Thridify sorts every device into a tier automatically — full quality, guided AR, lite 3D, or 3D-only with AR handed to the phone by QR code — based on graphics memory and AR support. Shoppers never configure anything.
On devices with 2 GB of memory or less, Lite mode keeps browsing stable through long sessions and many finish switches.
Why 3D crashes on some phones and not others
Download size is not the problem. Decoded size is. A 2 MB JPEG texture at 4096 × 4096 takes about 64 MB of graphics memory once it is on the card, and a configurator that loads several finishes multiplies that. Phones with little memory give the browser tab a small budget. When the tab goes over it, iOS reloads the page and Android may drop the 3D context.
Halving texture resolution cuts memory to a quarter. On a phone screen the difference between 4K and 2K textures is usually invisible, while the difference between a smooth session and a reload is not.
What an adaptive viewer changes
The usual levers are texture resolution, how many finishes stay cached after the shopper moves on, shadow and reflection quality, and the device pixel ratio the canvas renders at. A good adaptive mode changes these silently. The shopper still sees the product, the options and AR where the phone supports it.
Detecting the right tier is harder than it sounds. Browsers expose memory hints unevenly (Safari does not report device memory at all), so viewers combine several signals, including the graphics hardware and whether the phone supports AR.
Why it matters
A 3D experience that works only on flagship phones excludes a large share of real buyers.
Questions about Lite mode (adaptive quality)
- Do shoppers have to switch Lite mode on?
- No. Thridify picks the tier for each device automatically.
- Does Lite mode change how the product looks?
- Fine texture detail is slightly lower on the devices that need it. Shape, colour, options and scale stay the same.
- Which devices get Lite mode?
- Low-memory devices, typically phones and tablets with 2 GB of memory or less. The device compatibility page lists what each tier gets.
