It has been hardly a few weeks since Sony's flagship Xperia Z3+ (aka Z4) hit stores in select markets of Asia and Europe; now, the newly bought Sony device owners have begun complaining regarding the over-heating of the smartphone.

Taking note of the increasing number of complaints lodged by consumers, Sony has issued a press statement acknowledging over-heating issue and has promised to release a software patch to fix the glitch.

"The Xperia Z3 + is a high-performance 64-bit octa-core device with advanced camera technology, in some cases, additional heat can cause additional heat can stop! Enabling applications can also be felt by the user through the glass on the back. This is normal for the unit and no cause for concern," said the official Sony spokesperson to GSMInfo, a Dutch technology blog.

That being said, the overheating issue is plaguing other tier-brands as well. Flagship smartphone HTC One M9 did not elicit good response from the public after the launch and to add more woes, it was also reported to have hit by the same heating issue, the culprit being the Snapdragon 810.

Top smartphone-maker Samsung too faced similar issues during the test run of Galaxy S6 (and S6 Edge). The South Korean firm, anticipating negative publicity after the launch of flagship smartphones, ditched the Qualcomm chipset.
