I upgraded our Web Access and Mobile/App software to the latest (10.3) version on the weekend.  I was trying to log into the Laserfiche Mobile App and received the error below.

The maximum string content length quota (8192) has been exceeded while reading XML data.  This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader.

I found the setting that I needed to fix for the Mobile application in the Web Access configuration.  The file that needed to be updated was \Laserfiche\Web Access\Web Files\web.config

The setting was under the APIServiceSoap.

<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />

I had to adjust the maxStringContentLength.  I posted this in case it helps anyone else who might experience this issue.
