Non Root Users: SD Card can create major issues if not kept up with

Ok so I have a samsung class 10 16Gb micro SD card in my sensation 4g, and as of the last 2 weeks I thought my phone was breaking and needed a new one because the old one kept restarting while trying to use navigation, pictures weren't loading in the gallery, and certain apps would just randomly force quit.
After 2 weeks of dealing with the crap and trying to fix it myself, went and got T-mobile to send me a warranty replacement, and In order to prep for my new device I decided to wipe my card and keep only pictures and music, because it was about 1.52 Gb from being full and I didn't know why the SD Maid app wasn't cleaning out the junk data from previous apps.
In the end with the newly formated memory card my phone works like new, so the warranty replacement is just going to help, because this one had a small screen scratch. Anyone noticing the similar symptoms to the stuff in bold should try to format their memory card, and do a factory reset, it might help

Thanks for the information! This is good to know. I also discovered something with the sd card, I also noticed similar symptoms on a cheap sd card I had got.then I had recently purchased a new one and it was a trusted brand and when I put it I'm my device the symptoms were gone! There is definitely something to this! Bottom line is best to buy a good trusted brand of sd card and not the bargain brand or it could cause trouble!

i had to repartition and reformat mine sd-card,
after 4EXT has told me partitions aren't alighned.

Thank you SO much, Guy. I've been having those exact same issues to a T. I was getting frustrated with having to find pictures via Astro, not gallery, and last night I got lost because Google Nav kept rebooting my phone. I was ready to huck it out the window. I will try this, and hope it helps!

One toolbox? you mean 17 tools app? can't comment on that.
When I was new to XDA & I had posted query regarding 32gb class 10 card, I was lambasted for the fact that it had been covered a zillion times. Basically if it is a class 10 card it has been said since the advent of this device forum that it will cause problems later if not sooner namely in terms of apps mysteriously disappearing etc. I did not have apps missing by themselves ever but my issue was if ever my phone switched off due to battery full drain then it was pure misery wherein the phone would constantly reboot no end & this was when class 10 cards were pretty expensive. Then what I did was formatted the SD card ""on the phone"" & been using the app 'apps2sd' by Sam Lu & it has a functionality wherein it shows apps when installed as a grey 'X' icon for those apps which can be moved to SD but should ideally not be moved & from the very beginning I have always made sure I never move such apps to the SD. Don't ever use apps like 'link2sd' which complicate things on A2 especially. The highlight is for the lambasting that I had got that I have to accept that class 10 card would never work, I have to state till date I am running the very same SD card without any issues whatsoever so.... in any case, follow what I have stated above, may work for you, I use Rom Toolbox Pro but so far I have not tinkered setting to increase catching speed function for SD. Best of luck. Also it had been said that all apps should necessarily be installed to internal phone memory only but I don't do that yet & I'm surviving.

My gfs fone wiz has genuine ics upgraded os.. i haven't touch its software she has 4 gb normal card, i mean no class mentioned but m pretty sure not c10.
What now..??
And thanks for reply sir

In that case, yet format the SD card on the phone by first backing up personal files to a computer then ensure that SD card is not selected as default storage location and then also never install any apps to SD.
I observed you're all across the boards plagued with multiple problems besides this such as extreme battery drain, no network etc etc, so if you're in warranty ask for a replacement, would bode better for you.

the situation with class 10 sdcards depends on your phone, if youre lucky then your phone will support class 10 cards without any issues.. i per se have never tried a class 10 card but my friend with an A2 has and even he doesnt have any problems. I have always used a Class 6, first one a sandisk 16gb one and now using a samsung 32gb. Class 10 cards are expensive than class 6 obviously but class 6 cards are hard to find at the actual price in the market here. i bought mine for a bargain price from a seller on Olx.
As for the apps on sdcard and phone, even i dont install any apps on the sdcard, just games so that even if my phone is connected to the laptop in Mass Storage mode i can still use my apps..

[Q] SD card not mounting, "blank or unsupported file system".

