[Q] Change sd card

Hi I have a problem with my new Defy. It comes with a 2 GB sd card. I wanted to change it for another 8GB sd card but when i do the change the mobile doesnt start! The motorola logo appears and after 5 seconds or so dissapears.
How can i change my sd card for another with bigger capacity?
Thanks in advance.

Sorry to ask, but you did format it?

Might be down to compatibility - alot of newer devices, especially smartphones, tend to prefer micro sd cards with faster speed ratings, eg class 6 or 10. If you've bought a cheap micro sd card, chances are it's a slow one and perhaps that's the reason your defy is choking on it?
At least you have your defy! Delivery of mine has been delayed due to the snow!

I have a class 2 8gb in mine. Doesn't cause any problems.

I have changed mine from 2GB to 8GB I have no problems.The Motorola Defy starts as usual.

Solved! The problem was the partition file system, FAT32. I just removed the partition and now all goes perfect.
Thank you very much.

[Q] Phone gets unresponsive

Hey guys,
Sometimes my phone does not wake up again from "sleep".
It just does nothing. I've got to pull the battery.
I don't know when it happens -> when it gets hot or not.
Solution ?
It is a rooted phone with leedroid.
S-ON
Tnx

LeeDroid seems to be the problem. Over the past few days I have seen a few posts like this one.

Ok, I just flashed another rom. Lets see what that gives.

I had the same problem with stock froyo, starburst and insertcoin, so I suspect the sd card as the culprit!

hey,
My SD card is the stock what came with it.
It is a scandisk 4gb class 4 card.
Just installed : [ROM][19/04][Sense2.1 GingerBread]InsertCoin CM7/A2SD+ v03 |Cam working
Still same problem
Other suggestions ? S-off maby ?
Can I access a log or something ?

Do you by any chance use smartass on setcpu or underclock to 128 mhz

No, no setcpu or anything else. Tried it one on my desire but then my phone froze even more.
Today it gets wors. It also freezes when i'm typing sms or scrolling trough pictures on my phone.
SD card issue ?

I have the same problem, both with the one that came with the phone (sandisk 4gb class2) and the new one (sandisk 16gb class6).
I ordered a Kingston 16gb class6, hope it is alright.

Are you sure it is the sd card that is causing the problem ?
I'm now running without sd card

Did you have any problem running without sd card?

I'm gonna check trough the day. About 5pm (gmt+1) I will tell you if its froze or not

The phone did not resets/crashed/freeze or anything.
I guess the problem is the SD-card.
I'm gonna go to the store and buy a 8gb class 4 card from Kingston.
Sandisk is crap apparently.

Before spending your money, do you have a button widget installed? You know, for turning on/off wifi-data-gps e.t.c.
Try uninstalling and see if there is any problem.

yes,
The powercontrol from htc
the 2G/3G button also from htc.
Since I removed the SD-card no freezes.
Those buttons are also here when my sd-card was out so ...
But tnx for the comment

Good news. I ordered a Kingston 16gb class4, hope it is o.k. too!

Ok, let me know !

Just arrived and I am disappointed by the speed. It is terribly slow, its write speed is less than 1,6mb/s!!!
Have you tested the card? What are your results when writing files?

External SD vs. cold temperatures (solved)

Guess this is mostly a canadian concern, but has anyone else's external SD mysteriously been deactivated when the phone is exposed to temperatures below freezing for relatively long periods of time ?
For example, taking a walk outside for +/- 30 minutes when the temperature is around -10°C (~ 14°F).
It behaves exactly as if it's being manually deactivated in Setting --> Storage.
The card comes back to life after leaving the phone untouched for 5 minutes on the table upon returning to "normal" room temperature (~ 21°C / 70°F).
Never encountered this issue with the exact same SD card in my good ol' GS1 (i9000m), so I'm wonderring if it's the GS3 that doesn't tolerate the cold very well of if it's my SD card that's getting old.
---
EDIT
It was indeed the external SD card that seemed to be the problem. Switched temporarily to a 16Gb SD from my old GS1 i9000m and couldn't reproduce. Have bought a Sandisk Ultra 64Gb Class 10 micro SD card since then and couldn't reproduce with it either.
Glad it's not the phone! :victory:

