A yellow triangle and an Android logo will appear. Press the Volume Down and Volume Up button together and a recovery menu should appear. Use the Volume buttons to move to the Wipe data/Factory reset option and then press Power to select. Again, use the Volume Down key to choose Yes and press the Power button again to select.

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.

 

Click to choose your battery
 

Here’s how to pair your device with another Bluetooth device.

First you will need to turn Bluetooth on. To do this, drag your finger from the top of the screen down, to show your notifications menu. Then press Bluetooth so the icon is green.

Then press the Scan button and your device will start to scan for pairable devices.

Choose the desired device and press Accept. You may be asked to enter a PIN or Password.

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.

When taking photos or videos, tap the screen where you want to focus on. The phone will automatically adjust the settings to improve the image or video

If you have been browsing websites that you would prefer other people to not know about, then it’s relatively simply to clear your browsing history.

Open the browser and press the Menu or More button at the top. Then Privacy – Delete personal data.

From here you can select whether to clear the cache, cookies, passwords and more.

To adjust your screen brightness, there are two options:

1) Simply drag your finger from the top of the phone down to pull down your quick settings screen. Then at the top there will be a brightness bar. Drag this left or right or press Auto.

2) Drag your notifications screen down and select Settings. Then under Device, select Display – Brightness. Then choose the desired brightness setting.

You can also select Automatic brightness to let the phone decide for you.

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
