This document serves as a user manual for the TCL 20 SE (model T671H), providing comprehensive instructions on its operation, features, and maintenance. The phone is designed to offer a "DISPLAY GREATNESS" experience, emphasizing its visual capabilities and overall user interaction.
Device Overview and Basic Operation
The TCL 20 SE features a standard smartphone layout with several key components and controls. On the front, it includes a receiver and a front camera. The display is a touch screen, allowing for interactive control. Below the screen, there are three navigation buttons: a back button, a recent apps button, and a home button. On the right side of the device, you'll find volume keys and a power key. The left side houses the SIM card slot/microSD card slot and a dedicated Google Assistant button. At the bottom, there's a microphone and a USB Type-C port for charging and data transfer, along with a speaker. The top of the device includes a headset connector and another microphone. The rear of the phone features a camera and a back flash.
Getting Started
To begin using the TCL 20 SE, you'll need to set it up by inserting a SIM card and, optionally, a microSD card. The phone supports nano-SIM cards exclusively and features hot-swap capability, meaning you don't need to power off the device to insert or remove the SIM card. To insert the cards, use the provided SIM pin to open the SIM tray, place the SIM card(s) and/or microSD card into the slots, and then carefully close the tray.
Charging the battery is another essential first step. The phone's charging status is indicated by a percentage displayed on the screen, even when the phone is powered off. To optimize battery life and reduce energy consumption, it's recommended to disconnect the charger once the battery is fully charged, switch off Wi-Fi, GPS, Bluetooth, or background-running applications when not in use, and reduce the backlight time.
To power on the phone, press and hold the Power key until the device starts up. You'll then need to unlock it using your chosen method (Swipe, PIN, Password, Pattern, Fingerprint, or Face recognition). To power off, press and hold the Power key until options appear, then select "Power off." A forced reboot can be initiated by pressing and holding the Power key for at least 10 seconds.
Home Screen and Navigation
The home screen is the central hub for all applications, shortcuts, folders, and widgets. You can customize it by adding frequently used items for quick access. The home screen extends horizontally, allowing for multiple pages of content.
Navigation is primarily done through the touchscreen. Basic gestures include:
- Touch: To open an application or select an item.
- Touch and hold: To access available options for an item, such as moving or removing applications.
- Drag: To move an object to a different location on the screen.
- Slide/Swipe: To scroll through applications, images, web pages, or move between home screen pages.
- Flick: Similar to swiping but quicker for faster navigation.
- Pinch/Spread: To scale elements on the screen, such as zooming in or out.
- Rotate: Automatically changes the screen orientation from portrait to landscape when the phone is turned sideways.
The status bar at the top of the screen displays phone status indicators (right side) and notification information (left side). Dragging down the status bar reveals the notification panel, and dragging it down again opens the quick settings panel. Notifications can be accessed by touching them, and event-based notifications can be cleared by touching "CLEAR ALL." The quick settings panel can be customized by touching the Edit icon.
Lock/Unlock Screen and Personalization
To protect your phone and privacy, you can secure the screen with a pattern, PIN, password, fingerprint, or face unlock. To set up a screen unlock method, go to "Settings > Security & biometrics > Screen lock."
- Pattern Unlock: Draw a specific pattern to unlock the screen.
- Face Unlock: Requires setting a pattern/PIN/password first. Hold the phone 20-50 cm from your face, positioning it within the square shown on the screen. For best results, enroll your face indoors and away from direct sunlight. Enable Face unlock to automatically unlock when the screen turns on, or swipe up first.
- Fingerprint Unlock: Touch the fingerprint sensor with an enrolled finger to unlock.
The phone screen automatically locks and enters sleep mode after a period of inactivity to save power. This timeout period can be adjusted in "Settings > Display > Sleep." You can also manually lock the screen by pressing the Power key once.
Personalizing the home screen involves:
- Adding items: Touch and hold a folder, application, or widget and drag it to your preferred home screen.
- Repositioning items: Touch and hold an item, then drag it to the desired position. Items can be moved between home screen pages by dragging them to the left or right edge of the screen.
- Removing items: Touch and hold an item, then drag it to the "remove" icon at the top of the screen until it turns red.
- Creating folders: Stack one item on top of another to create a folder. To rename a folder, open it and touch its title bar.
- Wallpaper customization: Touch and hold an empty area on the home screen, then touch "Wallpapers."
- Widgets and recently used applications: Touch and hold an empty area on the home screen, then touch "Widgets" to display available widgets. To view recently used applications, touch the Recent apps key. You can open an application by touching its thumbnail, close it by sliding it up, or switch between applications by sliding right/left. "CLEAR ALL" at the bottom of the screen closes all running applications.
