As title says, I have a problem copying high resolution images (say 2569x1600) into my phone. While copying files from PC phone turns off or screen goes black and touch sensitive buttons at the bottom blinks.
I thought it is problem with my sd card, so I reformatted it but still couldn't resolve it. To get over this problem I even tried reflashing, still no luck. I think it shouldn't be a problem copying HighRes images as phone itself captures images at the resolution of 3264x2448!
Anyone else with similar issue? Please help!
How are you copping the files (usb, wifi)?

I tried both way but same problem occurs.
Have you had this kind of problem?
Sometimes i have similar issues. The problem is faulty sdcard (or at least faulty in the phone).
I proved the sdcard + phone combination as faulty this way:
1. Boot in openrecovery and issue adb shell to the phone
2. Simulate some sdcard activity (i was using dd to read and write to a file over the sdcard)
Look for "dma" errors in the dmesg output. if that happens usually you can do something with the phone, but nothing which access somehow the card
Alternatively:
From normal mode, connect via adb to the phone. Copy the files, phone will "freeze", but the linux in it will be alive again you can see dma errors in the dmesg output Your shell will be alive (even if it will be necessary to issue another adb shell command), but the phone framework will be freezed
If somebody is curious the sdcards, which make the phone freeze are realy faulty, but not so obviously. e.g. you can use them normal with other devices and pc. But if you go deep and run some test (divide card in logical parts, then compare the read speed of this parts) you will see that the card is gone to gone...
Anyway, i think that even problematic sdcard dosen't have to make the phone freeze. but .... moto decision (or moto fail)

I have had this problem, although it wasn't when it was connected to PC. I will get it sometimes when I an downloading off the internet directly to the phone.
What happens with me is the download gets interupted for some reason and then when I try to reset it back to Home screen it never goes. I soft touch the power button and then that is when I see only the 4 lights at the bottom light up and black screen.
I have to do a battery pull and then when I am fully booted up is when I can fix the issue. Something in the interuption causes the SD card to unmount and you get a corrupted file on there. Let's say I was downloading a picture and this happened. Once I do battery pull and reboot, if I go into the media.apk and see my pix, there will be one that is grey and has a ! in it and also I'll get a notificiation that could not read/write to SD card. Find that file, Delete it, go into settings and unmount SD card and then remount it. You will lose whatever pix it was but my SD card is now mounted again.
Sorry for the long description but it has happended to me a number of times and I even started a thread about it. Moral of the story os that a connectiong was broken during download. Either USB came slightly unplugged or BT signal was interupted, or (this happende to me once) the screen timed out and if you have JuiceDefender it will cut your connection.
Find the corrupted file and deleted it, un-remount SD card (in phone) and maybe try transfering smaller batches over at a time.

Thanks mate. Now I guess, I have to resize images to lower resolutions to get rid of this problem. Again thank you for the help!

I have exactly same problem as you described. I did battery pull, deleted all the corrupted files and then copied them again but as you said connection gets disconnected and black screen appears. Is this problem with MIUI too, because that's the last option I have left with.

I wouldn't say it was anything with the ROM you are on, but main the quantity of material you are transfering at one time. Maybe try to cut it down and do small batches and see if that works.
Btw, I am on Kahl's v4 Epicsteelblue ROM.
Are you overclocked? Perhaps your vsel is too low.
If you're using WiFi make sure to set the WiFi sleep policy (or set your screen not to turn off)
Settings >> Wirless & Networks >> WiFi settings >> (menu) >> Advanced >> WiFi sleep policy >> Never off
it is just the sdcard.
before proving within openrecovery, have tried stock clocks and vsel (e.g. not loading overclock.ko)
also was in doubt about vsel, so tried in openrecovery at 250MHz (suppose the vsel was the standard 39 or 32 don't remember exactly).
So it is not the vsel (or at least vsel alone, may be combination of vsel and frequency )

Previously I used to run MilestoneOverclock @1Ghz with 65Vsel. Last night I tried reflashing , phone wasn't rooted, no overclock module, no Setcpu - phone was completely at stock values and still same thing happened.

That could be the solution but when plugged with USB cable, phone behaves in same weird manner.
Because that happen only when you copy image, so i think your gallery (or another image software contain error when it make the thumb of image). Have you tried remove gallery and copy to see what happen?

No, I didn't try that. After reflashing to stock there shouldn't be any problem, right? It still happens. Really annoying problem. So what I do now is resize images to 854x480.

