The issue occours after ca. 2 minutes passed (about 1800 times updated). TextViews simply stop to update with no reason, even if accelerometer updates are still working. Our team is working on multithreaded aplication where we have to update some UI control values on UI thread (thats problably the reason why the issue occours). We have spent amount of time trying to figure out what might be the problem and finally we have decited to report it as an issue. I have prepared some sample code based on accelerometer functionality, but in fact the same problem occours when we are trying to use other hadrware devices or sensors (e.g. bluetooth). Here is the link to the sample app repository:
