speakers for the razer phone 2

My left/top speaker is very low. By it being that speaker in particular, makes it very hard to hear phone conversations, especially since I have a loss of hearing anyway. Although my phone is only 6 months old, it was bought second hand and of course Razer will not honor the warranty left on the phone. So my options are to either get a new speaker and or find out what is causing the low volume from that speaker if it isn't the speaker itself. I have the newest model with android 9 already on it P-MR1-RC003-RZR-190305.3110 If you think re flashing the phone is the problem, then I'll do that. If not, then I need to get the speaker replaced.
