Simple-Contacts VS Simple-Dialer

For Contacts -> https://github.com/SimpleMobileTools/Simple-Contacts

"Simple Contacts" https://github.com/SimpleMobileTools/Simple-Contacts or "ContactYou" https://github.com/Bnyro/ConnectYou

Don't use that app, and disable it if you can. Use https://play.google.com/store/apps/details?id=com.simplemobiletools.contacts / https://f-droid.org/packages/com.simplemobiletools.contacts.pro if you can, no funny business with this amazing open-source (https://github.com/SimpleMobileTools/Simple-Contacts) app

What happens if you try a third-party contact app like Simple Contacts?

Simple Contacts Pro (version 6.19.1): Contacts address book for managing recent contacts and vcf contact backups

Simple Contacts Pro (version 6.19.0): A premium app for contact management with no ads, supports groups and favorites

I bought Simple Contacts Pro, it's great but it has enough papercuts to where I went back to True Phone. Here are my bug reports:

Set default phone number for contact: https://github.com/SimpleMobileTools/Simple-Contacts/issues/...

Cannot create new group (category) for Nextcloud account/address book: https://github.com/SimpleMobileTools/Simple-Contacts/issues/...

Favorites tab showing contacts from all accounts: https://github.com/SimpleMobileTools/Simple-Contacts/issues/...

That's weird, does it work when using another contacts app such as Simple Contacts?

Simple dialer, imo best

If you only want to leave the screen on during phone calls, you can use Simple Dialer which has an option to leave the screen on: Disable proximity sensor during calls.

Simple Dialer (version 5.14.0): Manage phone calls with this simple phone dialer app with phonebook

Can you try a different dialer app like Simple Dialer or Koler? See if the issue still persists. Please be sure to turn off Bluetooth, WiFi, etc. just in case.

Is this distinct from Dialer?

Here is one of them link
