Sony has responded to new claims that the Xperia Z3+ handset suffers from overheating issues.

As a solution, the Japanese company promised to release a software update sometime this summer.

The issue was raised to Sony by Dutch tech site GSMInfo, GSM Arena has learned. While conducting tests on the Xperia Z3+, which involved using the device's camera and playing high-graphics games, the site noted that the handset became warm to the touch after a while.

The device then began to display warnings about the handset's temperature which then led to the forced shut down of certain apps.

This is almost the same experience that YouTube user Btekt went through last week when testing the Xperia Z3+ camera, as reported by Android Headlines.

Due to the results of the tests, various sources noted that the overheating problem may be caused by the device's chipset, which is the Snapdragon 810 from Qualcomm.

Although the processor has been rumored to cause temperature-related issues to smartphones in the past, Qualcomm clarified that the latest version of the Snapdragon 810 chipset has eliminated this problem.

However, even though the Xperia Z3+ is running on the Snapdragon 810 v2.1, it seems the new version of the chipset is still suffering from heating problems.

GSMInfo immediately notified Sony regarding the results of its test on the Xperia Z3+. In response, Japanese electronics company admitted that the handset is prone to overheating issues.

Although users shouldn't worry about this, according to Sony, the company promised that it will release a software update this summer to fix the problem.

GSM Arena speculated that the update may focus on tweaking the clock speeds of the device's CPU and GPU to limit the times these components reach their maximum rates.

Although this can prevent overheating, the site noted that it could also negatively affect the device's overall performance.
