great we have diversity in apps and can use them daily

Can you please tell me how you got rid of that lock out app? I am having same problem you were and apk wont load.

Can download apk file but wont install. Phone s onays it cant scan file then crashes. Another person said they had same problem and they found a pre installed lock out app on their phone they had to unlock then the apk installed. Can anybody tell me how to find that app on my phone and unlock it. Thanks

I recently had the same problem as above. I could not find a way to completely turn off the "Lookout" app on my phone; therefore, I temporally uninstalled the program. See my directions below.

Find the steps below to allow the "APK" file to open.

1. Temporarily uninstall the "Lookout Security & Antivirus" App on your device.

Settings>Phone (Applications) [The "Applications" option should have an orange icon]>Applications Manager>Find "Lookout" in the alphabetized list and click on it> click "Uninstall"

2. Download and open the "APK" file

3. Reinstall the "Lookout" app

I hope this helps!

Ok im with you on the down load problem on the fox fi key . My phone also scans then says cannot scan. Ive done all you have said except the last option . I cant seem to locate the orange icon to get me access to uninstall lookout. Im either not reading it right or my brain us fried. Its very simple from what you have written. Can you see how i might be missing this?
Tj

I had the same problem, and since Lookout comes pre-installed I was not able to uninstall it...but I was able to turn off "App Security" under Settings and worked like magic. I hope this helps.

How U do tht?? I'm having trouble also

Open Lookout, go to settings, make sure you un-check 'App Security'

See the screenshots. Sorry they are so big.

Don't worry all you have to do is reset and let ur phone delete everything because it has virusus

you may need to reset you phone system or you can read more here

Can u tell me where u found lookout? I'm having the same problem.

You would think, that if we authorize an app to be downloaded that would tell the security systems to stop shutting down the apps we install.. so annoying..

Lookout was the problem for me. Even though I force stopped the app, turned off everything that was said here. It finally worked once I took off Lookout as a default for other apps. Went to install the apk and it asked me the choices of how I want to install it. So it's because Lookout is set to default .

I have the same problem but I don't have lookout

You posted 2 yrs ago lol but I will answer it because someone else surely will have the same problem. All you will need to do is disable lookout security.

Glad you got the problem fixed!
Just one question,
The apk you were trying to install!
I'll bet that it was not a Google app!
Lookout is a Google security app. And Google probably programmed it to reject any apps but theirs!
Just another one of Google's underhanded business tactics!
I used to have lookout in my phone, untill i discovered that Google uses lookout as a back door to install unwanted updates and bloatware apps in our devices!
That's when I uninstalled lookout permanently!
Fortunately lookout was not factory installed app in my phone so I was able to get rid of it all together!
