Can't move apps to SD card (Links2SD not supported on this phone?) - Moto G 2015 Q&A, Help & Troubleshooting

I've been trying to move apps to my SD card using Links2SD, but apparently this phone doesn't support moving apps to the SD card. Is there a way to do this?
I also tried "linking" apps to the SD card (even though I'm not quite sure I understand what that means), but I'm getting an error saying I don't have a second SD partition. If this is my last hope, how do I create a new SD partition?
Running Resurrection Remix on 6.0.1.
Thanks!
Edit: found this thread on creating a second partition, but I'm wondering if it's possible to do it on the phone since I don't have a card reader.

I think you can use TWRP to partition the SD card... A ext2/3/4 partition is required to use Link2SD on any device
Note that you cannot use the card as adopted storage. Always set the first partition as FAT32 and the second as ext4, or the card cannot be read in some Windows PC's, I would recommend a minimum 32GB card and at least U1/UHS-1 speed rating for acceptable performance.

Formatting Question?

Hi all,
I have been reading about an issue that I have: 'android.process.media' keeps stopping.
One of the suggestions is that there maybe a corrupted file on your external sd card.
The fix is to either delete the file; good luck trying to find which file. or to reformat the sd card.
Since I have the keyboard dock and several 32gb microSD cards. I plan on copying all my files to the other card and then formatting the card in question.
However, it seems on the Asus tablet, I am not given the format option. I had it on my Samsung phone before the upgrade to ICS.
But one thing I wanted to do after some other reading is to format the card the same file system that is used on the internal memory.
If I have my facts correct, the internal memory is formatted as 'ext' and external SD cards get formatted as 'fat' (or is that fat32).
I think it's formatted as fat, is for compatibility with your PC.
However, the article, said that 'ext' is much more secure and less prone to corruption.
So is there anyway to format the external SD card in this 'ext' file system and how would one do that process?
Thanks!
Rob
You would need to do it in linux or find a windows program that could do it, as ext is not supported in windows. Im not sure the microsd will work right in the tablet formated as ext and your windows desktop wont be able to access .
Ok, I read in another thread, they suggested to put the microsd card in the phone and format from there.
I did do that.
And I have another question, my phone is rooted and it contains CWM.
I noticed in CWM, that you can fomat from there.
There are options to format areas, like /system /cache and the one I am interested in is /sdcard.
My question is this, is this /sdcard the external micro SD card or is it simply the partition /sdcard which is Samsung's internal memory. I don't want to take a change and format the internal SD card.
I think once formatted the external SD card, but I was on a different version of CWM, I have a different one after the ICS upgrade that was recommended by someone helping me do the ICS upgrade.
Anyway, thanks in advance!
Rob
Whoops almost forgot, there is thread on xda about formatting memory in ext4. I would like to try that and see if the Asus tablet can read that if I get to format the external card in ext4 Still looking for a Windows program that will format in that mode.
/sdcard is internal. /Removable is external.
I would be surprised if you can find a Windows program that reads, let alone writes, any type of ext filesystem (and forget about anything less mainstream like JFS or ReiserFS). Microsoft only made Windows compatible with their own filesystems, FAT32 and NTFS.

To understand what partitioning an SD card means, you have to know what partitioning is in the first place. Partitioning is the act of dividing some kind of physical device, either a hard drive or in this case an sd memory card, into multiple logical devices.
If you had a brand 10GB hard drive, it would come with only one partition, C:\ which totaled 10GB of space. But if you split that hard drive into 2 partitions of equal size, you would have a C:\ and a D:\ drive, each totaling 5GB of space. Partitions don't have to be of equal size, and they don't have to be in the same format.
Now for android, most times partitioning an SD card is used to gain more space to store apps. If you create a partition on the SD card which is formatted in ext2 ext3 or ext4, you can link apps to that folder to free space from your internal SD card.
An example of this would be if you have no more space left in your internal memory for say, Angry Birds. You could partition your 8GB SD card into a 1GB ext3 partition and leave the rest in a 7GB FAT32 partition. In this way, you could use an app like link2sd or app2sd to move apps to the SD card to free internal memory up.

If you flash a new Rom, you will be formatting the internal flash memory as well as the apps partition on your sd card. In my example, the 7GB partition will be completely unaffected.I would be careful though, there are ptions in CWM recovery that do allow you to flash the 7GB partition. However, if you just do a simple wipe data/factory reset from CWM, your data will be safe.

