Database Develop

In and Out

While I wait to find someone who knows the answer to my other question.
forum.xda-developers.com/showthread.php?t=764260
I thought I would ask another re: the memory. I have an 8Gb with a class 6 16Gb external. When I install apps they always put their data on the internal 8Gb. Is there any way to change this and if not what would happen if I just cut and pasted it all there?

if you cut and pasted the data from /sdcard im pretty sure your apps would run fine and re-create the data as its needed, as most of this data ie for games, is savegame data and resources.
After coding an audio recorder myself im pretty sure the location where this data is stored will be coded into most apps, well thats what i did, and most if not all apps unless they allow you to change the string variable as an option, will use the internal SD because some people might not use an external. So imo it depends on the app
Also if you have rooted your device and have root explorer you will see that infact, most of the applications data from installation is not on the sdcard at all

Strange file system issues

My file system is totally confused. When I browse to EMMC from a file manager it goes to my SD Card. If I browse to SD Card it actually goes to the internal drive.
I've had my rooted Nook Color for about 5 weeks now (CM7 booted from a SD card). Everything was working great until I tried installing some different launchers. I tried GoLauncher, Zeam, ICS, Honeycomb and maybe one more. The default was ADW. Maybe I confused the system by constantly switching from one to the next but at some point the system crashed and I rebooted.
Once rebooted I noticed that many of the games I installed told me I needed to redownload their data files. I looked on my card, through my Mac, but the original files were still there. Turns out the Nook now installs apps on the internal drive rather than the card as it had been before.
Wouldn't be so bad but, as mentioned earlier, the file system is confused. When i need to manage files I've loaded on my SD card I have to browse to EMMC and vice versa. Makes my head spin.
Is there a way to fix it without starting from scratch? I'm using CM7.2.0.
Thanks for your help

That's not a bug, it's a feature. Anyway, what you likely did is Settings -> Cyanogenmod Settings -> Application Settings -> Use internal storage (checked). If you do this, then it swaps the mount points for the SD and the internal memory, so the SD card is mounted at "/emmc" and the internal memory is mounted at "/sdcard". See the first post in the thread in my sig for more information about this.
If you really want to return it to the original way, wasting 5G of internal storage space, then you can uncheck that box in the settings and it'll go back to normal.

Thanks for pointing that out and glad to see there's an easy fix. Seems a bit confusing though, like it's renaming your hard drives or something. I had been using the internal drive for storing media files, video, music, comics. Does it matter where apps or files are stored?

Well, the "fix", IMHO, is to leave it with them swapped.
Yes, it matters where apps are stored and it matters what is mounted at /sdcard. Apps use space on the /sdcard partition for settings, temp storage, downloads, etc. Mounting that 5G partition at /sdcard instead of /emmc allows these apps to use that space rather than cluttering your actual SD card. And apps are going to wind up on your 1G partition, not on either the /sdcard or /emmc mountpoint.
You can go read up in my guide on my recommendation on how to best use this space. The normal way is inefficient and wasteful of internal memory, IMHO. But you know, maybe you like it that way

I think efficiency is more in how you choose to utilise the spaces rather than fundamentally in which switch option you use. For example, I choose to completely fill the 5GB of internal with sound and picture media as they get included in the normal app scanning process. Leaving the SD card to hold yet more media, app data and back ups.
It's still good to have the choice offered by the switch.

S5830i running out of free space for no reason

Hey all,
My friend just got his Galaxy Ace S5830i couple of weeks a go, and he isn't a phone\computer expert, i helped him install several apps on it (waze\whatsapp\tunein\ Facebook and.. that's it)
and the phone reports that he is running out of space, it says he have 20mb left out of 200mb, but he have 2gb sd card with 1.8gb free on it, it doesn't seam like there is any app that he can move to the sd, I attempted to use the app called "apps 2 SD", i got him rooted for this app to work and it says that there are no apps that could be moved to the SD card.
what gives? how can this be solved? how can i force move apps to the sd card or remove locked system apps that he doesn't use (like voice search, Google navigator\street view, alarm clock, memos etc, Samsung account related apps)?

I did, in the format of a program (app) that requires root permission, i therefore rooted the phone beforehand, and I did move 2mb worth of apps.
any other idea? perhaps the script you refer to can do something the app cant?

also try cleaning all the Dalvik cache it, I hope I have helped.

Did it just now, no effect what so ever, 167mb available, 23mb free, phone screams for space to be free, any nonlocked app is on the sd, most of the others removed, why did Samsung make a phone with total of 300ish mb storage is beyond me, the much older galaxy s 1 had 8gb in the cheap module, i mean .. come on didn't they think that a simple user might ran out of space by simply using 5 utility apps??
very very sad for my friend, which in turn is mad at Samsung, also shop dont accept return for any reason after 14days (which is inline with the laws here) so he cant do jack, i suggested selling it as "as new" condition with bonus of free screen protector, case, and the original box for say 70% of the new price.. not sure if he will even manage to move it that way :-\

You only tried one app. It may be buggy.
I'd suggest trying the Link 2 SD app. Just long click on any (user) app in the list then try to move it.

Look into partitioning sd card and linking apps to the partition using link2sd. This is by far the method that frees more memory in stock rooted devices.
To remove system apps you don't want:
Link2sd and/or titanium backup can be used to uninstall system locked apps.
Manually you can remove system apps by going into system/app with a root explorer (es file explorer is a free app for this) then delete the .apk and matching .odex files of the apps you don't want.

Method 1:
Use a App Cache Cleaner
Move applications with Link2SD
Link apps using SD partition and Link2SD
Use A2SD
Method 2:

Move Apps from phone to SDcard Using Link2SD
that worked for me

A phone...with 300 mb...i know roms worth a gb. I dont own a ace myself but i can tell you that if an app cant be moved to sd card via settings>applications>manage apps>[app name]>move to sd card then it wint move. Because some apps are made so that the files it accesses can only be in one big file. Some however (like some games) have 2 folders that it can access seperatly. Like save data and the game itself. One the save data is accessed it dosnt need to load any more information from the sd card. It will only re write the data. But with things like facebook it cant keep going between login details and app. Once logged in it keeps that information until you log out. If it part of it were in the sd card then it would keep telling you to re-log because it looses your data once it switches back to phone memory. Because of this most apps that require something that must be read all at once with app and login at the same time. Also the ace is low on ram. If you moved apps like that onto the sd card it would slow down as well. Apps like app2sd are kinda useless as it does the same as the manage apps part of settings. Even if you did move an something to sd card you would still have the app and needed data in phone memory so not alot of memory would be moved unless its something like a game as i said. The phone storage keeps the levels all in one. But the game data will unlock those meaning more game data space than app space. Or maybe you could try delete system apps with that there rooted device. Should improve memory quite a bit. Right now i dont even know how i wrote all this...but still. I say samsung mucked up if the ace has 300mb. My phone is only a wee bit better (0.1 inches...yes...you heard) and even my phone is alot better then this and the best part is...its a samsung! Anyway. I hope i helped you.

