In the Prophet’s mosque (Allah’s peace and blessings be upon him) Sayyidi wa sanadi Mufti Mohammed Taqi Usmani (Allah preserve & protect him) instructed a murid who was reciting the blessed Quran  from his mobile phone,
‘In a place where a mushaf (printed text of Quran) is available it is best to read from it.

Reading Quran from a mobile application is permissible. However, the blessings of reading from a mushaf are more. The Quranic picture in mobile are the reflection of the text (not the original text).

Moreover, in reading from the mushaf an individual is more cautious and observant of the proper etiquettes (adaab). He should try to do this even when he is  reading from mobile (when mushaf is not available).

Qari Rahim Baksh (Allah have mercy on him) was a great haafiz and teacher of Quranic recitations (qiraat). He tutored thousands of students. However,  in spite of memorizing the whole Quran he use to do his regular daily recitation by reading from a mushaf and placing his finger on each single word. This was to get the maximum blessings possible. ‘
