Fixing of Can't Use the Volume Key to Zoom In or Out in the Camera Apps

 
It seems that Android 4.3 Jelly Bean has been bringing some problems to the users since it launched at the first time. A few days ago, some insiders left their comments and asked why the zoom function of the Volume key didn't work in the Camera app after they had updated their Samsung Galaxy SIII to Android 4.3 Jelly Bean.

After some further investigations, I've found that there were two things that can caused the zoom function of the Volume key didn't work, the camera mode and the Home screen mode.


How to fix can't zoom in or out using the Volume key in the Camera app?
If you're also experiencing this problem, you can check the following steps to make the zoom function of the Volume key works again:

1. Check the camera mode
   Some camera modes (e.g: panorama mode) will automatically disable the zoom function. So, to make the zoom function works, you need to change the camera mode to another mode. You'll be informed with the error message "cannot zoom in or out in this mode" if you're using a camera mode where the zoom function is not allowed to use.
2. Check the home screen mode
   If your phone is using the easy mode as its home screen mode then it will automatically disable the zoom function. So, to make the zoom function works, you need to set the home screen mode to the standard mode. You can do so by using the following steps:
• Go to Settings.
• Tap My device tab.
• Tap Home screen mode and then select Standard.
3. Use the pinch to zoom feature
   If the step #1 and #2 didn't work, you still be able to zoom in or out by pinching the screen with two fingers.

For the record, I've tested these steps in the Samsung Galaxy SIV with Android 4.4 Kitkat and it worked. So, I can conclude that these steps should be worked in another Samsung Galaxy phones with Android 4.3 Jelly Bean or above.

  How to Solving of  Can't Find the Wi-Fi Direct Option on Samsung Galaxy S3

In Android 4.3, there are some options that changed its location in the Settings menu causing some users are having trouble to find them when they want to use them. As happen with one of the insider named Maureen who has the difficulty to change the Bluetooth name in her phone after she did update the phone to the Android 4.3. She said that she couldn't find the rename option in the Bluetooth menu, where the option is usually located. Apparently, in the recent update you have to change the device name to change the Bluetooth name.

Another problem with the similar causes also experienced by another insider named Richard who has send me an email and said that he could no longer find the Wi-Fi Direct option in the Settings menu when he want to activate this option to allow him transferring some stuff to another phone.

FYI, in Android Jelly Bean 4.2 and above, the Wi-Fi Direct has been moved to the Wi-Fi menu. Well, here are the steps to locate the Wi-Fi Direct option:

2. Tap My Connections tab.
3. If necessary, slide the switch next to Wi-Fi option to the right to enable this option and allows you accessing the menu.
