    I have a Nokia Lumia 635 AT&T locked version bought from Bestbuy on Thanksgiving. It works fine until one day as the callers said they doesn't hear my voice on their end. I checked with Bestbuy and they said I have to reach AT&T customer care for that. I did and end up with getting a factory refurbished (not new :( ) as a replacement. I had used a 8GB SD card on my old 635 and used the same in factory refurbished phone that I received. But recently I realized the SD card is not recognized by this phone. In Storage sense, it shows there is no SD card is attached. I tried with another 32 GB SD card that I have but still no luck. Can someone know how to fix this?

    BE SURE TO POST A DETAILED FOLLOW-UP ON WHAT TRANSPIRES!

    Have a tip that might help:
    I've been all over the net looking for info "STORAGE SENSE" not showing a installed SD card as I have a Nokia Lumia 635 (Boost/Virgin?Sprint) in which is brand new in which AFTER using it for basically a hr after firing it up for the first time installed a Samsung 64GB EVO Class 10 microSD Card with Adapter purchased directly from Wal-Mart.com as there were alot of FAKES being reported on Amazon /Ebay. Figured if there was a problem I could handle the exchange locally.
    (Lots of fakes being cards that are for example really only 8Gb and the card has been tampered with to make it look like it's 64GB and if you write files smaller than 8GB.. depending on how"good" the card is data might get written to the card but files larger than the "real" size of the card of course fail to write.)

    INFO on the Fakes, and info/ link to app named "h2testw" to test:
    (App says it can be on Hard drives, usb, dvd/cd, etc)
    https://sosfakeflash.wordpress.com/2...erfeit-drives/

    Anyhow these are the cards I ordered:

    Samsung 64GB EVO Class 10 microSD Card with Adapter
    Samsung 64GB EVO Class 10 microSD Card with Adapter - Walmart.com
    (Card made in Korea, adapter China. 10 yr warranty on SD, 1 yr on adapter.)
    (Samsung has a PRO series @ twice the speed.)

    These cards are formatted Exfat which cards over 32GB use (64-128GB currently). 635 is rated to handle up to a 128GB sd card.

    I purchased several 64GB Evo's cards and tested with with a windows app h2testw that writes and verifies as many 1GB files in succession as there is available space on the card. IIRC a 64GB card formats to 59GB so 59 files.

    Anyhow I tested each card for 72 HOURS on a MicroCenter TW700 Win8 tablet. Tried them in a couple of Android devices with sucess.. so card appear functional.

    Stuck one of the cards in the Nokia 635... upon powering up I expected a notification a SD card was found. NOTHING.
    Navigating to settings>Storage Sense results in only free space of internal memory showing, Micro-SD card section is showing no sd card... and all the section below in which you can tell apps to store data on a SD card are greyed out.

    Searching the net the first solution is to "RESET" the device -which wipes out all data on the device (and may delete preexisting data on a SD inserted!!!!)
    *SEE NOTES BELOW ON WHY THIS IS DONE, and WHY I THINK THE REASON "STORAGE SENSE" is as dumb as they come!)

    Second option (IMO RIsky) was to remove the battery with device powered up and insert Sd while powered up, it being said OS would then recognize card... Problem with that such is not recommended AND the "fix" stopped working if you turned off the device..

    SO:
    Tried multiple resets. SOFT reset thru the OS, and HARD RESET via buttons:

    Make sure the battery fully charged
    Backup all your important data
    Power Off Your Nokia Lumia 635
    Press And Hold Volume Down + Power Key
    Release Buttons when device will vibrate.
    When you will see exclamation mark
    Press this sequence of keys: Volume Up -> Volume Down -> Power button -> Volume Down
    Device will start the reset process.

    ***************
    Reseting the phone didn't work for me.[ SD was still not showing as being present
    Looking on the net I saw one post saying right after the Nokia Lumia Experience TOS page? was displayed and you "ok'd" it SD card appeared.

    That didn't happen for me...
    (If I had to guess upon allowing the 635 to fully update prior to 8.10.14226.359 (Current as of 2015-07-11) that stage of the reset used to display but that no longer shows now.)

    Anyhow= SD card isn't working.

    Doing more searching I read posts on the 630 in which the SD card holder instead of being the conventional PUSH in, PUSH again to release has a different design- that you have to engage a "lock" before SD will read... and I read a tidbit about some SD slots being crooked /bent/distorted as a reason SD might not be showing.

    So removed battery, inspected the "Slide-in" type, held by fiction sd slot of the 635 and all looks good. Saw a post mentioning Nokia Care? (Service) center Googled around with the intent I'd drop it in their lap and let them fix this problem and bill MicroSoft /Nokia on this but it was late.

    Last option for the night was installing a app called FILES, by Microsoft Corporation that is in the Lumia Collection in the MS Store as I had read the FILES app was being reported to be able to "See" the files on the Sd card.

    Installed the FILES app and think I rebooted and "STORAGE SENSE" is now showing SD card is present and gives options that were previously greyed out.

    So that may be the fix for those whose SD isn't showing.

    If you have luck with the above, please do a detailed follow-up and post the above on other sites.
    Microsoft /and or Nokia doesn't seem to be doing anything to address this issue!

    Note: Everyone having the issue even if the above works for you should file a case /trouble ticket with Microsoft/Nokia...

    *************


    NOTES:

    In reading the very lacking manual for the 635 or during my travels on the net searching for info on "STORAGE SENSE".... the brain dead app not recognizing a installed Micro-SD card I saw mention of NEVER removing the SD once installed.

    I think the reason for this and why it is said you have to do a FULL RESET of the device which wipes everything out is Microsoft being paranoid about apps on the MS being pirated (You've got to be kidding-most apps are el-crap-ola on a stick, and are not worth "pirating"), and most likely the DRM folks have made sure that the SD is being ""encrypted at some point /they are "marking" the SD in some manner (Marrying the SD to the device)... So this requires a full reset... and that the "STORAGE SENSE" app isn't getting any confirmation such has occurred...

    Hence it doesn't see it...Until by chance you install the "Files" app.


    PS: When the brain dead Win 8 OS app "STORAGE SENSE" was not seeing the SDcard a app called SD Card Speed by Amaze Pictures v2.2 when a attempt was make to test the card gave a error code (duh) with a "Com" in it.
    (Should have written that down)
    With the SD card now appearing speed on the 64GB EVO is 16.11 Mps...
