U8100 lockup new microsd - Android Software/Hacking General [Developers Only]

I just bought a new 16GB microsd card for my Huawei U8100. Since I got it my phone has been lagging. It would constantly freeze, especially when switching to next song in the music player.
I checked to see if it is fake, but it is real, has full 16GB at class 6. I first noticed the problem when using a custom ROm with swap and ext partitions on it, phone was incredibly slow, now it is bearable when I used the swapper app.
What can I do? Is the microsd card broken? I checked and it says my phone can handle 16GB, no idea what is going on here.

[extend memory] Bricked HTC 7 Pro

Hey,
i screwed it up somehow. my phone doesn't work anymore.
After installing the memory card and a hard reset it stops working during the installation.
it just says:
Code:
"INSTALLING APPS
A few more applications still need to finish installing. It should just take another moment or two."
i wait 40mins before i removed the batterie.
after this i try to restore my phone with zune to the NoDo restore point.
failed with error code: 80180090
But the phone restarts normally and my phone recognizes the 16Gb card.
but it doesn't feel smooth anymore. (for example it takes a long time to start enter the settings)
i was also able to connect my phone to zune.
Zune recognizes my sd card as well but when i try to sync Musik it throws an error (C00D124D) after a few songs.
it tryed a softreset but the result is still the same.
right now it shows the
Code:
"INSTALLING APPS
A few more applications still need to finish installing. It should just take another moment or two."
again
it is a vicious circle...
any other ideas?

Newegg's comments on the microSD 32 GB cards they offer rate the cards very low in general. Appearently quality assurance on these cards, or the cards themselves, are extremely flaky. Put the card in your PC and run a stress tester on it.
As for your original 16 GB that seems to be worse, try a hard reset. When changing the cards around, that could have something to do with it.
I used the 32GB card linked in my sig. It actually came in a red package that says for mobile devices. It also appears to be the EXACT same card as the 16GB that came in the phonem only difference is the capacity.
0 issues whatsoever, seems every bit as fast as stock if not a bit faster.
I had such problem with my old 16Gb Kingston Class 2. There were no any problems with installing apps, but phone was not smooth. And there were some problems with syncing Music, it was taken a long of time, and sometimes there were problems during the process.
So, I've installed my original SD 8Gb card, made another hard reset. Now it looks smooth and sync is fast. I decided not to change card anymore, but buy mp3 player with 32 or 64 Gb of memory. Because I don't like how this phone is playing music.
I've purchased a Wintech 32 GB microSD card from Newegg and plan on installing it in this, when I get my tri-wing screw driver set. So I'll let you know how that turns out.
Until then, I've ran just about every stress test I can find against it - and it has no issues. Note: I am not going to do a full format like others are, that seem to have issues in the long run. I am going to use it as the card came.
EDIT: Don't buy the Wintech for WP7.
i managed to bring my phone back to life by simply replacing the new card (Toshiba microSD card 16GB class 4) with the original card.
But 8 GB is a mess i will try it later with another sdcard.
Did anyone could recommend a 16GB/32GB card from a retailer in germany/europe?
Joel
For the record, I had issues as well with my 32 GB upgrade.
After some research, I now see that you should not be getting the highest class card. You need to focus on random access times. The Sandisk 32 GB microSDHC really is the card to get perhaps. Still a bet.
I'm ebaying my Wintect 32 GB class 10 to some Android user. For our WP7, it's all about how quickly you can find the fragmented data - not how fast you can read the data. Think, "need to find it fast enough, or the phone will reboot".

Does anyone have problems with the 8gb micro sd with 3gb or less free?

