With the Galaxy S10, Samsung celebrates its 10th anniversary Galaxy S phone by going big and bold. How bold? Each of the four new Galaxy S10 models is more impressive than the last: there's the cheaper S10E ($750, £669, AU$1,199), the Galaxy S10 ($900, £799, AU$1,349), S10 Plus ($1,000, £899, AU$1,499) and Galaxy S10 5G, the brand's first 5G phone, CNet says.

This is Samsung seeking to whip up excitement, roar back in sales and defend its title as the world's top smartphone brand. But the Galaxy S10 phones also represent a quest for perfection.

What does "perfection" mean to Samsung in 2019? An edge-to-edge screen with teeny-tiny bezels. The (remarkable) ability to wirelessly charge another device. An Infinity-O display that cuts a small circle (or oval) to make room for front-facing cameras. The world's first ultrasonic in-screen fingerprint reader, which unlocks the Galaxy S10 using sound waves. Up to four rear cameras. Up to 1TB of built-in storage. The all-new One UI. Android Pie. A cutting-edge Snapdragon 855 processor. And, in one case, 5G capabilities.

Samsung also lays claim to a screen advancement that reduces blue-light emissions, which studies have shown can slow or halt the production of melatonin, the hormone that signals our brain that it's time for bed.

The edge-to-edge screen feels natural. And yes, you still get a headphone jack.
