Etiquettes and respect for the Quraan

Mistakenly dropping the Quraan

Q: I have disrespected Quran many times. Most of the time it is unintentionally. But it happens many times. Such as today, I was reading Quran keeping it over two pillows and while reciting, it suddenly dropped down and touched my feet. My eyes were closed because I was reciting from memory. Many times the Quran Sharif dropped from my hand. I unintentionally touched it without wudu and it was touched by my feet one more time in my life when I was young. What do I do since it burdens my mind?

Reading Quraan on a laptop or phone

Q:

1. Can we recite/touch Quranic verses on mobile or laptop screen without wuzu?

2. Similarly, during her period, can a girl touch Quranic verses and their translation e.g. if a girl is learning tarjuma and tafseer, then can she continue to learn this way on the phone without reciting the Quranic verses, just scrolling down and learnng visually?
