(I’ll tell you right away: my English is not very good.)

If you go to Settings on the watch, then “about the watch” and press Version many times, then a text in Chinese opens with a choice: yes/no. Translated means: Enter test mode.

Has anyone tried this? What is it?

    Interlastic Damn, I really want to try this, but the risk… Will it be a brick or some Chinese test thing? And if I go in there, can I restore everything to how it was?

      NothingSpecial⚡ Yes you can, but pay attention to not press anything that has to do with data and software, as that might actually brick it. Use Google lens to translate live too. I have done it myself.

      EDIT: You’ve probably already gone into it now, but here are some useful things:

      Second to last option when entering test mode is to exit. The watch will reboot into the usual watch (no data loss).

      Second from the top option blasts you with full volume music, it’s just horrible.

      NothingSpecial⚡ it’s a test mode presumably for factory to test functions. The original watch pro had this too. You can use to test functions aside that it’s a novelty and has no value to average customer.

      Rob ⚡️ changed the title to Test Mode - CMF Watch Pro 2 .

      After entering the test mode my watch can’t receive call. I’m so frustrated.
