After 10 days of the SP4, I can't take it anymore. My Surface Pro 4 is a joke...even after doing the 11-2-15 update and I check multiple times a day for updates hoping for fixes. After 10 days, I can't even use it anymore. Outlook 2016 suddenly won't open after a sudden BSOD which happens frequently. Wireless range is not very good.... my wife's new Dell E7450 has great connection in the other room while my SP4 connection is almost non-existent and drops. I ended up buying a second Netgear R7000, both configured as access points in our house configured with the same SSID's, same passwords, different channels and my wife's laptop will switch automatically between the two AP's for the strongest signal....the SP4 just stays connected at 40 Mbps to the weakest AP...won't automatically switch. I guess that's what we get with the horrible and cheap Marvel wireless chipset. For MS flagship they should be using Intel. Light bleed at the bottom of the screen. Random popping sounds from the audio. I can't un-dock the SP4 and re-dock it with out rebooting because the screen flickers non-stop even after doing the 11-2-15 update. My touch screen suddenly stops responding so I attach my Type Cover, which I like, to finish my work so that I don't lose hours of research by manually rebooting right away. Our Surface Pro 3's had some issues when they came out, but this is HORRIBLE! I bought the SP4 to replace my office PC and SP3 and this thing is going back....it's junk. I tried, Microsoft failed.