Like what problem?
Yes. What kind of problems. I have 2GB free and use to have less.
maybe he mean does we hava anything wrong with that case.
my problems are:
i have the original microsd 8gb class 2 when i put some videos, music or pictures and the capacity it's over 5gb, when i restart the phone the "preparing microsd" notification doesnt dissapear and i never take the phone control back except when i release the battery and put it back and change the microsd.
I've bought microsd 8gb class 4 and the same happens.
it's there any solution?
i'm using 4gb class 6 and no problems but i need more space.
Your problem is the SDCArd in general, I was nearly trowing away my XT720, bought an new SD card from ADATA and same problem. My last hope was an new Quality SDcard now with a "Samsung Micro-SDHC 16GB Class 10 - Plus-Serie MB-MPAGA" I have a new phone , no errors, no restarts, didient have to "battary reset" since i have that card.
The investment in a good SDCARD is (IMHO) the best you can do to your phone.

minor glitches when playing video from external SD card (Sandisk 16GB)

When I play video stored on my internal storage, it is smooth. I can watch a 90 minute movie video without noticing any glitch at all.
When I play video stored on my external storage, there are glitches. One glitch every 1-2 minutes. These are not big glitches, just a brief deviation that gets your attention. If I listen, I think it is skipping a fraction of a second of the audio. (It may be skipping a fraction or second of the video display also, but my eye doesn't detect it). It's not a huge deal: ...... but just something that I notice and it's a minor irritation.
Since it occurs only on external sd, not internal storage, I assume it is the speed of the sd card. I have a 16GB Sandisk SD card. If I remember right, it's "Class 6"
I don't hear any glitches when listening to MP3's off of external sd, works just fine with no glitch ever.
SUMMARY: no problems on internal sd, no problems on mp3's. The only problems are videos on external sd.
It seems to me that the external sd can't quite keep up with the high transfer rate required for video playback.
Has anyone else seen this?
Any observation about which SD cards do this and which don't?
By the way I'm running rooted 2.3.6 from qkster's package, with Zen's Infusion A kernel. Holo launcher.
I haven't tried boosting to 1600Mhz. I'll try that and report the results later.

I just tried it - no difference. Glitches still occurred with cpu max frequency set to 1600.
You should try to format your external card and then try again.
Also, it could be your external card is to slow on reading
Should not be that slow if it is class 6 though...
Maybe try other card on your infuse with same video file.

Thanks. I have also noted the SD card media scanner runs to scan my external sd card more frequently... almost every time the phone comes out of sleep. I think this symptom coincides with me adding more files to my external SD.
I will try reformatting now as you recommended.
Question: is it better to reformat sd card in the phone or on the pc?
(if on the phone, there is no question of file system... I'll let the phone pick the format. If on pc, I'm not sure what format to pick... I'm using Entropy's kernel with voodoo lagfix enabled... does that mean external cannot be formatted to FAT32? )
The bigger problem is the constant scanning every time I turn the screen on. It was a nuisance, and I think it was draining my battery.
It gave the error message "sd card unexpectedly removed".
There are threads on this for some other Samsung devices.

There was a suggestion Sandisk cards in Samsung devices tend to have the problem.
I transferred my files to my pc, formatted sd in the phone, no problem until I transferred files back... then problem started recurring.
I reformatted in the PC to Fat32. Put files back on. Seems to be much better. But very close monitoring using SD Card Monitor program....

... shows it is still have problems. I'm going to break down and buy another sd card. Perhaps another brand.

Your SD card has problem for sure.
It shouldn't scan that often and it shouldn't say it is unexpectedly removed.
Seems either phone's card reader or the card is very unstable. That is why you are having problems in video files.
If the SD card benchmark program shows that tour SD card is performing bad, I beehive you got fake Sandisk SD card or really low class SD card.
From this point, I believe getting new SD card is the best solution here.
PS. You should put the SD card on PC then run benchmark on PC to see how it performs on PC. If it performs too much faster on PC, then the problem might be your phone's card reader.

