Fine for everyday use: The business smartphone for tough working environments

How to recognise a good smartphone: It can even withstand major stress. The Gigaset GX4 PRO is ideal for active people who spend a great deal of time outdoors and need a phone that can withstand the challenges of hard work. It will be a quality product "Made in Germany"; it stands for robustness and durability. The GX4 PRO is also convincing when it comes to performance and capacity: Its enduring 5000 mAh battery can be charged at a superfast rate up to 30 W. But you can also easily remove it and replace it with an exchangeable battery. A powerful octa-core processor works inside this smartphone; it attracts attention outside with the new LED spotlight ring.

Resistant to water, dust and shocks: The Gigaset GX4 PRO case

Other smartphones are up against their limits when they come into contact with dust, dirt or water. You can rely on the Gigaset GX4 PRO: It has a robust case which complies with military standard MIL-STD-810H and has IP68 dust and water resistance. This means it's just right for work and outdoor activities. Its structured polycarbonate back gives you a firm grip, and the display is protected by scratch-resistant Corning® Gorilla® glass. The frame of the TPU dual-injection case is made of aluminium, magnesium and titanium amongst other things, and it has no problems with falls and strong shocks. The GX4 PRO also withstands extreme temperatures; it's also waterproof up to a depth of 1.5 meters for 30 minutes. This means you can enjoy it for a long time; and you can clean it with clean water, soap, disinfectants or alcohol.

It lasts a really long time: An long-lasting exchangeable battery

When something takes a long time, persistence is needed: The Gigaset GX4 PRO's 5000 mAh removable battery lasts for at least two days with average use, and much longer in standby mode. You can listen to music for up to 56 hours and watch videos for up to 16 hours; the talk time is up to 45 hours (4G). When there's no time to charge, just change the battery: It's easily to remove - which means your GX4 PRO is ready for use again in seconds. It's also fast with wireless quick charging up to 15 W and super-fast charging up to 30 W. Gigaset BatteryLife+ technology also ensures enhanced sustainability as well as a longer lifespan, increasing battery life by up to 50% with a pre-set charge limit at 90%.

Adaptable: The flat dual camera system

If you want pictures to speak, you need the right equipment. You don't necessarily need heavy photo equipment for this: With the Gigaset GX4 PRO dual camera system, you are equipped for every use. The integrated 48 MP wide-angle + 8 MP ultra-wide-angle are perfect for large objects or panoramas, fascinating close-up or detailed shots will be successful with the macro camera. If you like taking high-resolution selfies or video calls, you will have plenty of fun with the 16 MP front-facing camera. Of course, the GX4 PRO can also record videos in QHD 1440p with 2160 x 1440 pixels. The dual-LED flash comes in very useful for photos as well as videos: During recording both LEDs light up continuously and illuminate the surroundings even at night or in poor lighting conditions.

Gives signals and looks good: The new LED spotlight ring

Which signal would you like? Ringtones can be set on smartphones, and of course also on the Gigaset GX4 PRO. But what if you can't hear the sound? When sounds around you drown out everything? Even then you won't miss anything! The new LED spotlight ring around the camera on the back of your smartphone alerts you to notifications or missed calls with a pulsating light: Just leave your GX4 PRO with the display on the table (or workbench). You can also set the ring as a light amplifier in flashlight mode. And if your smartphone is lying with the display facing up? You'll still get a visual notification: There is a notification LED on the front.

The Gigaset GX4 PRO display

Why a little V makes all the difference: The 6.1-inch HD+ V-notch display on the Gigaset GX4 PRO has a tiny V-shaped notch at the top edge on the screen, and the front camera is hidden in it. This makes the screen appear larger, and the content is displayed clearly - whether movies, videos, or navigation apps. The display is protected by scratch-resistant Corning® Gorilla® glass which means your GX4 PRO is safe even for outdoor use. It will not let you down in the sun, wind or rain: The increase in brightness when there is sunlight (550 nits) ensures good legibility even in very bright conditions. Thanks to the high touch sensitivity, you can even operate your Gigaset smartphone with wet hands or gloves (up to 2 mm thick). This means your hands can always stay warm and dry even outside.

Gives performance: The octa-core processor

If you don't like waiting around, you need a smartphone with a high performance and plenty of memory. A smartphone like the Gigaset GX4 PRO: Smooth app usage and data editing is guaranteed with the 2.2 GHz octa-core MediaTek Helio G99 processor. It handles demanding graphics applications quickly and reliably. The Android™12 operating system (upgrade plan to 13 and 14) in this smartphone is also reliable. It features Bluetooth 5.2 and NFC for secure and wireless connection.  

By default, the GX4 PRO comes with Android Enterprise™, which offers numerous advantages to businesses as well as employees in terms of management and everyday professional use.

Stores and unlocks: More convenient features of the GX4 PRO

The Gigaset GX4 PRO's face recognition feature ensures that you alone have access to your smartphone. The fingerprint scanner also works biometrically, and it can be unlocked just as securely and conveniently. You can also use your finger to go to your favourite functions or apps: Whether you want to activate Google Maps, Google Assistant, SOS, the flashlight or camera: With the programmable function key on the left of the casing, you can open your personal favourite functions in seconds. The GX4 PRO also has a triple slot for dual-SIM (or nano-SIM + eSIM) as well as memory expansion. This means: You can insert both a private and a business SIM card - and make all phone calls with one device. Practical!

Lets see: A good smartphone "Made in Germany"

Where origin matters: The Gigaset GX4 PRO is made in Germany, so you can expect the best features, high quality standards as well as top design. This is unprecedented because Gigaset is the only company in the world to produce smartphones in this country. For seven decades we've been working on modern telecommunications solutions at our production site in Bocholt; we vouch for this with the "Made in Germany" quality label. We are proud of what we have already achieved, and with our "Fair for Future" promise we are also looking ahead: Our products are still the focus, of course, but issues such as fairness, sustainability and the fight against social inequality are equally important. After all, we all want to live well and carefree in the future.

Numerous customisation options for companies

Different companies have different needs. Gigaset meets the requirements: The GX4 PRO can be customised for corporate orders. We achieve this with Gigaset's production and manufacturing facilities in Germany. Even for relatively small quantities, company logos, IMEI numbers, department designations or other individual information can be engraved on the back of the device; this enhances your employees' identification with the company and also helps to prevent theft. And the installed software can be defined in advance if necessary. Companies can configure the GX4 PRO in a very flexible way, from the home screen with their own company logo to the selection of apps, details about device management and a choice of background images and ringtones - the company jingle is even possible here. Accessories including protective film, headphones and individual packaging can also be combined to meet requirements.

An investment that pays off: The Gigaset sustainability promise

At Gigaset, we are always looking at how to make good things even better. Sustainability is important, which is why we produce high-quality smartphones like the Gigaset GX4 PRO which you will enjoy for a long time to come. In terms of packaging, we invest in the latest environmental standards (FSC®-certified, licence number FSC® N003454), and we offset CO2 emissions generated during packaging production with the help of our ClimatePartner projects. Inside the packaging, we have completely dispensed with plastic (apart from the adhesive film to protect the display). If you intend to produce sustainably, you have to constantly question your actions and break new ground. At Gigaset, we do this as part of our "Fair for Future" promise. This means we can look to the future with confidence together.
