The second problem noted by new owners regards an overheating issue when capturing 4K video, and this can lead to the forced closure of the camera app. Sony Singapore has been pretty quick to act on these concerns and has already issued an official statement on the matter. This is what Sony had to say on the overheating problem –
“We are aware of some users encountering issues when shooting 4K video for extended periods. Shooting movies in high quality 4K resolution can make significant demands on your phone’s processor and battery life, as well as phone memory. Therefore for the best experience, we recommend you install a high capacity SD card (Xperia Z2 can take a card up to 128GB) and shoot 4K video in short bursts of no longer than a few minutes at a time.”
