tllim would be the one to answer that question.
As far as the first picture goes, that big blob of solder missed it's target... it was supposed to bond the microSD slot to the PCB via the copper pad... it obviously didn't take and latched onto the capacitor instead. My board has a similar 'defect' if you will as shown in the second picture around the RK808... one part is rotated, but in my case the capacitor it is bonded to on yours is missing. However, It doesn't seem to affect the board so far, so it may be a alignment glitch, or a last minute modification.
