Impurities on clothing and furniture

Q: My dress got soiled with stool and while I was washing it, my dress touched my body/thighs before squeezing the water from my dress. Then I continued washing my dress and squeezed it which means my dress is clean now. But this wet dress touched my body/thighs which became naapaak first and I did not wash it because I wanted to wash my dress first. So now did my dress become naapak again? If yes, so how many times should have I washed it - one time or three times? What if I have washed it only once and wore again and sat, slept, etc. Do I need to purify all the things?

Q: If phone is dropped in toilet and is covered with Najasah what's the way to purify it. The phone is expensive is removing the impurity by wet wipes or removing until Najasah can't be seen. Also so if najasah is on ones hand less then size of a dirham I.e the fluid from the private part not semen but the clear one. If the the person touches his phone does that become impure. Last question related to this if Najasah say again on phone but one can't see it, smell it or feel it, so like the one mentioned on previous question, if one was to touch that phone and then other thing would other things become impure. Also how does Najasah transfer, from one place to another.
