Then scroll down until you see WiFi MAC Address. The address should be a series of Hex numbers and letters.

Having notifications come through on the lock screen can be handy because you don’t have to unlock your phone to see what the notification is about.

The problem with this is that someone may see the content of a notification (a text message for example) which you would like to keep private.

To change this setting to only display that the notification has arrived (rather than the actual content), then go to Settings – Lock screen and security.

Then select Notifications

From here you can enable or disable which apps you can show notifications from or at the top, select to Show or Hide notifications.

If you see the following error:
com.system.patch error

Then pull down your notification menu and choose Settings.

Then, select Lock screen and security – Other security settings – Device Administrator.

On the next screen, uncheck com.system.patch

Now, go to your App Manager and you should be able to uninstall it.

First open your Contacts App and select a contact. Then press Edit at the top of the screen.

Then should then see a photo icon. Press that and you will then see some options to either take a photo or select a photo from your Gallery.

Select the icon depending on your requirements.

Sometimes you will want to prevent your device from displaying or indexing folders on your Phone storage or USB storage.

To do this, simply rename the folder and place a . (full top / period) before the file or folder name.

This can be done through the Files App or by plugging your device in to your computer and renaming it there.

While using the standard Android Video App, you can lock the your screen while watching videos by pressing the power button.

This will disable the touchscreen buttons while the video is playing, but it won’t turn the screen off like the lock key normally does.

Note, this will only work on video files that you are playing that are stored on your phone and using the native Video App. It won’t work for videos played within websites, such as YouTube videos or other Apps such as MX Player, which have their own lock screen settings.

Warning: This will remove ALL data on the phone (but not the MicroSD card).

To perform a hard reset, or factory reset, then there are a number of methods to try:

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.

3) While the phone is turned off, press and hold the Volume Down button. Then, while holding, press and release the Power button. A menu should appear. Use the Volume down key to go to Clear Storage. Use the Power button to select the option. Then when asked to confirm, press Volume Up for Yes.

4) While the phone is off, press and hold down Volume Up + Home + Power buttons at the same time. Then release the buttons when you see the Logo. Use the Volume Down button to go down and the Home or Power key to select. Choose the Wipe data/Factory reset option. Then Select Yes to delete all user data. Then choose to reboot the phone.

5) A final method is to enter the code into your Phone App: *2767*3855# This method will not give you an option to reverse the process, so be careful! This method will only work if you can boot into your phone.
