Exodus 20:5 KJV
Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me;
The bowing and serving were with respect to God/lordship.
The following was how Daniel's friends interpreted this verse, Daniel 3:
14 and Nebuchadnezzar said to them, “Is it true, Shadrach, Meshach and Abednego, that you do not serve my gods or worship the image of gold I have set up? 15Now when you hear the sound of the horn, flute, zither, lyre, harp, pipe and all kinds of music, if you are ready to fall down and worship the image I made, very good. But if you do not worship it, you will be thrown immediately into a blazing furnace. Then what god will be able to rescue you from my hand?”
16 Shadrach, Meshach and Abednego replied to him, “King Nebuchadnezzar, we do not need to defend ourselves before you in this matter. 17If we are thrown into the blazing furnace, the God we serve is able to deliver us from it, and he will deliver us from Your Majesty’s hand. 18But even if he does not, we want you to know, Your Majesty, that we will not serve your gods or worship the image of gold you have set up.”
Shadrach, Meshach, and Abednego interpreted the verse literally.
If you considered the image on your phone to be a violation of the previous line, would it be possible to "bow to or serve" it in some way, or is it already happening?
If you treat that image as your God and bow down before it and obey it, then yes, you have violated Exodus 20:5.
