I placed order for Nokia 1 after viewing official advertisement. But, after viewing online reviews in many website, I think it will hang frequently. What can I do? If its performance will be poor, Can I back that to Nokia? My expectations are: the pone is running smoothly on running Youtube videos, Whatsapp, facebook, gmail, tweeter, 8-10 govt. apps, visit websites via google , video recordings. Can Nokia 1 be reach my expectation as stated earlier smoothly without hanging?
