I'm on a project displays the minutes and the seconds in upper row and in bottom it says what I must do now, it was very sensitive to vibration so I changed the position of lcd (on the breadboard) and I used a kitchen decoration to see lcd while sitting, but now it's frequently starts scrolling weird things in the 2 photos, and then it becomes normal like the other 2 photos, why? There isn't vibration and there isn't a bug in code (I'm using this code for more than a week, and it started this today)

weird things in the 2 photos, and then it becomes normal like the other 2 photos,
Not seeing any photos....
breadboards can have unreliable connections depending on how much use/abuse it has been through.
when that happened to me, my sketch was too big for my UNO. it ran out of RAM for variables.
