Smartphone tips for iOS and Android

1. Silence annoying notifications

If you have lots of different apps installed on your smartphone, it might be beeping and buzzing more often than you’d like.

To stop your phone lighting up with notifications every hour of the day, take a trip to settings and decide which app alerts are genuinely important.

  • Turn off notifications on iOS – Go to Settings > Notifications to show the list of apps. Click on each app to turn off notifications and change the alert settings.
  • Turn off notifications on Android – Open the Settings app, go to Apps & notifications > Notifications to take control.

2. Use Do Not Disturb mode for some peace and quiet

With Do Not Disturb turned on, you can temporarily disable notifications at specific times. You can still allow calls from certain numbers even while it’s enabled, or have it turn on automatically when you’re driving.

  • Turn on Do Not Disturb on iOS – Go to Settings > Do Not Disturb and turn on or off and find other settings.
  • Turn on Do Not Disturb on Android –  Open Settings, then go to Apps & notifications > Notifications > Advanced. Tap on Do Not Disturb to get started.

3. Cut down on your screen time

With many of us still working from home, it can be hard to mentally switch off after a long day of work. If you’re worried about how much time you’re spending on your phone, you can track your app usage.

Parents might also want to use this feature, also known as ‘Digital Wellbeing’, to monitor how often their little one uses their own smartphone.

  • Track screen time on iOS – Go to Settings > Screen Time to see daily and weekly use tallies, time on apps and even set a screen time passcode for children’s devices.
  • Track screen time on Android – Open the Settings app and select Digital Wellbeing to set time limits or use tracking.

4. Adjust screen brightness to protect your eyes in low light

Most modern smartphones now have a feature that can reduce levels of blue light thought to interfere with sleep. If you’re using your smartphone in a dimly lit room, you might want to give it a try.

  • Adjust brightness on iOS – Go to Settings > Display & Brightness to adjust brightness, light and dark screen, background and night-time settings.
  • Adjust brightness on Android – Open the Settings app and tap Display for brightness levels, night settings and adaptive mode that automatically adjusts the screen to your surroundings. If you just want to adjust brightness, pull down the notification shade and slide the bar at the top.

5. Increase text size and strength

If you’re straining your eyes to read from your smartphone screen, you can increase text size in just a couple of taps.

  • Increase text size on iOS – Go to Settings > Display & Brightness and Text Size to adjust the size, turn on Bold Text settings and adjust the display to zoomed, to enlarge text and app display size.
  • Increase text size on Android – Open the Settings app, then select Display to adjust font size.

6. Delete apps and organise apps into folders

Setting aside some time to tidy up your smartphone can make it easier to find your most used apps.

We suggest you try a bit of digital housekeeping to remove unused apps (they take up space on your phone) and organise the apps that you’re keeping into labelled folders.

  • Delete apps on iOS – Hold down the app’s icon on your home screen and click Delete App to remove or Edit Home Screen to remove multiple apps, or hold and drag into a folder.
  • Delete apps on Android – Click and hold on an app’s icon and go to App Info > Uninstall.

7. Block unwanted contacts and nuisance calls

Suffering from a constant barrage of phishing texts or spam phone calls? Blocking these numbers is straightforward and it’ll stop you from being tricked into handing over personal information.

  • Block numbers on iOS – Click the Phone app, go to Recent and press the i icon on the right. Scroll down and click Block this Caller.
  • Block numbers on Android – Open the Phone app and select Recent. Hold on the number and from the pop-up menu, choose Block/ Report Spam.

8. Decide which apps can access your location

Location tracking is vital for GPS and mapping, but not every app needs to use it. In fact, if you download an app that requests unusual permissions considering its primary function, that’s a red flag. For example, a calculator app shouldn’t want access to your camera.

You can allow an app one-off access to your location later if it needs it. To manage location settings, follow these steps:

  • Location settings on iOS – Go to Settings > Privacy > Location Services to toggle GPS, Bluetooth, wi-fi hotspot and mobile tower tracking. For individual apps, select an app and set the permission.
  • Location settings on Android – Open the Settings app and select Location > App permission to review and adjust the permission status for each installed app.

9. Use two-factor authentication (2FA) to protect your online accounts

Two-factor authentication (2FA) is essentially an extra layer of security for your online accounts. It usually means that a unique code is sent to your phone, which you then enter after your password to confirm it’s you.

  • Use two-factor authentication on iOS – Go to Settings and select your name > Password & Security to turn 2FA on or off.
  • Use two-factor authentication on Android – Go to your Google Account settings at myaccount.google.com > Security. Select Google > 2-Step Verification, click On and follow the steps.

10. Make an emergency call

If you haven’t configured your emergency call settings, there’s no time like the present. Doing so means you can quickly contact the emergency services without having to flick through your contacts.

  • Emergency calls on iOS – Go to Settings > Emergency SOS to turn on or off Auto Call. In an emergency, press the sleep/wake button five times to call an emergency number automatically, or after countdown, depending on Auto Call setting.
  • Emergency calls on Android – Hold down the power button and from the menu, click Emergency > Emergency Information to add contacts and any relevant health information.
