P8 Smartphone FAQs
to listen to songs. If you want to make phone calls using the headset, you have to reinsert the
headset.
4.17 Why is the sound not stable when I play songs in
speaker mode at a small volume (two to three bars)?
Your phone is designed this way to bring you a better music experience. The sound details are
ensured even when you are playing songs at a small volume. However, your ear is so sensitive
to sounds that the changes of sounds at a small volume can also be sensed, which is a normal
phenomenon.
4.18 Why can I hear noise or current noise when I play
songs in speaker mode at the minimum volume?
1. The speaker is a large-power component, which is driven by a PA. When the volume is
reduced to the minimum, the PA is still working and outputting certain noise floor (similar to
a home theater at the minimum sound volume). When your ear is close to the speaker, you can
hear that noise, which is the noise floor of the speaker circuit. It is recommended that you do
not place your ear close to the speaker to protect your ear.
2. Your phone adopts the third-party sound effect commissioning algorithm in terms of the speaker sound effects. When the
volume is set to the minimum, the algorithm filter's deviation will be output through the speaker, that is, the current noise, which is
a normal phenomenon.
4.19 Why can't my phone play videos in MPEG-4 format?
The video file you are playing may be damaged or its coding is not commonly supported. You can
record a video clip and play it on your phone. The recorded video is in MPEG-4 format. If the
video is saved to the microSD card, you can copy the video to the internal storage and play it to check whether the
microSD card is damaged.
4.20 How do I modify the application that I use to share
photos?
Check whether any applications that can be used to view photos are installed on your phone, because they may keep the
sharing function of a certain application always on.
