I dunno about the Lenovo phone u are using, but the Tempotec Sonata HD Pro has almost the same sound quality as my desktop setup (Khadas tone board -> Fiio A3 Amp), superb sound quality for the price of $30 - 40ish USD. For those using LG quad dacs I'm not sure if Sonata HD Pro is on par, but it is better than my samsung note 5 in terms of dynamics, clarity and having a dark black background.
The Sonata HD Pro is probably the Hidizs S8 OEM version and is the same internally and on measurements done on other audio sites. Hidizs S8 is rated very highly here on audioscience review:

There's a table of DACs with measurements compared here (look at the yellow line which is Hidizs S8 AKA Tempotec Sonata HD Pro):
Measurements are of course one thing, whether we can hear the difference is another story, but it supposedly is better in measurements than some famous brand names above.
