The ruling on one who breaks his fast before sunset relying on a mobile phone program

Question:
Your Eminence. One of the brothers says: I was in Ramadan in a remote area with no mosques, and we broke our fast using one of the programs on the mobile phone. It advanced by mistake for ten minutes, so we broke our fast. Then it became clear to us that we had broken our fast before the time, so we abstained after we had eaten some fruit. Do we have to make up this fast for this day?

Answer:
Are you in the desert? The question says you are in the desert. My brother, in the desert you have the sun. You see the sun when it sets on the horizon and the night approaches from the east, then it is permissible to break the fast.
You do not look at the mobile phone, nor do you look at the sun and the approach of the night from the east, as the Prophet (peace and blessings be upon him) said: “When the day departs from here and the night approaches from here ” So you look at the setting of the sun. Do you not look at the mobile phone or anything else? The result is that you broke your fast before the time, so you must make up this day by fasting it, because it was not completed. Yes.
