On 3 Feb 2017, I received Android Nougat operating system(OS) update for my Samsung-S7 device and after the update, the device lost all the data and apps like Samsung Knox stopped working, for this to fix I went to my near Samsung service center on the same day and they degraded the system OS and reupdated the device to older OS, but when I checked later the problem was not solved, so again I went to the Service center on 4 Feb and now this time they created the job sheet and submitted my device and they told me that the device is showing warranty void and we have to overhaul the device software from ground up, for which I have to pay 230 Rs installation charges I agreed and left the device with them, later on, that day I received the call from service center and they told me that to fix the software problem we have to replace the device Motherboard and I have to pay around 18-19 thousand Rs for which when I questioned they gave no clear reason for charges and told me to call Samsung Customer Support the customer support told me that I don't have to pay for the charges because device is still in one year warranty, but the service center didn't agree and said that device is showing warranty void and we can not fix this under warranty, my device was working perfectly fine before OTA update and now I had lost all my device data and also I am been asked to pay for the charges, Please help regarding the resolution of this problem I had no other spare mobile handset to use and loosing my work productivity.
