If you want to remove the Google Search bar, simply tap and hold the bar and a remove button will appear at top of the screen, drag the bar to that remove button, and the bar will disappear.

If this is not working, go to Settings – Applications – Application manager. Then swipe from right to left so you are on the All screen. Scroll to Google search and press Disable.

To change your default font, go to Settings – Device – Display – Font. You can also change the font size here also.

Another option is to install the popular Go Launcher EX App. Then once this is installed, download their GoLauncher Fonts App.

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.

Once you have done this grouping, you can give specific name to that folder. For that just open the folder (containing different apps), and tap on Unnamed Folder tab and add your desired name.

Android has a feature allowing you to update Applications automatically. This is turned off by default, but you can turn it on.

Open the Play Store App and press the Menu icon in the top left of the App. Then select Settings and in Notification section you can turn Auto-update apps on.

From here you can chose to do this over WiFi only or using your Data connection.?

Drag down your notifications screen and press Settings. Then select System – Language and input. Then under Keyboards and input methods, press the little Gear icon.

2) Go to Contacts. Then hold and press on a contact. Then choose the All option at the top of the screen and select Delete. .

3) Go to Settings – Personal – Accounts and sync. Then press More at the top and choose Disable auto sync. Then go to Gmail (or an account that your phone syncs with) and delete all of your Contacts from there. Then re-sync your phone.

4) Download an App called ‘Delete All Contacts’ and use that as a last resort.

The methods above will delete contacts from the Phone only, not the SIM card.

When browsing on your phone you may notice images are quite blurry. This is because your telecom provider is compressing the images before they are downloaded on to your phone.

There is no way to prevent this, but if you have a WiFi connection nearby, then you can turn that on. This will mean that all browser downloads come through the WiFi connection, rather than the carrier, and your images will appear normally.?

This also depends on your service provider and data package.

If you would prefer to correct your own mistakes, then go to Settings – System – Language and input.

Then select the keyboard you are using and press the Settings icon again.

You should be able to find a predictive text option on this screen.

If you get tired of receiving sales calls or want to block a particular number, then you can set up auto call rejects on your device.

Often you will get calls from unknown numbers. Depending on how cautious or curious you are, then normally it’s good practice to ignore such calls. If you don’t want to answer, but you’d still like to know who the call is from, then you can simply Google the number and there are a number of websites which lists phone numbers with details about the company of the caller. From these sites you can easily see if the call you received is from a dodgy company or not.

Once you have established that you want to block or reject the call in future, then open your normal Dialler App. Then go to Logs and find the number you want to block. Long press on the number and select Add to reject list.

From now on you will see that you received a missed call, however the phone will not ring and you won’t be bothered by the caller.

To manage or manually enter numbers on your reject list, then again open your Dialler App. Press your Menu key and select Call settings. Then Call rejection. Then select Auto reject list to see your reject number list. You can also manually add numbers from here

Sometimes you may get a notification from a particular App and you would like to change the settings of that App.

To do this, pull down your notifications screen. Then long press on the Notification of the App you would like to see the settings for. Then select the gear icon. This will take you straight to the App settings. Now you can change app settings as per your desire.
