Yes everyone now uses a smartphone but let me give an instance when I was doing my project field work I was working on farmers and the level of access to financial services and investment level and productivity pattern. I noticed something that baffled me some of them most of them cannot read and don't use smart phones a good number of them communicate through their children (who are educated or still in school) some of them are not willing to change to better ideas proposed by extension agents they prefer the crude and old method of farming which is not good and suitable for large scale production.
This is a general attribute of farmers in Africa and in particular Nigeria. But I know that with time and with proper senstization as long as the right things are put in place that there will be improvements.
