There is currently nothing in the Mobile Report editor itself that indicates a capacity to order parameters and most graphs have no ordering capabilities
(a couple of the bar charts allow for value or label based chart arrangement - part of the reason I was thrown off here!).
However, one can accomplish sorting from the data sets used in the report. The use of a single data set may cause issues in the parameters... so a standard ORDER BY x, x... approach will only go so far. Using the same values and a different data set, one can accomplish sorting and maintain filtering abilities.
To illustrate, the following query in Mobile Reports gives an oddly sorted State list, since it is actually sorted, in expected SQL fashion, after warehouse and business center lists.
SELECT
WarehouseID
,PostalCode
,City
,County
,State
,BusinessCenter
FROM ...
ORDER BY WarehouseID, BusinessCenter, State
The ordering above solves some parameter list sorting and fixes legend color displays in the report, but doesn't address the State parameter sorting. Another data set with the exact same values contained in State can be used for the parameter, which enables correctly sorted and still functional parameter lists.
SELECT DISTINCT
State
FROM DIM.Geography
ORDER BY State
This resolves consistency of legend location and coloring across the dashboard and solves parameter selection list sorting.

It's recommended to let SSRS recycle periodically so it doesn't hold onto memory it no longer needs, which may be useful to the rest of your server, for example if your SQL Server instance lives on the same server (you wouldn't want SSRS bottlenecking the rest of your SQL Server instance).
If you are able to adjust it to a recycle frequency that happens off-hours that may be best, as noted in this article. Otherwise the correct value is
0to disable it, as you mentioned. For more information, see this other article Adjusting the SSRS service recycle time to zero seconds.