Re: External SD vs. cold temperatures
I've had stuff like this happen, (Canadian as well). I always thought it was due to moisture but it's never been a big issue
Sent from my SGH-I747 using xda premium

Normal Operating Temperatures for SD Cards are: -13ºF to 185ºF (-25ºC to 85ºC)
There's a possibility that the SIII can't read the SD cards under cold conditions?
I'm not 100% sure, as I've only owned my S3 for a week and a half, and still playing and tweaking it..
I also live in Canada (Montreal), so our weather conditions are about the same.. So i will let you know if i encounter this problem or not?
I would try to re-format your card?? maybe that will help??
Use the Panasonic SD Formatter Software for Windows, and then I format inside my S3 for best performance.
Try that, maybe it will help???

It's an issue when :
Your camera is set to record images/videos on that SD card and you want to use it
You meet someone on your way and want to show that person pictures you've taken

If you're courageous enough, go take a walk outside today, or this evening, and see if you can reproduce.
Temperature a freakin' cold enough for it to happen these days! lol

Also, it's been discussed that most people think that SanDisk Extreme III is the SD card for extreme temperatures.
Which brand? is it?

Lexar 16Gb ... class 6
But like I said, this exact same card used to be in my GS1 and never encountered this issue back then.

Re: External SD vs. cold temperatures
I had an issue last week where, when I was outside on a job site, my sd card became corrupted. Lost everything on it and the card was damaged so badly I couldn't even reformat it to get it working. Had to get a new card. Don't know if it was coincidental or not. It was only about -4 C.

Mine got corrupted as well the first time as I didn't expect this to happen.
I kept trying to access it up to a point where when it was available again it got corrupted.
Had to format it and lost everything.
Since then, when this happens, I let the phone sit for a while and never had data corruption since.
Still curious to know if this is phone or memory related...

It was indeed the external SD card that seemed to be the problem. Switched temporarily to a 16Gb SD from my old GS1 i9000m and couldn't reproduce. Have bought a Sandisk Ultra 64Gb Class 10 micro SD card since then and couldn't reproduce with it either.

sd card issues

Hi guys,
Fairly new to the tab s got one just over a wek ago, since have been having issues with anys sd card i put in it.
Firstly i used a scan disk 32gb class 10
, it worked ok but would randomly dissapear, and seemed to have issues withplaying 2k videos, eg being choppy
So i thought i would upgraxe to a 64gb samsung evo class 10 card, been having nothging but issues since .
first i put loads on it then my tablet wouldnt read it at all. I then formatted it to ex fat via windows , same issue .
i then formatted in the tabelt it self. Now it works for about 5 mins then it will show as nothing in there
in storage settings says it mounted and show the correct memory but when trying to use it via various apps
as empty .
Both cards work fine jn windows, and have been brought from officisl websites hence arent fake
Anyone have any idea
Im trying to hold off routing so i can use banking apps , but if that lets me axtually use it !

You could try a factory reset on the tablet to see if that helps. If it doesn't work, then you'll need to exchange the tablet and do a factory reset anyways, so it won't hurt to try that first. I'm using the same samsung card you mention and it's working fine.

I just left it how it came, exFAT.

Android doesn't support exfat- it's a Microsoft format for the most part. Format it as fat32 and it will work. These large size microSDXC cards are coming formatted exfat (which was designed for flash devices in mind) but isn't really supported well.
Use fat32
I just got a 64GB flash drive and played with formats to see if I could use exfat or f2fs but nope. Fat32

I don't think that's entirely true. Some android devices don't support exFAT, but from my experience most do these days. I'm currently using an exFAT card on my Tab S.

