Please tell us some basic information before asking for help:
Model Name: ASUS ROG Phone 5S Pro
Firmware Version: 31.0810.1226.128
Rooted or not: No
Frequency of Occurrence: Everytime since last firmware
APP Name & APP Version (If your issue relates to the app): Screen Cast
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
Screen Cast connects to my TV and disconnects after a second. I tried connecting other devices to my TV and they connect seamlessly with their casting feature. I already tried clearing all my device cache memory, resetting my router, Smart TV and my phone but still nothing works. This issue started since the last firmware update. It used to work seamlessly on the previous firmware prior to the last two updates. Please check.
