Milestone 2 with 16GB C10 TF card

[littlekp]

hi, I have bought a Class 10 Micro SD card for my milestone 2 today.
But I found the screen will running out after locking from both button and time out. And the system will run slow down after boot up immediately. Anyone have the same situation and I would like to know is not supporting 16GB card, or brand (A-data), or Class 10 (too fast??).

Thank you and sorry for my English...

I have a 32GB class 2 card (Sandisk). Much as with yours, the system runs slowly for a brief time after startup (an icon displays in the status bar displays saying that the SD card is being prepared during this time). I think it's normal, though if it continues for more than about 30 seconds I'd say there might be a problem...

My screen timeouts etc are normal. Does this only happen when your MicroSD is inserted?

 

[littlekp]

yes, this problem only takes place when I put the Class 10 card into the phone.
The blank screen shows up after once the screen locked.

It makes me frustrated as I bought the card and hope I can enjoy it.
But the error checking is super fast although I got 4GB small files inside.

Update: When I put the blank card in, it seems works fine...

An 16gb transcend class6 microsdhc card works on my phone not correctly. If the system write on the sdcard, the system hangs and work very slow. An class4 card from sandisk works very fine.

Exactly the same problem here. I bought a 16GB Transcend Class 6 card and I have problems all the time. The phone hangs and only battery pull helps. Titanium /Backup is slow and hags, etc., etc.

hey bros, I found the issue may be caused by the card slot. The card is working fine on the phone.

What do you mean?

Hey guys,

i've had the same problem with my Milestone 2.

I think i found a fix :

Simply format the sd card while in your phone with the built in "format" found in "settings".

!Dont! format the sd card with your PC !

Did that with mine and my phone is running perfectly now.

I thought about it. I am going to try it too.

I just formatted the card in my phone and put the data back on.

I did a quick test - tried backing up my stuff in TiB. No luck it still hang like it did before.

thank

I was to help this discussion ... I had the problem with a memory of 32 GB then decided to go to 16 gb and all perfect ...!

my card is working now suddenly on one day I put it back on the phone to test again.

I think this problem is caused by the design of the card slot which may lead incorrect touch of the contact surface between phone and card.

Hi, sorry for ressurecting this thread, but I believe I found a solution:

Put your high class cards on the phone and boot it up. On rootexplorer, go to /sys/device/virtual/dbi/179:0 and /sys/device/virtual/dbi/179:32, longpress read_ahead_kb and choose edit as text file. You'll see a value of 128. Change to 1024. Save and exit. Test if your cards are still missbehaving. I saw it on a EVO tutorial, tried here and my 16gb class 10 card worked normally. The only problem is that you have to do it every time your phone reboots.

Got same problem here with a class 2 16 gb

 

[jetbruceli]

Same issue but I have used a 32gb class 4 and it was fine. My 32gb broke and I put back in the 8gb class 4. Its fine too! I just bought a 16gb Adata class 10 and its giving me the same problems as you guys but its only when i use more than 3 gb of information. So I think the phone cant handle class 10 cards

If problems starts when you use more than xxxx GB, maybe it´s a fake capacity card.

Make sure to check the SD on pc with h2test to see if it´s fake or not.
