Lingering EVO issues (SD Card, Camera, etc.)

I'm having some lingering issues with my EVO even after running OTA updates. I am running a rooted stock ROM, currently software version 1.32.651.6 (I have not attempted the latest OTA update yet).
In particular are two problems - SD card issues have remained even after the OTA update. This was present even before rooting but after installing the first update (I went to a "full-service" store on opening day and they set it up themselves, assuming everyone would want it - luckily I could still get root). Issues include the Camera application reporting permissions problems randomly when trying to save pictures to the SD card, HTC's music application freaking out and coming to a near freeze trying to crawl the SD card during one of its troublesome spurts, and files disappearing from file explorers. So basically run of the mill, pre-first-OTA sd card problems. But occurring after the update and both before/after rooting.
Second is a problem with the camera itself. When first booting, HTC's included photo/video application will instantly crash after showing the camera icon on the black background. Google Goggles freezes for about 10 seconds then reports it was unable to connect to the camera. After the phone being on for about half an hour, these issues (seemingly) go away until the next reboot.
Last, and least frequent but still troubling, is a problem with the device powering on. At least twice I have been unable to get the device to turn on after powering it off, forcing a pull and replace of the battery to get it working again.
As far as I know, all of these issues could be either hardware or software. Even the power problem - my best guess is that the phone never powers off fully, but is instead locked inside of a deep sleep state and thus can not turn on until a battery pull forces the entire system off.
The questions being - first, are there any known solutions to the above problems? I have found many threads in particular regarding SD card issues, but none that seem to report these problems post-update. The others I have seen little to nothing about.
Second - if there are not known solutions, would it be prudent to return the phone as it may likely be a hardware problem?
Since it seems I'm forced to take the last update if I get a replacement, I may likely have problems getting a full root back. I'd like to avoid that if possible - having root works wonders for doing application development using non-native (unexposed) API's (Which - side note - since I'm developing for 2.1 at the moment, other than hacking for direct access to a Surface, does anyone know of a _fast_ way to do direct blits from native code? glTexImage2d is insanely slow).
Thanks all any help. Again, apologize if any of these are solved and gone problems, but I wasn't able to procure anything myself.

I'd go for the replacement, sounds like a defective unit..
Be sure that the folks here at xda will get root working regardless of OTA.

replace the unit, i'm very particular about my phones, if there is anything wrong with it I replace it.

I too have the SD card issue, I have updated, i have rooted, re-rooted, flashed new rom, different roms (fresh and sd) and it has always given me the sd card issue. Sometimes it wants to be a pain and not work at all, sometimes its good for at least a week or two. I am waiting for a little longer to make sure when I get a replacement its a newer version.

SD card permission errors --- POSSIBLE FIX
I hope/think/believe I fixed this error for those interested, I use my EVO for work and need it to work without a hitch....
Here goes (**Note i am a noob with smartphones with a dangerous amount of IT knowledge - disclaimer for those brave enough to browse around the root files and SD card files; I am not responsible for you bricking your phone, I am only trying to help those in need and putting in my 2 cents_)
Download and open the app ---> Root Explorer (or any other root explorer for that matter) from Android market.
Once Root Explorer is open (look up top/left it will say) Mounted as r/o (means read only) - press the white button to mount it as r/w (read & write)
Press and long hold on the SD card directory (folder) - you will get another window from which you must select the permissions option.
Under top option USER - check all marks -- READ WRITE AND EXECUTE & click OK.
VERY IMPORTANT - Click on the (white button) Mount as r/o to write protect your root files on your phone again.
I just applied this fix about 45 mins ago and seems to be working......updates to come if issues persist or re-surface. (**Note I could not see photos or play music and some apps were also giving me FCs (intermittently) due to permission or write errors to SD card; and now it seems to be working like nothing ever happened.)
What I have ::: stock ROM on EVO supersonic with recent HTC updates applied - standard 8Gig SD card provided with phone / had rooted but put back stock ROM for preference issues.
Hope this info helps some folks...very frustrating issue.
Cheers

SD card permission errors --- POSSIBLE FIX
ONE LAST SIDENOTE COMMENT -
I transfer data to my PC often (running Win 7 32bit_)
It is crucial that you right click on "safely remove hardware" icon on the lower right side (next to date and time) and WAIT until windows tells you
..."It is now safe to remove your hardware" --- I was just taking the plug out when done and it appears as if that could have started or compounded these issues with the SD card.

I too get the could not connect problems at times. And I have lost access to the SD card a few times. Some say its Fring that causes the problem. But after removing it I still have camera issues. I noticed that having the LED Light on while trying to open the camera will cause this problem.
I am running CM6 RC1 so this is to be expected from Release Candidates. Sit tight. It will get fixed.

