I have only 2 apps installed: Facebook and Whatsapp, where Whatsapp not also running so smoothly.
I really have not had for the price too high expectations. I just wanted a basic model for my mother, who with smartphones (still) knows not so good - there is really OK, where you also noticed how slow the unit is operating.
If you want to test whether smartphones are the right thing for someone, you can buy it. But a real recommendation I can not pronounce.
