Sony Xperia X camera overheats on video nearly one year after the Xperia Z3+ snapper got hot
You would think that such issues would no longer be a concern for Xperia users since the new Sony Xperia X is powered by a Snapdragon 650 SoC. The latter is not known for overheating. But a recently recorded video, part of a review of the phone in Germany (comparing the phone to the Samsung Galaxy S7), shows the handset overheating after the camera app is opened.
Having said this, it seems that not every unit is overheating, and this could be a problem related to different firmware used on the phone in different regions. It might even be a simple case of a defective unit. Regardless, even the mere hint of an overheating issue is the last thing in the world that Sony needs, especially when it is trying to reboot its smartphone line and distance itself from the overheating that took place last year.
