Hackers

I'm not good with computers but I believe my android phone got hacked just recently. What damage can I expect if clicking on a videolink in fb that is planted by a hacker?
Do I need to do a factory re-installation of my entire phone in order to get rid of this evil?
If so - how do I save the following in such a way that it can be re-installed later the same way it is now?
- My google calendar posts
- My saved bookmarks

Is there some way to see/screen if my phone really is hacked?

 

Hello,

What phone model are we talking about, and what makes you think your phone got hacked?

 

It is unlikely that your phone is hacked, but it is always good to check if your data got a backup in case you need to reset your phone, if it breaks or get lost.

The Google Calendar app should be synched to Google Calendar. Browse to https://calendar.google.com and check that everything is synched. Also check that everything is synching on your phone. Settings->Accounts->Google and then click your Google account.
If you are using Chrome and are logged in then your bookmarks should also be synched. Open Chrome on a computer and see if your bookmarks are there.

If it is synched then you just have to login with your Google account to restore everything after a reset.