ok so i tried exfat and fat32 and both did similar things.
I then tried the same cards inside my microusb to micro sd adapter and they worked fine!
So i took it back to John Lewis, spoke to their technical support who didnt know a fat lot, they kept telling me this tablet
doesnt support that type of media, i then showed them it did by using the microusb adapter, we then tried it in the display unit and worked fine, they werent understanding that sometimes it works in my device and
others it wont.
They kept advising me not to just swop it as the samsung tab s wouldnt do what i wanted it to do (i knew it would) they eventually agreed to give me a full refund, so i did and just swopped it for a nexus 9 as i was torn up between getting the
2 when i brought the tab s.
Short story - i swopped my tab s for nexus 9, happy with it so far compared to the tab s.
Also means i have some tab s cases going space if anyone fancies buying them off me for dirt cheap, got the official case, and cheapo one and some extremeguard protectors etc... drop me a message if your interested. (in the uk )
Thanks for all the help guys

I'm having the same problem with my SM-T807T. Using an 64GB SanDisk formatted FAT32. I had it my nook before and it was fine (works on windows as well as my phone) but randomly stops working in the Tab S.

Sounds like the tab s struggles with certain types of sd cards mabye?
do you have a micro usb to micro sd adapter to test it on like i did? worked fine for me that way.
But i went to nexus 9 and so far im happy with it

Funny enough i had the same sd card in my phone (same brand/model/capacity) and that one works fine in the tab. My phone (galaxy note 2) reads both so i swapped them. Card was Team 64GB sdxc
The nexus is a no go for me, no sd card slot is a deal breacker. Plus the tab s screen is also unbeatable. I do a lot of reading and high res graphics so it's ideal for me.

Android, and this tablet support Exfat no problem.
And you'll want exfat if you want to put HD mkv files on your card larger then 4gb (fat32 limit).
When the tablet formats a new sdcard it does so in exfat.
Sorry to hear you went Nexus 9....

After reading this thread I'm starting to think maybe the S series has some micro SD hardware issues...
Mine is a totally different problem and so far i guess it hasn't affected me much i guess...
I have a SanDisk extreme 32 in mine that i used in my Note 3 and Phantom Vision Plus camera... it has worked flawlessly in those other devices... now, while installed in my Galaxy S 10.5 .... when i wake the screen i see a popup sometimes that says something about "SD card detected" ... as if i just inserted one ... but the damn thing has been in there for two weeks!?!?
So far none of the other problems listed here tho... plays all my 2K video files just fine... reads and writes with no problems... really fast as a matter of fact... i don't get it

For sure the Tab S is very picky about which SD cards it uses. When I upgrade from 64 to 128GB I'll definitely be going with a Samsung EVO/Pro or one of the new SanDisk branded cards just to be safe.

Quite right - not at all true. Android absolutely supports exFAT - that's the only format you can use over 32 GB - without using some sort of format utility...and even if that works, you can't store files over 4 GB in size (like my ripped Bluray videos). Android also supports NTFS, but SAMSUNG doesn't appear to.

So why does a 16GB Transcend card pre-formatted as FAT32 work, but a 64GB Samsung EVO ***EDIT _- IT NOW LOOKS AS IF THIS CARD IS A FAKE. The App SD Insight shows it as INVALID. The seller did not quible ; just refunded me! *** that comes pre-formatted as exFAT not work? I have had no end of little troubles, which at the bottom of it all seem to come down to this brand new SD card. The card works fine in my PC, and in a camera. I've no other Android with an SD card, having come from Nexus when the 9 was physically too big.
If I don't unmount the card before rebooting the tablet, it has decided that the card is damaged and will not do anything. When I asked it to format the card, all it did was wipe the file table - it only took a few seconds so it cannot have done anything else.
It comes to something when a Samsung tablet will not play ball with a Samsung micro SD card.

I don't really have an answer for you. I have been using a new 128 GB Sandisk card since day one (I assume it is exFAT, as I just put it in out of the box. I did no formatting or mounting) and I have had no problems whatsoever. Worked perfectly when I first booted and has worked like a champion ever since. I'm not seeing any of these problems.

