I have a Lumia 640 XL that is beginning to show its age plus it will be no longer supported. I have to use an iPhone for work and I try to use Cortana but the functionality is very limited. I asked her to set up a timer for example and it opens a web page. I'm not sure if its an Apple thing that does not allow Cortana to function fully or what, but it is a frustrating experience to say the least. Can some one tell me if Cortana on Android is any better? I will need a new phone within 6 months to a year. I love and use Cortana for everything on my phone from setting reminders, appointments, everything. Thank you
