iOS: iOS is developed by Apple and is used on all iPhone and iPad devices. iOS devices tend to be a little more expensive, but they are also a little more user-friendly and have better security features. Apple is a little bit stricter on what apps are allowed for iPhone and iPad and does not allow you to install apps from unverified third-party sources. Android: Most non-Apple smartphones run on the Android operating system. It’s a little more complex and not as easy to use. Smartphone developers can customize the Android operating system for their own phone models. This means that the layout can be a little different from one phone make and model to another. Android is a little less strict on what apps are allowed the platform, and you can install apps from unverified third-party sources. This also means that Android devices have more security flaws and require you to be more vigilant about what you download and install on your smartphone.

On some older smartphones, you need to remove the back and take out the battery to access the SIM card storage area. If you don’t have a SIM card tool, you can use a paperclip to open the SIM card compartment. Some newer phones have an eSIM instead of a physical SIM card.

Pattern: This option allows you to draw across a 3x3 grid of dots to unlock your phone. Make sure you select a pattern that you can remember. Fingerprint: Many newer phones come with a fingerprint scanner. On iPhones, touch the Home button below your screen to scan your fingerprint. On Android, the fingerprint scanner is on the back of the phone below the camera. Retinal Scan: Some newer phones can use the camera to scan the retinas of your eyes. To use this feature, hold your phone up in front of your face so the forward-facing camera can see your eyes. The screen will usually mark where your eyes need to be placed in the camera. Facial Recognition: This method stores a 3D or 2D scan of your face and allows you to unlock your phone by viewing your face. No security: This option allows you to bypass the lock-screen security and unlock your phone instantly. This is not recommended.

On some newer devices, the Home button is on the screen itself rather than a physical button.
