Hey guys, as you may know, china phones sometimes get shipped with spyware or malware.


I found backdoor in the TripAdvisor APK.


Anyway you should scan your phone with G-Data (you can download it in the google play store for free)


On my HDC S5 and EFOX E5 , there was a tripadvisor APK which has an android backdoor in it.


Not sure if falsepositive or not, but lets remove this shit.


I couldnt uninstall it the normal way in settings. So i tried the root file manager to delete the APK in /system/app  but it cant be deleted !! EVEN WITH ROOT !


Ok now lets go the hard way and lets remove it with the terminal emulator :


1. Download the emulator from the google playstore and make sure your phone is ROOTED !


https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=de


now follow the commands :

  1. su (root Login)
  2. mount -o remount,rw -t rfs /dev/stl5 /system
  3. rm -r /system/app/TripAdvisor.apk  


  4. mount -o remount,ro -t rfs /dev/stl5 /system


This was just for the tripadvisor apk. If a different APK is infected , replace the name !

Also dont forget to uninstall all china apps from your phone. We also have a tutorial on that in the tutorial section



Hope your phone is safe now. Enjoy!

Thanks very much, I'm sure this is going to be useful in the future and I'm going to make sure I scan my new phone when I order it.

Also you can use titanium or other thungs to get rid of it



but for me it didnt work even with root explorer, so i had to use the terminal

Or more simple: use NoBloat Free (install it from Play Store).


If a system app was updated, you have to uninstall all the update to restore the original app. So you can see it again in Nobloat Free.


You can disable apps, or delete it with a backup. So you can restore all if something goes wrong
