Samsung Galaxy Note 5 appears in gold; your index finger will be used to pry out the S Pen
Another picture answers the question about how the S Pen will be removed from the phablet. There had been talk about an auto-eject method following a patent application made by Samsung. But that recently was shot down by anonymous sources in Korea. A picture allegedly showing the bottom of the phablet, reveals that there will be a small gap which will give you enough room to use your index finger to pry the accessory out. It looks like an auto-eject for the S Pen is at least a year away from happening.
The same photo shows that the Galaxy Note 5 will have the speaker grill, micro-USB port and 3.5mm earphone jack on the bottom, similar to where these are positioned on the Samsung Galaxy S6.
