[FIX] Asus Memopad 7 ME176c. Apps disappearing on reboot - Android Q&A, Help & Troubleshooting

First, root the device using RootZenPhone.
Second, install Link2SD. Run it, and you will see that apps that uninstall on reboot appear as if they were on SD (it's not really that way, read below).
Tell Link2SD to move those apps to internal.
Done.
----------------------------------------------------------
How did I come to this workaround:
I first found that all applications that disappeared on reboot wrote data to /mount/asec, and that the data was wiped out on reboot.
I was trying to move apps to sd with different apps, with no success. But I found that Link2sd gave me the option to move apps to SD. BUT what it really does is not moving them to SD. It moves apps to /mount/asec.
That's where all the applications that disappearead on reboot had data writen to it.
I found, also, that all those apps appeared on Link2SD as if they were on the SD. So I moved all of them to Internal.
And it did the trick! Now applications don't disappear!
-----------------------------------------------------------
I don't fully understand this thing about applications in /mount/asec, and the apparent "confusion" that link2sd has about /mount/asec and external sd, but it worked. And I wonder if anyone with a deeper knowledge about Android could use this observation to also solve the issue about not being able to move apps to sd in this tablet.

[Q] Apps required to be in phone memory.

I have rooted my optimus one.
just wanna know which are d apps that are neCessary to remain in the phone memory.
so that i cn move rest to sd.
Widgets should remain in the phone memory. Everything else that doesn't run frequently should go to the SD card

unable to move maps n youtube.
stil woried abt lockscreen n launchers.
Are you using the stock ROM? Apps that are in /system/app cannot be moved to the SD. If you installed it via downloading/installing from the market or somewhere else, you can move it.
Everything that feels like it should be launched no matter what or those that need to be started quickly on boot, keep it on the phone memory.

Yeah. m on stock.
did move sum apps to sd via app 2 sd enabler.
Cmon guys I thougjt it was safe to move all sh#t to sd
It's safe. It's just that apps that need to be started on boot must be there as soon as it can. Read and write speeds on the SD card is much slower than on the phone memory.
Well he didnt ask for fast boot
It's not about fast booting It's about getting the things you need as fast as you can. For example, I need a widget to load as fast as it can since it has to be there as soon as the phone boots. That was my point
Everything that you don't use everyday move to SDcard (if possible). If you move favourite apps to SD and you acces them all day long you will shorten the SDcard's life.
I have void with a2sd enabled. So all user applications are on sd. Can I use titanium backup to move some apps to internal memory?

I used Titanium to move a lot of stuff over to the SD from Internal... Stuff in the /system directory doesn't affect your phone's "Internal Storage Space" as reported in the Settings menu since /data and /system are separate partitions. Apart from /system apps, the only thing that I would want to move to the SD that it couldn't move was the PayPal App from the app-private location. Going into ADB wouldn't allow me to do it either.
Titanium also allowed me to uninstall a bunch of the **** that came installed like game demos. This did not free up additional storage space, with the exception of what it removed from Dalvik-Cache. Which, btw is going to be your biggest issue... Some ROM's allow you to move this to the /cache partition, but this is a relatively small partition (~56MB) on this phone and my Dalvik-Cache currently takes up ~90MB.
Pls reply here guys.

I use app 2 sd to move everything I dont need frequently on SD, than just long press on those program from app 2 sd and Open them.
It's a bit tricky and I dont know other ways (on the home screen most of SD apps wont appear...) but I never had slow opening and the like

I used Titanium again and used it to incorporate the updated GApps into the ROM. I knew that I had about 56MB free on the system partition. Putting Gmail, Maps, Street view, Market and anything else that I could find freed 30MB on the data partition.

[Q] plz i need an experts help- usb connection to pc or car problem

hey guys i am starting to loose it here
this is the situation, i have a sg2 and its rooted 2.3.6 stock rom.
now i have about 100 installed app, and I bought titanium back up and at one time I moved all user apps to sd card to clear some memory. That caused a big problem for me which manifested in that when I connect my phone to my computer or car stereo that once I unplug the usb cable or disconnect it from my computer the phone turns off and reboots. It drove me crazy I thought maybe its an app thats causing this, in the end i had to move all user apps to internal storage using titanium and the problem faded. I tried it both using USB debugging mode on and off.
So my question is whats the use of titanium or app2sd if it will cause this problem when i move apps, and how can i know which app will cause such a weird rebooting behavior, as I am not comfortable in having all user apps on my internal storage.
ANY help would be really appreciated. And an explanation to why such a behavior happens so that I will learn more about android systems