You could try creating a folder with a file named .nomedia inside it (that will prevent media scanning) and see if you can transfer the image into that folder.

Make sure you google .nomedia and read about it before you do that. There are some bugs and issues that "can" come along with that. If it works great, but if not
It worked for me on a few folders but I didn't push my luck with it.

Funny thing is happening on my xt. If i put 16gb class 6 sd card, and when I am on phone call I get random scrambled noise. Until yesterday I thought that it is some kind of hardware failure, but after replacing sd card with provided one with xt (8gb/class 2) everything is working fine...
Sd card is sandisk....

Ive had a weird problem the last day or so, when I reboot my device, apps mysteriously go missing. Each time I reboot, like 5 or 6 different apps disappear. This only happens to SD card apps though. This started happening a few days ago but yesterday it got alot worse AFTER I had reformatted my card. Could there be something wrong with my SD card? The apps still appear to be installed in "manage applications" but they look like "com.aac.cachemate.demo" as the name of the app, instead of "Cachemate" and etc...?
did you use link2sd ?
com....whatever in manage applications usually means, that the apk file is missing, while the application data is present
the mess as described, can be seen if your ext partition is mounted too late ...
nadlabak has some fix about it
https://github.com/nadlabak/android...mmit/e5b9b3195687e04af7a7929f8637e77e1efae9a1
but i can't remember where is part of setting the property, after checking and mounting the whole card ...
nikctsh said:

Click to expand...

I did not, I used the standard apps2sd built into CM6. Every time I reboot, different apps are missing and then some come back that were missing the time before...They all still appear in manage applications though so they might be intact but I'm not sure if all are, they show up with the default generic android icon, and weird names. "mobi.mgeek.tunnybrowser." (Dolphin Browser) and "net.flixter.android" (Flixter) etc...The storage sizes of the missing apps appear to be different then they are supposed to be. (Maybe)
(This might have something to do with it) Yesterday for hours (before I reformatted) the phone was stuck at "Preparing SD card, checking for errors" so I went online and followed the suggestion an xda member who suggested in another thread to delete the "fsck_msdos" file from "system /bin" which disables the SD card check to see if the SD card has been properly mounted and checked. It seemed to fix my other SD card issue for the rest of the day. could this be related?
Just share my experience , when I was in 2.1 , I used link2sd , and if I boot without sdcard , all my linked apps will happen like that , I think maybe this is the same case as apps2sd . So , what I do is just uninstalled all those apps , and reinstalled some of it ( it's quite annoying to reinstall over 100 apps ) . As you said , all those apps remained as it's package name , so I'm kinda sure our case is almost the same . But when I was in 2.2 , once I booted with sdcard inserted , but after boot completed , all my user apps dissapear , yes , ALL . But anyway , after scan for sdcard problem in OR , all my apps recovered , with no force close , just like nothing happen during the last boot . So also , try to scan for sdcard problem in OR .
It says my card is mounted (about half of my sd card apps show up) but when I bring up the gallery, it says "SD card unmounted or not present." When I try to unmount it in settings, it never unmounts, I just click "unmount" and nothing happens....

It sounds like you have corruption in your sdcard filesystem. I would take your sdcard out, put it directly into a Windows PC and run chkdsk (alternately fsck.msdos on a linux PC).

Ok I will run a chkdsk when I get some time to sit down at the computer later. I think it probably is corruption.

