[Q] jpg thumbnails on android using explorer some yes some no - Android Q&A, Help & Troubleshooting

Hi, just been googling this problem 4 hours.
Device Nexus 7 2012 Android 4.3 rooted. The problem is: I copy a folder with 600+ jpg (some jpeg and png) files to device (pictures folder), gallery and all android apps show the pics ok and also thumbnails OK, but when I access via windows 7 or 8 explorer it shows some thumbnails and some not. (See attached capture please)
If I double clic in explorer all the files open in windows file viewer instead of in xnview 2.0.5 which is my default image viewer in windows.
Tried everything, deleted cache, deleted all images and gallery cache and copied them again, etc.
Its just some show thumbnails some dont!!
Any Ideas? Please Help?

File managers not copying files properly?

Hi guys
I've noticed that if I use apps like total commander or files by zenfield or any file manager by matter of fact and let's say cut/paste photos from gallery to different folder, go back to gallery photos are still in the same folder plus same photos in new folder.
It looks like photos are copied but the cache isn't.
However if I use built in file manager that is included with touchwiz ux all photos are moved properly.
Any ideas?

[Q] Images in internal memory not shown in Gallery

Hi. I have read a lot of post about media scan in i9300 and I cannot figure out what happens to me.
I have a folder of image , (for example whatsapp image) the folder was stored in the internal memory (mnt/sdcard/Whatsapp/media/whatsapp_image)
I copied some images to the folder from computer and my whatspp downloads the new image sent by my friends.
the most interesting thing is Gallery only shows the image downloaded by whatspp. The other images that I put into the folder from computer are missing.
I use "ASTRO File Manager" to see what happens. I found that the file manager cannot even generate the thumbnails of those image I copied from computer to the folder. It only have the thumbnails that downloaded by whatspp. (On the other words, only the image with thumbnails are shown in Gallery and they are downloaded by whatsapp)
But I can still open the image without thumbnails by pressing them and choosing "Use Gallery to open", It can be viewed perfectly. It proves the images are not damaged.
(P.S. If I use My Files, the stock file manager, all images have thumbnails. But the images are still missing, nothing changed or improved)
Then I use File Managers, (My Files, Stock File Manager, and ASTRO File Manager) to move the images without thumbnails to external sd cards (mnt/exSdCards/Temp). After that, ASTRO File Manager can find the folder and generate the thumbnails, Gallery can show the images after rescanning the media.
However, after I move the images back to internal memory (I even create a new folder under root of the internal memory), the thumbnails gone and gallery cannot show them after rescanning media.
Does anyone know what happened and how to solve it? I know I may use other Picture Viewer to "solve" this, but I hope to find out the real solution first. Thank you.
Sorry my thread are too long and my english is poor.
I may post some screenshots later if you want.

[Q]All gallery files disappeared

Suddenly all my pictures and videos disappeared.All Viber, Whats app, Screenshots, camera, downloaded - everything... Only new ones I take are showing. The files are missing in the folders too. I have two DCIM folders - one on internal and another on external drive but they are empty now. I tried File Explorer, ES File Explorer with "show hidden files", and I've checked all of the device folders, but I can not find any of my pictures or videos. I tryed with QuickPic - same sh**... If i connect my device to my PC the result is the same. The PC recovery soft which I test, found about 3000 files, and with all emoticons and trash there were my pictures but in very low res. So I tried Hexamob Recovery Pro (from the Play store), but the result was the same - about 12 000 junk files and some of mine in low res... The method with deleting all .nomedia files doesn't work. Than I've installed Undelete - This app found about 300 files, and these were all of the missing files, but when I tried to restore them, It asked for a license key... The free version could restore only pics...one by one... You can't select all!!!
So how to restore all my stuff without stupid apps!?
*my camera freezes often. "Could not connect the camera" appeares, and I need to reboot to solve this prob
Samsung GT-I9300
Android Version 4.1.2
Baseband I9300UELK1
Kernel 3.0.31 -Siyah-1.8.6+
AOKP Milestone -1 Jelly Bean
Omega v4.2
Where are these files stored (hidden), what is there extension? And why only Undelete can find the proper files with their full resolution!?
So, I found that Undelete detects files at DCIM\DCIM\Camera, but even with "show hidden " explorers does not see the second DCIM folder... Any suggestions !?
You can try
http://android-photo-recovery.com/tutorials/recover-deleted-photos-from-samsung-galaxy-s3.html
Or buy the Undelete licence .
Or read the multiple identical lost photos / files posts .

Thanks!
But I already checked similar posts, and stil can't find solution .. The soft that you recommended, resulting small images too.. The idea is not only to recover, but to prevent future problems of this kind.. I want to understand what causes that

[Q&A] How to Share Facebook videos w/o Apps

Hi there,
I made a quick search about this, but I wasn't able to find a complete answer.
Just wanted to share how to view/share/save Facebook videos to other apps (i.e. whatsapp).
The reason why I prefer doing this over using an app, is because some "video downloading" apps require you to login inside their app, and for me that doesn't seem safe.
Requirements
Facebook App
Root Explorer (or similar)
Rooted phone
Procedure
Open your Facebook App, and watch completely the video (or wait till it finishes loading).
Use Root Explorer to go to (Bookmarking this makes it much easier):
Code:
data/data/com.facebook.katana/files/video-cache
Arrange the folders according to Date (so the latest date/time is the video you just saw).
Copy the file inside the folder (i.e. 00000000), to a safe folder back in your SD or extSD
Rename the "0000000" file, to whatever name you like and using the extension .mp4 (i.e. video.mp4)
Watch or share the video from root explorer (long-press and share)
Notes
I believe is safe to delete the whole cache folder to work better
I have only used the .mp4 format and it has been effective so far
You can't watch the video inside the Cache folder (at least w/my phone)

.nomedia folder doesn't show any pictures - says "no files" in the folder

Hi android community,
I bought recently a Motorola Moto G (2015). I wanted to hide some pictures from being seen when I'm scrolling through the phone - so I created a new folder ".nomedia" and switched about 30 pictures into this new folder. It worked great - my gallery didn't show these pictures anymore. Unfortunately it worked too great. I removed the "." to make the pictures visible again, but there are no pictures. I renamed the folder again into just "NewAlbum" - still no pictures. I browsed with the ES file manager to the directory, but the folder is empty. It says there are no files . Could it be that my 30 pictures are just deleted like this?! Can I make them visible again?
I also took out the SD-card and put it in again - no effect
So basically my problem is - the folder is still there, I can see it. But it is empty
Is there any possibility to got my pictures back?
My device is Motorola Moto G3 (2015), Android 6.0.1
