[Q] Factory reset to some apps at fix permissions... Is possible?

[padre629]

Hi developers!

My phone since always, has (or had?) a little issue: the phone shuts down at taking a photo with flash.
(issue since having stock ROM until nowadays (vipers ROM)).

So, I tried the famous "Safe mode" (push volume down at startup)... all normal, the phone doesn't shuts down at taking a photo with flash.
Then I fixed permissions (through CWM recovery) (a trick that I've seen on the web, that improves performance)

Now my phone starts fastly (than before), but some apps performed an own "factory reset"
ergo, I open facebook and it opens like a fresh install!
Apps like: facebook, swiftkey, outlook and others that I don't remember.

My question is: ¿is normal that some apps perform an own factory reset at applying "fix permissions" and/or entering to safe mode?

I wouldn't advise 'Fix Permissions' if you've not done a clean install. The data directory has specific permissions.
A good example is a sense based ROM. If you run fix permissions on a sense ROM, you won't see contact images anymore.

You'll have to repair the permissions in /data, live with setting up the applications again or do a factory reset to avoid possible issues.
