Refurbished Samsung Galaxy Watch – check for compromise

I recently purchased a refurbished Samsung Galaxy Watch off Amazon through a third-party seller. Now, a few hours later, it occurs to me that it is possible that the previous owner could have rooted the device and that the refurbishing process did not undo it. I can’t just do a factory reset from the watch itself, since the owner could have modified the bootloader to only go through the motions of resetting, while keeping the compromise intact.

So,

  1. Is this something that I actually need to worry about?
  2. If so, then how can I check my new Galaxy Watch for compromised firmware? Is there an official process I can run, perhaps a reference firmware that I can compare to?
  3. If I find such firmware, is there a way to remove it? Alternatively, is there an external reset process I can do on the watch to ensure that no malware is left on the device, whether or not it is there?

Some miscellaneous information:

  • Primarily, I am concerned about the watch being used by a remote attacker to collect login credentials, such as for Samsung and Google accounts and potentially payment information (such as through Samsung Pay).
  • I do not have any reason to believe I could be specifically targeted – I imagine the device would be compromised as part of a random sample to get credentials.
  • I cannot get around using my Samsung account, since I plan on using the watch to track sleep and physical activity.
  • If I end up finding compromised firmware, or have no method of ensuring that my device is not compromised, I plan on returning the watch and buying a factory new one.

samsung galaxy a3: block all notifications except email and sms

Device: Samsung Duos (SM_A300H) Android version 5.0.2 

I want something very basic: that my samsung galaxy a3 works like a phone and makes sound only for call, sms and alarm. No more FB nor email nor whatever notifications.

I googled and found some answers that doesn’t suit my device. They say: Go to Settings -> Device -> Sound -> Default Notification Sound -> Silent. Next, set your text message sound to whatever you want.

I have Settings -> Sounds and Notifications, and there I can silent notifications, but there is zero options for message.

Smartphones are so smart that they aren’t phone anymore 🙁


This is what I see when I press sound button + options:

What do you know about Samsung Smart…

How to use Samsung Smart Switch to transfer data from iPhone to New Galaxy?

My Samsung Galaxy Note 8 Doesn’t Show an “Allow USB Debugging?” Prompt. Is there a fix?

Around this morning, I had the idea to transfer all my whatsapp chats(from android to ios)

Not so complicated, right?

Well, I was in for a rude awakening. Not only did I spend literally 7 hours trying to fix it… I couldn’t fix it!

That’s basically why I’m reaching out to you. My last hope. My knight in shining armor.

Here are the more technical details:

  • Before you say it, and I know you will, I’ll tell you – I restarted my phone about 10 million times
  • I’ve enabled and disabled usb debugging around 10 million times minus 1.
  • I haven’t played with adb so I don’t screw with my android system. However if that’s necessary, I’ll do what must be done.
  • I’m specifically using my own samsung galaxy note 8 since I previously tried on another phone(LG v20) and it didn’t work either.

So, I must ask you, are you up to this challenge? Can you fix what seems unfixable?

P.s. Here’s a preview of what should be showing up on my own android device but is not:

After Factory Reset, Android Galaxy Camera Touchscreen is unresponsive

I met the weirdest thing I ever have. I have a galaxy camera gc100, It works very well without any problems. Since I decide to lend it to my friend, I did a factory reset. After the factory reset, everything looks fine and the initial setup screen “Select language” appears. BUT, I can not touch anything on the screen. It seems that the touch is simply unresponsive at all until the screen turns off by timeout. And then I tried (1) hard reboot, (2) go to Maintenance boot mode by pressing power and zoom out and did delete cache and factory reset again. (3) flash stock rom. (4) take out of the battery and then holding pressing the power button for more than 1 minute and then insert the battery and boot. (did three times). But none of them works. This is just weird and I can not find anyone on the Internet having the same issue as me. Other people met unresponsive touch screen and then did hard reset to fix the issue. Mine is entirely opposite. I don’t have any problems, but factory/hard reset causing the touch screen is unresponsive at initial setup screen. Do anyone have any clue how I can workaround this issue? Thanks a lot. (Btw the system is still functioning because I can adjust volume and take screenshots by using the physical buttons).
