SmarTect Gigaset GX4 Tempered Glass Screen Protector, 9H, 0.3 mm, 3-Pack

The 0.3 mm tempered glass is designed to help shield the Gigaset GX4 display from everyday scratches and knocks, while its clear finish keeps the screen visible. The pack includes three protectors, so there is more than one available for fitting or future replacement.

Its 9H hardness rating, anti-fingerprint coating and high touch sensitivity make it suited to regular mobile phone use, from checking messages to browsing on the go.

What matters most

This screen protector is made for the Gigaset GX4, with stated dimensions of 15.2L x 7.2W centimetres and a glossy, ultra-clear finish. SmarTect describes the glass as shock-resistant and scratch-resistant, those claims indicate the kind of protection it is intended to provide, rather than a guarantee that the phone screen cannot be damaged. The glass is also described as anti-bubble and designed to retain touch sensitivity, which matters if you use the display frequently and do not want a protector to feel like a separate layer.

You’ll like it if you want a rigid glass layer rather than a flexible TPU film. Tempered glass is the more relevant choice here for resisting scratches and impacts, while the supplied product information describes TPU as flexible and better suited to curved displays with basic protection under light use. The oleophobic coating is intended to reduce fingerprints, grease and dirt marks, helping the display look clearer between cleans.

Cleaning & care

A fitting kit is included: three wet wipes, a microfibre cloth, two anti-dust stickers and an English instruction manual. These accessories are there to help clean the screen and remove dust before application, when particles trapped underneath can affect the finish. The protector is described as bubble-free when fitted with the included installation and cleaning kit, but the result still depends on careful application. Work with a clean screen and follow the instructions rather than rushing the placement.

The glossy glass suits buyers who want to keep the display’s original appearance. It is not a matte or privacy-style protector, so those looking specifically to reduce reflections or restrict viewing angles should consider those finishes instead, they are mentioned as separate options in the SmarTect range, not as features of this pack.

Everyday use

For a typical day, the glass can sit between the GX4 display and small everyday hazards such as keys or coins in a bag or pocket. Its stated high touch sensitivity is intended to let you continue using the touchscreen normally, while the anti-fingerprint coating addresses marks from regular handling. The three-piece pack is practical if you want spare protectors available without buying a single replacement each time one needs changing.

SmarTect says the protector is compatible with the original Gigaset GX4. Its fit is intended to work with most phone cases, though the provided information does not name specific cases. There is also a fit caveat for curved smartphones: the protector covers only the horizontal surface. It may not suit you if you need glass coverage around curved screen edges, in that situation, a flexible film may be a better fit, although the supplied comparison describes it as offering more basic protection under light use.

Is it worth it?

This pack is worth considering if your priority is a clear, rigid screen layer for the Gigaset GX4, with cleaning accessories and spare protectors included. The 9H rating, anti-fingerprint finish and stated touch sensitivity address common day-to-day concerns without changing the phone’s intended display appearance. Choose it over a flexible film when scratch and impact resistance are the main considerations. If edge-to-edge coverage on a curved screen is essential, the stated coverage caveat is the deciding point: the glass is designed to cover the horizontal surface, not the curved edges.
