[Xperia Z4/Z3+ Q&A, Help & Troubleshooting] rdosti:
With the waterproof Xperia Z3v, you can take pictures with the best smartphone camera while swimming in fresh water for up to 30 minutes. You can even dive down to 5 feet with it. Just remember that all the covers for the micro USB port, the micro SIM slot and the memory card slot must be firmly closed.

Do you even read what you copy and paste from a website or do you just like arguing for the fun of it ?

Please Reference: http://support.sonymobile.com/in/dm/waterproof/

You can dive down, but not use the phone in active mode. You can swim (swimming is not taking under water videos) with it.

In fact it is a marketing page very well written without mentioning what you can't do because thats exactly what it is for - marketing and selling ! You need to find the right page to get the warranty details as well as "waterproof allowed and not allowed".However the link I have sent on another thread you tried to disturb with wrong information - clearly instructs what not to do , which indeed can void your warranty.

Please get your facts straight before insulting or disrespecting a fellow member. On another thread you have tried to sell an app. Are you planning to take responsibility for any damage to anyone's phone by giving them wrong advice. If you want, go over to Amazon.com and look at under water cover reviews and even reviews about any of Z models where customers as well as cover sellers have discussed this in detail as well.

You are wrong. It clearly mentions it should not be "fully submerged period".

Forgot "the features". You need to check the water proof warranty details. Features is all marketing crap. Ask the support center. Do not guide people wrongly without checking or call the support team!

You attempted to give wrong information here as well :http://xdaforums.com/xperia-z4/help/how-underwater-camera-usage-video-photos-t3181236

Which I promptly replied with sentences from the Sony Website Page all about waterproofing for all their devices, not just any one or two.

Anyways to summarize the details:

From the Sony website (Basic Care section) :

1. "The IP rating of your device was achieved in laboratory conditions in standby mode, so you should not use the device underwater, such as taking pictures. Do not use the device to take photos while performing any type of activity underwater, including diving or snorkeling."

2. "Do not expose the device to seawater, salt water, chlorinated water or liquids such as fruit drinks, liquid detergent and vinegar."

--- So there goes any thought of using it in chlorinated water too.

3. Warranty, repairs and customer service

It’s important to know that your warranty does not cover damage or defects caused by abuse or improper use of your device. Also note that compatible accessories, including batteries, chargers, hands-free devices, keyboards and micro USB cables, are not waterproof and dust protected on their own.

4. If the device is "accidentally" exposed to non-fresh water, such as chlorinated water from a swimming pool, always rinse your device off using fresh water.

Notice: Accidentally and not "On Purpose".

From the Website (refer to the last point)

"Taking photos and movies in wet surroundings. Remember not to use the device underwater. If you accidentally get the device wet with non-fresh water, wash the device with tap water."

Again all you need to know is clearly and publicly available on their website.

I have asked Sony Service center and they have clearly mentioned you can't submerge it and if there is any water damage, it will "NOT" be replaced for free.

If anyone has a story about getting away with a free replacement - go ahead and let us know :)

By the way if you really want to go to the link YOU Mentioned, it does not mention you should take photos UNDER water. It just says you can take it with you. There is no mention of submerge in the link you provided.

Better yet just called Sony Service center and ask them. Genuine ones will tell you that indeed warranty is void if you mention to them even by mistake you took it under water and used in actively or submerged it. Doesn't even matter what water it was if it was not on standby.
