One thing I did when I was an avel (and am trying to continue) is leave my cellphone at home or in my car. I found that I davened better. - even if the cellphone is totally turned off if it was in my pocket it was a distraction. I figured if I am going to daven for the amud for 11 months, let me at least try to daven like a mentsh.
This deserves its own thread.
When I go for Shachris, I bury my phone in the tallis bag. It has happened to me that I forgot it there, and had to go back to get it, but being distracted in shul is by far worse. I would have loved to have cell-phone lockers in 770 (and have spoken to the Gaboim a few times about it, including offering to sponsor), so as to have a convenient solution for Mincha and Maariv.
IMHO, cell phones and talking in shul are major factors in the OTD pandemic. Think about it, if you were to go in from on the SCOTUS and be the only one in the chamber with the justices, given the opportunity to plead your case, would you have a side conversation? Would you allow your phone to ring, or even vibrate? What if you were to get an audience with Bill Gates, one-on-one to ask for participation from his foundation in a project. Would you have a side conversation? Would you allow your phone to ring, or even vibrate? What if Baron Trump would go into his father, who would stop everything in order to be present with his son, and give him full undivided attention, would Baron dare to have a side conversation or have a phone ring while his father has his eyes, ears and thoughts 100% towards him?
When we go into shul, we are one-on-one with Hashem. The above examples don't even come close to what that
reality is!
ETA: I just added emphasis above to stress that we all know about דעת עליון and דעת תחתון. While in our physical eyes, material things might
seem more real and possibly durable than things we only see בעיני השכל, the reality is the exact opposite!
