Btw, you do know that I posted this dialer code 5689#*980# hours before puch0021 did and I am sure he just looked at this thread and answered your question.
About your broken knock-on, what settings did you change? If you can't even remember that you shouldn't have accessed the menu in the first place.
Honestly I clicked on multiple ones but only saw a response from a few.
1. "charging Mode On/Off." It flicks from on to off,b but I think it always does that.
2. "Device Test" opened something.
3. "Prx Drx On Off" > "LTE + WCDMA." It turned something red and I clicked on the remaining two items, which displayed some data. Im there now and everything is clear.
4."LGODL On/Off" showed me a star. I dont see it anymore. I think it was that menu item that displayed the star.
5. "ATS Start Property." I turned it on and off. Its currently off.
Can you explain the significance of: GSM SMS Test/ GCF Memory Full SMMA Test. image of saluting woman.
