CARE & MAINTENANCE​

___________________________________________________________________________________________________

[IP55/58] Waterproof:

​

As you are well aware our device is water proof. With this comes some drawbacks.

Speaker & Mic: Because there needs to be a semi-permeable membrane covering these, the amount of sound transfer is less than what we have experienced with non-waterproof units.

CARE:

-Do not use your device in salt water. This will perish the membrane, and cause water damage to the speaker / mic.

-Do not wash or use your device in soapy water. The soap will also dissolve the membrane, again causing water damage.

Dust & Water Proof covers:

​

The ultra has covers that stop dust and moisture entering the device. There are rubber O rings that fit nicely into rubber connectors. This provides a seal against water and dust. However there will be times that small dust/ grit will gather around these O rings, and if not cleaned regularly and carefully then this will cause the O rings to perish, or even worse, allow water to enter.

CARE:

-Use cotton buds to wipe around the O rings on the flaps, and around the device rubber seals. Keep them as clean as possible

** DO NOT blow into the ports in an attempt to clear the dust. This may cause the rear panel to lift, and delaminate from the Aluminium frame **

MicroUSB Cover:

The covers that keep the Ultra waterproof stand to get a lot of use. Plugging and unplugging via USB cables, inserting and ejecting a microSD card. Each time friction occurs on the O ring and rubber connector we risk creating gaps, and increasing the chance of water entering.

CARE:

One option is to use the magnetic connector to charge the Ultra. These come in various forms, ranging from an actual dock (DK30), to a simple cable. Available on eBay or DX-Box

Frame & Structure:

[MENTION=1726119]Imdking[/MENTION] posted a thread about his device twisting. When placed on a flat table it rocked, indicating that it had bent.

The Ultra is made of an Aluminum frame and toughened glass covering front and back.

The Ultra can fit in a pants pocket, however I am sure you have noticed when you sit down its pushing the limits.

- Sitting down with the phone in the pocket may bend the frame. This could even lead to the glass corners popping out.

CARE:

-If you have noticed your device not sitting flat on a table/ flat surface. Then hold your device at the top and bottom. Twist the sides slightly in the opposite direction to correct it.

Screen Protection:

​

The Ultra comes with a rear and front screen protector. These are pre-applied by Sony. The rear comes off easily and can be replaced quickly. The front is more difficult. It has an adhesive that will make it very difficult to remove. (It is still possible to remove, but the Sony logo will also be removed)

** Sony's front screen protector has a coating on it that is supposed to reduce fingerprints. This film comes off!!! So beware. Removing Sony's protector and/or applying another protector overtop of the existing Sony protector is HIGHLY RECOMMENDED **

There are many on the market and depending on your needs, you may need to do a little research.

Options:

These are the only two I have tried. Super Shieldz was easier to apply, and was easy to slide your finger over... perfect. XtremeGuard attracted dust, and could not remove due to its stickiness, but is very thick. So may be more heavyduty

XtremeGuard - LINK Very clear visibility. Thick, tough. stretchable. Sticky. Once on, if you remove you'll need to throw away.

Super Sheildz - LINK Matte, anti fingerprint. Thin, stiff. Rigid. Easy to apply, remove and reapply.

Using water to apply screen protectors makes the job easy. Remember that screen protectors will allow water to evaporate through, it may just take a few days.

Hard Power Off:

No doubt at some time over the course of owning your Xperia Z Ultra, you will find yourself stuck. Your device wont finish its boot, or has frozen. There is a simple solution:
