[Q] Root and SD card - Android Q&A, Help & Troubleshooting

Hi
I understand that in order to seamlessly use the 32gb SD card I have in my Android dongle as "proper" storage, I need to root the dongle. Is this so? I'm also a bit baffled by the availability of a 32gb SD, yet "buffering" still happens. Can't the SD card be used as a buffer?

Does the phone come with an SD card?

Just wondering if I should pick up a card beforehand or does the Evo 4G LTE come with one?
My phone did not come with an SD card. You'll have to buy one separately.
no sd card but that new 64gb card I put in sure is nice.
Short answer: NO. You will need to get yourself one. You can get a 64 GB microSD card that will fit perfectly and work.
Long answer: You don't really need one. Yes, it comes with 16GB of storage, which is partitioned into: about 2 GB for the system, about 2 GB for apps storage, and the rest (about 10 GB) is put into the "/sdcard" partition. It's not really an sdcard, but a fake sdcard. It looks like an SD card to Android. This is where you would put the regular stuff that you would put on a normal SD card. IF you put in your own microSD card, then it will be accessible via both paths "/sdcard2" or "/sdcard/ext_sd", as they both point to the same location. I have both my camera (and video) and music storage pointing to my "external" memory (all 64 GB). IF you do not put in your own memory card, then you can still access the internal storage over USB, but you will have to do so via MTP. Google that. Most modern PCs should have support in the OS.
So, in summary... relax. You don't need to get your own memory card right away. See first if you really need it.
no. no and no.

[Q] 32GB mSDHC card doesn't work?

So I have a 32GB microSD card that works perfectly in everything except my Atrix 4g. It didn't work in the stock ROM, doesn't work in CWM, and doesn't work in CM10. I put it in and it says "SD card possibly damaged, you may need to format" or something like that. So I do that, and when I tap format it just flashes some screen and then keeps showing the ongoing notification about how my SD card is damaged..
I tried FAT32 and exFAT, neither worked. Tried quick and full format for both. Any suggestions? Or does 32GB not work on the atrix?
Hmmm...
It may be that your SD slot is damaged, or the SD card/brand is not compatible. I have a 32GB card in mine that works perfectly. If other SD cards(2,8,16GB) work, then I'd try another brand of 32GB SD card, if no others work, then the slot is probably the issue.
Hope that helps.

Have you tried a different MicroSD card in your Atrix? I remember reading that the MicroSD slot gets loose and stops reading cards. If your current card works fine in other devices, try a different card in your atrix.

None of the ones I tried worked. Is there any known issue with the SD slot that's an easy fix or am I screwed unless I want to open it up and do some soldering?
Are you sure you are not trying to put 32GB SDXC card? I don't see how 32GB SDHC any different from for say 8GB SDHC.

[Q] Swapping Internal and External SD

Has anyone tried switching the internal and external sd cards in the fstab? If so, could I see your void.fstab?
I want to fully use the 64GB microSD card I just ordered. It hasn't arrived yet, so I can't test it myself right now...

[Q] Inserting micro sd breaks phone external storage

Ok so I have never heard of this one before and I have tried looking for an answer.
My S2 works perfect when it has no micro sd inserted but the moment I put in a micro sd card the phone will boot ok but then it will not recognize any of the phone external storage (the 16gb bit) I get an mtp application has stopped error and I cannot access anything with any file managers not internal storage, external storage, or micro sd. The micro sd doesn't even show up and the rest show all directories as empty. I have this problem exactly the same if I flash a custom rom or stock rom rooted or unrooted it makes no difference. Anyone have any ideas? I have tried different sd cards but they all cause the same problem. I have tried reformatting the sd card also.
Flash dorimanx kernel version for the ROM you're on and test. Also formatting int sd card may help with this. Bk up you're data. format it and test.

Show micro sd card connected to phone as an external sd card on pc.

Hi, I bought this raspberry pi 3 model b and I heard that you need an external micro sd card to boot from. I do have a 32gb micro sdcard that is class 4 which is excellent for use in a raspberry. But, my pc does not have a port for micro sd cards and I wonder (because I used to transfer files via my phone to get it to the sdcard) if there is a way to make the phones sdcard show up as another device (external storage) on the pc. All my android devices have superuser acces if that is needed. If anyone has any questions, please don't hesitate to contact me via pm or this thread.
Btw, I am not planning to buy a sdcard reader but if that is the only option I will do it.
