Unstable hardware

your device's configuration options and / or disable such behaviour in applications called 'task killers', it could be vendor or OS version specific functionality, please
refer to your device's manual or your task killing applications for specific instructions how to do it
- automatic monitoring in the background - some smartphones and other devices after many hours of trying to reconnect to Bluetooth ELM327 device will fail to operate
the Bluetooth subsystem completly, if this happen no new connection will be possible to be established with ELM327 or other Bluetooth devices, to solve the issue the
smartphone complete reboot is required, to prevent this from happening in the future you may try to extend the connection attempt delay to at least 180 seconds or even more
and futuremore you may shutdown the DPF Info application each time you don't need it; I don't know what causes this and don't know how to resolve that yet
- automatic startup on phone boot - some smartphones and other devices may require additional setup to allow DPF Info application to be started right after Android's
boot, it could be vendor or OS version specific functionality, please refer to your device's manual for specific instructions how to do it
- text to speech capabilities - currently only ENGLISH language is supported by defalut and your device has to provide text to speech service to be used by DPF Info
application - it could be vendor or OS version specific functionality
