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.
Smartphones that are always connected to the internet are great, but if you have a data plan that is capped each month, then you will want to keep an eye on how much data you are downloading. Fortunately there is a built in feature to monitor this.
Go to Settings – Connections – Data usage. From here you can set a limit and set the usage cycle (e.g. a from and to date).
If you press the Menu key or More at the top of the screen you will also see a number of features such as restrict background data usage (although this will prevent some Apps from working).
To change the backlight screen timeout, drag down your notifications screen and press Settings. Then under System 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. Then tap on Build number 7 times to enable this secret option.
The Do Not Disturb is a very useful feature if you are in a meeting or somewhere where you want to block incoming calls or messages.
To enabled Do Not Disturb, drag down your notifications and go into Settings – Sounds and notifications. Then under the Notifications section, press Do Not Disturb.
Once this is setup, you can allow exceptions for certain Apps. To set these up, press Allow Exceptions, then App notifications. You should now see a list of all of your Apps. Choose one and then select Set as priority.
Now, when notifications come in via this App and you have Do Not Disturb enabled, you should see the notifications.
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.
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.
Note: you need to have more than one keyboard installed for this to work.
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.
To add a widget, simply long press on a blank part of one of your homescreens. Then select Widget. Scroll through the list of available widgets and choose one. It will be placed on your homescreen and you can move it around as you desire.
If you find yourself being stalked or receiving unwanted calls nuisance calls from people or companies then you should use the Call rejection mode.
Open your Dialler App and press More. Then Settings and More settings. Then find Call rejection. From here you can manage your rejection list of numbers.
To see notifications on your Lock screen, the best option is to download an App called NoLed from the Play Store. This will show notifications such as text messages, emails and missed calls as bright icons on your homescreen.
You can choose between very small squares or small icons and these can assigned by coloured.
