Probably, some examples include the ancient old Mi Note HiFi which has a very heavy emphasis on the 3.5mm output being great
as well as some LG Phones with their signature Quad DAC
but it's not a topic that's discussed much these days since phones with 3.5mm jacks are already a rarity, so most people are happy that there even is a port
there is no "brand" that has best jack since little attention is being paid to them
unless you get a dedicated android media player from an audio focused brand like Fiio
the better option is to get a cheap USB-C to Headphone Jack adapter with DAC chip inside
some examples include CX31993 PRO or Apple's USB-C to Heaphone Jack adapter or VE Abigial Pro
roughly rm50 range
and it only goes up
some more expensive ones like Fiio KA17 are also good
there is a local FB group called DongleMadness that discusses those
Thanks for the quick response. I am referring more to phones which have good DAC inside such as the LG with Quad DAC which you have mentioned, not so much about best earphone jack. The LG is more or less dead I think, I've owned the LG V20 before, bought it because of the Quad DAC but it was replaced with a Huawei after I lost the phone about 3 years ago.
Noted on USB to 3.5mm jack adapter which can be used with phones without the 3.5mm earphone jack. In this sense, is there any modern phones without 3.5mm headphone jack which have good internal DAC / great sound quality?
My primary focus is quality of camera, sound quality from earphones and overall usability ie. long battery hours. So far I've shortlisted Oppo Find N6 Pro and Vivo X100 Pro but there is no mention about any hifi DAC inside these phones.
