I have my Nexus7 (Jellybean) for a couple of days now and love it.
Have learned a lot with the help of this great forum.
Have downloaded "Lookout" to hopefully stay ahead of any viruses, etc. . Also, have downloaded "Kingsof Office", which is amazing.
Now I'm wondering if I need some kind of "Defrag". If I uninstall and application, do I just drag it to the trash?
Before shutting the Nexus down, do I have to check (if so...how?) if any app. is still running. Is there a way to keep the OS optimized?
Again, I appreciate your advice very much!
