hello. I purchased my nokia 6.1 plus device on 6th september 2018 & recieved it on 16th September 2018. after i recieved my device was behaving very strangely. its temperature rises upto 55 degree celcius & total battery backup is only 12 hrs maximum with minimum usages. i requested to replace or return the device but Flipkart said that all these problems are very normal & we cant replace your device. What should I do now? I hav been cheated by all these thugs.
