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 store a phone number that you have received in an email, hold down on the number and you will be given the option to call, send an SMS or add the number to your contacts
If you find yourself woken up by notifications, text messages or incoming calls, then there is a handy feature called Blocking mode.
To enable this go to Settings – Device – Sounds and notifications – Do not disturb.
From here you can set a From and To time in which to block these notifications.
You can also allow notifications through from certain contacts that you don’t mind bothering you.
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 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.
If you have used up all of your Quick Launch spaces, then there is a trick.
Once it is full, press and drag an App from the homescreen and move it over the top of an App in the Quick Launch area. Then release your finger. This will create a folder containing the original App plus the new one. This is a great way to have access to regularly used Apps.
If you like your Apps neatly sorted into folders, then there is a simple way to accomplish this.
First find the first App you would like in a folder. Then choose a second App. Press and hold on the second App and drag it over the top of the first App. They will both combine into a folder.
You can repeat this process to add more.
To see which firmware version of Android you are using, use the pull-down menu by dragging your finger from the top of the phone. Select Settings and under System, choose About Device.
This should list your Android version, Build number and Model Number.
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.
To delete or remove homescreen widgets, simply press and hold. Then drag the widget to the top-right corner of the screen and into the Trash icon.
