[Samsung Galaxy S7 Edge Questions and Answers] SCutshall:
Hi everyone,

Long time iPhone user who finally made the switch (first iPhone in 2007 all the way through iPhone 6 last year but wanted to try a new platform -- plus was getting very tired of the cookie cutter'ness of iOS).

I've had my Galaxy S7 Edge for a week now and couldn't be happier.

However I have experienced an issue (that I resolved) and would like some thoughts & opinions from those of you with far more Android & Samsung Galaxy experience than I have.

Okay, I'll outline exactly what happened...

1. Been shooting a video nightly (for a FB awareness project) with zero problems but the other day my micro SD card arrived (SanDisk Ultra 200gig Micro SD XC I) and after installing it (no issues, phone booted perfectly, found the card, all was well) I shot that evening's video. However when I went to play it back before uploading it to FB the video played for the 30 seconds and I got a pop-up window saying "Unknown Error, try Again". So I did, and each time I tried playing it the same thing would happen... 30 seconds in, error window, rinse/repeat. So I deleted the video and reshot a new video. On this video, it would play for 3 seconds and I'd get a pop-up with, "Incorrect Data Try Again"... tried playing this new video a few more times before deleting it and starting over.

**worth mentioning: on both of the videos I also opened up my stock Samsung video editor, and using the slider for trimming videos I was able to move the slider past the 30 second mark on the first video, and past the 3 second mark on the 2nd video, and then both played fine (within the video editing feature only~~I tried playing them both outside the editor again and they wouldn't: #1 up to just 30 seconds and #2 just to 3 seconds--precisely like before**

I rebooted my phone and then shot yet another video, it played fine and uploaded onto FB perfectly.

So, does anyone have any ideas? I searched around Google and found many posts regarding camera issues on the S7 but nothing regarding video playback errors.

Could it have been my SD card?

Which now leads to question two...

2. A bit later that same evening I read an article and watched a couple YouTube videos on copying/transferring photos from the S7 internal drive to an external... so I successfully did that with some photos as well as creating a couple folders on the SD card as well.

I then read and watched some other articles and videos on moving apps from the internal to external drive.

Following the tutorials I noticed some apps had the option to be relocated while some did not. Two that I thought would be good to relocate were Facebook and Facebook Messenger (I looked in my Storage screen and after everything populated I noted that those two apps were using more space than any other app so I thought I'd relocate them).

They both relocated fine, the screen showed them both as now located on the external drive.

I closed out of Settings and then went to my desktop and clicked on my FB icon, the screen froze, and then the phone began to reboot.

For the next 20 minutes my phone stayed in Boot Loop and either would reboot to a black screen or my lock screen with the time & date as well as a message at the bottom of the screen showing I was connected to my home wifi and then lock up and reboot again.

Using my laptop I Googled how to fully shutdown my phone. I restarted/shutdown the phone a few more times--all resulting in endless Boot Loops before powering down and popping the tray and removing the SD card... was then VERY relieved, upon putting the tray back in with just my SIM card & powering back up, to see that the phone restarted beautifully.

FB & Messenger were missing from my phone's desktop (that seemed understandable) as well as some photos that I didn't copy but had instead transferred (understandable as well).

I took the SD card and put it into an adapter and plugged all that into my laptop to see what was on the SD card..

A very large folder labeled Android, another labeled LOST.DIR and two that I had created for my photos.

So has anyone else experienced this? If my SD card was bad wouldn't the phone have not read it or not been able to store data on it? Also, if the card was bad why can my laptop find and read it?

In the end I copied the two photo folders onto my laptop (interesting to note: one of the two photo folders that I created on my S7 couldn't for the most part be copied to my laptop because most of the photos were corrupted in that folder--however, they had all been viewable on my S7 earlier that day... and yes, these same photos were transferred over from my iPhone a few days earlier at the Verizon store) while I deleted the Android & LOST.D IR folders off the SD card... I am debating between the following actions:

A. Returning the SD card for another new one.

B. Putting the SD card back into my S7 now that it's been cleared of all the folders and see what happens.

C. Putting the SD back into my S7, formatting it, and then putting some photos & videos on it to see what happens.

In all events I am seriously leaning toward not ever putting apps on this or any SD card in my phone after what occurred--thoughts on that?

Any help, input or explanations would be greatly appreciated.

Thanks for reading all this (sorry it's so long but I wanted to include as much info as possible)...
