[AUX PROBLEM][XPERIA Z5] Unstable connection

[Sony_select_err]

Well I don't know how to explain my problem ..but I have an AUX cable , when I insert it in my phone's jack I get unstable headset notifications .. like this : connected .. disconnected ..connected .. disconnected ( for serval  times ), after a few secs it becomes stable and connected , but when I play songs with high bass and max volume it returns to disconnect and connect again the sound stops and never could play it again ! first I thought it is the cable problem but I tried on others phone like Z3c and it was working like a charm .. I can also confirm that it is not a hardware problem in my phone cause my earphones are working perfectly .. so where does the problem came from and how to fix it ? thanks for reading and I hope someone well give me a solution 

- My device : XZ5 dual ( E6633 ) 

- Firmware : MM .253

I had a similar issue but the problem was a faulty AUX cable, it'll be wise to test a new AUX cable.

Tested on : Z2 / Ipad mini / my laptop all are working fine with no issues and super stable connection 😕

Yeah, I had a similar issue, also, make sure that there's no dirt, grime or anything inside the 3.5mm connector
