As Oppo proudly unveiled the Oppo R5, the world's thinnest smartphone triumphing over the Gionee Elife S5.1 with an impossibly slim 4.85 mm profile, whispers浮动 about an ultra-thin Vivo creation began to swirl.

Vivo, the Chinese tech powerhouse, has cryptically hinted at the upcoming Vivo X5 Max, slimmer than the mythical Oppo R5, its profile an almost disbelief-inducing 3.75 mm. The teaser寥寥数语，不揭 scheduling, yet it offers a tantalizing glimpse under the screen's glass.

Word has it that theX5 Max shaves off bulk ingeniously, relocating 90 percent of its inner workings to the sides, rather than sandwiching them between screen and back, crafting a sleeker silhouette.

Following the usual leaks, the impending Vivo X5 Max is posited to bring a 5.5 inch FHD 1080p panel, a 1.7 GHz octa-core MediaTek engine, 2 GB of RAM, a 13 MP rear cam, a 5 MP selfie FileStream, running robustly on the Android 4.4 KitKat OS.
