Want to experience the slowest android app? Install paytm. If you open the app it will load for 5 minutes Even if you have 20Mbps speed connection and best class mobile. After entering your number it will load 15 minutes at least select the operator and circle(you can’t select manually) for promo code and payment 15 to 20 minutes. It is better to run to street end shop and recharge.
You can burn some calories and tension free. I contacted support and developer many time. They just instructing me to update the app(I am already using update one) restart the mobile, turn off wifi or mobile data turn on again and bla bla bla
