HyperOS 4 Lock Screen: Liquid Glass, Expanding Clock and New Widgets

HyperOS 4's lock screen is the most visible part of the update: a translucent, layered look, a clock that expands and changes scale, and a wider set of widgets. Like any heavy visual change it arrives with two practical questions - how to configure it so it stays readable in daylight, and whether the extra rendering costs battery. Both have concrete answers in the display and accessibility settings.

Steps

1. Step 1 Update and confirm what your model received

   Feature availability varies by device and region. Check the update screen and the release notes for your exact model before hunting for a setting that may not have shipped yet.

2. Step 2 Set the clock style you want

   The expanding clock is one of several styles. Choose it in the lock screen section of the personalisation settings, and decide whether you want the full effect or a simpler layout.

3. Step 3 Tune readability first

   Translucent elements reduce contrast. If text is hard to read over your wallpaper, enable higher contrast or reduce transparency before deciding the design is unusable.

4. Step 4 Configure the new widgets deliberately

   Add the ones you read daily, and set whether they refresh on the always-on display. This is the main battery variable in the new lock screen.

5. Step 5 Test the lock and check battery

   Confirm your unlock method and emergency access still work, then measure battery over two full cycles with the new lock screen enabled.

Common Issues and Fixes

• Symptom: The new lock screen options are missing. Likely reason: Your model or region has not received the build yet. What to check: The system update screen and the release notes for your device.
• Symptom: Text is hard to read. Likely reason: Translucency over a busy wallpaper. What to check: Reduce transparency, increase contrast, or use a simpler wallpaper.
• Symptom: Battery drains faster. Likely reason: Always-on widgets and continuous blur rendering. What to check: The always-on display setting, then reduce the number of widgets.
• Symptom: The clock style reverts after a theme change. Likely reason: The theme controls the lock screen layer. What to check: Reset to the default theme, then reapply the clock style.

Quick Tips

• Update before looking for new features.
• Tune readability before judging the design.
• Keep always-on widgets to a minimum.
• Re-test unlock after any theme change.
• Give the build two full cycles before judging battery life.

Related Questions

Does Liquid Glass affect performance on older phones?

Blur and transparency add rendering work, which is most noticeable on older hardware. Reducing transparency restores most of the difference.

Can I keep the old lock screen?

Lock screen styling is part of the system build. You can simplify it with accessibility settings, but you cannot revert the design.