SD card fixed with error checking in windows!! Thanks!
Fast Boot option may be the culprit
The advice about checking SD card on Windows or Linux sounds good and I will keep it in mind, but I did not need to fix this sort of problem. I am not familiar with CyanogenMod (CM) in any version, but if it has a fast boot option, read on...
CUT TO THE SOLUTION BELOW -- SEARCH FOR ////
Some (not all) of my apps moved to SD (all by Titanium Backup Pro) have begun to disappear and (sometimes) reappear without warning after I began to add and delete large Virtual Machines created in QEMU from my 16GB SanDisc class 10 microSD card on my HTC Droid Incredible running rooted stock Verizon Android Froyo 2.2.3. I know this thread is far from my phone's "home base", but from what I can tell this problem with disappearing apps located on an sdcard is NOT determined by hardware or even Android version.
I also happen to use LauncherPro by Federico Carnales instead of the built-in HTC Sense launcher. I noted elsewhere on XDA that a user had suggested that because at least some (maybe all) launchers start before the SD Card that this may be a problem, especially if changes are made to the sdcard that the launcher did not perform, or was not active during their performance by other apps such as Titanium Backup. That fits my situation, because I unmounted the SD, physically removed it to a PC, and added/deleted large VM files to save (lots) of time. No problems of this sort before I did this, so there must be some connection.
I noted that other users have tried reformatting SD, substituting different brands of SD, using newer/older SD etc. None of these reliably helped. So I skipped these options.
//// The (simple!) solution I tried that SEEMS to work (only time will tell!) is buried in the main Android Settings (accessed from the Menu button while in Home screen). Under "Applications" there is a setting "Fast Boot" that I checked long ago and forgot about (it seemed like a good thing to do at the time). The text warns "Turn off to use some Market apps" (that shows the age of my 2-yr old used phone and Android OS -- ohmygosh!-- because it refers to Market rather than Google Play Store!) Anyway, I unchecked the option and rebooted the phone.
Yes, it took a bit longer to boot (maybe a whole minute!), but after waiting about another minute ALL my home screen apps had normal icons and loaded properly. Titanium Backup Pro batch scenarios confirmed there were no apps in a forced uninstalled state (i.e. I had not done the deed, the system somehow had done it or at least rendered the apps "invisible" to Titanium, which decided they needed reinstallation).
The only odd behaviour was that auto brightness was turned off after I unchecked Fast Boot and rebooted. Going into Android Settings > Display and rechecking "auto brightness" took care of that. No other oddities or strange behaviours thus far (but it has only been about an hour).
I will report back here on this thread only (Samsung Fascinate > Fascinate Q&A > What just happend? apps on sdcard) if anything else requires reporting. Silence implies success!

(I am copying this post to other relevant threads, but will not post anything further elsewhere -- only there. This is a bit arbitrary (although this thread appears to be the most recent active one on this topic), but I hope this approach pleases the XDA sysops/admins) :angel:
Sorry for opening up old thread. My HDC Note3 clone phone having the same/similar issue. The phone have 8G ROM which partition into 2 different name, internal phone (1G) and SD card (5G). Whatever Apps that I install on the SD card will disappear from home menu every-time I re-boot using the power button. However, it it still there when the phone do their own reboot due to something
I try unchecked "Fast Boot" but disappearing act still happen. Any suggestion to resolve the issue?
Hi,
Did a search but could not find anything like this.
Problem with my new Gemei G9T Android 4 Tablet. Until 3 nights ago it functioned normally, but 2 days ago I switched on and there was a problem accessing storage. File Browser and ES File Explorer cannot access internal SD, nor can QuickPic, MoviePlayer, or Music. Icon continuously shows ‘preparing SD card’. Settings accesses most functions, except ‘storage’ and ‘developer options’ which cause it to freeze. Tried factory reset – did not work. Most apps work fine, but not Camera or Gallery. Cannot access external SD or USB storage, or connect to laptop. Entering sleep mode causes power off. Normal powering on and off now require two presses with time gap between. All of these functions were fine previously. Have you any suggestions, please?

Try to take out your SD card and put it in a Card reader, remember to do it while your device is off or unmount it from memory settings, try to swtich on your device later and connect it to your computer and check if it connect through USB or not.
Try some system tools?

I'm guessing databaiz's suggestion to take out the card isn't an option because it's the internal sd card, right? If so, for the one-in-a-million chance that the external card is screwing with the bus, I'd take the external card out and reboot anyway, just to make sure; if it works OK then, I would check the external card as databaiz suggests. But assuming it still doesn't work, next question is, do you have a terminal app installed? Please try the 'mount' command and let us know what you see. One other question, will it still go into fastboot mode? Can you see it from your computer when in fastboot mode (the details of how to do this depend on whether you have windows or linux/macOS - I can maybe help with the latter, but not the former).
It could be bad card
It could be bad card.... Remove and test in card reader...
cannot access internal or external storage
Thanks guys, I have been booting without external memory, with problems still the same. So, cannot be problem with external SD.
The internal SD card is not accessed properly. When I go to settings>Apps>All, the line at bottom shows Internal storage 4.1 MB used, 798MB free. (I have uninstalled most apps to see if that helped – it did not.) So, something is accessing the internal SD, also apps are running which must be off the internal SD.
I do not know what a terminal app is, Urilabob. I have downloaded it but what do I do with it?
At: [email protected]:/ $ I keyed in # mount [enter] , making:
[email protected]:/ $ # mount [enter]
But nothing happened, just another line of: [email protected]:/ $
Also, what is fast boot mode – this is not the same as sleep mode? This is all new to me. Appreciate your help.
My laptop is Windows 7.

