So yeah, a couple of apps gave me the Error 505. It doesn't matter what I do, I can't install them on my phone or tablet. Both are running their latest software respectively, which is 6.0.1.

I did EVERYTHING from clearing cache to hard resetting. Any help would be appreciated.

Thanks.

When you say hard reset do you mean factory reset? Did you have those same apps previously installed in your phone? Which apps are giving you problems? Usually this error could mean different things.

- The app isn't compatible with your system version.
- There are still some files of the app in your phone after an incomplete uninstalling.
- They are still active in a guest account.
- Also, check you've got the right date and time.

Another thought. Do you have any app installed created by the same devs that the ones giving you that error?
