Samsung Galaxy S9 Plus not recognized by Win 10
- Hi,
I am really sorry for the length of my post. But your help is highly appreciated.
I do not know if the described problem has to do with this issue. My Phone fell down into water about a year ago. Only the bottom has been in water,
not the whole phone. Then there have been some problems. It didn't startup properly etc. Now it seems to work again. I have not tested everything.
An unofficial service shop has tested a bit and says that there is no problem.
(By the way, they said they tested also the microphone. I did not gave them the telephone code. How is that possible?)
Now, and since months my Phone Samsung Galaxy S9 Plus (SM-G965F) is not recognized anymore when I connect it via USB cable with my Notebook, Lenovo Windows 10, x64.
I have installed the latest version of Smart Switch. But even without Smart Switch there is an error message in Windows (translated from German):
"USB device was not recognized.
At this moment I am also downloading the latest version of Android.
The last USB device, that was connected to this computer did not properly work and is not recognized by Windows.
Windows Explorer"
I strongly assume that the cable is original. I have not found any other.
Another (not original cable) is not even recognized with an error message.
But nevertheless, I think I will buy a new original cable.
I have followed the instructions and enabled the Developer Mode on Android, and MTP is enabled, BUT it is not shown in the top menu bar on Home screen (when you scroll it downwards):

- Hi,
i have tried, none worked.
I also tried under Linux Mint. The Phone is not recognized but charged. Now i have learned that there are two connector one for charging and one for data transfer.
So a change of the usb connector at the phone would lead to success recognizing the phone under Windows? Or could there be another factor for the error? Just wanted to know that in advance.12-29-2019 03:38 AMLike 0 - Hi,

Just to double check you, have you choosen the appropriate selection from the notification, of connecting phone to computer, in the status bar?Laura Knotek likes this.12-29-2019 10:23 AMLike 1 - Hi,

The shop did not repair, they only tested, they said.
Other questions:
1) I don't want to be paranoid but afterwards I have remembered that I had sensible/important data on that phone. I did not giv them the phone code to get access from the locked screen to my phone. I did not gave the service shop any code. Bitdefender has mentioned that there was failed access attempt to my phone, to get access to it. It took a picture. I have configured it for that.
My question is: Could the workers of the phone service shop get any kind of access, e.g. by cracking my phone or just trying. I mean, they are professionals or semi-professionals. My phone code consists just of four digits. There was no SIM-card inside the phone.
2) When I took my phone back the date was set to january 1st. Why that? How can that be? It was charged full there because I could not charge at home. Did they remove the battery and set it back?
I appreciate you help and want to apologize for my noobie questions. Sorry!mustang7757 likes this.12-29-2019 11:01 AMLike 1 - I dont believe they could get into your phone , because they would have to allow access prompts to connect to their computer and to do that you need to get into the phone to allow it .
I'm not sure how the date changed possible without the sim in it . No repair shop will work on a phone without you factory reset or you unlocking it and watching them look at the issue in front of you .12-29-2019 11:11 AMLike 0 - Hi again mustang and all others,
- i tried Safe Mode on my Samsung phone on my notebook: No success. Charging but not recognizing fpr data transfer.
- another notebook, my Samsung normal mode and in Safe mode: no success again. the same
edit: How can they test the microphone and other units (as they said) if it is working properly, without access to my phone?
Thank you all for your patience.12-29-2019 11:25 AMLike 0 - 12-29-2019 11:27 AMLike 0

I am not able to backup at the moment (via cable). Can you tell me any good program for windows so that I can send all my important files to my notebook securely? E.g. via WiFi.12-29-2019 11:51 AMLike 0 -
I would use Samsung cloud if your not sign in to back up everything as well as Google photos.12-29-2019 11:53 AMLike 0 -

What if I dont't want to use Samsung Cloud or Google Photos?
Isn't there any secure software for connection (e.g. over WiFi) from my phone to my notebook?12-29-2019 11:56 AMLike 0 - Not that I'm aware of , maybe other members can chime in but I have lot of Samsung devices and had zero issues doing through cloud or google photos security wise or losing information .12-29-2019 12:01 PMLike 0

- 1. The shop could have gotten into your phone without your password.
2. There are charging contacts on the USB connector, and there are data contacts. The data contacts could be bad (or not connected or anything making the computer not see the phone) while the phone still charges. (I'd say that you need the USB port replaced.)
3. There's WiFi File Transfer among many others.12-29-2019 05:10 PMLike 0 - Hi and thank you. I don't want to get on your nerves but:
- How is that possible and
- Can i see in any way (log etc) if there has been access to my phone?
Thank you all.
edit:
- i need to extraxt and/or backup the Notes in Samsung Notes i made. Where are they stored and how can I get them?
- I have had used the secure folder. There are also Samsung Notes. How can I get them? And how can i get my contacts in that secure folder?12-30-2019 03:13 AMLike 0 -

Contacts (if you did things correctly - created them as Google contacts and had Contact Sync enabled) should be at Google Contacts. When you add that Google account to another phone, it will sync them to that phone. Getting them directly from the phone requires that you export them from the Contacts app, then copy the exported file to another device.pizza_pablo likes this.12-30-2019 03:26 PMLike 1 -
Thx again.

I wish you a happy new year in advance.12-31-2019 10:19 AMLike 0 - Hi,
first of all I want to thank you all for your patience and help. I know that patience is needed to help people from all over the world via internet.
Sorry for my late reply here.
I would like to ask a few more questions.
I gave my phone now to a second phone shop and now it works. My Samsung is recognized by Windows, it charges. I will ask the shop again if they replaced the USB connector. I forgot.
But as a paranoid I have some mor questions, I am sorry for that in front of you normal people ;-)
- When I took my phone back (from the first phone shop) the date was set to january 1st. Why that? How can that be? It was charged full there because I could not charge at home. Did they remove the battery and set it back?
- Could the error (that I described in my first post, no recognition of the phone in Windows etc) have been eliminated when I did a hard reset of the phone?
I dont believe they could get into your phone , because they would have to allow access prompts to connect to their computer and to do that you need to get into the phone to allow it .
I'm not sure how the date changed possible without the sim in it . No repair shop will work on a phone without you factory reset or you unlocking it and watching them look at the issue in front of you .
I do not want to know how, I just want to know if possible and how the chance/probability is, for each scenario.
1.) Is access to my phone without the knowledge of my passwords possible or not?
2.) Is it possible that they found out or cracked my codes for gaining access?
3.) After a bit of investigation I found out that there is software to rescue data both from ios and android systems (For example: Dr. Fone). Maybe with software like that?
4.) Let's assume, my usb connector for data transfer was damaged. Could the shop have gained any access to my phone, e.g. via wireless connection (WiFi,...)? Does Dr. Fone or an Alternative work without usb cable connection?
5.) Is there any other way I forgot?
I am really sorry for that kind of questions, really, by heart.
Your reply is appreciated.