Thanks for taking the time to reply. How frustrating this is... Since posting I have looked farther afield. There are all sorts of threads across various forums on the internet about SD cards suddenly not working in Samsung devices.

I had similar problems with My SanDisk Ultra 32 Gig card. I took it from my LG GPad 8.3 and deleted everything off it on my PC except my music folder, when I put the card in my Galaxy Tab S 10.5 it showed the card but I could not access my data, after a few reboots it worked for a while but was buggy and would stop working. What did work for me was copying off all my data and letting the tablet format the card, I then copied my data back to the card while it was in the tablet over USB. I have not had any issues since and it has been several weeks.

One of the main reasons for replacing LG G Pad 8.3 with Tab S were SD card unmount issues. Here it goes again. I tried two 64 GB SanDisk cards, formated FAT32 or exFAT, even zeroed out one card... The cards still stop working after heavy load from media scanner or reading large video file. The cards work fine in pc, other devices (S5, iBasso...) and even when connected to Tab S using external card reader and USB host cable.
My other cards (32 and 128 GB) exFat and FAT32 formatted SanDisk work fine in Tab S. So I'm trying to solve the issue by ordering 128 GB Samsung EVO card and hoping for the best...
EDIT: The 128 GB Samsung EVO card indeed fixed my issues - even watching large video file is fine.

I don't think it does format the card. WHen I did that in my tablet, it took a very few seconds - long enough to do a quick format i.e. clear the data area that tells you where files are, but nowhere near long enough to actually format the card. Therefore all it does is leave the card as teh same format it was beofre the command.

[Q] [Micro SD] Anyone having issues mounting a Lexar 32gb?

Hi guys,
I doubt I'm the only one here.
I got my G4 (h812 LMY47D)and im ecstatic about using my micro sd slot (S6 was the main deal breaker paying top dollars for more storage) but now I'm running into issues with my Class 10 micros sd from Lexar, This darn software does not want to mount the thing (tried several format including a full 40 minute format @ fat 32 default allocation).
The G4 detects an SD card but won't mount it. This thing works flawlessly on my old S3 so it has to be software related as using a cheap Kingston 1gb class 4 works fine.
Anyone else running into issues with their sd card?
Thanks for sharing any info or tips.

Just taught of leaving what got me to sort this out after playing around... Fun times :good:
After tinkering around with another SD card, the LG device formatted it to FAT16.
I've formatted the sd card using http://www.partitionwizard.com/free-partition-manager.html under FAT/Primary
It created a 4gb partition and left it the remaining untouch
Popped the SD on the G4 and it finally mounted the partition
Performed an erase via the phone 2x to make sure and the entire 32gb is now accessible.
Hope that helps others having mounting issues.

I have facing same problems with my 64 GB sandisk sd card on new LG G4
can you explain the procedure to make it work

I've been using an AData 128GB for the last month or so with no problems. I turned the phone on yesterday morning and for whatever reason it went straight to my home screen but locked up and took half a minute or so to unlock and then goes to the lack screen, then I also got a SD Card inserted notification, I figured nothing of it and ignored it. The micro sd runs fine on other devices (formatted as ex-fat) but it causes that issue on startup i mentioned above as long as it's in the phone and it also refuses to mount.

I'm using the SanDisk SDSDQUAN-200G-A4A 200GB ULTRA MICROSDXC UHS-I since 2.5 months ago formatted in exfat with 128k clusters which was what it was out of the package and it works fine.

SanDisk is the only one with something larger than 128GB at this point in time and notice it's 200GB instead of 256GB as size usually doubles in capacity, heard the 56GB was used for something else or maybe not usable. I have a new 200GB card in there now. There is a 512GB card coming soon from Microdia as well.

Problem sd Samsung evo 64gb
Hi,
I had the same problem with micro sd evo 64gb, I formatted to fat32 but I can't solved a problem and only when a erese older .avi file recorder with older Nokia a solved a problems and now my lg G4 work perfect with my sd evo 64gb, and so guys control file inside sd well.
