Samsung-Galaxy-S3-Tutorials

We want to make it as easy for you as possible to fix your problems with your Samsung Galaxy S3. So, together with our troubleshooter series, we publish posts that contain basic and advanced tutorials and guides. Many of these tutorials may not be new to you but there may be some you don’t know yet.

In this post I included two very important procedures–wiping the cache partition and performing factory reset. These two are the most common solutions to many problems especially those that are related to apps and firmware. If you have questions and problems, feel free to email us at [email protected] and we may include your concerns in our future posts. Now, find out if you already know the following tutorials:

How to Wipe Cache Partition

Android stores caches in a specific partition that can’t be easily accessed by the user. These caches are used every time a user opens apps. They are basic information that makes the process smoother and faster. However, there are times when these files get corrupted and affect the normal operation of the phone. If this happens, they have to be deleted so that the system will cache newer sets of data.

  1. Turn off the phone completely.
  2. Press and hold the Volume Up, Home, and Power
  3. When the phone vibrates, release the Power button but continue holding the other two until Android System Recovery screen appears.
  4. Use the Volume Down button to highlight ‘wipe cache partition’ and press the Power button to select it.
  5. Highlight ‘reboot system now’ and hit the Power key.

Factory Reset Via Settings

Factory Reset means that all factory defaults will be applied back to the device deleting all user settings and preferences. The easiest way to do is through the Settings menu while others prefer to use the code *2767*3855# as it does the same thing. One important thing you should know is that all data that are saved in your phone’s internal storage will be deleted and cannot be retrieved. So, before following the steps below, make sure you backed up your important data.

  1. From the Home screen, tap the Apps
  2. Scroll to the right and choose Settings.
  3. Scroll down and touch Back up and reset.
  4. Tap Factory data reset.
  5. Choose Reset device.
  6. Confirm your action by touching Delete all.
  7. All data and setting will be deleted and you will have to re-setup all your accounts after the reset.

Master Reset Via Recovery Mode

Master Reset, otherwise known as Hard Reset, will delete all your settings and data, then reformat the data partition. But just like Factory Reset, it will leave all firmware updates in the phone. If you purchased your S3 with ICS and it already runs Jelly Bean, the recent update will NOT be wiped. So, after the reset, the phone will still be running Jelly Bean. This procedure is a bit more complicated but here’s how you do it:

  1. Turn the phone off completely.
  2. Press and hold the Volume Up, Home, and Power
  3. When the phone vibrates, release the Power button but continue holding the other two until Android System Recovery screen appears.
  4. Use the Volume Down button to highlight ‘wipe cache partition’ and press the Power button to select it.
  5. When finished, use the Volume Down button to highlight ‘wipe data / factory reset’ and press the Power button to select it.
  6. Still use the Volume Down button to highlight ‘delete all user data’ and press the Power button to select the option.
  7. Once the master reset is finished, highlight ‘reboot system now’ and hit the Power button one more time.

How To Show Battery Percentage

Galaxy S3 is a powerful phone and with all its features enabled, its battery can only last for so long. One good way to monitor how much battery is left is to display the percentage on the notification bar.

  1. From the Home screen, tap the Apps
  2. Launch Settings and tap Display.
  3. Tick the checkbox next to Display battery percentage.
  4. Tap the Home button to return to the Home
  5. The battery percentage should be showing on the notification bar now.

How To Enable Email Sync

There are times when your email messages won’t come in and you think there’s a problem with your phone. More often, it’s just the sync that was disabled that’s causing this issue. Turn on the sync back and the problem would be gone.

  1. From the Home screen, tap the Apps
  2. Launch Settings.
  3. Under Accounts & sync, tap Email.
  4. Enable sync and check if your messages comes.
  5. After enabling the sync for a specific account and messages didn’t come in, go back to the Home screen.
  6. Pull down the notification panel and make sure “Sync” is enabled.
  7. Go back to Settings and choose Data usage.
  8. Tap the Menu key and check Auto sync data.

This will fix the email syncing issue.

  3. While inside the camera interface, tap the Settings icon (cogwheel).

Tether Internet Connection Via Bluetooth

This is for users who still don’t know they can share their internet connection via Bluetooth. Please note that some carriers or service providers don’t allow internet connection to be shared with other devices. So, proceed at your own risk.

  1. Turn on your Galaxy S3’s Bluetooth.
  2. Turn on the Bluetooth with your other device.
  3. Pair them and make sure it’s successful.

  5. Mark the checkbox beside Internet access.
  6. The other device can now use the internet from your S3.

Keep WiFi On / Off During Sleep

We’ve received a lot of emails asking why their WiFi connection disconnects with the phone sleeps or becomes idle. Many thought it’s a serious issue but it’s not. There’s a setting that will allow you to keep WiFi on or off when it goes idle.

  5. Now your WiFi will stay on or off even if the phone sleeps or goes idle.

Using Sound and Shot Mode

  2. Choose Camera.
  3. While inside the camera interface, tap the Settings icon (cogwheel).
  4. Scroll down and tap Shooting mode.
  5. Choose Sound & shot.
  6. Go back the main Camera screen and get ready to take your first picture with audio.

Disable Auto Word Replacement

Have you ever experienced having your words replaced by your phone while you type? The worse thing is, the words the phone used weren’t correct. I’m sure you’ll agree that it’s very annoying especially if you are going to send an important message immediately. Well, here’s how to disable this feature:

Clear Caches Of All Downloaded Apps

  2. Scroll to the right and choose Settings.
  3. Tap More and touch Storage.
  4. Find and tap Cached data.

Prevent Galaxy S3 From Scanning WiFi Networks

As part of making the phone “smarter,” it was set to always scan for available networks. Such feature is not only annoying at times but also drains the battery quicker. So, here’s how you prevent the phone from scanning WiFi networks and save battery:
