  1. Hi. I looked at the info on the sim card for the Galaxy S7 and it doesn’t apply to mine. On mine I see a symbol that is a circle with a slash that runs diagonally inside. I was told it may be that where the sim card goes [inside the back] may be damaged. I can’t make calls or receive nor can I text or receive. The notice comes up as “mobile network not available” I can do everything else but that. Please tell me what I should do. The sim card was replaced and the battery is still good. Thank you.

  2. I’m having my sd cards end up going bad after a certain time (longer than 6 months), not certain on it’s lifespan. And then out of nowhere it stops working and gets corrupted. I can get SOME of the files off via my laptop. Right now, I’m unable to format the card, and end up having to purchase another one. It’s not very economical and I hate knowing that some of my stuff will eventually be lost because of the track record on using sd cards. I have a samsung galaxy s7 and have wondered if this is a widespread problem.

  3. Well, im not if this problem has anythin to do with my SD Card or anythin else but, the issue im gettin every few seconds is a message that pops up on my home screen: “Failed to load, please try again later” and its really annoyin.. i have no ideas what this is all about, im hopin that someone can help why i am getting this

  4. Im having a really annoying issue that i cant figure out. I have a Galaxy S7 and i have been using a 32gb SDHC card for a while without problems. I recently bought a 128gb SDXC to store all my music card and its been a disaster.
    -First i tried copying my music via Media Monkey. Transfer complete, in my computer card reads full 124gb. Place it in my phone and it recognizes 32gb/124gb. i put the card back in my computer and there is 32gb of data and the rest is corrupted.
    – so, i formatted it (exFAT) and manually transferred all the files…same issue when placing it in my phone
    – i repeated all of the above with a new, hiher quality card (SanDISK)…exact same issues
    – i then formatted the SD card as FAT32…same problem…my phone recognizes the card as 124gb but only gives me access to 32gb of it (which works perfectly BTW)
    I have no clue whats going on… please help!

  5. I never knew about the rebooting. Thank you so much it worked! I was so scared. In your opinion, is it easier to manage and store pictures on an iPhone if pictures are my main reason for having a smart phone?? Thanks.