The explanation is simple. If you connect your phone to PC or whatever via USB and toggle "Mass Storage Mode", you dismount the SD Card from Android OS and mount it for the PC or where you've plugged the phone. This way Android OS can't access anything on the SD card, thus failing to load/run any app there.
To move them to SD, I will use the app options you can find in Settings > Applications > Manage Applications. If the application has the option to move to the SD, then is safe to move it without problems. If the application doesn't have that option and you move it, you could compromise the Android OS stability (depending on the app).
App2SD uses a separate partition on the SD to store the app, that way you can mount the external_sd partition without touching the App2SD partition.
Hope this explanation helped!
do u toggle mass storage ?
could also live wallpapers cause a problem with what I mentioned above.
I usually connect my phone via the following
wireless and network, then usb utilities then press connect to storage PC
So how can I fix my situation now, it all started when I used titanium to move user apps to sd card,
So if I use titantium to move back the apps to internal storage solve the problem completely and then follow you method of moving apps.
Another question is moving apps using titanium doing something different than what app2sd is doing?
App2SD doesn't do the same as Titanium Backup move to SD. App2SD creates a symbolic link so the system thinks the apps are being stored in internal memory but the link redirects them to the SD card.
You could try restoring your moved apps from Titanium Backup and then applying an App2SD script. Remember that to make App2SD work you will need 2 partitions on your SD card.
I am still confused as to How that works, I wish someone would write a detailed guide as many of us r newbie users. So do I have also to Partition my sd if I will move apps to sd using the move to sd option from the phone settings- manage applications.
It's so confusing the difference between moving apps using titanium and app2sd, also how can I partition the sd card.
Also could live wallpapers and widgets cause a USB connection mode instability

[Q] Apps missing using apps2SD

Hi all
I have just installed CyanogenMod 7 on my HTC Desire.
I partitioned my 16GB Class 10 MicroSD card into a 14GB FAT32 partition and a 2GB ext3 partition. I installed DarkTremor's apps2sd scripts, and the apps2sd gui. I set it to save apps to the SD card, and to move the dalvik cache to the SD card.
Everything was working well: I was able to install apps, and they were going to the SD card (had they not, I would have hit the limit of the Desire's internal storage!). Rebooting didn't negatively affect anything - I rebooted several times and the apps were still there.
Then, when I opened the Theme Explorer, the phone just hung. It didn't respond to any input, from the touch screen to pressing or long pressing the power button. Eventually, in desperation, I took the battery out to do a hard reset.
When the phone booted back up, all the apps I had just installed were gone. Their icons remained on the homepage, but with the generic Android icon instead of their actual icon. They were missing from the ADWLauncher panel. The apps are still present in the list of apps, but are missing their icons and proper names. Instead they are displayed with a generic Android icon, and their "long-form" name, for example "com.amazon.kindle".
In addition to all the apps I had installed being missing, certain apps that came with CyanogenMod were also missing, such as: ROM Manager and the program that lists the apps with root permissions (I forget the name). Also, the Market application is missing. However, the calendar, messages, Google Talk, Theme Chooser, etc are all still present and working.
I tried rebooting the phone multiple times, as well as unmounting and remounting the SD card, with no improvement.
Using the terminal emulator, I can see that /sd-ext still has five directories: app, app-private, dalvik-cache, data, lost+found. However, all these directories, including the /sd-ext/app directory, are empty.
Running a2sd reinstall goes through the list of apps, but for each app that is missing, it says that it cannot find the .apk file for that app.
I suppose, then, that I have two questions:
1. Can I restore my apps somehow?
2. If not, and I have to reinstall, how can I prevent this from happening again?
(At the root of both of these is the question "why did this happen?" so if anyone knows that, that would be a great help too!)
Thank you all in advance - please let me know if there's any other information I can provide.
I have a similar problem with my Samsung Galaxy S2 on Sprint. I used Apps2SD by Sam Lu to move many of my apps over to my new 32 gig SD Card. After a bit I realized that I had moved many of the apps over that should have stayed on the main internal storage, mainly because of widgets. So I moved many of them back.
Shortly after doing that I was at a retreat with my phone on airplane mode to preserve battery life. I took some pictures and videos, read my Kindle app and Bible and then plugged it in to charge. The next day several of the pictures and videos I took showed up as a black icon and were not accessible. Then I noticed that all the apps that I had moved to the SD card were "greyed out" and even some of the apps that I had moved back to the internal storage. The phone then told me the SD card needed to be formatted.
Since then I have tried to use file recovery software to recover missing files on the SD card and it finds hundreds of photos and several videos, but nothing else. So the big question is, where are my apps? I hope you find a solution to your issue because it may be the same solution for my issue.
Sincerely,
Nathan

[Q] Solution for apps disappearing after reboot with S2E?

I've been searching and reading various answers on the subject on different phones, but I wanted to know what worked best for Aria owners.
I've done the following:
1. using Cyanogen 7.1.0 factory reset the phone.
2. formatted the SD card to have a fat partition, ext partition and swap partition.
3. installed s2e and moved the checked the apps, private apps and dalvik cache to sd.
4. checked the 'Internal' on the storage location in the application settings.
5. Installed apps everything worked fine for a couple of days.
I've rebooted the phone today and all the apps I've installed on the SD card are gone, they don't appear in the drawer. Also all of their icons are switched to generic android icons.
I've read on different forums it's got to do with the launched running before the SD card is mounted on boot. some recommend moving back the apps to the SD, but I can't do that since I've got no access to S2E, and I have to use the SD card anyway since phone memory is so small. Also many of the threads were old so I've thought something may have been changed on new Android versions.
Is there any way to solve this? I don't have access to the market so I can't install anything from it.
I'd suggest moving only application and dalvik cache (not private apps) to see if it makes a difference.
Is your partition formatted as ext3 or ext4? Are you using the "mount as ext4" option in S2E?
partition formatted as ext3 and I've used mount as ext4.
is it preferable to format it to ext4?
how can private apps can cause a problem here?
I've now wiped the phone, re installed Cyanogen and Google apps.

