The numbers don't look too good for RIM and Motorola. ComScore's got the three month period ending in May 2012 numbers and Apple and Google posted minor increase month over month at 0.5 and 0.1 percent respectively.
Microsoft (consisting of Windows Phone and Windows Mobile) didn't budge between April and May. RIM dropped 0.2 percent over one month, but a 2.0 percent -- during the three-month period. Symbian also went through similar concerns, going down 0.2 percent month-over-month and 0.4 percent since February.
Apple added 1.5 percent to its customer base over the last three months for a total of 15 percent share. Samsung, still leading the pack in total market share at 25.7 percent, only grew by 0.1.
