few days ago whatsapp implemented end to end encryption, till date telegram is using encryption. i think whatsapp must add search functionality like telegram. it will be hit.
I use both WhatsApp and Telegram. But every time I have to return to reply to someone on WhatsApp it feels like I travel back in time and bash the message in like a Neanderthal on an iRock. So glad most of my friends have moved to Telegram because it's much more productive and intuitive