Thank you all for the replays !
I have downloaded titanium backup and with it I am backing up bloatware and then uninstalling it (and then moving the backup out of the phone and to my friend's computer.. just in case)
next up I plan to follow the wiki in regards to SD card partitioning:
http://forum.xda-developers.com/wiki/SD_card_partitioning
in order to format the sd card to two partitions, data partition (fat) and ex2 (if i understand correctly) so that I could link apps to that parttion (the ex2 one)
and then I plan to use link2sd to link app's data to said partition
https://play.google.com/store/apps/details?id=com.buak.Link2SD
then I plan to uninstall link2sd as its not neccery for day to day operation.
and then I am going to check that app moving script here:
http://forum.xda-developers.com/showthread.php?t=1591079
to see if i can get something out of it
just as an FYI, the phone got 384mb (according to the wiki) out of witch only 220 is visible, and stock status (first boot up) + whatsapp\waze\tunein\facebook\shazam .. the phone sits on 196mb used and 24mb free, at which point it screams for space, that is the source of all the problems of this device.
not to mention the low ram quantetiy, which in theory shouldn't even be a problem as long as you use one app at a time (no tunein radio while facebooking, for example) which is acceptable.
again, many many thanks for all the helpful replays ! !
I am going to post an update once I am finished with titanium backup root (free).
* in regards to formatting\reparttioning the sd card, did i get my idea right? its part FAT (for pictures and mp3 files) and part Ex2 for apps, so from a 2gb memory card I could in theory get away with 1500mb FAT partition and 500mb EX2, assuming I plan to not install any additional apps and just need some breathing space (23mb is clastor****bik to say the least)

I even went as far as to find the startup\shutdown sound files and replace them with one byte (1/1000 of a KB) size silent file to save additional ~150kb.
I removed oh so many system apps and Samsung bloat ware nonsense, googled some safe-list apps posts made on xda and used them to guide me as for whats safe to be removed, live wallpaper, Samsung accounts, all share, duel clock and many others are now gone.
and I am now on whooping 25MB free with 165MB used, nothing else to do, used all apps and scripts I simply cant free more space.
the free space error msg is gone now, the phone can receive SMS messages once more, but few Waze updates and some more sms and I am not sure how well will it be :-\
my friend is so furies at Samsung, as am I :\

Thanks, done that now, but that is not the problem, the problem is only having 25mb free as is, even with new pictures saved to the sd card and new softwares install to the sd card, some stuff simply stay on the internal memory and the only thing left for me to remove is the internal screws of the actual phone.. thats how far i went with this :-\
My guess right now is that Samsung had chips of 384 (or maybe 256+128) left over after a production of some phone got stopped so they figured it would fit perfectly into entery level phone .. cant say that i am happy with there result.

deleting unnecessary stuff out of system folder - Android 11

greetings community,
i have tried to search it, but being pro newbie, I found nothing. Is it possible to make this folder little bit lighter it takes 22gb of space, and my poor phone has only 64gb
I have rooted devices
thank you in advance

You can delete some apps using root file manager. I've use root explorer and have for years but nowadays there are times where it will not allow me to delete some apps (YouTube, chrome are a few this has happened to me on..) that my phone will NOT allow me to. And yes I have magisk and root explorer pro has root permission when this has happened. One way to get these apps off when this has happened to me is use another root file manager. Amaze file manager did the trick. I was able to delete apps I could not with root explorer. I'm BIG on not having useless bloatware on my phone so disabling apps is NOT my style. I usually save a copy by making backup and throw the backed up apks on my laptop or a USB thumb drive and delete whatever in case I end up deleting something that messes with my phone...Far as what can be deleted and what can't you can just discover for yourself. That's what I've done. I'm currently on a custom rom and I normally don't do much deleting unless I'm using the Google stock rom. If and when I do wipe more off stock I'll return and give you a list of what I did clear out. Just look in /system/app, /system/priv-app, product/app, /vendor/app with a root app and go to town. That's what I've always done. I believe TWRP for Android 11, the test build that bigbiff dropped about a month ago works now to make backups so that would be something to maybe do before hand in case you end up needing to restore your rom. On a few other devices I've owned people would sometimes make a thread on here for apps that can be removed and all and then list what they took off and what not to. I believe this Is what you are talking about.. If so hopefully it helps
Far as making system folder smaller and not meaning apps I believe it's possible but I think maybe you would have to repartition your device to do that and although it's possible it's dangerous. One wrong move and you have a paper weight doing that. I messed up my original Pixel XL because power went out while I was doing it before I was done and it was a goner. If anything I say here isn't right or there is more information about this please someone share who has more knowledge of this sort of thing. I would love to know as well. Good day/night to all. Cheers.

