I had bought a lenovo-A269i smart phone which is the worst smartphone ever I bought. It creating problems since I bought it. Not able to make calls at first attempt. The call drops automatically when there is incoming message or call. You can not transfer apps from phone to SD card( Phone storage is very minimum 512kb) you cannot download the apps to your SD card.
Only this phone from lenovo is worst but rest all models are good. The latest model from Lenovo S90 is an excellent model.
