phone has been working fine for last week since battery has come to full potential. but today the phone started to heat up a great deal at this time the battery was at 67%,within 20 mins battery level was down to 14%. in spare parts it says screen is running at 99.9% and running is at 100%. whats a bit odd is at the bottom of my spare parts page theres a small box saying http error 405,the service you requested is not avalible. ive restarted the phone a few times but the same issue just carrys on.
