Lenovo vibe B is one of the worst android smartphone. I bought this lenovo phone three years ago because of low budget I had to buy that mobile. When I bought that its cost was 6500/- .it has 1GB of RAM and 8gb of ROM. They say that it has 8gb internal storage but when I boot the mobile so opened file manager and I saw it had only 3.75gb of internal storage which was very disgusting thing. It has 5MP rear camera with flash which is also worst clarity camera. Front camera is of 2MP camera which is worst part of mobile. The quality of front camera is equal to VGA camera of keypad mobiles.Also the mobile display is also very small and look like very very old model mobile. It has Android marshmallow .the most disappoining thing about this phone is it started hanging in only one month and if more apps got installed then we cannot install more apps. It shows the command ’system overlay detected’while we try to install new apps after 3 months of use. Overall I can say that lenovo vibe B is the worst smartphone ever made. Now the mobile become completely worst also the battery is also worst and drains fast. So I request everyone not to buy this mobile go for better smartphones.
