As a Roblox developer, it is currently too hard to collect data on why player devices are crashing.
The Roblox mobile app already knows when it’s out of memory and sends a message to the player
Use case for this would be to track some key metrics in the game that may lead to potential crashes. You can already do something like this, by tracking the metrics over time and reading the last reported values, but there is never any way to know if the player crashed or simply left the game.
If Roblox were able to address this issue, developers will much easier be able to resolve any memory build up issues that may happen on time while people are playing your game.
