Moving apps to SD on Samsung S7562 Duos

Only for a rooted Samsung S Duos

We can finally move the apps to SD card on Samsung S Duos. This mobile has a usable Internal Memory of 1.5 GB. However after using about 800 MB of it on a stock S Duos we can no longer install any apps strangely. It will throw an insufficient storage error on Google Play and another memory error if you try to install apk files through file explorer. There is a work around but unfortunately/fortunately the mobile has to be rooted to implement it. There is no other mobile I know which needs rooting more badly than this! Also by default none of the apps can be moved to SD card. In fact the phone is so dumb that it cannot differentiate between Internal and External Memory(extSdCard/SDCard). I even used an app which swaps the internal and external memory but after a reboot things got messy. And more importantly even after swapping I was unable to move apps to SD Card. So I will not recommend that app “External 2 Internal” which was mainly released for this annoying mobile. Also it is always a bit risky to have SD card as main memory. Hence I dropped that idea.

How else can we move apps to SD?
This is what worked for me and it doesn’t need a memory swap so read on….
Obviously what we need is Root access first.
I will not be covering the process of rooting here. You can refer to XDA or other online sources for that. It is quite simple once you make up your mind.

After rooting you will need to install a bunch of Root apps. Start with Super SU as an appetizer. This app will grant root access to other apps that will tune your mobile later.
Install ROM Toolbox (Lite or Pro doesn’t matter) and Swapper 2 from Google Play. Finally install Link2SD which is what we will be focusing on in this tutorial and will be doing most of the dirty work. Download MiniTool Partition Wizard for PC.

Alright we are ready for the next tedious step (depending on the size of your SD card and the data in it).
Connect your mobile to PC.(Make sure USB debugging is disabled). How easy but wait its long and boring. Start copying ALL the contents of your SD card and back it up on your PC somewhere. If you have any folders hidden in your SD card make sure you unhide them before backing up. Get a cup of coffee or whatever and sit back and read this tutorial till the back up is complete. Also meanwhile you can download this PC app MiniTool Partition Wizard and install it on your PC.

Once the back up is complete and the boring part is over we will be formatting the SD Card and creating aleast 2 partitions on it.
Disconnect your mobile and remove the SD card. Use a Card Reader to connect it to PC or your laptop’s SD Card slot to insert your SD Card into it.
Launch MiniTool Partition Wizard from your PC. Look for your SD card’s partition. Right click on it and delete/format the partition. All the space is unallocated.
Again right click on Unallocated space and “Create” new partition. Select your size in such a way that you have atleast 2 to 4 GB left for the next partition.

Create a PRIMARY FAT32 partition. Leave the cluster size as default.
Apply Changes by clicking the tick mark on the top left corner.
Wait for it to finish. Right Click on the remaining unallocated space and create a PRIMARY ext3 partition. I used Cluster size as 4KB for this one. Apply the changes!

Okay the SD card is partitioned and ready for duty. Before you insert it into your currently worthless S Duos copy all the contents backed up as it is in your FAT32 partition of your SD card. You wont see the other ext3 partition anyway so no need for confusion.

Insert the SD card back. Reboot your mobile. Goto Settings -> Storage and you will notice a reduction in the size of your SD card. Don’t panic. The card is partitioned and the dumb phone cant see it yet. But I am sure you can!

Next launch Link2SD (atlast).
Grant it Superuser access!
Immediately it will pop up a screen asking you to select your 2nd partition. Select ext3. It will say reboot so obey it and reboot you mobile.
Launch Link2SD again. Click the menu key and select the Storage option. You will see something like this if all went through fine:
You will see a 2nd partition here.

From here on you will start moving apps to SD.
Using the filter option display the apps you installed on the Link2SD page.
Click on any app and it will show you a button called “Create Link”.
Click on it and check all 3 boxes and move them to SD card!
Thats it. Use the same steps to move all your apps to SD. Do not move System apps and those that have “ODEX” next to their name. Its just my recommendation but you can move them at your own risk.

In the next tutorial I will show you how to tune CPU and speed up your mobile using Swapper 2 and ROM Toolbox.

VLC Player alternatives

We all know VLC player is used by a vast majority of people simply because it supports most video formats. What VLC does is it amplifies volume by upto 4 times a normal speaker can handle. This is fine with desktop speakers. But with laptops sometimes 400% volume is too much and eventually the speakers will start making crackling noises and stop working completely. This is exactly what happened with my HP 500 laptop. I also found out that this happens regularly due to VLC. Hence I uninstalled it.
There are many alternate players available and after some research I managed to find a perfect if not a better alternative. The K-Lite Media Player. I had used this player before but was not aware of its complete power. This player supports most formats if we install the right codecs. Also it supports and downloads subtitles for any video format including .m2ts format which is not supported by VLC. Here is what you need to do:

  • Install the latest K-Lite Media Player Classic.
  • Install the DirectVobSub_2.41.7259_x86 (for playing subs).
  • And finally install the Combined Community Codec pack for windows media player.(supports all major video formats)
  • Rename the downloaded subtitle file to the same name as the movie file or download the subtitle while playing the movie!
