If you are not happy with your notification light, then you can change and tweak it. Go to the Android Market and download an App called Lightflow.

You might need to enable the notification light before the App works. Go to Settings – Display. Then check Pulse notification.

Face Unlock allows you to unlock your phone by holding it up to your face. It is highly recommended to use the Improve Face Unlock feature to make the recognition faster and more accurate.

First, ensure you have Face Unlock enabled. Menu – Settings – Lock screen. Then chose Screen lock Face Unlock.

Once that is done go to Menu – Settings – Lock screen – Improve facial recognition. You might have to do this a few times to improve the speed of recognition. It is also a good idea to position the phone at different angles to your head to improve the accuracy.

WARNING: Some of the following MAY delete your music library. USE AT YOUR OWN RISK.

There are a number of solutions to this error. Go through the following steps:

Go to Settings – Applications. Then swipe right to left to go to All (along the top). Then find the App called Media Storage. Click on that and select Force Close. Then select Clear Data. (WARNING: this may delete your music).

Next, go back to list of Apps and find Music Player. Again, press Force Close and then Clear Data.

Once that’s done, go to the Play Store and download an App called Re Scan Media and run it. Wait 5 minutes for the device to re-scan your media.

If you still cannot play your music, then try turning your phone off and removing your SDCard / memory card (if you have one). Then turn the phone on without the card. Then turn it off again and reinsert the card. Finally turn it on again with the card back in.

If you still can’t play music, then some users have said that there may be a conflict with the Twitter App. Try uninstalling this and see if the error persists.

Depending on how your phone is set up, sometimes you will see lag when swiping between homescreens. There are a number of things you can try to fix this, as follows:

First, try restarting your phone. This will fix many problems.

If that doesn’t work, then remove any Widgets that pull data to the phone, such as Twitter, Weather widgets etc

If you have Live wallpapers turned on, then try turning them off by going to Settings – Wallpapers, then changing to a different Wallpaper.

Go to Settings – Developer Options – Window Animation Scale and Transition Animation Scale. Try changing these to 0.5x (or even 0).

Sometimes the problem can be with the phone or operators skin or launcher, so try going to the Play Store and downloading a third party launcher such as Nova launcher or Go LauncherEx. Note: you will need to re-create your homescreen shortcuts, but they are both great launchers.

Another tip is to always press the Back key instead of the Home key when leaving Apps. The Back key will often close the App properly, while the Home key will leave it running in the background.

The stock Android browser does not have a privacy or incognito mode, so the best solution is to download Google’s Chrome browser for Android from the Play store. Then open Chrome and go to Settings – New incognito tab.

Another option is to use the popular Dolphin browser whenever you want to browse privately. Then each time you exit, Dolphin asks you whether you want to delete your Cache or History. If you select yes, then your activity will be untraceable.

If you want to check how much RAM you have available, go to Settings – Application Manager. Then swipe from right to left so you see the Running Apps. At the bottom it should say how much is used and how much is free.

Jelly Bean has improved the facial unlock feature by creating a setting whereby you must blink when unlocking your phone. This prevents fraudsters using a photo of yourself and holding it up to the phone.

To activate this feature go to Settings – Lock screen – Screen lock – Face unlock. Then setup your facial unlocking.

Then once that is done, go to Face unlock again and tick Presence check.

If you like your Apps neatly sorted into folders, then there is a simple way to accomplish this.

First find the first App you would like in a folder. Then choose a second App. Press and hold on the second App and drag it over the top of the first App. They will both combine into a folder.

You can repeat this process to add more.

There are a couple of ways to bring up one of your contacts.

First, while in your Contacts App, simply start typing in the search bar at the top of the screen.

Or else a quicker method is to use the Goole Search widget (installed by long pressing on a vacant part of your homescreen and installing the widget) and start typing the name of the contact you want to dial. This will quickly filter the correct contact.