There are a couple steps missing. Continuing from the hard drive example, the 8GB SD card would have 1 large partition, formatted as FAT (or a variant, such as FAT32). The internal memory space of the Android device is formatted as EXT (or variant), as Android is Linux-based. Android is designed to recognise FAT as "foreign," and EXT is seen as "native." Therefore, we can trick the OS (Android) into thinking there's more drive space than exists physically in the device, in the following way: Repartition the 8GB SD card to 2 partitions, format the 1st one as FAT, & the 2nd one EXT, then tell the OS to use the 1GB EXT drive to store stuff that's normally only put in internal "native" memory. In Windows, this is called a shortcut, & in Linux it's called a link. So you link a folder from the internal memory space to the 2nd partition of the SD card. This is managed quite easily through apps like link2sd, as mentioned previously. The OS (Android) doesn't know that the linked data actually resides on external memory.
Theoretically, you could link the entire everything to a gigantic SD card, and, in a way, that what people did when they rooted the Nook Color. This would give you tremendous space to play with, but does have potentially significant limitations.

Using one large SD card was also what I did with my first android phone, the LG Optimus V. It didn't have a real large internal memory space, so I used a class 10 SD microSD card to supplant it. Also, if you want to get truly technical, what link2sd and other similar apps are doing is creating what is called a hard link.
A shortcut, or rather a soft link, differs from a hard link in that a soft link appears to the OS as a shortcut. Meaning the OS knows that the file resides on another storage location. By using a hard link, the OS is not aware that the file resides in another location.
For example: Say you have the following setup
SD Card Partition 1: [/mnt/sdcard-ext/data] (For apps)
Partition 2: [/mnt/sdcard] (For everything else)
Internal Apps: [/data] (Normal app location)
If you wanted to move "/data/angrybirds.apk" to the SD card using a soft link, you (or an app) would have to move "angrybirds.apk" from [/data] to [/mnt/sdcard-ext/data] then create a soft link to "/data/angrybirds.apk".
However, the problem with this approach is that android doesn't accept soft links in place of application files. So to trick it, you create a hard link by the same method above. But this time, because it is a hard link, to the Android OS, the file doesn't appear to have moved at all.

Also, I forgot to mention that the class of SD card you use is very important. Cards are ranked from 2-10 with Class 10 being the fastest(1). If possible, I recommend buying at least a Class 8 card if not a Class 10 card. They are not available in most local shops, but they are available online for cheaper than the store would have cost anyway.

Partitioning will format the card and erase everything, so backup your sdcard! Like anything on here, make a backup before continuing, but for this, make sure you're backup is on your computer, not your phone.

Actually, those speed ratings are measured using burst read/write, so are most reflective of performance during operations with very large files. Typically, a higher class rating is associated with higher speeds with large files, but a slower speed with small files (~4kB). Hence, the recommended class rating of SD card depends on the intended usage: highest class affordable for high resolution video, while class 4 or 6 for reading/writing many small files (e.g., mobile phones).

Thanks a lot guys For replying and letting me explore more about partitioning! So which is a better app to control partitions? A2SD or Link 2Sd?
Does partitioning causes any harm to OS....?

You cannot repartition the internal memory, so your question only applies to the external memory (SD card). Partitioning by itself only makes 1 "disk" appear as multiple "drives". So the real question depends on what you do with the partitions. Most people are satisfies with creating 1 additional partition, and using any of the many available "2sd" apps, which will do the hard work of creating the links (=shortcut, remember?) into the 2nd partition.
Basically, pick one and go with it. Remember that repartitioning your SD card will usually obliterate all data on it. Backup, backup!

I would say it depends on your situation. Link2SD will let you choose what apps you want to be on the SD card. Apps2SD will put everything there. Also, Link2SD has a GUI you can use to move apps, where Apps2SD is done in a command line. So honestly, I would recommend Link2SD. It's free in the market.
As far pas whether partitioning harms the OS? No, it should not. that said, I would always make backups of everything anytime you have a fear of losing data.
If I switch to some other phone what will happen to my Partitions....?
Sent from Galaxy Ace running ICS!
Partitions where? The partitions on the phone's internal memory will stay on the phone, and the new phone will have its own internal memory (I hope this is obvious). The partitions on the SD card will stay on the SD card. If you put the old SD card into the new phone... well, then nothing happens to the partitions. It's like taking a hard drive out of 1 computer and putting it into another.

