Samsung WhatsOn Video won't unintsall/disable


I tried to uninstall/disable it but the "Disable" and "Show notifications" are greyed out -- I have no non rooted phone. I am running Android 4.2.2 on a GT-19205 Mega. Note that the normal "Whatson" app can (and is) disabled.


Anything I can do to get ride of that annoying bloatware?





Creating and enabling an internal storage swap partition on rooted Android Kitkat


System: Rooted Android 4.4 phone (actual rom: CM 11 Milestone 6) with 1GB ram, plenty of internal storage, but no sdcard slot. My phone's partition scheme is unmodified CyanogenMod 11.


Problem: lowmemorykiller/OOM handler on my phone keeps killing vital system processes such as the lockscreen, or incallui, or acore, causing at best long freezes, and more often soft and hard system lockups. I'm probably running apps that push RAM beyond system minimum, and it's making a suboptimal choice of background process to kill. I looked into fine-tuning lowmemkiller but got nowhere.


As ram and not CPU is the issue, I want to try enabling internal storage based swap instead of zRAM as a workaround, which the phone should handle. But I can't find clear instructions how to do so. Every instructional page I found is either desktop not Android specific, external (SDcard) storage specific ("partition using USB+windows"), assumes you want file not partition based swap, or suggests a Google Play app to use. None explain step by step how to actually do it.


Assuming I've read the warnings and know the risks, and want to go ahead anyway, how do I do it? I really just want to get a list of the example console commands for using partition-based swap. I assume it goes something like this:



  1. Resize existing partition(s) or subpartition(s) to create spare space for a dedicated fixed-size swap partition.

  2. Create or define a new partition in the free space, and ensure it's formatted as swap, or the OS will format or use it as swap on boot.

  3. Edit some other system files to ensure swap will be mounted and enabled appropriately on boot, so the OS can recognise and use it. (fstab, or something else?)

  4. Disable or deprioritise zRAM, and edit swappiness to about 20-30.

  5. Reboot, cross fingers, and hope I did it right.


My current *nix experience level: I know Linux uses partitions and subpartitions, that new partitions and partition changes probably need me to manually edit fstab or other files, and manual edits may also be needed to ensure partitions will be mounted/enabled/used at boot. I'm haven't used the actual commands or changed the actual files so I don't know what to expect. I'm comfortable with console, but this is a bit of a new area for me.


How do I do this, step by step, and what are the commands I'd use if they aren't obvious. I can figure the rest from that.





Emulating a factory reset


I would like to prevent a user from factory resetting their Android phone. How can i do this?


Or better still, I would like the factory reset to not do a factory reset, but instead, just re-run the initial set up wizard, thus not affecting any apps already installed. This way it seems like a factory reset has been done.


The phone is a Samsung S4 If anyone can assist, I would be a very grateful concerned parent.


Thanks

How can I extract or backup data (the path+filename) from playlists generated with builtin MP3-player (from Samsung s3 mini to Windows)?


I like to backup playlists (and possibly edit them on the PC) I've created via the Samsung s3 mini's MP3-player, since I have trouble with the way the smartphone deals with them:


Whenever I remove the SDHC memory card (after turning off the device of course), and re-insert it, then it forgets all files in the playlists which I have created with the built-in MP3 player (I want to create playlists while I am travelling in the train - so it is not of much use to create M3Us externally and put them in a folder of the SDHC card).


Now I have bought a bigger memory card, transferred all MP3 files to it and want to use it in the phone as replacement of the smaller card.


So I am looking for a way to backup the playlists (not the entire MP3 files, just the list containing the file names and path) and use them with the new memory card (paths are exactly the same, just more space available). Shouldn't be a problem, I thought, but Samsung made it complicated.


The phone has a playlist folder, containing the Playlists, but when I use a USB cable to connect it to the PC, I can see them (*.pla files) but they have 0 bytes and cannot be copied. Also, if I connect the SDHC card via cardreader, the files aren't useful.


Samsung Kies also did not work for me, it does not seem to support the playlists created on the phone.


I found this interesting question, which explains that Android stores playlists in SqlLite databases, but unfortunately, on my Samsung phone I could not find the database file (although there is a folder Computer\GT-I8190\Phone\Android\data\com.google.android.music which should contain it, but no databases subdirectory and no database files).




So to summarize my question:




  • Do you know how I can backup the playlists or extract the file/path info contained in them?




  • Or do you know if there is a tool available (for Android, or for Windows reading it from the mobile phone) converting the playlists into a compatible text format (like .m3u playlists)?

    (Note: The other way round it is possible, as this forum post explains)




Your help is much appreciated!
