To prevent it from constantly turning off, it's worth increasing the automatic shutdown timeout in Settings > Display > Timeout, for example, to 30 minutes if you're going to be typing for an extended period. For more tips, see how to extend battery life.
Even so, it's a good idea to have one handy charger or external batteryEspecially if your phone's battery life is already running low or the battery is worn out. If your phone is nearing the end of its life or frequently freezes due to insufficient RAM or memory, using it as a keyboard for extended periods can be cumbersome and isn't the best idea unless you have no other option.
Notifications and ease of use
When the mobile screen acts as a keyboard or touchpad, notifications may appear in the middle and disturbing while typing or moving the cursorIf you want a clean experience, you can temporarily silence them, activate a "Do Not Disturb" mode, or disable notifications from the most resource-intensive apps while using your phone as a peripheral device.

For writing very long documents on a regular basis, a good old-fashioned physical keyboardMobile is great as a temporary alternative, for presentations, for controlling a media center or for getting out of occasional jams, but it's not the perfect substitute if you work writing every day.
If you prefer entering complex passwords on new devices and aren't keen on using Wi-Fi or Bluetooth, you might consider other options: for example, connect a small USB keyboardUse a dedicated wireless keyboard or, in some cases, use secure remote desktop solutions that allow you to paste the password from the trusted PC.
What to do if you can't get it to work?

Also check that the app you're using is compatible with your operating system and specific version for Android, iOS, Windows, or macOS. If the app is outdated, it can cause minor glitches; updating it from the store usually solves many problems.
If the app freezes sometimes, you should force stop it from Settings > Apps, and then clear cache and, if necessary, dataThen, reopen it and repeat the pairing process. This often resolves persistent locks.
Final considerations
