Previously posted this in general cell phone discussion, just realised that was probably the wrong place. Thanks in advance for any help!

Left my Samsung S7 alone for a short while last night. It had an os update pending but I hadn't told it when to do it.

Picked my phone up after half an hour or so, had been receiving whatsapp messages in the meantime (had web whatsapp open in my laptop). When I picked the phone up it was the get started screen you get when the phone's new - my first assumption was it had just done the update on its own... but it needed me to enter my wifi password and go through setup. It eventually recovered most of my stuff from the cloud but it lost all my sign ins and bank app verifications so took hours to bring it close to where it was. It also wiped all my Google authenticator data so on some sites I now have to wait a couple weeks to re-verify who I am and email them photo ID & etc... Massive p.i.t.a.

But worse than that... I seem to have lost all my SD card data including most of my photos and all my music? Why/how would that happen?

Oh and to top it off, it still had the update pending once I'd gone through all this kerfuffle.

I'm sort of resigned to having lost some data, but I want to make sure this is a 1 off and not the beginning of the end of my phone. I've had it two years but recently paid to replace the battery and the screen so was going to sell my upgrade phone and keep this running for a while, but I never want to have to deal with this BS again.

It sounds like it wasn't an update but a wipe of the device and card. An update won't wipe your data. Now a "Hard Reset" that can. But you have to take steps to do that. Turn off the device, hit certain buttons when turning it on, etc. So it makes me wonder if there was/is something on the device that caused it. Bad app, malware, virus, etc. I would scan for these.

Also, try restarting the phone. This may make the data on the SD card show again. If not, while there is no guaranty that you can get them back. Deleted does mean deleted. There are a few apps/programs out there that 'may' be able to help you recover the data.

A few of the programs you could try would be... DiskDigger, MobiSaver, Android-Recovery and Tenorshare. They are all data recovery apps/programs. There are many others out there, so check around and see which you would rather try. There is also one called RECUVA, that I have heard is free, which you could try.

One important note though, most of these programs are not free. They may say they are "free" or have "Free Trials" and "Free Downloads". Yet to actually recover your data, and get your files back, you may be have to purchase the program/app. Just so you know.

NOTE: For future reference, I really would suggest backing up your data to a computer or cloud. Often. Better to spend the time doing that, rather than to be out all that stuff if the phone dies, things get deleted/erased or it gets stolen.

This EXACT thing just happened to me yesterday (09/06/18). Used my phone in the morning, went on a walk with the dog came home got ready for work, turned on the phone and it was on a white screen, in vietnamese with the "START" logo. I was obviously confused, so I changed it to English and proceeded. It complete did a factory reset on the phone AND come to find out wiped away ALL the data on my SDCARD. I am beyond angry.

Has anyone else seen this issue? Is it malware? Hacked? I'm so confused.

This just happened to me on the 8th or 9th of September 2018. My phone's a GS9+. It asked me to update and it ended up by doing a factory reset.

Happened to me tonight. I took a call & went to the store. While in the store I opened my phone case and it had a black screen and said I needed to factory reset my phone. For the past 2 days it's been shutting off by itself as well. Oh and then my phone was saying it wasn't compatible to any if my chargers. Hoping it fixes itself over night tonight. I love my J7 & don't wanna have to get another phone.

Just happened to my wife galaxy s7 today, 9/26. Everything gone, she said she saw the android, and next thing it said erasing .....
Then she got the start button. It had been restarting, or shutting off if you just even as much bumped it, alot lately on her. Mine went through that phase for a while then seemed to just stop. I also had the issue of not charging, i would remove the battery and turn it off then it would charge

Hey guys, nothing was deleted and don't download any apps for recovery.....

I was just having the same problem. I thought it was all erased too. But open up settings/device maintenance/storage/sd card (it's at the very bottom). I found everything still there. Looks like the update made it to where the phone isn't reading from the sd card, only system memory, making you think it's deleted. Hope this helps.

Just happened to me last night! Everything wiped away -- photos, contact info, texts, everything. So upset. Phone was fine. Picked it up later and I saw the Android symbol saying "erasing". There was nothing I could do to stop it. Then a new start up began. So, so frustrating. I'm going to go to the cell provider today to see if they know how to fix this, probably not though. :(

It´s interesting that i found this post.

I had a similar problem in may/2018 with my S7 Edge (G935F) running Nougat. All my data in the SD card vanished, but the phone did not factory reset.
A few days later the started restarting out of nowhere. Sometimes it kept like a week on, sometimes it restarted like 10 times a day.

Sometimes it got incredibly hot, sometimes it restarted and felt cold.

I tried wiping cache, factory reset, using odin to flash the stock rom again, used Odin and changed to Oreo... the problem persisted.

I just let this phone in a drawer and bought another one. A few weeks back i tried do get it working again after reading that this could be a battery issue. I bought a new battery and the problem is still here.

A tried cleaning the oreo using ADB removing all the bloatware from Android and Samsung... it was not sucessful either.....

My S7 just did the same thing Last Friday. I did an update the day before. Phone was fine and then it just went to a white screen and said something like wiping or resetting. All I was able to get back was the picture on my home screen. Samsung was USELESS when I called them. Verizon was able to get some stuff off the cloud. I have been very disappointed with Samsung lately. Updates just keep messing up the phone. The good new was my contract renewed the same day this happened and I went and got an Iphone. After being loyal to my samsung phone for years I say good riddance. Back up your phones people!!
