In reply to Mahabub. Please how do I go about this? I use a Hauwei y6 pro. I'm trying to download the WPS + PDF app. How do I find out the apps that are from the same developer or have same certificates? Thank you

Here it is. I have got the final solution. These developers are using same certificates for all of their apps. so you can not install 2nd app from the same developer if u have an app already installed from the same developer. Just uninstall the previous app and there u go. Now u can install ur desired app, just only one from the same developer.

Excuse me I know the perfect cause why this error505 occurs. Let me explain. I have downloaded gangster vegas which is a Gameloft game and later I tried to download six guns then this annoying thing showed up. This is because both the packages have the same name ie., Com.gamloft.GNMP or something else. So to avoid this you need to move one app to sd card so the package also transfers. If the error perror persists again it means there may be junk folder in Android/obb. If you delete it then everything thing will be fine.
Thanking you
If you want further help please reply.

NONE OF THE ABOVE: had both MS Word & Messenger working just fine in Lolipop 5.1 untill it says they have to update. Then 505 error, and, Icon disappeared, so It really has nothing to do with resetting or fac update
I’ve been using Messenger & Word right up until this bad update. Has nothing to do with Lolipop, if it did I wouldn’t have been using Messenger this past year. It’s these constant unnecessary updates by poor coders wanting to change something that’s not broke, that’s the problem. #Dumb

In reply to Beverly Glover. My Dad just came to me and said that every time i try to re-install Facebook (after uninstalling it due to the fact it wouldn't update or open the app) it downloads the app the app from the play store and gets so far into installing it and then says ERROR -505 cant install the app any ideas on a way round it ?
