Looking for a charger for your Samsung Galaxy J2 Core? Our guide shows you the best deals and provides advice on charger types.

Important: We take no responsibility for chargers purchased that are incompatible with your device. Please check your user manual or product descriptions before you buy.

The good news is that unless you own an iPhone (which uses the Apple Lightning Charger), almost all smartphones on the market today use the standard 5 watt Micro USB connection. This is great for consumers because it means you can normally borrow a charger from someone else if your phone is out of juice (unless they own an iPhone of course). Many shopping centres and events also provide charging stations for this connection.

Charger types
Chargers can be classified into the following four categories:

USB Charger– This is normally a simple cable that connects from your phone (micro USB port) to your laptops or desktop PCs (normal USB port). They’re super cheap and super convenient. They are often included in your phone box, but we recommend you buy extras so you can leave one at home, one at work, one at friends place etc.

Mains Charger– These also normally come in your phone’s box, but it’s also useful to have them dotted around the house or workplace so you’re never far away from a re-charge.

Car Charger– If you have a car, you should get a car charger. These simply plug into your cigarette lighter and the other end plugs into your phone. We recommend buying one for each car that you own.

Portable Charger – Also known as an external battery pack, these are great for camping, festivals or going anywhere where you may not have a mains power supply. They come in many sizes ranging from tiny portable ones providing one charge, to large power packs allowing you to charge your device multiple times.

The phone has the ability to send quick response text messages if your phone is ringing but you can’t answer it.

To change these, go to your Dialler App and press the Menu or More button. Then select Settings – Call rejection.

From here you can add or edit your reject messages.

Looking to find the IMEI nunber for your Samsung Galaxy J2 Core? 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 J2 Core, 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 J2 Core is locked or has no power for some reason.

To speed up your phone, you can turn off screen animations. Go to Settings – Developer options.

Then scroll down to Window animation scale and select that. From here you can choose to turn Animations Off. This will make screen transitions faster.

Note: Developer Options is not enabled by default. To enable, go to Settings – About Device. Then tap on Build number 7 times.

To change keyboards (if you have additional keyboards installed), you can switch between them by pressing the small keyboard symbol in the top left of your screen. You will need to be in keyboard input mode (i.e. typing something) for this to work.

Alternately you can add and remove key board from settings also.

For that go to Settings – Languages and Input and then tap on Virtual Keyboard.

Now you can add and remove keyboards from this menu.

Note: you need to have more than one keyboard installed for this to work.

Type a word that is not in the dictionary. The word will show up in the suggestion box to the left. Long press on the word and it will save to the dictionary.

A handy feature of Android is to quickly clear your notifications.

Simply pull down your notifications bar by swiping your finger from the top of your phone downwards.

Then when you see each individual notification, swipe your finger left or right to clear each one. You can do this with your Apps too – press and hold the multitasking button. Then swipe left or right to close Apps.

Depending on how your phone is set up, sometimes you will see lag when swiping between homescreens. There are a number of things you can try to fix this, as follows:

First, try restarting your phone. This will fix many problems.

If that doesn’t work, then remove any Widgets that pull data to the phone, such as Twitter, Weather widgets etc.

If you have Live wallpapers turned on, then try turning them off by going to Settings – Wallpaper, then changing to a different Wallpaper.

Go to Settings – System – Developer options – Window Animation Scale and Transition Animation Scale. Try changing these to 0.5x (or even 0).
(you will need to unlock Developer options if you can’t find this. Use the search form on this site).

Sometimes the problem can be with the phone or operators skin or launcher, so try going to the Play Store and downloading a third party launcher such as Nova launcher or Go LauncherEx. Note: you will need to re-create your homescreen shortcuts, but they are both great launchers.

Another tip is to always press the Back key instead of the Home key when leaving Apps. The Back key will often close the App properly, while the Home key can leave it running in the background.

To change your default font, go to Settings – Device – Display – Font. You can also change the font size here also.

Another option is to install the popular Go Launcher EX App. Then once this is installed, download their GoLauncher Fonts App.
