The UniStrong UT10 is not your average consumer smartphone. It is a rugged smartphone that is targeted more for use in commercial entities such as a logistics company or for geographical surveying.

The dual-SIM phone looks much bigger than an average smartphone. It is around 20 per cent bigger than a Samsung Galaxy Note9, which has a 6.4-inch display, despite the UT10 having a smaller 6-inch full high-definition display.

The reason for its large size is the amount of protection it has. It is like having an in-built armour case. Its water-resistance rating of IP68 means it can be submerged in water to a depth of 1.5m for 30 minutes.

It has also been tested to withstand drops from a height of 1.5m and can function in conditions of up to 60 deg C.

To test its ruggedness, I dropped the UT10 several times on a concrete floor from a height of 1m. A couple of drops were with the screen facing down. It got some scratches, but none on the screen. And the smartphone remained in good working condition.

On the bottom front of the smartphone, you will find the power button, two customisable buttons and a Function button. The volume control buttons are on its right, while you will find a push-to-talk (PTT) button on the left.

This dedicated PTT button is probably the biggest selling point of the UT10. UniStrong Apac, formerly Navicom Technology, works with Internet Protocol PTT (IP-PTT) service provider ProPTT2 to offer PTT solutions to companies.

IP-PTT works via Wi-Fi or 3G/4G networks, thereby allowing businesses to create their own secure and intuitive communication network.

The ProPTT2 app is integrated with UT10's PTT button. When you press the PTT button, you can immediately talk to someone over a communication channel. The two customisable buttons are - by default - used to switch channels.

The app also allows for video PTT and real-time video sharing, which might be useful for first responders attending to emergencies, whereby they can show doctors the injuries of patients and doctors can immediately advise on the possible actions to be taken.

This IP-PTT requires a subscription fee of $9 a month. However, UniStrong Apac is having a promotion till March where it is selling the UT10 at $990 (usual price $1,599) with 12 months of free PTT subscription.

UniStrong also offers plenty of accessories, such as a vehicle dock and hand-strap, to go with the UT10. One useful accessory is the barcode scanner ($229) that comes with a hand-strap. This barcode scanner connects to the UT10's rear and users can press the Function button to scan the barcodes of products.

The UT10 is loaded with the stock Android 8.0 mobile operating system. It does not come with skins or modifications that usually slow down a smartphone.

However, the UT10 is not exactly fast. In the Geekbench 4 benchmark tests, it scores 940 (single-core) and 4,631 (multi-core). Comparatively, the Note9 has scores of 3,760 points (single-core) and 9,094 points (multi-core). Guess companies would not want their employees playing Pokemon Go on this smartphone.

With a 8,000mAh battery, the UT10 lasts a stunning 20 hours and 11 minutes in our videoloopback test. With normal use, it lasts three days before it needs to be charged. Great for those working outdoors, doing deliveries or medical response teams - the last thing they need is a flat battery.

•Verdict: For commercial entities or organisations that require IP-PTT communication network, the UniStrong UT10 is a strong proposition.
