Lumia 640 and 640 XL both have only 8GB phone memory

I used to have a 520 with a generic 8GB SD on it and it was auful: Live tiles of the apps installed in the SD card didn't refresh, apps themselves stopped working and I was forced to uninstall them...

Now I have a 830 with a Samsung Evo (Class 10, 64 GB) where I have installed games like Asphalt 8 with no issues whatsoever, not even launch times are affected, and life is beautiful again.

8gb is reasonable if you buy a good microSD. I used a transcend 32gb without problems in my 620.

Couldn't agree more!
