im not sure if you notice this but on marshmallow devices the bearer settings have lots of options unlike in lollipop and kitkat which only has 3 options unspecified,lte,ehrpd.. in marshmallow it has uspecified,lte,hspap,hsupa,edge,umts,hsdpa,hspa,gprs,evdo_A,B,and C i tweaked mine by ticking all except unspecified,lte,ehrpd,1xRTT,IS95B IS95A
you can chech lte if you connection is lte 4g but if you only on 3g dont check it just give you battery drain hspap hsupa hspa hsdpa umts and evdos abc those settings speed up download and upload as well as connectivity..while gprs gives you better signal..
this is open for rooted and non rooted phones but i think roted phones can benefit from these tweaks happy modding guys..
