Recently I had purchased Lenovo A6000+ from Flipkart.
And on the product, it was working fine till I had upgrade the Lollipop OS patch from Lenovo. post that the contacts in WhatsApp and dailer were not functioning properly. Stored names were not displaying in dailer and in WhatsApp, there was no contacts.
Lenovo advised for a factory reset after data backup. Also this does not support USB "On-The-Go"(OTG).And the box does not include a free set of earphone. Nonetheless, the product is worth the money.
