If you are browsing YouTube videos on your phone and they appear blurry, then this is usually because of your connection speed.

If you are using 3G / 4G and you’re in an area of low signal strength, then YouTube will sometimes automatically reduce the quality of the video. Unfortunately this can make the video very pixelated and of poor quality.

If you are using the standard Android browser, then when the video is in full screen, press the back button. Then press HQ and start playing it again.

If you are using another browser, then press the Settings icon on the bottom right of the YouTube video. Then change the quality.

This may improve the quality, but it may also lead to buffering issues.

Another solution is to use a WiFi connection, if one is available.

If you call someone regularly this can be useful as you will have a shortcut to them usefully placed on your home screen.

To bookmark a Contact on your Home Screen, then first go into your Contacts App.

Find the Contact you want to add to the Home Screen and go into their Contact details.

Then press More or the Menu key and select Add shortcut to home.

Then go to your Home Screen, find the Contact you’ve just added. Press, hold and drag to another position.

If this doesn’t work, then try this alternative method:
Go to one of your home screens.

Find a blank space, long press and hold.

Select Widgets, then scroll until you see the Contacts Widget. From here there are various options to add contacts to your home screen as bookmarks.

Android now has privacy or incognito mode built into the stock browser.

Open your Browser App and press the Tabs icon at the bottom. Then press the Menu or More button at the top. Then select New secret tab or New incognito tab or Secret mode security.

Another option is to use the popular Dolphin browser whenever you want to browse privately. Then each time you exit, Dolphin asks you whether you want to delete your Cache or History. You may need to enable this if it isn’t set up by default.

If you select yes, then your activity will be untraceable. You may need to check this is enabled in the Dolphin settings.

First open your Contacts App and select a contact. Then press Edit at the top of the screen.

Then should then see a photo icon. Press that and you will then see some options to either take a photo or select a photo from your Gallery.

Select the icon depending on your requirements.

To delete or remove home screen widgets, simply press and hold. Then drag the widget to the top-right corner of the screen and into the Trash icon.

Looking to find the IMEI nunber for your Asus Zenfone 4 Pro? 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 Asus Zenfone 4 Pro, 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 Asus Zenfone 4 Pro is locked or has no power for some reason.

To change the backlight screen timeout, drag down your notifications screen and press Settings.

Then select Display.

Then under Screen timeout you can set the screen time out duration.

You can also tell the phone screen to always stay lit when it is plugged in via USB:

Go to Settings – System – Developer Options. Then check Stay Awake.

Note: Developer Options is not always enabled by default. To enable, go to:

Settings – System – About Device – Software info . Then tap on Build number 7 times to enable this secret option.

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 bottom 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.

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 Brower, 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.

If you want to setup new email accounts, like Yahoo or Hotmail, go to the Play Store and download your favourite email service.

Almost all of them have an App now, so the setup is much easier than in the past.

Install the App and follow the instructions to set it up correctly.

Then if you want to modify or view your accounts, go to Settings – Cloud and accounts.

To access the scientific calculator, simply open the calculator App and rotate the phone to landscape mode.

The calculator will automatically change to a scientific one.
