Used Emoncms on a Samsung s5 for a long time and no problems, testing a Xaomi redmi 5 phone and it crashes intermittently. The log says:

I am not too concerned but it maybe helpful to the app developer.
The app works with Emonhub on a Pi3 serially fed by 2 x arduinos reading 14 Current Transformers.
