Openning the default texting app takes 3-4 seconds. Sending a simple text message lags after hitting enter. Typing in text sometimes lags too. I've also noticed lag in other apps but the most noticeable is the texting app. I have default Android 4.2 - not rooted. No special apps. Just normal apps. What gives? It wasn't this slow before. Makes me hate Android. It's almost as slow as my 6 year old iPhone 3G.
