Bluetooth connects but no sound and videos freeze

Hello

Recently my Razer phone bluetooth stoped working, things i noticed is that when i connect my phone to a speaker or headphones there is no sound and if i try to play a video it’s really slow, nearly frozen, happens if im connected to wifi, mobile data and even with offline videos, occasionaly it works if i turn it off and on quite a few times in a row, no updates were made to the phone since it’s old, unsure what the problem is.

Steps i already taken:

• Hard reset
• clear bluetooth cache and data
• factory reset
