Inconsistent tags between OS, can't filter by Android

[maxkomarychev]

Environment

How do you use Sentry?
Sentry SaaS (sentry.io)

Which SDK and version?
@sentry/react-native: 2.4.3.

Steps to Reproduce

const transaction = Sentry.startTransaction({ name: 'app.loader' })
const span = transaction.startChild({....})
...
span.finish()
transaction.finish()

Expected Result

I can filter my transactions using tag os.name

Actual Result

Available tags are inconsistent between platforms, more specifically:
os.name is only available with value iOS but not on android (screenshots attached)

@maxkomarychev Device context on transactions was added in the latest Sentry Android SDK, you can update to the React Native SDK version 2.5.0 to get device context. I'll add this to the changelog to be more clear.
