Issues
The Surface Pro 4 is known to have wide spread flicker issues with the display named as Flickergate after the independent websit
flickergate.comwhich was set up by the affected users after getting no fix from Microsoft.
Microsoft's spokesperson acknowledged the issue stating:
"We are aware that some customers have experienced a screen flicker on Surface Pro 4 and are monitoring the situation closely. Customers impacted by this should contact Microsoft support."
Microsoft has stated that bad batteries, pens and Type Covers may be repaired under warranty.
The Type Cover also has connectivity issues that afflict many, often due to a Windows update. This seems to be a common issue across the Surface series, with a sudden death to the Type Cover.

Reception
The Surface Pro 4 received generally positive reviews from technology critics. Most praise a sharper and larger display compared to the one found in the predecessor, redesigned cooling system, improved technical specifications, and an improved Type Cover. The common disadvantages found by reviewers were that the Type Cover is still a separate purchase, the relatively modest performance of the Intel Core m3 chip, and modest battery life.
