Digital callipers reveal architectural priorities instantly. We stripped each case down to evaluate core chassis thickness, corner ribbing, and protective clearances across both flat screen glass and protruding rear lens arrays.
The standard Stringberry Tough case incorporates two distinct parts: a dense, shock absorbing TPU inner lining seated inside an outer scratch-resistant polycarbonate exoskeleton. The outer perimeter measures 2.8 mm total wall thickness around the chassis rails, swelling slightly to 3.4 mm at the vulnerable four corners. In direct comparison, Casetify's standard Impact Case measures 2.9 mm along the side rails with ribbed elastomer inserts, while Burga's Tough model checks in at a bulkier 3.2 mm overall profile.
Camera isolation determines screen survival on modern flagship hardware. With Apple and Samsung extending their optical modules several millimeters outward, rear lip clearance is essential. Stringberry machines its dual-layer chassis with a dedicated 1.7 mm raised bezel camera protection collar. During flat-table slide tests, our camera lenses maintained complete clearance with zero surface contact. Front-facing protection is equally measured, providing a 1.4 mm forward lip that isolates tempered glass screen protectors from aggregate dust when resting facedown on concrete surfaces.
