Most Android devices come with an alternative way of entering text called Swype. Many prefer this method and believe it is quicker.
When any text entry box appears, press and hold the box. Then select Input method: SWYPE. Once enabled, you simply drag your finger around the keyboard moving over the letters in the correct order to spell a word.
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.
By default, your phone will recognise swear words, but insert x’s instead of the word. To change this, go to Settings – System – Language and input – Voice input.
Then you may need to select your voice input system. Then toggle the Block offensive words option.
There are a number of ways, as below. The first two of these may be disabled on some networks/carriers or Android versions however.
1) Go to Settings – Device – Applications – Application Manager. Then swipe from right to left until you are on the All screen (at the top). Then scroll down to Contacts Storage – Clear Data.
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.

Battery types
When choosing a battery there are three main types:
1) Replacement Batteries (Genuine / OEM) – OEM stands for Original Equipment Manufacturer and is the battery that the manufacturer has specifically produced for your device. This is normally the best option in terms of quality, time between charges and overall battery lifetime, but these batteries can be a little more expensive, so it depends on your priorities.
2) Replacement Batteries (Non-OEM / Generic) – Another cheaper option is generic or non-OEM batteries which are often mass produced in order to reduce their price. They can also provide longer battery life by having a higher mAh (see information below), so these can be a good alternative to OEM batteries if you want to save money. The quality can vary however, so we recommend that you read the reviews before buying. Another problem with generics is that they may make your device run hot and they can also void your warranty if your phone develops a fault. In general we would always recommend you buy a Genuine/OEM battery if you can afford to do so.
3) External Batteries– These are ideal if you’re going to be away from mains power for a period of time, such as camping, festivals and so on. The idea is that you charge the external battery pack (from the mains) and then charge the phone off that. Often external batteries will only last for one or two full charges, however very large packs (with a high mAh rating) are available if you’re going to be away for a longer time.
Understanding mAh
Before you buy, you should also check the mAh rating. This stands for milliamps delivered per hour rating and essentially tells you how long the battery will last before it needs recharging. A high end phone with a large screen may have a battery above 2500 mAh, whereas a mid-range model (with a smaller screen and less bulk), may only use a 1800 mAh battery. As mentioned above, sometimes generic batteries can have a higher rating than the genuine battery. For example, if your phone comes with a 2200 mAh battery, you can buy a 2400 mAh generic battery which should mean it will last longer between charges. As above, be careful with generics however.
There is a great app called Moves by a company called Protogeo that makes use of your devices accelerometer to record your movements, whether by walking, cycling or running.

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. You may need to check this is enabled in the Dolphin settings.
