I bought Lenovo S90 last year. First impression was ok but after a week I came to know that there are many problems I was facing. Which are as follows:
Worst speaker sound quality.
Sound recording is too poor. I generally attend many function where I have record lectures. But when I listen them again worst sound .
Main camera performance is not good
No application menu.
After 6 months one day my phone become brick. When sent to service center they returned after a month. But there were still many problems. Again sent to service center than returned 20 days. Third time again problem and after 3 months I got my phone back with marks of open set. So after sale service is poorest I ever seen .
So I recommend never buy a lenovo phone. I wasted my 19000 INR on this junk
