Ok,s so I decided not to to use a task killer app to end running tasks to free up space on the phone, instead im going to use the built in 2.2 feature. Now, my question is when I go into this from setting and manage application, I notice a few weird things named: com.android.provider.applications, com.android.provider.userdictionary, PVWmdrmService, and PVMtpServiceStar. What are these things and are they cool to keep going? Also, if I want a app to stop working, do I do Fore stop? Is this even necessary? Also, I noticed that my auto rotate has been acting up. Like, its not doing it alot of times. Im worried that my Phone got a virus or something, can anyone help eliviate my worrys?
