Veteran Note user here. Been on board with Note 2, Note 3 and Note 4. Have had the N4 like 10 days. Not a lot of difference between it and N3 but I still love the N4. Will find other difference I'm sure. Only one problem with the N4 that I did not have with the N2 or N3 and that is with the stock calculator. Seems that with the N4 when I hit a key on the calculator app I get a verbal response from the device. So when I touch the number 8 the device responds by saying "eight". Never had this with the other Notes and the S3 I had before them. Anyone else have this problem? Have to say it is a nuisance to have this happen when you use the calculator. I have gone to an aftermarket app from the playstore but I sure would like the stock calculator back working like it did with my other Notes. Any help getting this issue fixed would be appreciated.
