I contacted Samsung through the support Facebook site. They asked me how I formatted my site, the steps I used to factory reset my phone etc. I told them I have done a factory website multiple times and this issue has occurred using multiple sd cards. They said to take it to a Samsung store and asked for my address. It turns out I am not close to a store near me, so they asked me to send in my phone to them and that They would get it back to me within 12-14 business days. I told them this is my only phone and cant be without a phone for a couple of weeks. They said this is the only option if I want my phone fixed. I guess I could spend $30 to activate my old note 4 and then send in my phone and pay another $30 to re-activate my s7 edge, but I am thinking do I want Samsung to look at the data on my phone.
I gave them the link to this forum and told them many other people are having this issue and see a lot of other people posting about this issue. They suggested I contact Sprint or Best Buy. I bought the phone from Best buy and was told to contact Samsung. They don't have any silver s7 edges in stock and do not know when they will get them. This afternoon, my sd card reappeared. It had not been recognized for 27 hours.
I am not sure what to do. The fact that I can get the sd card that is not being read in my s7 edge and put it in my note 4 and is automatically recognized, I think there is an issue with the phone.
