How It Works

QuantaCase · The complete visual usage guide

See the position.
Build the habit.

Nine views show how to hold, carry and position your case—and what the shielding layer does. Start with one principle: keep the shielded flap between you and the phone, and create distance whenever practical.

01 · Holding & calls

One grip. Three useful angles.

These views show the same folded-back speakerphone position from different sides.

Speakerphone setup

Fold the front cover behind the phone as shown. The small projecting edge gives you a place to support the case. Keep the handset away from your head and body when using speakerphone.

Speakerphone: front view

Rest your thumb on the projecting edge and support the phone securely. This angle makes the grip easier to see. Adjust for your hand size; distance remains the priority.

Speakerphone: rear view

This view shows the fingers behind the folded shielding flap. Keep the flap between your supporting hand and the handset, and avoid pulling the phone back against your body.

A call at your ear

When you need to hold the phone to your ear, close the front shielding cover over the screen, between the phone and your head. Prefer speakerphone at a distance when practical.

02 · Carrying

The shielded side faces you.

Pocket carry

Prefer a bag whenever possible. If pocket carry is unavoidable, close the cover and place the shielded front toward your body, with the rear camera facing outward. Return the phone to a more distant position when practical.

Bag or purse carry

Place the closed case with its shielding cover toward your body. Use the bag to create separation rather than pressing the phone against yourself. This view makes the orientation visible.

Distance first: a bag is preferable to a pocket when it creates more separation. When connectivity is unnecessary, consider airplane mode and check Wi-Fi and Bluetooth separately.

03 · On the move

Give the phone its own place.

In the car: dashboard holder

Secure the phone in a suitable dashboard holder, away from your lap. Position it without blocking your view, vehicle controls or airbags. Set navigation before driving and avoid handling the phone while moving. This illustration is a placement example, not a measurement of exposure inside a vehicle.

04 · Understanding the design

A flap with a purpose.

Know the shielded cover

The front folio flap is the side to position between you and the phone. Case dimensions and camera openings vary by model; the same orientation principle applies. See our red-flags guide for the design checklist.

Inside the shielding fabric

This original animation illustrates the idea of RF interacting with a conductive shielding layer. It is a simplified visual, not a simulation of a complete phone or a test result. A material’s laboratory attenuation does not establish the same percentage reduction in a person’s exposure.

Directional shielding is not a complete enclosure. No case eliminates every exposure or makes a phone risk-free. Correct orientation and distance remain important.

05 · Clear expectations

A small step. Used thoughtfully.

Is RF Safe Approved an independent certification?

It refers to RF Safe’s own design criteria. It is not an independent certification or a guarantee of health protection.

Does a fabric percentage tell me how much protection I get?

No. Material tests describe a sample under specific conditions. They do not establish a matching exposure reduction or health benefit for a finished case in everyday use.

Do these pictures match every phone model?

The illustrations explain orientation and handling. Exact case dimensions, camera openings and fit vary by model. Choose the listing for your exact phone.
