HUAWEI ALE-L21/L02/L23 Smartphone FAQs (Applicable Outside China)

3.10 Can I scan a QR code using my phone?

Yes. You can scan a QR code on the viewfinder of your camera. Your phone can also identify
a QR code if it is on a photo that you are viewing in Gallery.

3.11 Does my phone support 3D acceleration?

Yes.

3.12 How do I know whether my phone has been rooted?

To check whether your phone has been rooted, it is recommended that you take your phone to
a Huawei's service center where professional tools are provided.
Connect your phone to a computer. On the computer, run adb shell. If $ is displayed, the
phone has not been rooted. If # is displayed, the phone has been rooted.
3.13 Can I remove the battery? Will configuring my phone
to automatically set the date and time generate data
traffic?
If your phone obtains the date and time from your operator's network when it powers on and
registers with the network, it does not use an Internet connection to synchronize date and time,
and no data traffic will be generated.
If your phone fails to obtain the date and time from your service provider's network when it
powers on and if you have enabled the automatic time update function, your phone
synchronizes the date and time with the network, which will generate minor data traffic.

3.14 Can I use my phone for recording?

Yes.
