SONY HAS ADMITTED that the Xperia Z3+ is overheating owing to problems with the phone's Qualcomm Snapdragon 810 chip.
The Japanese firm said that it will release a software fix in the summer to tackle the fault, which is a known problem seen in other handsets powered by the processor.
Sony acknowledged the overheating after it was detected in tests run by GSMinfo in the Netherlands, which found that the camera app crashed after a few minutes of video recording and that an unusual amount of heat was felt on the rear of the device.
Sony suggests powering off the phone several times a day while the fix is being readied, especially when charging the device. It also recommends that dissatisfied Xperia Z3+ and Xperia Z4 owners should contact the Sony service centre.
The Xperia Z3+ isn't the first phone to suffer problems with the Snapdragon 810 chip. Rumours surfaced earlier this year that Samsung ditched Qualcomm and used its own microprocessors in the Galaxy S6 due to overheating problems.
LG in April decided to go with Qualcomm's hexa-core Snapdragon 808 chip instead of the 810 for the LG G4, leading many to speculate that this was down to overheating.
Qualcomm at the time denied the claims, saying that LG's decision to use the Snapdragon 808 was made "over a year ago" and had nothing to do with the persistent rumours surrounding the 810.
Tim McDonough, head of marketing at Qualcomm, said at the time: "The decisions on which chipsets to put on which handsets come from over a year ago."
What's more, LG was quick to jump to Qualcomm's defence, saying that the G Flex 2 ships with the Snapdragon 810 and has had no problems.
Nevertheless, the news of the Sony Xperia Z3+ overheating doesn't bode well for the reputation of the 64-bit octa-core Snapdragon 810.
Sony unveiled the Xperia Z3+, known as the Xperia Z4 in Japan, last month. The handset delivers a quite impressive array of new features, despite the name suggesting minor updates.
Measuring 6.9mm thick and weighing 144g, it is 0.4mm slimmer and 8g lighter than last year's Xperia Z3, making it Sony's slimmest and lightest Xperia Z series smartphone yet.
The handset is available to pre-order at Carphone Warehouse now ahead of its UK release on 26 June, and can be picked up on O2, EE, Vodafone or the retailer's own iD network. µ
