I have been using Lenovo K3 Note for almost 1 year but I had faced lots of issues:
Cons:
a) Weak Signal reception
b) Phone gets hot while on using 5-10 mins call
c)Network reception is also low. I had to go to Lenovo Authorised Service Centre at Sahara Mall, Gurgaon. They replaced motherboard but then also the issue persisted.
d)Touchscreen started responding less now.
e)On using dual sim, phone starts behaving abruptly. Being a 4G phone, it should connect to 4G network. Instead it only works good on H+.
f)Good battery while I started using this phone but now it depletes like supersonic speed.
Pros:
a)Good display of 5’5"
b)Dolby stereo
c)Light weight phone
