Hardware
Sound
Modem
The modem isn't working
In order to use the modem and WiFi/Bluetooth, you need to ensure the battery is inside the device and has a sufficient charge. Even when supplying the phone with enough power, the modem and WiFi chip will not work without a connected battery. Further, double check that you have no put the SD card into the sim card slot, or vice versa.
Battery
The battery is stuck inside the phone
The battery can be stuck in the phone if the screws of the frame are overtightened.
If your battery is stuck inside the PinePhone, grab a screw driver and completely unscrew all the screws of the midframe. Then pull out the battery (you may have to fully take off the midframe in some cases to get it out). And then rescrew the midframe, but only tighten the screws to the point where they are just barely tight to hold. This should allow you to remove the battery easily.

Software
Ubuntu Touch
How can I enable SSH?
Run "sudo start ssh" to get a one-time start or edit /etc/init/ssh.override and remove the manual line to make it auto-start.
Android
What's the status of Android for the PinePhone?
Currently, there isn't any major push to get Android running well on the PinePhone. The developer Icenowy did get a Android image to run and partly work, it was however slow and buggy, with major functions not working. A solution for running some of your android apps may be found in Anbox as of now. Anbox currently not included in Ubuntu Touch.
Why are my apps loading slower than on my Android phone?
Android has multiple techniques in place to speed up launching applications after the first launch, such as the "Dalvik cache".
