In the name of God, the Most Gracious, the Most Merciful, and peace and blessings be upon our Prophet Muhammad.. Brothers, the screen works for a quarter of an hour, then suddenly it turns off and the screen becomes white.. Its repair costs 100 to 150 riyals. And I don't know where the warranty is, honestly, otherwise I would have returned it because it hasn't completed two months.. I don't have time, to be honest, to take it and fix it.. Due to my work, I don't have time for repair.. But as soon as the screen becomes white, you must turn it off and turn it back on in less than ten seconds.. And it will work with you again, and after ten minutes or a quarter of an hour, and sometimes it takes up to an hour, and the screen will turn off again and become white.. Whoever is interested, my limit is 200 riyals. And God is the grantor of success.
