Disabling Pandora's new Bluetooth settings fixes the problem, but HTC/Samsung need to release a fix. The pro version supports USB ELM adapters that use 'Prolific' or 'FTDI' chips. A freeze/hang workaround has been found and is available in the full version in the General Preferences settings.</div><div class="tab-content-content"></div><div class="tab-content-content">Overall, the OBD II engine ECU diagnostics tool is a useful device that provides real-time information about your car's performance and helps keep car repair costs down. The paid version has more features and supports more vehicles and ECU types, making it a worthwhile investment for car enthusiasts and mechanics alike. However, users should be aware of the bug in the HTC Evo 4G and Galaxy Tab and take steps to avoid it.</div>
