<h1>Manufacturer launches limited-edition rugged smartphones with durability, AI imaging, battery claims, financing, extended warranty, and sweepstakes</h1> A smartphone manufacturer announced two limited-edition devices marketed for a festive season, touting durability claims (IP66/IP68/IP69, MIL-STD-810H), long battery life, advanced cooling, AI imaging features, and a heat-sensitive color-changing back. One model emphasizes antenna coverage and ruggedization; the other highlights proprietary 'GlowShift' technology and high-end camera capabilities. The announcement includes promotional financing, extended warranty offers, exchange bonuses, and a prize sweepstakes with cash awards and product giveaways. Products are offered through the manufacturer's and major online retailers' channels. The release is flagged as a paid press communication with the distributor disclaiming editorial responsibility.
