First of all, unlock your Android phone. If you own an Android phone then this step is really basic for you and shouldn't cause any problems.
Go to the main menu and look for the alerts at the top bar which is visible on the screen. Now, you have to place your finger at the top of your phone’s screen in order to reach the top menu bar.
Once you have placed your finger at the top menu bar, drag it down by sliding your finger downwards. A window will be pulled down. You might have to do this a couple of times for the menu to stay down; with a little practice you will be able to do it with just one swipe of your finger.
Here you will find all the latest alerts that you have received regarding messages and other information. Tap and hold on an alert which you need to clear from the above menu at your screen.
You will have to slide the alert (which you want to clear) over and off the screen so as to get rid of it. However, on some phones by tapping and holding down on a particular alert opens a small menu off to the side that gives the option for deleting this alert.
You need to make sure that you only clear those alert from the over menu which you don’t want to see. Try not to delete the wrong one as it will be difficult to find it again.
If you have any issues or problems with these instructions then just try them again and try not to skip any step. For continued problems then go online and you will find many websites and forums that deal with Android phones. You will definitely find what you are looking for along with a lot of other tips and tricks that you might apply to get things done quicker. If you don't find what you are looking for you can also post a question of your own and get some help from an expert user.
