We have complaints that people can't drive their car on the motor way. They can't get on the second lane...
More or less this is your problem description.
For people to be able to help you, provide as much information as possible. For example:
Limesurvey Version?
Which template is used? Is it a untouched template that comes with Limesurvey or has it been customized?
Does this happen to all Android users? If not, what versions of Android are impacted?
Do you have an example of the survey? Can you provide us with a link?
What question types are causing the problem?
What does "first category" mean?
etc.
