Hi friends now I will share my experience with the whatsapp last 2 years onwards im using this app I real do love whatsApp and I use it a lot every days. Most of my friends use it and its much nicer to chat on there than on Facebook etc.Its focussed on one thing and does it well, chatting. I ve never seen WhatsApp go down and I ve never had a technical issue with it whatsoever. Ithink it’s very reliable and safe. It’s very convenient and seems to take up very little data if you’re not connected to Wi-fi. I like the backgrounds and the customisable LED colours. Plenty of customisation and options available. I hope you understand my review
