Samsung Galaxy J3 Tips and Tricks

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 and press on Build number 7 times. Developer options will now appear in the System section of your settings.

If you don’t want to have to unlock your screen every time you take your device out of standby then go to Settings – Personal – Lock screen and security.

Then select Screen lock type and select None.

To soft reset your phone press and hold the Power/Lock button for around 8 to 10 seconds. The phone will restart automatically.

If that doesn’t work, then remove the battery (if it has one). Wait 30 seconds and put the battery back in. Then press the Power/Lock button to turn the phone on.

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.

Looking for a charger for your Samsung Galaxy J3? 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.

Android has improved the facial unlock feature by creating a setting whereby you must blink when unlocking your phone. This prevents fraudsters using a photo of yourself and holding it up to the phone.

To activate this feature go to Settings – Personal – Lock screen and security – Screen lock type – Face unlock. Then setup your facial unlocking.

Then once that is done, go to Face unlock again and tick Presence check.

This may not be available on all devices.

If you want to install Apps outside of the Play Store (called sideloading), then go to Settings – Personal – Lock screen and security and select Unknown sources.

This setting will allow you to download Apps onto your device that would normally be blocked in the Play store.

Note: use at your own risk.
