Sony xa super heat after turning on data

[Jehiel34]

My one week old sony xa F3115 heats up realy fast after turning on my mobile data. Everything on the phone is working fine but the fast heat up really  bothers me, it heats up for just a few seconds after using Facebook and messenger. This problem appeared after 6 days from the purchase date. Please help me to fix this problem.

yes its get hot .. no other way to do .. but have u noticed at some times it wont heat at all . so outside temperature matters a lot .. better way is to get a wifi dongle and put a sim .. now v have lot of cheap plans in india ...
