K3 note is realy a nice smartphone because of its fully feature phone specialy its processor is capable for all apps runing smuthly I m use this phone from 6 month
Truly I say u its not lag any point of you
Its full hd display also giving a great viwing experiance in every angle but battery is average its giving a full day battery backup for normal user but heavy user for 9 to 10 hours only
But overall its such a good phone for me
I refer this phone who buy smartphone within 10k its great deal believe me