You would be better off deleting excess files, trash, and photos that are already backed up. The system partition can be mounted and some files removed, but for the most part it is a minefield. Google has a fantastic new tool (since changing Photos retention rules) called "Takeout" that allows you to back up the contents of many parts of your phone and allows you do d/l it in compressed format directly to your PC. Check it out. OTHERWISE- If you simply must carry large files like movies, music database, pictures etc. then consider getting a USB-C OTG drive.
https://takeout.google.com/

This is why you get a phone with an SD card slot.
You then use the SD card as your data drive.
Only the apps and temporary folders go on the internal memory.
Next best thing is a flash stick or use cloud based storage which has downsides to it. Even if your internal storage is huge you don't want to store critical data there. I use about 64 of my 500gb of internal vs 340 of 500gb on the data drive.
If a large data base is on a large internal memory a data restore takes... forever. Most times the SD card is spared in OS crash and burns. Plus it can be used to restore the OS drive apps and settings.
Much of the above doesn't help you now but it could with future devices. All my PCs even my laptop are configured as dual drives. I learned a long time ago it works well, saves sweat and data.

A lot of photos disappeared, nothing is working to recover it

Hi, yesterday while looking at my gallery I noticed that a lot of photos are missing, for example, my Italy trip photos and videos are gone, not all of them though, there are some left, but videos are all gone. I didn't delete or move them, didn't touch them at all, it just disappeared. I've tried looking at my Onedrive, Google drive backups, but they are all showing current photos, that I can already see. I've also tried cleaning gallery and media storage data in settings or deleting .nomedia files (which cant be actually deleted), but no results. Booting on safe mode, using different recovery software also shows same photos that I already see on my phone. Tried to get help from Samsung Support, sadly they are as competent as I am, all the suggestions were already known. They did suggest to factory reset my phone while backuping everything using smart switch since there might be some malfunction and doing so all the supposedly hidden photos gonna be released. Not really trusting it though, because in backup I can clearly see that the photos that are being backed up are the photos I can already see, and no hidden files are being backed up. I've also restarted my phone like 6-7 times in different circumstances and noticed that everytime my phone boots it loads up 196 pictures in my camera roll, and then after some time the other part of it gets load up. So my question here today is: Is there anything I haven't tried and is it possible to recover the hidden/disappeared photos?
P.s. the photos that I'm concerned about is in my internal storage not in SD card.

After you lose data it's many times to late to do anything. Why aren't you using the SD card as a data drive to at least backup your critical data?
That in turn should be backed up redundantly to at least 2 hdds that are physically and electronically isolated from each other and the PC. Consider this a wake up call...
This isn't looking good. Backed up what's left, now. Try in safe mode.
It may be malware, in any case it sounds like it's factory reset time if you can't ID the root cause.
If you added any downloaded images* to the folders losing data it may be a malware jpeg, if so this jpeg must be deleted or it will continue to destroy and mutilated files in the folder it occupies. I've seen ones that do this in Android. Think. What was done, installed or downloaded?
*All downloaded jpegs should be kept in the download folder until vetted. This will help limit the damage hopefully to just the loose files in there. At least open the jpeg there and look for abnormal behaviors in that folder because you add that jpeg to your database! Antivirus may not detect these little buggers... WYSIWYG

Okay first of all, One drive should be responsible for backing up my data, thats why its there, no? I do understand that data back up need to be taken more responsibly, but again why would I keep everything backed up from my phone since everything in there is just basic daily use things, nothing that much of importance, except of course memory photos in my camera roll (which again SHOULD be backed up in my one drive). Second, if I were that careless as an IT student to download malware into my device, why would I move it to my camera roll folder ? (thats the only folder that has photos and videos missing). Third, I did factory reset my phone with a back up from Smart Switch as suggested from so called Technical Support specialist from Samsung, sadly the results are same (All photos I had before factory reset are there, no actual recovery has been made).
Sorry if I might sound rude, but I'm really frustrated. Samsung really let me down big time for the first time in 12 years of using their products.

