When I first opened the app I could write my own tag ...
Probably you noticed that because your tag matched one of the already existing ones in the site you've chosen.
... but after while only search tag was available.
That was probably because the tag you where trying to enter didn't match any existing.
It was annoying1 as I couldn't add new tag.
Besides you cannot do that from the android-app, you can add tags only with a certain reputation. The exact numbers are site specific, but can be found in every site's help center at the Privileges section.
Have a look at the explanation from the all tags overview page (emphasis mine):
A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.
That you can't add tags without this minimum reputation is made up for reasons:
- You should have gained some knowledge about the existing tags at the site, and how to use them properly for creating or editing questions
- If tags could be created arbitrarily by everyone, they wouldn't add any benefit for focused searching.
1)That something just annoys you isn't usually a good reasoning for a feature-request. At least you should add a comprehensive proposal what exactly should be changed, and how so in detail.