Well after a full 24 hrs...no issues with the read write error on my EVO SD card, I think that when the phone is removed from PC incorrectly (i.e. pulling USB cable out in mode other than "Charge only" i.e. HTC sync, Disk Drive, Internet sharing - it causes it to "corrupt" the permissions on the SD card - It is still working like a champ and i am waiting impatiently for my EVO Froyo update ... feedback appreciated for those whom tried this fix and had it work....txs

Hi there. So I followed all of your instructions above and downloaded Root Explorer. However, every time I change the permissions, they don't save. User, Group and Other is always switched off at root level. Do you think this may mean my SD card is corrupted?
I rooted it with BakedSnack.
I now want to un-root it as I miss taking shots, looking at my shots, listening to my tunes etc.
But I want to keep all my apps. All my texts and everything else. Whats the best way to go about this? I am also a bit of a n00b and I apologize if this is in the wrong forum, but when Froyo releases tomorrow (apparently) do I have to unroot to receive the update?
Thanks

[Q] Is it the SD card at fault?

hi all,
thought i would ask here as my questions in the rom specific forum are getting swamped by every asking for the dev to install specific programmes or people asking wht OJ death is..
im just trying to narrow down if my SD card is faulty, the rom is causing the issues or i have or am doing things wrong.
on random occasions i have lost apps, photos and other info from my SD card.
the first time it happed i did a nandriod backup prior to a rom update.
right after the nandriod back up my phone booted up and every photo i had taken in the last 2 days were gone.
thankfully using Recuva data recovery program in windoiws i was able to find and restore the photos.
i then updated my rom the Open desire rom, the one that enabled the OTA menu system. as far as i know there were no other things changed in the initial update.
after rebooting all my sd card data was wiped.
BUT.... some of the apps on the sd card were still there and some were gone, as well as apps on the phone, some were gone some was not.

You're not alone... I too have a similar issue, with an un-branded, un-rooted Desire. The first think I noticed was a duplicate "Backgrounds" folder appearing in the 3D Gallery - which in itself is odd, because the standard Gallery app only shows it once.
Weirdly in one version of the folder I have a few less images than the other, but they're otherwise all duplicates and can only be found in one visible "Backgrounds" directory on my SD card. It's not just the Gallery app aither - some others (like Wall Switch) also see two "Backgrounds" folders.
Then I noticed a number of images had mysteriously disappeared from another folder - in both Gallery apps. The only app that's crashed is Wall Switch - which is probably related, as it's looking for images in that "Backgrounds" folder. It works fine most of the time though.
If any images have gone missing, I should be able to get them back as I recently upgraded to a 32GB card and copied all my files across before doing so. However, I'm more concerned that there's a problem with the new card. (Which, for the record, was not a cheap one from eBay.)
As such, I'll be spending some time this weekend testing the new card to see if I can identify any issues... but I too have a couple of questions in that regard:
i) Is there any benefit in formatting the card in the phone before use? (It came pre-formatted so I first checked it for errors in Windows first, then just started using it.) I realise before Froyo the phone could not format such big cards, but I think that may have been resolved now.
ii) What's the best way to verify the integrity of the card? (e.g. Will error checking via Windows - XP in my case - suffice?)
EDIT: I took the card out and copied the files (minus my MP3 library) back to the 4GB card that came with the phone. When I ran with this card the duplicate directory disappeared. CHKDSK found no problems on the 32GB card, but I reformatted it in the phone anyway and then copied everything back to it and all is now fine. I'm assuming the phone did a "Quick Format" rather than a full one, as it only took a few seconds. I'm not too worried about the missing image files as these may have been inadvertently deleted anyway. Fingers crossed the problem is behind me now, but I'll keep an eye on it.

I am having similar issues, it's almost like the SD card is not fully loaded, and tried to load but can't. Things are missing, and then they are there. I am using a new 16GB over the original 8GB.
I am rooted though, am I able to do a format of the SD card?
Also when I choose to make it work as disc drive, nothing happens, does not show up on system.

i had the same issue when i first rooted my phone i was able to put the card in an old HTC and it showed up as a drive in USB mode and i was able to run a file recovery tool to extract the data
then re format and copy the data back to it..
but the current issue is just random and strange...
stuff just seems to disapear as far as the phone is concerned ...
as i have already mentioned i had stuff vanish after running nandroid back up..

So for me it seems it happens shortly after bootup. Yes I give it enough time.
But once I open the all programs area, I see it load all of the icons. Maybe some issue with it not loading untill I open that area up.
Also, most of issues seems to be coming from the App Organizer Application, it's updated often so hopefully my issues will go away.
*As I play around with things it seems almost all my issues are related to the program. Even the issue with it not showing up on my computer when connected through USB. It does show up, just takes awhile, and once it does my Apps Organizer icons flash. So related.

