Does a musical ringtone from a mobile phone, and turning it off during the Friday sermon, count as a distraction that invalidates the reward of the Friday prayer, making it merely like a Dhuhr prayer?

Musical phone ringtones are forbidden. Whoever forgets to turn off their phone during the Friday sermon must turn it off, even if the ringtone is permissible, to avoid disturbing the preacher and the worshippers. This action (turning off the phone) is not considered a forbidden frivolity during the sermon; rather, a slight movement for a valid purpose is not idle play. The meaning of "he has no Friday [reward]" for one who engages in frivolity during the sermon is that his prayer is counted as Dhuhr (noon prayer) and he is deprived of the reward and virtue of Friday. A Muslim must listen attentively and refrain from frivolity and speaking during the sermon.
