Pretty bad is also that it doesn’t save your last position. When you open the app through a notification it’s scrolled down to the last message. Whatsapp does that better….
Also you can’t zoom in on images. You first have to download them and then view them in the gallery app…
In Austria almost everybody i know under 30 uses WhatsApp. The only 3 people I still write SMS to are my Parents and a Friend without Smartphone. I used google+ messenger (formerly known as Huddle) before that with some friends but sending pictures sucks and using 4 different messeging apps is just stupid.
I don’t know anybody that uses something except WhatsApp, Facebook messenger or SMS.