Sorry, I replied earlier but it seems I messed up so the reply didn't appear.
My problem is I know unix fairly well, and android is very similar, so I forget what is the same and what's different. Sorry, the command you need in the terminal is "df". That will show you a list of what partitions are mounted on your system. I'm guessing you're going to see /system, but not /mnt/sdcard. Why, I don't know. It's possible that the sdcard partition has got corrupted - but suspicious that the external card is also having problems. Is it possible that either the tablet or your pc crashed while you were copying files between them? Or that you disconnected the cable between them before telling the tablet to go out of connected mode? Either of those could explain corrupted partitions. Unfortunately fixing them may not be easy.
There are three different ways to connect your tablet to a computer. One is so it looks like external disks. I got the impression you already discovered this, and that it has now stopped working. The other two require you to install (parts of) the android development system on your computer. The simplest one is adb mode. Please google it to see how to use it. This might give you a chance to check the state of your partitions. The other is in fastboot mode. Fastboot mode is an alternative way of starting your computer, that goes into a fairly bulletproof, but very simple, mode that allows you to do various things on your tablet (it gives you very low level access to the tablet - powerful but dangerous). I'm pretty sure it will still be working. How you get into fastboot mode depends on your tablet; you'll need to google it. And how you access it in fastboot mode is fairly different on windows. So I'm not the best adviser. But please be careful - it's easy to brick the tablet in fastboot mode, you need to make sure you completely understand any steps you might take, especially any that might write to the tablet (of course, reading from it is safe). And of course the simplest alternative is simply to completely reinstall the tablet (sorry, I forget the android term for this). That should restore things OK, but it will mean you lose all your data and will have to reinstall all your applications.

Thanks, Urilabob. The command df had an effect!
Shows Filesystem with figures for Size, Used, Free, and Blksize (4096), next to each of the following:
/dev, /mnt/asec, /mnt/obb, /system, /data, and /cache. The figures are all different except Blksize.
/mnt/sdcard is not shown.
Does this tell you anything useful?
I have never been able to access the tablet from my laptop with Windows 7. My son’s laptop has an earlier Windows, so I checked today and found that his Windows Explorer finds the tablet (as 2 disks, A and F) and asks “Please insert a disk into Removable Disk H:” (and same for F.
By the way, this problem started when I downloaded the (automatic) firmware update direct to the tablet, not via laptop. But the wifi signal was weak, and files may have been corrupted. I have since downloaded the complete, latest firmware to the laptop (with strong wifi signal), but do not know how to get it into the tablet!
Have not yet done anything on adb or fastboot modes. Will Google adb tonight.
Not worried about losing data or apps.
Thanks again, Brian.
I'm guessing that your tablet is rooted? If so, do you have an app like superuser? I remember having to go through some options to give my file explorers access to my SD card. You may have accidentally set you SD card to be off-limits or something. If you haven't already done it, see if giving an app like ES File Explorer superuser access will help.
Also see if you can enable USB debugging. For my nook color, I have to enable in order to access usb mass storage for one of my memory units. See if you can access your internal SD card content through USB debugging.

Thanks for your thoughts. My tablet is not rooted. And I cannot enable USB debugging, because Settings freezes when I tap Developer Options to get to USB debug. I am just learning about Android - seems to be 2 partitions on the internal storage, one about 2.6GB with apps and other things on (which is accessible), and the other partition must be about 13GB, but has not been accessible since the automatic firmware update.
Sounds like the update caused you issues. If you have everything backed up with your Google account I recommend that you do a factory data reset and see if that fixes your issue.

Factory reset would be great, if it worked, but it does not function.
Can you exchange the device?

OK, so from your df listing, it's clear that sdcard is not getting mounted. That's a pretty low-level function that is failing. The fact that factory reset also doesn't work suggests (doesn't prove) that the sdcard partition at least has a corrupted filesystem, and quite possibly the partition itself has been corrupted. Could a spotty OTA update do that? I'm surprised - I would have thought they would use fairly high level functions for OTA updates, precisely because any drop-out could cause corruption if you use low-level disk access. But who knows - the mysteries of google? Another possibility is that the sdcard is physically bad, and maybe the update just caused you to get into the bad region (with the dynamic memory mapping in flash memory, once something goes wrong it's almost impossible to figure out what). At this point, I'd be going back to the distributor if possible (you said it was new, right)? I think even if you were an android guru, and knew exactly how to do a complete rebuild from scratch, you would be risking that the device itself is faulty - and that the rebuild would mean you couldn't prove that the device was at fault (rather than your rebuild)...

