Hey Bexley and welcome to dreamviews the best forum for LD!
I don't know if you have already looked into the Introductions but if not here are some helpful links about induction techniques, RC's and so on:

I think your reality check isn't quite good because I don't think you're gonna dream much about your phone or rather always have your phone with you. It#S better to question yourself what time and day it is and then go check it somewher but I prefer the phrase 'Am I dreaming?' to question myself all the time and if something is really weird I do other RC's like hold my breath and if I can still breathing I know that I'm dreaming. Useful for the beginning but when I have my nightmares that method doesn't function anymore... That's why I like to focus my attention on my atmosphere and surroundings more because in dreams there are always a few things which are totally different from reality

And thanks to that it was easier for me to becoming lucid in my dreams more often.
I hope my answer was a little bit helpful for you and good luck and success on your LD journey!
Sweet dreams
