interestingly enough, I had my wife inquire with samsung about her model (all 3 are the same but 1 is direct from Samsung, one from EE and another for my daughter, the Mrs bought it that one outright from CPWH.
samsung suggested first to do a repair service for all 3, then proceeded to say they should be replaced entirely through their respective retailers, when I mention mine was directly from Samsungs own website, I was told she thought it best to just send it back with a case ref from her for a refund so I could purchase a replacement faster than with testing first as I'm within consumer rights period still.
none of what was said by her made sense except the mention of yet another patch to come in March (planned no date) and I can see slight improvement on one device having been updated to 3.1 I battery but not heat, heats anywhere from 5 to 30 mins with silly low settings, everything optimised, 10-30% brightness max and the lowest resolution.
only networking feature or bypass sleep mode are WiFi and a specific work app that's optimised for And-11
i have spoken to a friend working for a ee csll centre too, apparently there's a fair few being sent in for testing or replacement but that the reports come back "normal"
I did call them about this a second time about the outright purchased one and my wife's both on a second call just in case, reply there was to wait 6 more days for a patch and see if it worked or they would do the pick up/ drop off with a replacement.
I was disgusted when told I might get a refurbished device
