In Device Maintenance system app on Samsung Galaxy Note8, there is a TopBuzz cache shown when caches are being cleaned. Also in the safe mode. It reappears as a cleanup item every few minutes together with System cache item and they show 82 MB to clean up.

enter image description here

Since nothing like that is installed, I originally thought this is a sign of a malware, but after rebooting to the safe mode, the behavior continues and both items are re-appearing every few minutes in 82 MB size.

Is TopBuzz normal part of Note8 built-in software or is it possible that it somehow got into the phone later? How can I determine what is happening here?

Additional details:

  • The phone is not rooted.
  • Android 8.0.0.
  • 5 anti-virus scanners did not find any issue with TopBuzz.
  • I reviewed the entire app list in the safe mode and found nothing like that.
  • Despite the name on the above screenshot, I did not find a public or hidden cache called TopBuzz using SD Maid app. Any other caches shown by SD Maid contain only few kilobytes after cleanup, 82 MB is nowhere to be found. But TopBuzz + System cache still show that 82 MB size in Device Maintenance app.

Update: Samsung support replied me that "TopBuzz is not a part of their device".

    No idea, but here's the app on Playstore. If you're familiar with ADB, you could use that to check whether it's installed (like adb shell 'pm list packages'|grep ss.android). – Izzy Jan 8 at 22:52
  • Please, if someone else with Note8 sees this, kindly drop a note here. – miroxlav Jan 9 at 8:50
  • Search for "buzz" in SD Maid's AppControl, make sure you have system apps included via settings. It will search both app names and packagenames. Could possibly be an instant app which shows almost no where... – darken Jan 11 at 8:47
  • Yeah, so I downloaded topBuzz when you are looking try to look for something like com.ss.android.article.master or anything starting with com.ss.android.article. The app has a very high amount of permission request at about 48. – Bo Lawson Jan 11 at 18:59

I have a Samsung Galaxy S8 and have the same problem as you with TopBuzz showing up in the storage clean but unable to find it anywhere in my phone.

I tried the SD Maid app but that did not help. However, I did try Clean Master which I have used in the past with my old phones becuse it does work better than the built in storage clean (but uninstall it when im done with it because im sure that it slows down the phone to make you use it from time to time) and that appears to have fixed the problem.

I ran Clean Master, then ran the system storage clean and did not see TopBuzz, ran Clean Master again for good measure and then uninstalled it. It has only been a few hours but I have ran the storage clean a couple times and have not seen TopBuzz at all. If you still have this problem try this out and let me know how it goes!

  • I am glad to accept this as an answer because it seems that it worked for me. Installed, cleaned (without anything reported), uninstalled and the Topbuzz seems to be gone. Thank you. – miroxlav Mar 24 at 20:38

Samsung support has replied me that "TopBuzz is not a part of their device".
So this is most likely a sign of an utilized exploit where a malware can compromise even non-rooted device.

  • If you are keen on identifying the package name and app name for TopBuzz, can you give the output of adb shell cmd package list packages -f -i -U? Use a code paste service such as Pastebin to share the output. That TopBuzz is either a malware itself or is installed by a malware. See google.com/… – Firelord Jan 28 at 21:51
  • @Firelord – thank you. I am new to Android. I must once sit down and put my hands on adb shell. Currently, I am acting only as "ordinary user". :) – miroxlav Jan 29 at 0:26
  • Oh yeah. I'm sorry I missed that you are new to Android. Please take your time and get acquainted with adb, if you are keen on digging into this further. I cannot promise that I would be able to find the culprit but I can offer my assistance. :) – Firelord Jan 29 at 0:28
