回答“Why won't my phone turn on?”I got the answer for this one. If your phone screen is black and unresponsive to the power button, there could be a problem with your battery. Before replacing your battery, try charging your phone using an outlet or USB adapter. Once connected to a charger, hold the power button for about ten seconds. If the phone still does not turn on, you should refer to the link on how to replace your battery.
回答“Why is my phone frozen?”I figured it out. Sometimes smartphones will appear to be on and working but will be unresponsive to your touch. If this is the case, your phone is most likely frozen. This is something that does not happen too often but may occur if you drop your phone or have too many applications running. Before jumping to the conclusion that your phone is broken there are a couple things you can try first. First, try rebooting your phone. Hold the power button for about ten seconds. If the phone is unresponsive to this and does not let you reboot, you should try removing the battery. This will shut your phone down and allow you to try turning your phone on. If the problem repeats, the phone is most likely broken and will require replacing.
回答“Why does my phone have no audio?”I solved the problem. If the audio and sound are not working with your phone, there are a few possibilities that may be causing this. The easiest solution to this would be turning the volume up using the volume buttons on the upper left side of the phone. If the phone was muted then that would explain why the audio and sound were not playing. If this does not work and the volume was already turned up, you should reboot your phone. If neither of these fix the audio problem with your phone, then the speaker is most likely broken and you should refer to the link on how to replace your speaker.
