Asus Zenfone 4 Tips and Tricks

Looking for a charger for your Asus Zenfone 4? 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.

Then when you see your device, select Revoke Access.

Enter a name and click on Generate Password.

A 16-digit pass code should be generated.

Enter this new password in your Android device, along with the correct Google ID.

2) If that doesn’t work, then go to: https://accounts.google.com/signin/recovery

Choose one of the recovery options. Then enter the email you used when you set up your device.

Follow the options depending on your situation and you should be guided through an option to get back into your phone.

If none of the above works, then you may have to hard reset / factory reset your device.

Before you do this, it’s recommended that you plug it in to a computer and copy across any files (particularly your photos in the DCIM folder). However it may not be possible to do this on some devices as it will be locked.

Voicemail is one of this crucial phone features, which isn’t always obvious to find.

To set up your voicemail, then first open your Phone App. Then press the settings icon in the top right and select Settings.

Then scroll down to Voicemail settings. From here you will find various options including the number to dial to retrieve your mails. You might need to check with your carrier for the correct number.

Depending on your carrier you may have to enter the series of steps required to go through the voicemail menu, for example: *86,,yourpassword# (a comma inserts a pause).

When entering text into Apps such as your Messaging App, Facebook App and so on, you can tap on the words to start selecting text.

Very handy for quickly copying and one words, name or place.

To locate the screenshot you’ve just taken, go to your Apps and find My Files.

Then it should be under Device Storage or Internal Storage – DCIM – Screenshots.

It’s possible that they may also be found under Device Storage or Internal Storage – Pictures – Screenshots.

If you want to move the Screenshot to another folder, then long press on the file name. You should see a tick appear.

Depending on how your phone is set up, sometimes you will see lag when swiping between home screens or when generally using your phone. 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 long pressing on a blank area of the home screens and changing to a different Wallpaper.

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 home screen 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.

Lastly, there is a great app called DU Speed Booster which can help close Apps that are running in the background and optimise your phone’s memory.

Follow this guide if you want to check the data and WiFi usage on your Asus Zenfone 4.

In this day and age, staying connected is essential. However, whether we like it or not, most mobile data plans put a limit on our data usage each month.

Browsing through Social Media may be fine, but downloading and streaming content can easily eat up on your monthly data allocation.

Reaching your data cap means that you cannot stay online for the rest of the month. Worse, you may be allowed to go online but it also means a huge bill by month’s end.

1. Go to Settings → Connections → Data Usage
2. From there, you can set a limit or data cap for a certain time period or billing cycle (a week, month, etc).
3. You may also press the Menu option and tap “Restrict Background Data Usage.” This option will help you manage your data usage, especially for apps that run in the background (such as Instagram and Messenger). However, this also means that the apps may stop working properly.

To check WiFi usage on the Asus Zenfone 4, follow these steps:

1. Go to Settings → Connections → Data Usage
2. From there, tap on the Menu button (3 vertical dots on the upper-right corner of the screen).
3. Tap on “Show WiFi” then “Wi-Fi data usage.”

Alternatively, some Android handsets may need to follow these steps below:

1. Go to Settings → WiFi & Internet → Data Usage
2. Tap WiFi Data Usage to view WiFi stats.
3. From this menu, you can also view data/WiFi usage per app.

The methods above generally work for most Android phone devices. Some handsets may have slight variations, you should just look for something similar Connections, Networks, or Data Usage menus.

Huawei users however have to follow a different process. Below is a short guide to check data and WiFi usage for Huawei phone users:

1. Go to Optimizer → Data Usage
2. From there, you can view your data usage for the month.
3. You also have a Smart Data Saver feature. You may turn that on if you want to.
4. You can also tap on the apps which are shown to be big data consumers and adjust their usage/consumption accordingly.
5. You may also set a limit by tapping “More Data Settings” then “Monthly Data Limit.”
