I haven't had an android phone in over two years. That phone was the Samsung Galaxy Epic 4G. Then I switched to the iPhone 4S. The reason I switched was that I found the Epic to lag a lot after only 6 months of having the phone. I also had a ton of force closes. My question is, will these newer android phones, specifically the Note 2 as I am interested in buying one, begin to lag after 6 months of use? I would love to come back to android but only if I had a lag free experience. I don't want to have to root my phone in order to get it to work either.
