App Installation from SD Card. - RAZR i Q&A, Help & Troubleshooting

I wonder if someone could tell me, please, if it would be theoretically possible for someone to remove the micro SD card from a locked Android device and use this to install/run a hidden app on the device when the card is reinserted?
Is it possible to find out if the device has any hidden apps running?
Thanks.

When notting extra has been done to the phone it won't.
The only way to get it working is by installing a secondary app/service that is installed on the phone with su rights that calls the sdcard and installs the app or starts the app when a sdcard is found.

Titanium backup error at start up

Im trying to use titanium to wipe youtubes data to get youtube working (/data shows as being empty in astro), but it says that my busybox is working but su is not elevating proporly. It says that when it ran a whoisit the result came back as applet not found and that it thinks my SU whitelist system app isn't working and to check with my rom provider. I rooted using autonooter, how can i fix this error?

I'm getting the same exact error. I'm really interested to see what the solution to this is. I haven't had any problems and it seems to be fully rooted. This is the only error I've seen anywhere.
Use the "Problems ?" button at the bottom of the screen when Titanium Backup is running. It will download and install its own version of Busybox.
Also, make sure you have an SD Card in _before_ you start Titanium... that was the only way I could get it to see apps.
I don't have an sd card in. The problems button doesn't help because busybox isn't the problem (i tried it). I will put on am sd card and try again. Just going to reformat the one i used for autonooter

Preventing apps from installing to sdcard possible?

I want to start fresh and wipe my sdcard that was in the revo I had. I can just do a standard format on the computer for it right and it work fine in the phone?
Also, is there a way to prevent apps from installing on the actual phone? I want all my things on the sdcard instead of on the actual phone.
not that i know of there is a app to sd to card app and i think there are options in the manage app menu and i think there is a force to sd app that requires root if i am not mistaking..
If your going to do that, why not just use the card that came with the bionic?

[Q] Order of operations: when to move apps to SD card & when to swap SD?

To no avail I have sought a definitive order of operations for the housekeeping tasks to perform post ROM install. Specifically, at what point should one move apps to the external micro SD card and at what point should one get into the Buildpropeditor to change the SD0 to SD1 for the swap SD procedure?
Here is my usual order of operations on the bunch of ROM installs that I have done.
I make a nandroid of my current ROM (using TWRP).
I make a Titanium backup of all my apps and data, saved to my microSD card.
I make a Titanium backup update.zip (I am still not totally sure what the heck this is but I do it each time and then restore it for good measure -- somebody educate me).
Since I use LauncherPro, I make a backup of my LauncherPro settings, also to my microSD card.
I install the new ROM and GAPPs and update.zip to my microSD card.
I reboot to recovery using TWRP.
I wipe cache, dalvik, factory reset and system wipe. I do those wipes a couple more times for good measure.
I boot into recovery.
I flash the ROM.
I flash the GAPPS
I flash the update.zip
I go to ADVANCED
I fix permissions
I reboot.
I lot into my Google account.
Google starts downloading all my apps.
When that is done, I restore my Titanium backups. I restore missing apps and data and system apps and data, and all the restorable things listed under the restore category.
I reboot.
Now, at this point, what comes next? Do I move all my apps to the microSD card and then go into buildprop and swap the SD?
What is the order of operations for the whole ROM flashing process? Are the steps I showed correct? And how about the very end? When to move the apps to the microSD card and when to swap the SD card in buildprop?
Once first boot is done and after google restores my apps, then before I open or setup any apps i edit build.prop 0 to 1,reboot then set all my settings

Swapping 0 to 1 makes my apps disappear

Hmm. I just found out that if I flash the new rom and GAPPS, move all the apps to the microsd card, and then do the buildprop change from 0 to 1, all my apps disappear.
So is it conclusively true that one must make the buildprop change from 0 to 1 before moving each app to the external microsd card?
I don't move apps

Why don't you move apps to your microSD card? The popular wisdom seems to be that you want to keep the very limited internal memory as free as possible. Is that a misconception? I have always been curious about this.
I don't move them simply because I have never needed to, once the 18 apps I use are installed and build.prop is edited and rebooted the folders appear on my sd card, so I'm guessing that the app data is stored on the SD card, i have never came close to running out of space, i average 500mb + free on internal storage

Hey guys I have a secret, after first boot and you log in, shut of the phone back to recovery and flash the update.zip it put all your apps and data back on the phone. Eliminating the need to go back into titanium, and you can go to gplay and stop it from falsely trying to download apps

Is it necessary to boot back into recovery after flashing and first boot and log-in? Is it possible in TWRP to set up three consecutive flashes, first the rom flash then the gapps flash then the update.zip flash? Or is it necessary to flash the rom and gaps, reboot and log in and then reboot to recovery to flash the update.zip?
Yes you have to reboot, if. Not it gives a failed and tells you to boot ROM first. And if you have an update zip you are happy with, then twrp really is only needed to keep up with updates and such for your update zip.

Can't save photos to sd!

I recently rooted my phone using the Chinese vroot tool and then installed SuperSU to remove the Chinese su. After that I installed busybox, pimp my rom, system cleaner and no bloat free to remove all the crap Samsung put on this phone. Now think I might have gone a bit overboard with my cleaning... The problem I have is that i can take a few photos, then close the app, re-open the photo app and then if I try to take a photo it won't save it to the sd card until I unmount and remount the sd card. Any ideas what could be causing this?
Thanks for your help

The problem is more complicated than i thought. The phone recognizes the extrenal SD but only in read-only mode. I can only briefly write to it before it gets back at read-only mode
I reflashed the stock firmware with Odin but the problem is still there.
It goes so far that if I connect the phone to my PC with USB the external SD Card is found but it doesn't show any folders or files when I select it.
And after a little further investigation I found that I can take pictures as normal (save to external SD) untill i open the file explorer, then the external SD card only gets read-only!! Frustrating!
Update: looks like the sd card itself is the problem. I put in a different one and everything seems normal.
I'll try to do a chkdsk on the old one.
It was a corrupted file system. Fixed it and everything is back to normal.

External SD Card.. issues deleting files.

So I have a bunch of movie files and tv show files on my external sd card. I have it in my s5 watch from it. When I am done with them and try to delete the file.. it tells me that it cannot delete files due to some security changes in kitkat.
any way to get around this?

Where are the files from? Did you download them from a PC and transfer to SD or get them through an android app like Google Play Movies? I have read that kit Kat has new security features meaning apps don't have complete access to the SD card. It is possible the card thinks a malicious app is attempting to remove files even though you are telling it to delete them and rejecting the command, for security reasons. I am unaware of this issue since I have not seen it happen on my phone. Try to plug your phone into a computer USB and delete through the PC operating system instead of directly through the phone.

The stock My Files app can erase from the external sd. If you're rooted there is an sdfix app which will enable all apps to access the external.

It's preloaded on the phone.

If phone is rooted, install app like root explorer and delete.
If phone is not rooted, try deleting them using stock Gallery app or Files app.
Kitkat, by default, imposes restrictions on 3rd party apps from deleting data on SD card.
