I have purchased lenovo vibe k5 note last year, I dint found any major issue as such. it is working fine till now, but few days back suddenly I found that my phone speakers stop working, around 3days I have used ear phones then after 3days again it came back to noraml working condition and it is working fine now. I have purchased it for 13999.
Only one bad thing is speakers some times misbehaves, but after 1 year I found this issue
