Maybe someone had same problem. Yesterday I bought Xiaomi Hybrid. Сonnected to Redmi 3, sound works fine, but with remote control is something abnormal. Keys like go in cycles. When I press the volume up once, the volume increases until the end and never ceases to rise. Connected to Samsung Galaxy, all goes well.
