My husband bought a Lenovo 850 after a lot of speculation. It was a risky act and now we regret it.
The mobile was a bit heavy and also seemed too bulky for constant daily use.
It is two years now and the mobile has started causing problems. It hangs and also switches off while calling.
We invested in lenovo thinking it was a good name in the field but other companies are even more better in mobile production. We have decided to buy a new mobile and still are trying to make the old lenovo work because video streaming and audio was good. It also has an excellent speaker when we call a person and want to put it on speaker mode.
I will not recommend Lenovo because my bil also had such problems.
The overall performance of Lenovo in the mobile sector is poor as certified by mobile retailers also.
