Is it permissible to recite the Quran with a narration other than Warsh, and from which narration should one memorize it? Is it permissible to read half of a Surah from the Mushaf and then complete it from the phone? Is the reward the same for reading from the Mushaf and from the phone?

There is no harm for a Muslim in reciting the Quran with any of the authentic narrations from the ten reciters. However, it is preferable to recite the Quran with the narration well-known in one's country. Reciting the Quran requires oral transmission to correct pronunciation. There is no harm in reciting from a phone, and it is hoped that the reciter will receive the same reward as reciting from a [physical] Mushaf (definition), although reciting from a paper Mushaf is more preferable as it is prepared for that purpose.