[Q] External SD and Storage Issue

Hi,
I have searched far and wide for weeks trying to find a solution to issues I am having on a Samsung Galaxy S2 T989 (Telus) - unlocked and being used with a Rogers SIM. Android version 2.3.5 | Kernel version 2.6.35.11
I bought a 32 GB memory card (formatted and mounted before using)
When trying to access gallery of photos taken on the phone (I have not added any content from my computer) it gives me the message "not enough memory, delete some items". This also occurs when I try and dl a wallpaper using Zedge.
I have gone through forums that have said to move items over to the "external SD", and when I do that in "Files" it doesn't seem like they are actually being moved over. I have tried to move apps from the phone to the internal SD, and eventually get a message telling me that there is not enough memory on the SD.
I am also unable to connect to Kies (not sure if working on a Mac is part of the issue) and understand this is to be Samsung file manager program. Is there an alternative to this?
I am fairly new to Android, and understand the OS operates quite differently from a computer, but I really feel like I am missing something. And apologize if the answer to my problems is really obvious, but I typically have no issue figuring these things out.
If someone could point me in the right direction, even to a forum or place that explains how it all works, I would really appreciate it. I would like this issue fixed asap, but I would also like to understand why it is happening and am happy to do the research or read about it to learn.
Thank you to anyone who can give me any kind of answers!!!

ODIN back to stock then flash whatever ROM you want to use. My wife's vibrant had the same problem for a while. The only way I could get files on and off was to pop out the sd card and stick it into my computer. After I ODINed back to stock and reflashed CM7 everything worked.

[Q] SDcard issue on every JB ROM

i have a big issue for JB ROM, this quote is have same problem with me:
philsfan said:
Wondering if anyone can help...
on JB, stock google apps and system apps won't recognize my SD Card at all, while outside apps have no problem recognizing it...?
for example, stock Gallery app won't bring up my pictures, mxplayer wont show videos, miui file explorer cannot count/read video files, music, and pictures, however Quick Pic has no problem. Root Explorer has no problem, Titanium Backup has no problem...but trying to access music or custom notifications for gmail/sms won't show up in the system apps (gmail, mms, etc).
another thing is when I plug my phone into my computer, none of my old files are there (but like I said they show up just fine with Root Explorer or any other file explorer).
I've tried every JB Rom available for Toro, yes I've tried SuperWipe, I've done it all.
Any ideas, fellas? Any help would be greatly appreciated. Thanks

#thats some reason why some user not use JB ROM unnofficial
this is 1 of thread disscusion with the same issue http://forum.xda-developers.com/showthread.php?t=1748326

A common reason for media content stored on SD cards not being shown on apps is that the sd card is not being properly scanned, this is supposed to happen everytime the phone starts... but it seems to be a common issue on ICS, even stock roms. I don't remember if JB has same issue.
I used Scan Media, from app market, then after a restart, I could access all my content again.
I've seen ppl recommends Rescan Media as well... you could try those.
It's really weird that you can't access your content when connected through usb to the computer. If you use MTP connection you could try MSC then, see if you can access them.
This is all I can think of, Good luck.

I do!!! I have recently installed this new ROM and I love it! One down of it is the battery life. But I've disabled gogle now services and my battery improved at almost 40% lol It's nice to have it but It's also annoying to charge your phone every four hours. Im retty sure there is a bug continuously running that drains the battery that fast.
NOw going back to the point, the bad problem is that my phone is not recognizing my memory card. Other programs recognize it like file manager and others but every time I go to gallery my phone doesnt recognize the pictures from it. Also the music player doesnt see the music I have on it either. Frustrating :/
I have done so far this:
1. Unmounted and re mounted the memory card using the ROM
2 Unmounted and re mounted the memory card using the ClockworkMod
3. Formatted the memory card many ways and different formats
4. Used a different (blank) memory card with one file
I also read another thread from previous codename ROMs about putting a null file on certain folders? I cant recall it right now, but theres is one thread about it. That did not work as well.
I guess we need to figure out more man. sad cuz I love this ROM

[Q] WMP/Galaxy I747 sync issues

First time post here. my ATT Gal I747 used to sync with WMP 11 nicely but since I rooted my S3, it no longer sync music into my phone. It connects normally showing memory info and connected device in WMP but as soon as I click start sync, it only reaches 21% and is stuck there. Ive tried to copy and paste frm PC to my external storage and says "cannot copy canceling" Im certain its not my PC, I have all the latest samsung drivers installed. Ive tried numerous syncing apps/desktop apps and not one will sync. My question is it a media files usage rights thing, or is it a reformatting the external sd to allow permissions, or is it a usb composite driver missing from my phone that was in stock rom? (btw my stock rom backup took a crap and I dont have it saved.) Ive turned on usb debugger, used different usb ports on PC, other things Im not familiar with in develop options folder, so i will not mess with it. Im currently running slimrom 4.2.2 build 5 with gapps and nova which works great no issues, except for not syncing to PC. Thought about reinstalling WMP but its not a stand alone in win7. Sorry If I typed a whole chapter, just wanted to get all troubleshooting info. I researched online for a solution but couldnt find any. ive looked at reformatting apps for sd cards on line but most of them are for videocams or camera sds on top of not knowing how to format a sd card. TYVM for any suggestions or tips I havent thought of. Much appreciated.