Some stock ROMs do not have support for ext, so they will not be able to access any partition which has been formatted ext2/3/4. Therefore, if you have one or more partitions on your SD card which are formatted as ext, you are not guaranteed that the new phone will be able to read it. Of course, you can flash a new ROM (CM, MIUI, etc.), and the new phone will be able to read ext format.
Also, if you make a 2nd partition on your SD card for the purpose of using Link2SD, a2sd, or whatever *2sd scripts, your new phone will not know that you have apps installed on that partition, until you recreate the script to mount that partition during boot.
What is swap partition and what are scripts ...?

I have never used a ROM, stock or otherwise, that hasn't supported at least ext2/3; though your mileage may vary. Most if not all ROMs should be able to use these partition types. However, ext4 is a fairly new partition type, and does require special care to make sure the ROM/Kernel supports it.
Again, before you do any rooting, ROM'ing, or partitioning, you need to do your research and if there is any hint or fear of losing your data, back it up. Make sure the ROM supports the filesystem you intend to use. There should be a changelog / list of features on the thread for your ROM telling you exactly what is in it.
How many types of partitions can be made?

[Q] SD CARD Partion

Good morning all !!!!
I have done an ample amount of reading and I am still confused by the topic a little bit. And the post I came across were rather old. I just bought a 32G micro SD card for my galaxy s 4g running (wicked rom 9.1). This rom finally has the ability to move apps to SD. My question is, is it really necessary to partition your SD card for any reason??? What are the benefits? I still do not get he concept. I can only find the ways to do it. but not the reason.
*BUMP*
so.... I still did a bunch of reading, and did a SD card wipe attempted the 2nd partition and using link2sd and seems that the 2nd partition is not being recognized? can someone point me in the right direction?
Partitioning the SD card!
Actually, partitioning gives you the benefit of using space in your SD Card to install apps or use app data, instead of cramming it all up in the phones' internal memory. In other words, the Second Partition acts as the internal memory of the phone. So creating a 1 GB partition for a device with low internal memory allows the user to install more apps and doesn't let the internal memory decrease.
Link2SD can only accept partition with the proper scripts, i.e if the SD card has been partitioned with Ext2 then Link2SD must also be given the command for creating scripts as Ext2.
It is usually recommended to partition SD as Ext2 or Ext3 and create scripts on Link2SD as the same.
Hope it helped :good:

TWRP partitioning external SD doesn't work (Unable to locate device to partition)

Hi,
since the internal storage of my 8GB Moto G3 is pretty small, I wanted to move apps to my external SD, but there is only a hand full of apps I can move.
So now I wanted to partition the external SD I have, but when I want to start the partitioning, it says "E: Unable to locate device to partition".
When I google for exactly this error message, I can't find any solution. I formatted the SD via the phone, I also formatted it via PC to FAT32 and exFAT and I formatted it via TWRP to exFAT and also to EXT3 and EXT4, none of these methods worked.
I also tried it with the MicroSD mounted and unmounted, made no difference.
Also can I make the external SD to the main storage for the phone, so all apps put their files on the SD card like Whatsapp, without symlinking every folder manually?
All apps won't move to the SD. I'm guessing that if the developer specifies internal, that's all you get. On the first soak you could force apps to external which I tried with mixed results. A few would work, some wouldn't. Even on the latest, some app's widgets won't work if the app is on external.

HELP! EXT2 partitioned microSD card cannot be read by laptop

Hi there. I'm using a Xiaomi Redmi 1S with 16GB SD card. Previously I had partitioned my SD card with 2nd partition set to FAT type, which I used to link apps to SD card using Link2SD. My SD card could be read fine by my laptop when I plugged it in to my laptop with a USB connector (i.e. I could open both my internal storage as well as external SD card storage). Recently I had to reformat the SD card due to some issues with my phone, and I hence deleted the old partition and created a new 2nd partition in EXT2 format instead. The 2nd partition is readable on my phone and works with Link2SD to link apps to SD card like before, however when I plug into my laptop, I cannot see the SD card storage. I can only see the internal memory storage. Please advise how to fix this, if possible without reformatting, as I am unable to move files to and from the SD card storage if I can't see it. Thank you!