Symptom went away with new sd
Before replacing the sd card, I had 100+ sd card events recorded by theSD Card Monitor program in a 24 hours period.
After replacing the sd card, I have 0 events recorded by the SD Card Monitor program in a 24-hour period.
The new SD is a Lexar 32GB Class 10 for $45 at Target. (preformatted as FAT32)
It was cheaper than the $70 32GB SanDisk they're selling at Best Buy.
I'm tempted to say the problem is solved.
On the other hand, one thing I noticed on the old SD was that the old sd symptoms got worse with time... I don't think they were there when the card was new. So I'm not sure if I've really solved the problem or just reset the clock waiting for the new SD to act up under whatever influences degraded the old one. Time will tell. For the time being, life is good. That scanning upon coming out of sleep was a real PITA.. slowed down the phone just when you picked it up to use it... actually dropped two phone calls recieved while phone was sleeping.. I presume because the phone wasn't able to handle scanning and answering at the same time.
Perhaps it was a fake SanDisk. Where'd you buy it from? Lots of fakes on eBay.
I bought the SanDisk (that had the problems) at Best Buy.

what's wrong with my SD card

I bought this SD card from amazon
Sandisk Ultra 32GB Class 10 Micro SD Card with SD Adapter
http://www.amazon.co.uk/gp/product/B007JTKLEK/ref=noref?ie=UTF8&psc=1&s=computers
formated by 4ext, has 1 EXT4 with 1GB/512MB, rest are FAT32. Installed VJ CM10.1 5.1 ROM, a2sd YNY. Nightmare came after phone booted, it's fast, but randomly "DEAD". "DEAD" mean phone totally freezed, no response at all, include all keys and screen. Have to remove the battery to restart....
I changed back to my old Class4 sd card. Did some test on this new class10 SD card, has no problem at all.
Is it because it's 32GB? Should I use a 8GB instead? Please help.
Hello!
I'm not sure, but i read alot about people getting trouble with a 32gb SD. Maybe do the partition again, something might have gone wrong.
Hope it helps,
- Rinse
Hello,
The first partition must be FAT32, than you can create the second partition in EXT4 format, I think.
Insert in pc, restore to defaults, format, then do as you please!
Huh, strange - I have same card, but 16GB.
In my tablet it is working without a problem. But in desire - I was trying for 5 days to make it working - without luck Random freezes, FC, phone dead (had to remove battery to power it on).
I tried diffrent roms - didn't work. Tried to format it (in 4ext), zero it (on pc with card reader), partition it again with diffrrent partition sizes (1.5GB, 1GB, 512MB) - nope.
Card is ok (as I said - in tablet it's working) - but my desire don't like it So I'm still on 2GB class -500 and thinking what to buy (8GB class 10 ? what manufacturer - adata, kingston? )
is 32gb working on htc desire?
SanDisk cards are known to cause the problems you described with the HTC Desire. I had a SanDisk 8 GB card too, and exactly the same problems... the solution is to not use SanDisk cards.

No it ain't...... My Desire lags as hell when I use the 32 GB class 10 Kingston card... Works on my QMobile Q3i.... Dunno how...
are you sure UHS-1 cards like these sandisk ultra are compatible with desire ?
Hi,
I'm using a sandisk card too, i do have a lot of problems with my HTC Desire.. can't use the phone anymore for daily use.
Freeze by phone calls, have to reboot 3 times before it's good and well started up.
Maybe SanDisk is the problem? Can someone confirm this? But why do they liver SanDisk by buying the phone then?
I have Samsung class 10 card and it works realy good.

Hi there,
I have the same problems with SanDisk 4GB class 6. The trick is do not use app2sd.
I want also know if other cards like kingston do have the same problem.
Now i'm using VJ 4.1.2 with sd-card fat32 and no apps installed. At this moment there are no problems with my phone.!

