The vast majority of related ANRs recorded in the field are hanging on. The issue can still be reproduced with uncontrolled inputs, but a lot more text need to be pasted and parsed by Grammarly before the issue happens reliably. Switching to uncontrolled inputs decreased the amount of occurences of the issue in the field for us, but it's still happening a lot. 
The issue is a lot less impactful when using uncontrolled inputs rather than controlled inputs with a value prop. The issue happens sporadically when writing a paragraph of text, but it can be reliably reproduced by pasting a big wall of text (~1000 words), waiting for Grammarly to analyse it and display its green underlines, then typing. The issue does not happen when the Grammarly integration is disabled or when using a different keyboard like Gboard. This issue can be reproduced on earlier versions of Android as well. This integration is now enabled by default with Samsung's new Android 13 and One UI 5.0 update, currently on a progressive rollout until the end of the year, increasing the impact of the issue. The issue happens with the default Samsung keyboard with the Grammarly integration (aka "Suggest text corrections" aka "Writing assistant") enabled. Any React Native app that involves writing long text in a TextInput seem to be impacted. I am therefore creating this new issue focused solely on the impact of the Samsung keyboard's Grammarly integration on the TextInput component, with a reliable reproducer, as I believe that something can be done at the TextInput level to address it. with the new Android 13 update) is preventing those issues from gaining traction and becoming a high priority. This issue has already been documented here and here but I'm worried that the lack of a reliable reproducer as well as the noise due to other random freeze and crashes in Android (esp. 
When typing a text that is longer than a few lines, the app often hangs and becomes unresponsive, leading to a high rate of ANRs and crashes. There is an issue with React Native's TextInput component when using Samsung's keyboard with the Grammarly integration enabled.
