My Note 4 is experiencing the same extreme lag issues and freezing that everyone else is describing. Take a photo, screen will sometimes go dark and phone is frozen. Receive a text, phone sometimes freezes and goes dark. Swipe to answer a call might work, or it might not. Back button might work, it might not. Take a video in landscape, it only plays back in portrait. Try to open Google Voice, maybe it opens, maybe not. Screen stays on during a phone call and changes to whatever screen it wants to while I'm on my call... bleeping and blurping the whole time. And last night, not even using the phone, it froze and went dark. I primarily use business productivity apps. Phone has had two factory resets since purchased in July. I restart it all the time. I pull the battery. I've cleared the cache repeatedly. I've sacrificed 3rd part apps hoping to make thing better. Battery life is poor, despite the reviews raving about amazing battery life. These issues are probably not all related but I don't care... and I don't care why these issues happen. All I know is they aren't my fault and for $700 we all deserve a heck of a lot better. I have been a loyal Android user since the original Moto Droid but the neglect of either the hardware quality control or the software on this Samsung/Verizon phone has me considering an alternative to being embarrassed to use my Note 4 in my client's presence. "No updates are available. Your software is up to date." Sure.
