My wife and I both Have Galaxy S5s, and have loved them. However, once the lollipop update installed both phones are extremely laggy, practically unresponsive and almost unusable. apps take forever to open. it takes longer to switch between the two, typing is delaved by several secconds. it's like the HTC G1 all over again. I've never wanted an iphone so much in my life. I'm assuming I'm not the only one? Is there NOTHING I can do about my phone before I want to throw it against the wall?
