The Xperia Z4 was recently launched exclusively for Japan and became available for purchase with the country's mobile carrier NTT DoCoMo. However, Japanese users soon began complaining about the Xperia Z4 overheating and the Japanese carrier even officially confirmed that that the device had overheating problems. Moreover, performance tests conducted on the Xperia Z3+ in the Netherlands also revealed overheating issues, particularly when the camera was used to record HD videos. Users of the Xperia Z3+ complained of experiencing overheating issues while playing games, watching HD videos on Netflix, or recording a video with the device.

Speaking to a Dutch publication, Sony acknowledged the overheating issues in the Xperia Z4 and Xperia Z3+. The Japanese tech giant said it was aware that the overheating was being caused by Qualcomm's controversial Snapdragon 810 chipset and promised to release a software update to fix the issue.

Sony seems to have kept its promise, as a new firmware update for the Sony Xperia Z3+ (E6553) and Xperia Z4 Tablet (SGP771) has reported to have been just received certification from the PTCRB. The update carrying the build number 28.0.A.7.24 as compared to the current 28.0.A.6.8 is likely to resolve the overheating issues being created by the Snapdragon 810 processor powering both the Sony Xperia Z3+ and Xperia Z4 Tablet.

Most manufacturers of other smartphones powered by the Snapdragon 810 chipset have 'fixed' their overheating issue with the use of thermal throttling to keep the processor sufficiently cool by slightly compromising on the handset's overall performance. It remains to be seen if Sony's firmware update will completely resolve the overheating issues in the Sony Xperia Z3+ and Xperia Z4 Tablet.
