Hi friends this sudheer, I have used YU yureka.I had great expectations with YU yureka plus.but unfortunately it did not meet my expectation. The android version is KitKat.however it is written in ad lollipop. There is no cyanogen.I m still waiting for update.After buying the Yu phone I face some charging problem. on my phone warranty is finished. or phone have still the same problem. every time take 45 days to return the device without solved problems. Please dont buy this device. I would suggest think of twice while buying a YU product because the after sales service is pathetic, my phone was dead while updating and its been 45 days I havent got my product repaired. Whenever I call customer care I am asked to wait for 48 each time.
