Mediascanner wakelocks driving me nuts

Anytime an SD card is inserted into the phone, I start getting Mediascanner partial wakelocks that are hurting battery life. If I eject the SD card, time awake = screen-on time almost perfectly. I deleted all the files from the card and reformatted and still get the same scanner wakelocks. Seems like this has to be an error in the OS? Card is a 32gb Sandisk Ultra.

I had this issue. Eventually I found out it was a corrupt file. So I took everything off, formatted and started from scratch.

As I mentioned above, wakelocks continued when only a blank newly formatted sd card was inserted into the phone.

Do you have another sd card lying around to try and see if it your sd card?

I am testing it now with a blank reformatted 16G Samsung SD card I had from my Epic 4G.

Interesting. So far the problem does not seem to be occurring with the Samsung SD card (at least with no files on it). I will monitor it for a while today and add a few files to see what happens.

I loaded a couple of movies to the 16G Samsung card and still no problem.
For some reason, the phone does not like the 32G Sandisk Ultra.

The samsung is fat32. I tried the Sandisk on both fat32 and efat with the same result. The phone has some issue with the sandisk.

Glad you found the issue. Stinks the issue was with the card.

From doing some more searching, it seems like others might be3 having issues with the Sandisk 32g as well.

Battery life is much better now that phone is sleeping again.

There is an app in the playstore that runns a script that disables the media scan after the first one It is called media rescan root

Since the issue seems to be the card, I wilo just stick with the samsung card for now. Thanks thought.

My Note II keeps remounting SD Card

Hi
Sometimes when I turn on the screen I notice the SD Card symbol is "ON" in the notification bar. Is it because my Note II keeps remounting the SD Card and thus rescanning the SD Card?
Why does it keep doing this?
I have my songs all stored on the SD Card and because it keeps remounting it, the songs do not stay in the playlist!
How do I keep the SD Card permanently mounted?
My Note II is running stock ROM.

Nope... plugged and unplugged by SD Card a number of times and still the SD card gets rescanned.
Can't keep my songs on SD Card in my playlists.
Does any one else experience this at all? Am I the only one experiencing this?

I have the same issue. Till now, not able to find a solution. Planning to send it back for warranty claim!

This is a warning that your sd card may soon be destroyed. It afflicts s3 and note 2. just backup your data. For more info search the thread- "s3 the sd card destroyer"​

I had a 32gig scandisk class 10 and it kept re mounting every so often... also sometimes my pictures wouldn't show up in gallery. Tonight I bought a Samsung 32 gig class 6 and all is well.
I believe it was the stupid scandisk that didn't want work properly. Hope this helps!!!

Had the same problem, my supplier gave me a new card, problem solved

the same with a 32gb sandisk class10, after ~2 moths of use without a problem.
Amazon gave me back the money and my old 4gb card is working fine.

I had encountered the same issue with my n7000 and my s3. Your SD card is on the way out. Try to format it first but it that doesn't work your best course of action is to replace.

Guess what? My 32GB Class 4 SanDisk went all flaky a couple of days ago. I got an error message saying that the SD cannot be read and to reformat it.
Absolutely not! All my new pictures and songs are all being stored on the SD card!
I rebooted my phone and it could read the ca4d again but it's no longer stable.
Sigh
Why do we have this problem with the Note II?

The memory cards have been a problem.

I've experienced the same issue once on my Note 2 with a Sandisk 32Gb card.

My 32GB class 4 Sandisk microSD card that I thought was working well finally died. I tried reformatting it and it worked for a little while more but finally died and could not even be reformated.
What can we do about the Note II propensity to kill microSD cards?
Sent from my GT-N7105 using xda app-developers app

Damn, I really hope it's not the Note 2 that's killing cards. I just sent back my 64gb SanDisk card which died after about 4 months of use. So while I'm waiting for a replacement, I have a 32gb cards in the way.
In over ten years of using removable flash storage I've never had a card die in me and I've had at least 15 different CF, SD and micro sd cards. Why does this "high end" sandisk card have so many issues on modern devices?
Sent from my Galaxy Note 2 using Tapatalk 2

My 8gb class 4 Kingston card also died while being used on my Note 2. Was previously using the same card on s2 and s3 too. I'm hoping with all these reported cases of sd cards dying, correlation doesn't equal causation! I'll nevertheless get a Samsung sd card for replacement. Hoping samsung cards should theoretically work better on samsung phones. Haha

I have got same problem on my 32 GB class 10 memory card and got it replaced.though I got a brand new sd card but still confused o using it.... wheyher I shuld use it or get it change with samsung 32gb class.any advice would be great

[Q] Which SD cards have been reported to work with the Note 2?

I know there are numerous issues with 4.1.2 with the Note 2 and the S3 concerning the micro SD card. Right now I have a 2GB (no idea what the class is) SanDisk card in my note 2. I bought a 16GB class 10 lexar, and one day later I got the mounting issues where the phone would keep mounting and unmounting the card. Couple of days later, the card was totally unreadable by the phone. So I decided to take it out and thankfully it was still readable on the computer, so I gave it to a friend, where the card works flawlessly on her BB. Anyway, I've read around that the samsung cards have been solving this issue... Is this true? I am definelty staying away from SanDisk and Lexar as those are the two clear brands with problems. Anyway thanks for any help in advance!

I've been running a 32gb PNY SD card for months. Bought when I had my S2 then used it in my S3, did have an isuue with it on my S3 when I made a backup of the rom I was using but was able to completely restore it. Put it in my Note 2 when I got it back in April all has been good so far.

The red/grey sandisk cards in 8, 16, 32 and 64 gig capacities run fine. Rocking the 64 at the moment.

I had read somewhere a few months back that the Sandisk cards had issues with getting hot and failing but if I remember right it was the black class 10 onesthat where 16gb and higher. Something about them not being able to handle the faster read/write speeds in the S3 and probaly in the Note 2. I'm very happy with my class 10 32gb PNY.

Wow, a lot of you use the SanDisk which I am trying to avoid haha. Maybe I'll go for the Samsung cards. I don't understand why there hasn't been an update yet. Frying a memory card is a big deal in my point of view...

Note II SD question

Hi there again! I just wanted to know if there is any special requirements for sd cards for use in note 2? I mean can I use any kind of micro sd card, old ones? few days ago I posted a question about my note 2s screen going black... I sent it for repair but the guy told me after some days that he turned the phone on and after 2 or 3 days and there were no problems...that maybe the sd card I was using cold be the problem... it is a 4gb micro sd card and actually its workin fine in my other phone...xperia mini pro...
Thanks in advance if someone could confirm this!!

Class 10 and any card class 10 that's compatible with new phones have fun
Sent from my GT-N7100 using Tapatalk

No theres not any special requirement for a micro sd card for note 2.Even a class 4 would suffice.Although to get better performance you can go for class 6 and up.
I have also used a card that I used for my nokia n81 and nokia 5800 4-5 years back and it was a class 4 card.
