Is state tracking the hardest part of phone-use AI?

Reddit r/AI_Agents News

Summary

The author observes that the hardest part of phone-use AI agents is tracking state changes, as mobile interfaces have more dynamic and interruptive UI changes compared to desktop, and asks for others' experience.

I’ve been looking at mobile agents recently, and one thing feels different from browser/computer-use agents. On desktop, a lot of tasks still happen in relatively stable surfaces: browser tabs, files, terminals, web apps, APIs, etc. On phones, the agent has to survive more messy state changes: \- keyboard opens and changes the layout \- permission popups interrupt the flow \- apps reload or switch context \- a wrong tap can put you in a totally different screen \- the same task may cross multiple apps So my current guess is: the hard part is not “can the agent tap a button?” It’s whether the agent can keep track of where it is after the UI changes. For people who have worked on mobile automation / GUI agents / Android agents: does this match your experience, or is another failure mode more painful?
