Cellphone under warranty being damaged through one's own doing

Q: About 2 years ago a purchased a cellphone from a store that offers an extra warranty which I had taken out that says they will provide you with a new phone if something happens. The warranty covers accidental water damage and screen cracks etc. There is some terms and conditions that basically say that if it was intentional/deliberate then that would not be covered. One day whilst using the phone I thought some dirt/napaak might have gotten onto the phone, so i took some water in my hands and put it over the phone. Regrettably the phone had gotten water damaged and I had taken it in to the store to get it fixed/exchanged. When I took it in to the store, they did not ask how or when it happen but rather took my personal details and a week later gave me a replacement phone. Of course, my main intention was to just clean the phone, but unfortunately it had gotten damaged.

1. Is the replacement phone they gave me ok for me to use? I ask since the phone had broken through my own wrong doing even though not deliberate and they did not ask anything about it

2. Did any of the work i did for work purposes on the phone become wrong for me to do?

3. Coincidentally after a couple of months the replacement phone they had given me fell in the rain and yet again I went to them. This time they asked how it happened etc and I explained to them it fell in the rain and they gave me another replacement phone again. Is this phone also OK for me to use since the first one (not original, first replacement) had to be given in?

4. Can I sell this second replacement phone and use the money from it?

Giving the wife mahr

Q: When my father proposed to my mother, he dedicated Surah Al-Imran, which he memorized off heart, as her “Mahr” (dowry). And when my husband proposed to me, my father told him that he would have to memorize a Surah of the Quran as my mahr. The wedding will not go on unless I’ve received my mahr I was asked to pick one of the surahs. I chose Surah Al-Noor. For all the laws that Surah contained within it and for the fact that it seemed hard to memorize on my behalf. And before our wedding day; aside of being busy preparing for our “Newly wedded Nest”, the Quran wouldn’t leave my husband’s hand an entire month as he was memorizing the Surah. A few day before our wedding day, my husband came to recite to my father the Surah which he had completed. My father told him every time you make a mistake, you would have to start from the beginning all over again. My husband began reciting Surah Al-Noor with his calm/gentle voice in such a “beautiful” scene which I will never forget. My mother and I would look at one another and would smile awaiting my husband to make a mistake so he would have to start all over again and by that increase my “Reward”. But my husband – May Allah bless him – had memorized the Surah off heart and didn’t even forget one single verse of it. Once he finished my father hugged him and said to him: “Today I shall marry my daughter to you, for you have fulfilled her mahr and your pledge to me..” He didn’t pay me a financial mahr, and we didn’t buy gold worth tens of thousands. He sufficed me with Allah’s words as an oath/contract between us.

Regarding the story above, is this type of mahr accepted in Islam?

Marital problems

Q: Recently my family did my marriage and my husband is too much taller and fat compare to me. When I'm having sex with him I'm suffering from too much pain. I can't explain you. So just I want to known is it compulsory to have sex with him every day or for few month I can have sex with him once in a week. Even before marriage no one ask me about this boy just they did my marriage with this man. So please can you tell me is it compulsory to have sex with him every day or I can have sex with him once in a week?
