Mobile accessories / Why quotes differ
Similar appearance.
Different quotes. Why?
Make the specification, quantity and delivery scope comparable before judging the unit price.
Align these six parts of the quote.
Glass and thickness
Confirm the material grade, finished thickness and strengthening information. Ask whether the thickness includes the adhesive layer.
Edges and curved areas
Ask where the curve is: in the glass body, the polished edge or an added material. Request a drawing and the actual process description.
Optical features and surface finish
Specify clear or privacy performance and any AR, AF or AG treatment separately. Ask for the test method, conditions, batch and sample size.
Adhesive and bonding
Confirm the adhesive structure, coverage and installation conditions. Check samples for bubbles, white edges, rainbow effects and residue.
Installer and retail packaging
List what is included with each piece: protector, cleaning kit, installer, instructions and packaging. An installer is a configuration, not a guarantee of fewer returns.
Quantity, inspection and delivery
Align quantities per model, minimums, sample-to-batch consistency, lead times and defect handling. Product prices here include retail packaging; transport is separate.
See the actual configuration.
Watch the installation steps.
001 · manual placement
Peel away the release material, align by hand and observe bonding. Screen cleaning is required but is not shown in this excerpt.
Titan · installer operation
Place the installer over the phone, pull the strip and remove the tool. The clip demonstrates operation without identifying the clear or privacy variant.
Compare samples on the same phone model under the same conditions before committing to the batch.
An observation is not a performance test.
The screen-viewing clip helps you identify what to inspect. It does not establish a privacy angle, light transmission or universal phone compatibility.
001 · screen observation
Change the viewing direction and observe the screen. Treat this as an observation clip, not a standardized optical test.
