Problem with OTG flash drive. - G4 Q&A, Help & Troubleshooting

When I try to open via file explorer (because apps just don't have acces to the memory like it wasn't connect at all) a video/music files from external memory with non-stock app (VLC for example), an error occur that tells that the file can't be open. When I choose stock video player everything works fine. Also all non-stock apps have granted all permissions, so why it does not work?

How to install apps?

Hi.
I am new to Android and need your help.
I can not find files or file manager in the apps confused.
do I need to download anything to be able to do this?
And I do not know how to install apps if I copy one from my mac to the phone.
Lastly, I also do not understand why my mac can not see the folders of the phone even though it is connected via usb.
Finally, I tried to transfer data via bluetooth, but again I did not manage.
It says time over or something I do not know.
It looks very basic, but I need your help.
Please , help.
There is no default file manager. Most people will never need one.
If you want one, search the market for one, there are dozens. Astro is very popular.
to install ones you copy over, you need to go to home>menu>settings>applications
tick the box to 'allow unknown sources'
then, in whichever file manager you download, open the APK file on the card and it should install.
You can only browse the files of the SD card. the phone memory is system memory and protected. you do not eed to access it. All storage is done by the memory card, not the phone memory.
Bluetooth functions are limited on android. you can send files (as long as they are files the phone supports i believe) but you cannot use isync or anything like that.
If you want more sophisticated sync options for android, have a look at the missing sync for android at www.markspace.com
simples.
Thanks.
I downloaded Astro and it seems nice.
Now I can see how it works little bit.
Thanks for your help.

apps won't write to internal storage

Hey there, I'm having a weird issue with apps not being able to write to internal storage. I'm using stock rooted 4.4.2, things work after a hard reset but soon after es file explorer shows that my home directory changed to storage/emulated/legacy instead of /emulated/0 and things just dont work correctly. Eg. Instagram gives me an error, snapchat, Baconreader and imgur also fail to save images. I did use sd write fix, dunno if that could cause any issues.

[Q] Use MP3 ringtone from internal memory

Hello.
I have a problem. I have my own set of Call and SMS ringtones in MP3 format.
Unfortunatly when i connect my phone to computer in data storage mode (works like pendrive) phone access to SD card is severed and because of that ringtones are being set back to default ones, even if i disconnect my phone from computer.
Changing phone mode to media device is not an option.
The solution im looking for is a way to copy my MP3 track to internal memory and then select it as ringtone. With that if i would connect my phone to computer as storage device, my MP3 ringtones would remain because they are now in internal memory.
I dont have problem with copying MP3 to internal storage. My phone is running official Andorid ICS 4.0.4 with full root access (i have superuser and i can use apps like Link2SD etc.). Im using X-Plore app for file management, i can access root with both read and write.
The problem is even if i place my MP3 files in internal memory (tried a few of different places) when i select ringtone and then i press "phone library" phone wont find my MP3. Same happens if i want to play them in stock media player. It does not see them.
So my question is how to make my phone see MP3 files stored in internal memory?

you need to place you sounds in the corect folders
for ringtones: /system/media/audio/ringtones
for notification sounds: /system/media/audio/notifications
then reboot & see if you can choose them from settings/sounds..
if you cant then you have probably convert to the same fileformat as the other inside (i think its ogg), which is a simple task

Accessing ext. SD-card via Wifi

Hi all,
I like to acces my phone via WIFI to upload & download files to it . I use the Websharing App to do this and this works quiet well via a browser on my computer.
However when trying to write a new folder to my external SD-card in my phone, i get an error. I Tried this with different filesharing apps, but i seems like i don't have persmission to do this because i always get the same error.
This problems occurs only when trying to write something to the external SD. Reading & copying is possible.
Does somebody knows how i can fix this problem ?
When connecting the computer via usb-cable , it's possible to write directly to SD card.
(Samsung galaxy s4 mini LTE, android 4.4.2)
Cheers.
On android 4.4.2 3rd party apps can't write on SDCard. You must root Your phone, install Xposed Framework and then download and install module KitKat SD Card Full Access. Also better way to browse and manage files directly on Your phone is SambaDroid, You can even manage system files.

Okay thanks for your help. Will try sambadroid, otherwise will check the xposed framework. Phone is already rooted.
I'm afraid that You also need this xposed module for Sambadroid to work. As I remember it was some build.prop modification to make it work if You don't wanna play with xposed.

CM13 + USB Drive?

First I backed up all my apps onto a USB drive using Titanium Backup, than I updated my Nexus 7 to CM13. I can't get the USB drive to mount to the system properly so I can restore all my apps. I've done all the things that TB needs such as enabled root access, etc... The system recognizes the drive, and I can browse the files using the CM13 popup. But it doesn't seem to be mounted to the file system in a way that TB can find it (using detect -> whole device). I also can't find by using a 3rd party file manager to browse the system. I tried using stickmount. It complains about the SU that CM uses, and it never has the toast message whenever a driver is inserted, even though I set it to open stickmount by default whenever a USB drive is inserted. Installing all the apps I need will take up most of the file space, so I can't just copy over all of the TB backedup files.

Have you tried this:
http://forum.xda-developers.com/xposed/modules/mod-usb-marshmallow-1-0-t3272072 ?
That's for the phone showing up as a drive on a computer. I can get that to work. I was trying to get a USB drive connected directly to the phone over OTG and mounted in the filesystem. I finally gave up.

It also solved OTG mounting issues on my N7, that's why I suggested the module. Well, don't give up
How?
I'm on cm13 and I'm having the same problem with opening files and I installed what you recommended but I don't see any options when hooking up a USB drive over otg cable. I have been able to see the device in the included file manager enabling root but I seem to lose it and it's not helpful. What do I do? Thanks
Edit: it's definitely installed properly as it does remember my PC connection preference.
