Glad I could help.
Just be a bit careful about the details in the database. This data is generated by users who use the "Sensor DB" experiment (white entry at the bottom of the main menu in phyphox) and we have no way to verify it. The frequency should be accurate, but it does not mean that you get "good data" at that rate. The standard deviation depends on whether the users actually did not touch the phone while testing. Phyphox tries to prevent submission if it does not get a more or less constant standard deviation, but there is only so much we can check and sometimes drifting messes up the noise estimate. So, unless there is a bit more statistics than the report of a single user, it is hard to compare the standard deviation across devices.
