Gotchya you may want to invest in a new keyboard... Seems like caps lock was stuck.

I have swapped mine and still drop calls in all areas. The store i visit said they spoke to a samsung rep this morning and this is a known problem that is suppose to have a fix released sooner rather than later. Apparently verizon users had this same problem also but has been fixed. I think the call quality is also involved with this issue. I have tried the MJ4 update but still no fix.
