Zisty

• Nothing left behind: photos and videos that arrived while your phone was locked are there the moment you return. • Smoother sending: photos sent while a large video uploads no longer wait in line; they arrive in a second or two. • Smarter routes: when one path slows, downloads move to the faster one without disturbing the rest, and messages that piled up arrive sooner once you are back online. • Steadier history: reading back up a chat, you stay where you are; at the bottom, new messages simply appear. • Steadier calls: the sound barely skips when your phone switches networks, a shaky network no longer drops the call while it switches routes, sound comes back by itself after the system interrupts it, and you hear all three beeps when the other person hangs up. • Expired messages clear away without a stutter, and files that have expired or been deleted are no longer downloaded again and again.
