I have a brand new SP4 i5 256 gb and noticed some strange things compared to my SP2 version. First, my Jaybird Blu Bud headphones connect to my SP4 fine, but the stereo connection never connects until I re-pair it. It always worked flawlessly with my SP2. Secondly, I installed Fallout 4 on my SP2 and it works great at low settings and never crashes. After installing it on my SP4, it works for about 5 minutes and keeps crashing. I really have not installed much on my brand new SP4, but surprised to see how poorly it works compared to my SP2 in terms of reliability. Can someone tell me if this sounds like a hardware issue or is this just a case in waiting for Microsoft to release updated fixes?
