How to use the auto-capitalization feature in device settings
If the Auto-Capitalization feature is turned on in your device settings, fields that can contain sentences automatically capitalize the first letter of the sentence. You’ll notice this on Description fields, Resolution Notes, Note subject and body fields, Search bars, Task text responses, and Quote details.
The setting is found within the keyboard settings for your device, although navigating to that setting will differ depending on the operating system and device format you use. On Android devices, it may be different per keyboard.
