Ever since Qualcomm launched their Snapdragon 810 processor there have been reports of overheating issues with the processor, although Qualcomm has said there are no issues with the 810.
Now owners of the new Sony Xperia Z4 in Japan are reporting that their handsets are overheating, there are a number of reports on Twitter about the issue.
As yet there is no official response from either Sony or Qualcomm about the reported overheating issues on the new Xperia Z4.
Sony are also launching a version of the Xperia Z4 internationally, the handset is launching as the Xperia Z3+ and comes with a Snapdragon 810 processor, we wonder if this device will have the same issues.
