I installed this app after I received a notification on my lock screen informing me that a new system app was available for download. Seeing that the app was listed as an update to the "File Manager" app, I assumed it was safe and downloaded it. Now it's filling my lock screen with spammy looking notifications, prompting me to "boost" my phone to free disk space and memory.

The original File Manager app that shipped with my Android was very unobtrusive and was located in the Settings app on the phone. It never interfered with anything I was doing. It never sent me twice-daily notifications to 'clean my system', 'boost my phone' or 'free up RAM'. That is what makes me think this app is really malware posing as a true system app and tricking Android into installing it.

There is no way to uninstall it or disable it. The original File Manager app appeared alongside this app for a while, but the original app was recently removed and no longer shows up. My phone is lagging and other apps are crashing or not performing well since I installed this app. Additionally, this "Boost" app that has installed itself on my home screen is full of ads. No true Android system app has ever contained ads that I have seen, so this is very fishy. Also, the fact that it cannot be disabled is also very suspect.

I am suspicious that it is affecting my phone in a negative way and I want it gone! I cannot imagine that Android would release a "system app" that was full of ads. PLEASE HELP!

The device affected is an Alcatel Fierce 4 5056N running Android 6.0.1.

  • Did you root your device with some one-click tool, and/or connect to some random management tool on PC? – Andy Yan Sep 30 '17 at 1:23

    Yeah it looks like a Kingroot or Kingoroot root exploit was used on your device.... If you haven't rooted your device then somebody else had access to your device for enough time to install kingroot or a similar program !. it would only be logical to think that you may have a device infected with spyware at a system level. this can only be removed by flashing a fresh system img onto your device ! If i where you, I'd install kingroot and see if you can press unroot my device or similar.. This will at least stop the possibility to install any further spyware or malware, but not stop installed – Gadget Guru Sep 30 '17 at 2:17
  • Please add the exact package name of this application.. it would be easier to identify that way... Example com.example.app ... if you can navigate to the actual apk file in your system, you can extract it like a zip file... then open AndroidManifest and view the package name used ! – Gadget Guru Sep 30 '17 at 2:21
  • @Zillinium One cannot just unpack an APK and read the AndroidManifest.xml, as the .xml is encoded. – Death Mask Salesman Sep 30 '17 at 16:41

    Thank you to all who provided information to help me resolve this issue. The problem, as noted below by Rick Rademaker, was that this was a system app update from Alcatel. My system was not compromised in any way and I had not rooted my device. The device affected was an Alcatel 5056N running Android 6.0.1. I have edited my comment to reflect that @DeathMaskSalesman. – devdiva2017 May 15 '18 at 23:03

This is a system app update from Alcatel. Recently they started updating some of their apps. I haven't met anyone that thinks that their updates are very good. I'm assuming you have an idol 4 or 4s. I'm not sure why Alcatel started messing around with perfectly good apps but there are ways to get around it. Although you can't uninstall or even fully disable this app you can uninstall updates and stop automatic updates. Go to settings, apps, file manager. In the upper right hand corner push the three dots and click uninstall updates. Then go to Google play, your apps, click the file manager. Then in the right corner click the three dots. Uncheck automatic updates. This will keep it from updating. You can do this with all of Alcatel apps. IDK why they thought having a purple octopus in the main screen a good idea but myself and others have sent several emails regarding it and have been ignored. I'll never own another Alcatel again. I hope this helps, good luck! 😎

  • I did what Rick suggested and somehow its gone. I clicked on delete then not sure what I did next and the regular file manager came back and the the file manager with boost is gone. I do have my updates so they wont auto update. I am an older guy who is still learning about my phone.;-) – shipper Dec 12 '17 at 20:24
  • Thanks, Rick! This did the trick! I was able to get rid of that update and prevent it from installing any more. Thank you! – devdiva2017 May 15 '18 at 23:00
