General best practices

• Avoid technical jargon.
• Try to concisely explain the situation, and explain what the user can do to resolve it.
• In most situations avoid "you", "you're", etc. Dissolve boundaries between user and device.
• Don't use an article before app names. For example, use "Take photos with Camera" instead of "Take photos with the Camera").
• Apps names are displayed in title case, but individual settings or modes are displayed in lower case.
• Use smart quotes, not plain quotes.

Forms
