Update existing ionic app

I need upgrades completed to an existing ionic app and also supplied with the source code after updates completed.

Updates to app....


1. There is a filter at the top of the results listings page on the app.

Presently when a product keyword is entered into the filter keyword field it is not returning correct results on the results page.
I need it to return the proper results. It is not filtering keywords like location, product name etc.. from the database.

This is also happening on the full screen search displayed on app startup. Can you fix this please.

2. There is a phone icon on the app listings and map results page.

When you press the phone icon it immediately calls the number on the phone. I need it to display number on phone ready for call, not call number immediately.

3. When launching the app it shows a grey screen momentarily before opening loading animation.

I would like to make this momentary screen white colour or get rid of it. Either is good.

4. When logged in on the app on the left side slide in menu says 'test developer' no matter who is logged in.

I need this rectified so that it displays the name of the specific account logged in.

Whoever decides to do this project I would also need an ongoing relationship for further tweaks to the app.

Many thanks
