If you open the audio context you should see consistent latency as long as you keep it open, but each time you open a new audio context you might end up with different latency. You should not see jitter within a single context.

Latency variance is known as jitter. What gives you the impression that it would be high on Android?
Having used nearly every flagship android device from the HTC Dream up through the Nexus 6p, and then switching to an iphone 6 and never looking back, except watching acquaintances use their android phones.
Also from talking to an engineer who worked on earlier generations of iphones, who said that every team had a latency budget that they could not exceed.
My impression is that Android has more latency variance than iOS. If that's true then it's important to be clear what the reported numbers represent.