I have the same card I picked up last fall and have the same problem. I'm going to try it out in a DSLR to see if it works there. My old card is a class 8 Adata (I think, might be Kingston) and started to randomly corrupt the fat partition, loosing all data and requiring a full reformat (which is why I got the Sandisk in the first place). So I can use a card that makes my phone completely useless as a phone or use a card that randomly looses all of my data. I should probably get a new card. On the upside I have become prolific at backing up my data. Also worth noting is that the Sandisk card is fast while it's runing.
I'm using SanDisk ultra 16gb uhs-1 for a couple of months now, didn't have any such trouble. could pvt version of desire be connected with that? Mine is pvt3
I'm also pvt3. I'm also rooted, s-off, use a2sd, no change with mounts2sd, and tried different ROMs (ICS, JB 4.1 & 4.2).
It seemed to only happen while using a heavy app if the phone was bogged down with multiple apps. To rule out a power supply voltage drop I replaced the battery. Although replacing my two year old battery was a good upgrade, it did not fix
the issue.
Everything I've tried points to a SD card issue so it is interesting to hear that it may only effect the 32GB UHS-1 cards. Samsung isn't as readily available around here so I may try the 16GB version but I'd prefer the upgrade to 32GB capacity. The card was phenomenally fast while the phone remained stable so I'd take speed over capacity. I just haven't seen mention of this problem with other 32GB cards.

If partitioning with 4ext recovery and cleaning the sd port in your phone (blow some compressed air into it, with phone powered off and let it regain normal temperature before powering back on) won't help, try sending the card back to SanDisk, in my country they give lifetime warranty for their cards. But first you gotta make sure your desire is intact hardware wise.
You might also test your card with tools like crystal disk mark and see if it gives up when strained.

Exactly that was my experience.
I got the SanDisk (Class 2, 4GB) which came along with the HTC Desire and bought a new SanDisk for mobile devices a few months ago (Class 6, 8GB). Both are working fine if I don't partitoning the cards/don't use A2SD - the phone won't freeze, etc.
If I partition these cards (method doesn't matter, tried CWM, GParted and another tool [don't know the name]) the phone is going to freeze randomly and on 2G network every time. My HTC Desire is PVT1. I rooted and flashed two PVT3 and one PVT4 devices as well and aligned their cards - no problems at all. No freezes, everything is running pretty good. So I have no idea.
The last months my phone barely run, it was freezing all the time. Even some ROMs which were running very great 2 years ago didn't run again (My boyfrriend said the problems occured because I was flashing it too often... But I can't believe that ).
I wasn't able to figure out what's wrong, so I decided to buy a HTC One.
I guess it's some hardware related issue?

Anybody using a 128 GB Micro SD card in the Z3?

Hi,
I bought a San Disk Class 10 128gb Micro SDXC card the other day on amazon.
I put about 40 gb of music on it and it seemed to work fine. Everything was fast and fluid. I then added more to where I had about 90 gb of music on the card. After that, I noticed the music menu on Walkman was taking a long time to load. When I would click on an artist, it would take a few seconds and then show the albums/songs.
Now, the phone completely freezes up if I open the walkman app, or even try to open Photos with the SD card in. I tried putting the SD card in my Surface Pro 3, and everything loaded fine, and quickly. My other SD card (64GB San Disk) didn't have any kind of issues with loading things up. Anyone have any advice with this? You think my card is busted?
Could be an issue with the android version, I'm waiting for lollipop since it "fixes" what Google changed with SD card compatibility. On my old m8 the sd card kept corrupting and when it was working the music would sometimes not play although sometimes it would, some pictures wouldn't show up. I then got it replaced and the same thing happened.
I have both the Sandisk and Lexar 128GB cards, both work fine. What may be happening is you're overloading the process that catalogs the info on the drive. Try clearing the data and cache for Media Storage and Walkman apps.
I've used the Sandisk 128GB micro sdxc for a couple of months and had the same problem.
I'm now using a Samsung 128GB Pro and i've not encountered that problem since (about five weeks now).
Will update in a month or two if I encounter any problems with the Samsung card

I have the sandisk 128gb micro sdxc card as well. been using it for 2 months with no issues noted. having said that i only have 1.5gb of music and the card is only around 29gb full.
I use Neutron as my music player won't touch Walkman sorry. If Walkman is anything like Album it sucks. My card cost ~$115 so I do not expect any problems.
