If you find that a particular App is sending you too many notifications, there is a quick way to disable these.

When you receive the notification, pull down the notification screen. Then long press on the notification, then Go to Settings/More Settings, from here you can turn notifications ON or OFF for that particular App.

The most recent version of Android now comes with a built in Flashlight / Torch App.

To find this, simply pull down to see your notifications. Then on the top bar (where you see your settings for WiFi, Bluetooth etc.), scroll across until you see Torch.

To silence the phone when ringing there are two methods:

Either press the Volume Down (or Up) button or if the phone is on a surface facing up, simply flip it over so it is facing down.

To show the Browser History, open your Android stock browser (the default browser). Then press the Menu or More button and select Settings. Then Advanced – Manage website data.

To clear history, go to Privacy and Delete personal data.

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 top 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.

Create Cloud Storage Backup – You can also select to create back-up in Google drive. For that Go to Settings – Backup & Reset and turn Back up data ?ON? and add your back-up account (Preferably the same account from which you signed in on Play Store). Then open Google Account icon and from there you can select folders for which you want to create back-up, you can also set frequency of creating back-up e.g. daily, monthly or weekly etc. Now you can delete data from folders for which you have opted to create back, but before that please make sure that back up has been created. You can access these files by signing in to Google drive using you Gmail email and Password.

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 Browser, 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.

There are a couple of ways to bring up one of your contacts.

First, while in your Contacts App, simply start typing in the search bar at the top of the screen.

Or else a quicker method is to use the Google Search widget (installed by long pressing on a vacant part of your homescreen and installing the widget) and start typing the name of the contact you want to dial. This will quickly filter the correct contact.

If you prefer a different voice when listening to the Google Maps voice navigation, you can select another language or accent.

To change this, go to Settings. Then select System – Language and input – Text-to-speech options. Then under the Preferred text-to-speech engine, press the gear icon.

From there, select Language and you will be able to choose from different languages or language variations.

To stop the Photo App or the Music player from indexing your files, place a blank text file called .nomedia in the folder containing your photos or music.

The best way to do this is to connect your device to a PC and then navigate to the relevant folder via your PC.

Looking to find the IMEI nunber for your Samsung Galaxy J7 Duo? Read on.

An IMEI is a unique serial number that is assigned to your phone. Each phone has a unique IMEI, regardless of brand and model. Most insurance companies would ask for your IMEI because this helps them report and block the device once it gets lost or stolen.

If you’ve just bought your Samsung Galaxy J7 Duo, it is best to keep its package box and avoid throwing that to the bin. That could be very handy when you do lose your phone and you need to trace it using the IMEI code.

There are several ways to get your IMEI number by just using your phone. The easiest way is to go to the dialer and press *#06#. The IMEI should be displayed on your screen after entering the code.

Now for those who dialled *#06# on their phones, some might be seeing two types of serial numbers. Just take note of the first one, because that is most likely the IMEI.

Aside from that, you can also go to Settings → System → About Device → Status, then scroll down to locate your IMEI number. This could vary a bit depending on your phone model. Some smartphones list the IMEI under the About Device section. So just scroll down in case you don’t see it under System or Status.

The IMEI is also often imprinted on your battery cover. This means that you have to dismantle the back cover of your phone to get a copy of it. This is rather inconvenient. If you can still access your IMEI using the phone itself, then just do so. Except if your Samsung Galaxy J7 Duo is locked or has no power for some reason.

If you regularly visit a website you can add a shortcut to your homescreen which can be quite useful, rather than entering the web address each time you want to visit the site.

You can either do this to an existing Bookmark, or simply a page you’re visiting:

1) Open your Browser App. Enter the website you want to bookmark. You may need to wait for the whole page to load first. Then press the phone’s Menu button or More at the top and select Add shortcut to home screen.

2) Open your Browser App. Find an existing Bookmark by pressing the Bookmarks icon at the bottom of the App. Select the Bookmark and repeat the above steps.
