Few modifications in Food Delivery Android App

TAPZU is a hyperlocal delivery app with services like Food, Meat, Grocery, Taxi with multiple vendors We are already live in google play store. Need some changes in Android App. Most of them are UI part. 1. "Customer app, Merchant app, Driver" should work in every android device. (Firebase OTP is not working in few mobiles in customer app) 2. Enable Near by merchants. Actually disabled in home page (Show min 10 near by merchants) 3. Customer can "Add, Edit" the address from home page as the change address is available in each services like food, meat, vegetables(Remove from the services) it should also reflect the address in checkout page. Save (Home, Other) option it customer profile in Admin Panel. 4. Move sliders every 5 seconds. 5. Show all available restaurants(Only Food Service) which are open one by one in home page like swiggy. 6. Menu option should close automatically when customer selects the category. 7. Show a message before placing order "Once order placed cannot be cancelled." 8. Sometimes showing zero rupees in checkout while adding item through search option & when customer clicks on search the keyboard option should appear. 9. Change complete order assigning process. Will discuss details through chat. 10. Load home page very fast. (As it is taking time to load) My Budget is Fixed. Looking for a developer who has complete knowledge on how logistics and last mile delivery works. We will have long term relation if this works well. Lets work on IOS after this tasks and lot of changes need to work on Android too. As these are high priority changes. Good Luck.