I feel your pain as I lost an irreplaceable database myself at one point that was 30 years old. It sucks.
The only backup I trust and use is copy/paste/verify for size and if readable.
SmartSwitch can fail you miserably, never use it for critical data... same with Google junk.
In unencrpted hdds I trust.
Maybe your Google account was hacked... again always suspect malware, viruses, rootkits if unexplained behaviors are observed.
If you had a previous SmartSwitch backup saved that probably would have worked. At the time what the Samsung rep told you in lieu of the former was your best shot probably. The data was already lost unless its backed somewhere you overlooked or forgot.
It's also possible you could have a hardware failure in progress, keep a close eye on the device.
The reason I back up they way I do is from hard lessons learned going back to XP Pro and other OS's. Also never clone (copy/paste only) or encrypt data drives. Always use a good SD card that's V30 rated like a Sandisk Extreme. All critical data goes here, and everything you need to do a full reload including installable app copies. App that allow settings to be saved like Poweramp, contacts all go on the data drive as do vid and music libraries. ColorNote will save it's backup directly to the SD card, it's a very useful that can used for bookmarks. Don't forget all passwords as well.
Keep the DCIM and download folders on internal memory. Only these and installed apps go on internal memory. Periodically backup the DCIM files to the SD card but DO NOT use the phrase dcim in the backup copy folder name... and then redundantly back up the SD card periodically. Best to time stagger these backup between 2 or more hdds. Develop a plan, put some thought into it. You have all the hardware you need for a robust dual drive device if you use it!
I have 2 N10+'s and this is how I run them. Zero issues.

@blackhawk. Agree... Never trust Google Photos. Somehow I also lost a lot of my photos. Mostly the ones that I shared (as file). Was that because I deleted them directly using Root Explorer? No. Because I downloaded them to Restored folder and deleted through Explorer? No. Because I deleted them from Sent folder of WhatsApp? No... I tried each one of these and couldn't consistently delete the items from Google photos... But how? Why? Just don't trust the application.

Always redundantly backup critical data and verify it's size is correct, it's readable and complete. Copy/paste only, never clone media files ie music.
A drop, malware, hardware failure, a near lightning strike, a boot loop, a user mistake etc can destroy data instantly. Expect it will happen because eventually it probably will. No such thing as overkill with data backup. Multiple copies in different locations that are time staggered and not connected to a PC preferably on hdd. An earth grounded safe or metal box is ideal to store them in at 50-70F.

Great advice! I see these posts about lost data, and people don't realize, you have to backup this data somewhere. The FIRST step is something like Google Photos or Amazon even. But these are not enough (it's a start, at least).
General recommendation is a 3-2-1 backup, as detailed here: https://www.backblaze.com/blog/the-3-2-1-backup-strategy/
Bottom line, if it's something you don't want to lose, then have a REAL backup beyond just GPhotos or similar.
Especially in today's world of cellphones and flash-drives. Both are easily lost or damaged. At least in the old days you can sometimes recover data from spinny drives (I did a LOT of this work for people, using specialized software)... but flash drives don't work the same, and they likely fail to read completely, leaving ALL the data gone in a flash (pun intended).
Backup, BACKUP, BACKUP!!!
EDIT: Also note, if you use something like Gphotos, you can very-easily download ALL the photos from there. This makes it rather easy to backup those files by simply copying that ZIPped file as necessary. You'll have to do this manually every so often, but it's quite easy to do.

This same thing just happened to me. All of my folders including my camera pics were deleted, except my downloaded folders. All the photos are missing from my backups, all trash bins are empty, and Samsung Customer Service suggested that I do everything I had already done. I thought I'd be fancy and get the ZFold 4, which doesn't have an option to use an SD Card. I even downloaded a recovery program to my laptop and it couldn't find any photos. I'm currently waiting on an adaptor, so I can download photos from my last SD card in my previous phone. I've never been more angrier with a phone than I am right now.
