21.24 Does my phone support the three-button line control
headset?
Yes. Your phone can use most of three-button line control headsets on the market.
However, your phone does not support the line control function of certain headsets, for
example, Apple headset.
To have better audio and line control operation experience, you are suggested to use Huawei
original headset.
21.25 How do I obtain bootloader unlock permissions?
Visit Request unlock code to request an official unlock code. Follow the onscreen instructions
to unlock your bootloader.
Read the unlock disclaimer displayed on the website carefully.
21.26 What do the different indicator colors mean?
The phone's status indicator can show battery status or event notifications.
1. Blinking red: low battery level; battery over-discharged and can't re-charge; your phone
can't power on.
2. Steady red (while charging): battery level is below the warning level.
3. Steady orange (while charging): battery level is above the warning level.
4. Steady green (while charging): charging is complete or nearly complete.
5. Blinking green: new message; new email; missed call; calendar reminder; missed alarm.
For some third-party apps such as QQ, Weibo, and WeChat, the indicator may also flash green when there
are new notifications.
21.27 How do I improve the game fluency?
1. Go to Settings > Power saving > Normal.
2. Go to Phone Manager > Phone accelerator. Close the apps that are temporarily not
used.
3. Go to Phone Manager > Storage cleaner. Clean the junk data in your phone according
to the onscreen instructions.
4. Go to Settings > Startup manager. Disable the apps that do not need to be initiated
upon startup.
5. Restart your phone.
Because the game screens and your phone screen may not be consistent, related compatibility
processing is required. A large number of special effects are added to the game apps or special
sensors need to be called, which also affect the game fluency.
