New Redmi 2, Bluetooth Turns Off Automatically (solved In New Release)

[kiswum]

Device: Xiaomi Redmi 2 WCDMA 1GB version
ROM: 5.1.23 (Language English)

Problem: Bluetooth shutsdown turns off without a reason.
I keep my Bluetooth running in the background on every phone I have. I use it to connect to my car radio/Headunit or to my Wireless headset. I noticed several times that my Bluetooth has been turned off by itselve. I don't have a app running which uses location profiles like: Llama.
There are no FC messages or other things that show that Bluetooth stopped working.

Sometimes it shutsdown after 10 hours, sometimes I noticed that it was still running after 20 hours.
I have tested it with the Battery Saving mode and Performance mode.
During these tests, I haven't turned off my phone.

I don't know many people with a Redmi 2, please let me know if you can verify this bug.
