Many of the recent waterproof Xperia smartphones and tablets come with the IP68-certification.
However, Sony is now warning its customers not to get Xperia smartphones too wet.
The question is why Sony backtracking now?
The company has been hesitant to repair devices with liquid damage.
If Sony promises that your equipment will withstand water and then it doesnt, youve been mis-sold that equipment.
Currently, no matter the kind of water, Sony does not allow full submersion underwater.
It says NOT to use any waterproof equipment for underwater actions, such as taking photos.
The fact that Xperia devices are still certified for water-resistance hasnt changed.
However, just be careful to not fully submerge it.