I don't think it's the cause, but I'm just trying to eliminate anything that is different from the way I've set it up on my phone since I don't have that problem.
Personally I use an ext3 partition without the "mount as ext4" setting enabled. Perhaps that setting is causing your problems.
did you install the rom, apps and the s2e, or you install the rom, s2e and then started installing apps?
are you using the default adwlauncher or did you switched to a different launcher?
When I do a clean install I install apps before and after enabling S2E. It doesn't make a difference.
I've used several different launchers (including ADW EX) but not the built-in one.
do you enable in settings - Cyanogenmod settings - applications the following:
allow application moving - checked
install location - I select internal instead of automatic.
"Allow application moving" unchecked. That setting only makes it possible to move any application to the FAT32 partition, which you shouldn't be using at all.
Are you manually moving applications to SD card in application settings or something?
Maybe that's were the problem is. and you have the setting of install location on "Automatic" or on "Internal" ?
Please read this post where I explain the proper way to set up S2E when using it to move applications: http://forum.xda-developers.com/showpost.php?p=21667779&postcount=5
When you are selecting "move to SD" from the applications settings, you are moving the application to the FAT32 partition, which is NOT what you want. On its own, this wouldn't cause any applications to stop working though. However, since you enabled the "Allow application moving" setting, that forces the phone to allow you to move any app to the FAT32 partition, even if that app does not support it. When you move apps to the FAT32 partition that don't support it, those apps will stop working.
thx for the explanation.
If I'm setting up the s2e before installing any app, I can skip step no 4 as I understand it.
is there a real difference in performance/compatibility to the file system on the ext partition? I see threads here that mention that ext4 work without any problem.
should I format the card to ext2/ext3 or ext4 ?

ext4 should work fine. I only suggested moving to ext3 because you were having problems, but it sounds like that was unrelated.
Ok. I've formatted the card with gparted, wiped the phone, but no matter what I did S2E didn't show the Ext partition. I've finally used rom manager to partition the card and it worked fine.
I've checked the setting as you've recommended, and so far it seems fine. I'll have to wait and see if it doesn't shows up again after several more reboots.

same with me after installing battery script that wipe the Dalvik Cache
i thought that was the problem
i did reinstall everything and still waiting to see
read the entire thread, my problem was completely solved.
I am having this issue also - I goofed and checked the 'mount as ext4' for an ext3 partition. Now I can't see any apps, including the S2E app to uncheck it or the Play store app to download another copy so I can fix it.
Any suggestions how to correct? I can't even boot into recovery mode to reflash at the moment...

Boot to recovery with SD card removed, and/or reformat the ext partition of the SD card from a computer.
Fast Boot option may be the culprit
I see folks here are deep into ext3/ext4 partitions and such (or at least you were a few months ago), and I hope it all works out great for you.
Just in case, here is a simple little fix that really helped me, without resorting to all the partitioning and reinstallation going on here.
Also, for what it's worth, I used ROM Manager Pro to auto-format the special "ext" partition on my sdcard when it was pristine, and since then have used Titanium Backup Pro to move apps to SD AFTER installing via Google Play Store or very occasionally side-installing .apk files.
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!

[Q] Some apps not working after using Link2sd

I use link2sd to link app, dalvik (dex), lib and data files of all 3rd party apps that I install to my SD card to keep the internal memory clean and save space. Most of the apps work but some apps like Subway Surfers, Rail Rush, etc. stop working after linking everything and REBOOTING the phone. Until I reboot, it works but not after that. When I try to launch them, I get "[app] has stopped working error". 95% of the linked apps work totally fine. Problem is only with some apps (these apps that are troublesome are mostly the ones that automatically get installed to the SD card. But even if they do, only apk is stored on SD card and the dex, lib, data are still on the internal memory so I still need to use Link2SD).
Any solutions? Or workarounds?

Install these minority of apps as the developer intended? , if it's only a few apps it's hardly going to swamp your internal memory.

Yeah its just a few but I'm afraid I wanna keep more such apps in future which might behave this way. As far as it seems, this problem is only with some of those apps which automatically get installed to the SD card (like subway surfers). I found a workaround that seems to be working. Firstly the app needs to be moved to the internal memory before linking (which I already did before). But there are two ways to do this: One through the Android system (Settings -> Apps -> SD card -> Select app -> Move to phone) and other by using the Link2SD app (Select app -> Move to phone). The second option solves the problem. If the app is moved to phone using Android system, then linked to SD card and rebooted, apps stop working. So, its needed to move it to phone using link2sd.