When I putt he SD into my phone (currently running Paranoid KANG droid 2.32) I actually get nothing more than an occasional "SD has been removed" message. However, when I put the card into my old OG droid (running Cyanogenmod 7) i get the "unsupported file system" error. This has happened before, and I just had to wait it out before the SD recovered on its own. It is not doing this now. (yes I am an idiot for still using it despite my 32 gigs of internal storage). I have a feeling it is formatted as RAW due to a formatting issue, but I can't get anything else (pc or other devices) to recognize the card, other than my OG droid. So what I want to know, is if there is a way to force mount the card, or give a PC control over the sdcard path and force mount it some way through the PC (effectively turning my phone into an external card reader, because traditional methods don't work). I need a workaround for this, because there are dozens of pictures of my family, puppies, and friends on it that I don't want to lose.

Back up the card of you can, it sounds like it's dying on you. This phone really s3ms to kill cards, I've already gone through 2 32gig cards.

I had a 32GB Sandisk Ultra MicroSD card, and by chatting with Sandisk support, I am going to exchange my dead card for a working card. BTW, while you can, salvage the data you can, because it starts out like that, before becoming completely unusable.

I've went through two SanDisk. They are easy to work with, just get the ball rolling on the replacement.
Like the others said, get your data backed up as soon as you can.

wow. so now not only am I not able to use my phone on tmobile's 4g, I also cannot have external storage because the phone destroys it? what a tremendously idiotic piece of crap.
does anyone know about any apps or pc software that would help me get my data back? I have the card reader but the pc wants to format the card and so does the phone. I need, like, mad rescue gear.
thanks!

Wow... You can't use it on someone else's 4g because it was designed for a different network.
Also I've not had any problems whatsoever with my external.

Had 4 of these cards for a year now and not one hiccup. I'd say whatever is happening to them, its something you are doing to crap them, not the vendors. ALways backup your critical data, but if you treat these cards properly they will work and last as well as any.

No, you CAN use it on someone elses network, just not T-mobile as it doesn't do hdspa+ 1700, 1900... There's even a bounty out for that elsewhere on xda, to enable these bands, I believe it's currently at over $200.
And no, I'm not doing crap to the SD card. I've had it for over two years, used it on a different phone before that, never did anything different and it just died out of the blue. I'm not a noob, I would know if I had done something to it.
You would be pretty pissed off too if all your data was deleted, the phone you spent many many hours working to pay for did not work and when you ask for help someone blames you instead of helping. But I guess it's easier to blame than to help out right?

I get that part. However, don't get mad that it doesn't work fully for the network is wasn't designed for. That was my biggest part. I know there's a bounty. However, its been up for forever and nothing has come of it. I can't stand seeing people gripe about this phone because its not literally magic. Verizon's stuff is locked down, always has been, probably always will. Its a different radio/modem/antenna set than the tmo and at&t versions. It was meant to run on Verizon's network. Period.

ROEHSOFT RAM-EXPANDER on Moto G 2013?

Hi,
I own a Moto G 2013 (XT1032) and it has been a great phone.
However lately i was feeling the phone a little slugglish and decided it was time to move to a custom ROM to see if it would help. I´m using CM13 nightlies and the phone feels more quicker.
However, i still feel the need of more RAM. When using some more heavy APP´s, i can´t switch between them without the system closes the previous APP.
I´ll give an example. Sometimes i play Pokemon Go which is a heavy APP but the phone handles it very well. However everything else on background seems to stop working or with a massive lag. Sometimes i receive Facebook messenger messages after 5 minutes someone send them. And when i check them, even for a second, when returning to Pokemon Go, it has already been closed and i have to wait it starts again.
I think this is related with lack of RAM and i saw this ROEHSOFT RAM-EXPANDER which claims it uses a virtual ram which can improves this issue. I never trusted these kind of app and most of the times they are useless. But it seems it´s a very popular app.
However it talks about using SD Card as virtual RAM but my Moto G doesn´t have SD card slot, so i don´t know if it will works with internal memory.
I´m concerning about an eventual premature internal memory degradation since it will be more used... Or maybe it will not?
Anyone has a experience with it on Moto G without a SD Card slot? Or in any other phone?

There is not sd card, i was thinking to bought 32gb card but do it really helps because can i move stuff to it from internal memory, like apps?
