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 see an insufficient storage available error, or find that you’re running low on your phone memory (not to be confused with your SD Card memory), then there are a number of ways to fix this.

This error can be very frustrating as it often means you cannot install new Apps, and some Apps may not even function properly because of this. We hope this guide is as comprehensive as possible, but if you find other methods, then please suggest them in the comments below.

The first step is to determine exactly what is eating up your phone’s storage memory. To do this pull down your notifications menu and select Settings and find Storage. It may take a while to calculate so be patient. From here you can see whether it is your Applications, Pictures, Audio or otherwise, that is causing the problem. Obviously, if it is photos or music, then the first step is to remove some of these (ensuring you do actually want them deleted of course!).

If it is your Apps taking up space, then you have a few options, as follows:

Uninstall Apps – Go to Settings – Applications – Application Manager and swipe to the ALL tab at the top. Then look at the bottom of the screen which shows how much free space you have. Often you will have very little Free memory, which is the cause of the error. From here, press your Menu button and select Sort by size. This will show you which Apps take up the most space and which will make the most impact by removing. Obviously don’t delete things like Gallery (which will remove your photos!), Internet (which is your browser), key Google Apps and so on. However if you have Apps you don’t use anymore, then uninstall them to free up space.

Clear App Cache (with an App) – For this method, you will need to download an App called Clear App Cache. However, this will only work if you can uninstalled enough Apps to free up enough space to install the App itself. Once installed however you can quickly clear the cache of all of your Apps, which should free up some space.

Clear App Cache (manually) – Apps such as Gallery, can sometimes generate a large cache (image thumbnails in this case) which can be cleared to free up memory. First, go to Settings – Applications – Application Manager. Then swipe from right to left until you’re on the ALL screen. Then press the Menu key and Sort by size. Then choose the largest App by pressing on it. Then select Clear Cache. Do this until you’ve cleared as much space as you can.

Dump your log files – This will only work on some devices, however it doesn’t cause any data loss. It simply cleans up your App log files. Go to your phone dialler App and press: *#9900# Then Select delete dumpstate/ logcat and hit OK.

Move Apps to SD Card (if you have one) – Settings – Applications – Application Manager. Flick from right to left until you get to SD Card. Then simply tick which Apps you’d like to move from Phone memory to SD Card memory.

Clear Browser Thumbnails – This one seems to be a bug in some versions of Android and/or some phones, but is a very quick and effective fix. Simply open your stock Android Brower, which is usually found by opening the Internet App. Then at the top right check if you have multiple tabs open. If you do, then swipe them off the screen one by one until you have none left. This can clear up hundreds of cached thumbnails which never clear unless this process is carried out. It has been known to clear several gigabytes of space for users that don’t close their tabs often.

Check folder/file sizes – The last method is great and involves installing an App called DiskUsage from the Play store. Once you install this it will show you which folders are the largest. You can then drill down to find out exactly what is consuming your precious space before deciding to remove the files or folders. You can also integrate the App with File Explorer Apps to easily manage your files. When it comes to removing files and folders it’s sometimes easier to do that by plugging your device into a PC and browsing the folders that way.

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.

If you would like to unmount your SD card for whatever reason, then drag down your notifications menu from the top of the screen and press the Settings icon.

Then find Storage – SD card – Unmount SD card.

Sometimes while typing long text or SMS messages you will get a message saying Converting to multimedia message. This won’t normally cause a problem, however some users do not want to send a MMS message.

There are a number of different settings to deal with this, however there isn’t really a way to prevent the phone from converting to an MMS. The reason for this is that any message over 480 characters cannot be sent as an SMS message. They must be sent as an MMS. The is a restriction of SMS messages in general, similar to the original limit of 160 characters.

What you can do however is ensure you get alerted when you have reached 480 characters. Then you can decide to send the message as an SMS and continue your conversation on a second message.

To check this setting is on, open your Message App and press More – Settings and More Settings – Multimedia messages. Then select Set restrictions and choose Warning. You will now be told when your message is being converted to MMS.

You can also change the settings for Creation mode which lets you restrict messages that go over a certain size. If you select Warning or Restricted, you should get further warnings when your message is really large and may not be handled by the network.

If you would prefer not to be told every time an Application has been updated, open the Play Store and press the Hamburger / Menu icons in the top left.

Then select Settings and untick the App updates available option.

There are a number of ways to speed up your phone. The following list are tried and trusted techniques:

Firstly, uninstall apps that you don’t use. Over time your device can get cluttered as some Apps are designed to always run in the background. If you don’t use an App very often, then uninstall it to free up memory and CPU resource.

Use Static wallpapers instead of Live ones. Live wallpapers often consume processing power and memory. Unless you really need them, uninstall them.

Use home screen widgets sparingly. These often slow down the phone and use up memory and CPU resources. If you don’t really need the widget, then uninstall it.

Install a great App called DU Speed Booster and DU Battery Booster. These Apps are prefect to run when your phone starts to slow down, you’re running out of memory or you want your battery to last for a few more minutes or hours.

Kill tasks occasionally – Some Apps will run in the background indefinitely unless you kill them. Most of them won’t cause a problem, but it pays to check your running tasks from time to time. Hold down your Home key and check the Task Manager.

Locking your phone is a great security feature, but when you’re at home it’s normally not necessary.

A featured called Trusted Places enables you to bypass the lock screen when you’re at specific geographic places.

To set it up go to Settings – Lock screen and security – Secure Lock settings – Smart lock – Trusted places.

You can also set up the bypass to work when your phone is connected to specific Bluetooth devices such as Smartwatches or Audio devices.

You can also override this (i.e. lock your screen when it is at the location). To override, just press and hold the padlock icon on the lockscreen.

This may not work on all phones, models or networks.

Sometimes you may need your screen to stay on when plugged in via USB.

To do this, Drag down your notifications screen and press Settings. Then under System, select Developer Options. Then check Stay Awake.

If you can’t see Developer options then you need to enable this.

Go to Settings – System – About device – Software info and press on Build number 7 times. Developer options will now appear in the System section of your settings.

When entering text into Apps such as your Messaging App, Facebook App and so on, you can tap on the words to start selecting text.

Normally, you would then drag the left and right sliders to select the word, or words you want to highlight.

If you double tap on a word however, it will quickly select that word.

Very handy for quickly copying and one words, name or place.