Thanks, Bob for all your help. This seems like the end of the line with this tablet. I expected this might be the case, and emailed DinoDirect two days ago for a refund, as I am heading overseas next week and want to resolve the matter before I go. They responded that "we will contact our related department to process your case priority". I have been aware that any actions I might take could invalidate the warranty, and this has inhibited me a bit. I will forward your latest comments in support of my refund claim.
I learned some basics of Android from all this!
Good wishes, great talking to you.

Just for a great justice :victory:
Got same bug on my Gemei G6, guess it hapens after i connect dc cabel to a fully charged pad that was charged in off mode and turn on. So i just download last firmware fro Gemeitech.com, unzip it on SD card and tnen turn on pad with pressed Home and Power buttons that must be pressed untill robot with green rotating belly appears what mean start of flashin` Thats it.
Got the same issue in Huawei Ascend P-7, I just switched off the mobile, removed the SD card and turned it back on after 5 minutes ....... and that was it, all issues resolved. Just the thing was that once SD card was re-inserted, problem came up again. So i have decided to copy SD card data to PC via Card Reader and format it or get new SD card
So in preparation for backing up my internal storage for 4.2.1 in case it messes up or I do I was planning on copying everything from my internal device storage onto my computer. When going through the folders to see which ones were empty and I didn't need to copy I came across a folder that I had deleted the contents of earlier that day. Thinking I may have not actually deleted it I did it again.
Before copying the information over I went to check to make sure I had my backup of my nova launcher and noticed it wasn't there, I went to make another backup when I hit restore just to check that there was a back up and there was, and in the folder I had just looked on in my computer.
It was then I realized that the data my computer showed was very old files, things I had deleted months ago and some of the newer files were not being shown. I also noticed that old videos and pictures showed in my gallery app even though I knew I deleted them. I tried rebooting my tablet disconnecting it from my computer and reconnecting it and to no avail I also cleared the gallery app data and that seemed to fix the phantom videos and pictures in the app.
If anyone knows what is going on and how I can correct this issue that would be helpful as it does not seem to be an issue with my phone, Galaxy S3.
Thanks,

You are using MTP connection to delete files/folder or just a file manager? I had similar issues when i was using my PC to delete stuff from the internal storage so you could try to use a file manager and see if it solves the issue.
I do delete stuff from es file manager, I rarely connect my tablet to my computer but when I do its using MTP and only to put files onto the internal storage or sd card.
The gallery thing happens to more people, we have a thread about a multi-GB cache file somewhere around here.
I have never had it show old files on my pc though. Have you tried rebooting your computer? (I feel a bit like the microsoft helpdesk for saying that... xD) Oh, and a registry cleaner might fix the issue. (for the pc, not the tab.)
I have had my sgs3 not showing up at all every once in a while (i use mtp a lot), but thats probably me being an idiot and killing the media storage process again. (I clear out all non-essential processes when gaming.).

I haven't tried rebooting my computer after plugging my tablet it, but I normally turn it off every night and as I said before I rarely plug my tablet it so I don't think it's a cache issues. I'll clean out my registry and maybe I'll uninstall the drivers for my tablet and let them reinstall too.
I was able to fix the issues by switching usb ports I plugged it into, it started showing the proper files when I plugged it into the first usb too. I took a picture while still connected to the first usb port and it showed up in internal storage in my computer so I don't think it's a usb problem.
Thanks for the info on the gallery issue, maybe this cache file and issues I'm having are connected some how.
Using HP Laptop and have WD external drive which is working fine till last night. Today, morning when I connect my external drive into my system it is normally appearing in my system but showing no data in it. Could anyone please tell me what I can be the possible reason behind this issue and how I can resolve it.
Hi,
There can be many possible reasons behind disappeared files from the external hard drive, file might be hidden, any viruses made them invisible or might be file deleted due to some unknown issue.
The first solution i would suggest you to try is "Enable Show Hidden File" Option available on header of Windows explorer. Just check the show hidden file option to see if the files starts appearing again. If this won't help you out then i would suggest you to go for any data recovery software to get your lost files back.
I am also stuck in the same situation a few days past. But after a lot of research and reading multiple blogs I found this SysTools Hard Drive Recovery Tool. I really the tool just save my data life as well as my data too. It is quite a nice single interface tool, that really works and is capable to recover files from external hard drives.
