erratically over time. While your smartphone may work fine with these
applications on the current version of webOS, it is possible that the
application could cause issues with your smartphone in future versions of
webOS.
If you installed an application via a mechanism other than App Catalog,
you may find that you cannot download or install software updates, but
the smartphone continues to prompt you to update. If you have installed
such an application, you need to remove the app before attempting to
update your webOS smartphone. Follow the developer's instructions on
how to uninstall these apps.
If you installed an app that was intended for a wireless service provider
other than yours, that app is also not certified by HP for your smartphone
and you need to uninstall the app before updating your smartphone.
NOTE Be sure to make a backup copy of any information stored in the app
before you uninstall it. If the developer does not provide a way to back up the
data, you can write down the information to save it. Alternatively, hold down
Option + Sym + P to save screen captures of important data to the
screencaptures folder in Photos.
If you see issues with your smartphone after a webOS update and you
have a homebrew application installed, use webOS Doctor to restore your
smartphone to factory default settings. A partial or full erase does not
return the smartphone to factory settings after some homebrew apps have
been installed. See T6. Tether your smartphone to your computer and
reinstall webOS.

to my computer
You can copy music files on your smartphone to your computer for use
with a desktop music player. For instructions, see Copy files between your
smartphone and your computer.
NOTE The Amazon MP3 app is not supported by all wireless service providers.
If it's not in the Launcher, it is not available.
I copied files from my computer, but I can't see or play them
on my smartphone
When you connect your smartphone to your computer in USB Drive
mode, you can copy any file onto your smartphone. However, each
media application on your smartphone – Photos, Music and Videos – can
display or play files in certain file formats only. If your media file is in an
unsupported format, you can't use it on your smartphone.
For a list of supported photo types, see Photos. For a list of supported
music and ringtone file types, see Music. For a list of supported video file
types, see Videos.
When I open the folder representing my smartphone on my
computer, I see subfolders. Do I need to move my files into
these folders?
The default folders are there to help you organise files you copy to and
from your computer. But you can copy files from your computer into any
folder you want – you can create your own folders or just drag your files
