@chaosrecords , my friend, sorry to revive an old thread, but I figured that your expertise would be well received

As of now, Xposed doesn't work with Lollipop on the Note 3, and it'll be awhile before we have even a beta for it - so, I was wondering if you knew anything about changing DPI settings for individual apps without the use of XPosed?
Thank you, man
Unfortunately I do not.. yet.. but havent really tried
There is a team working on Xposed for lollipop, however last i checked it didnt work with touchwiz roms But it may work with an AOSP Rom.
Since Lollipop came out I went to a stock rom rooted and just left the dpi alone since its tolerable with the note 4s native resolution being so high I have the camera sound menu muted, and the hotspot activated and adblocker and some bloat i manually removed, and it works for me.
Ive been kind of out of the loop lately because in Feb Snapchat decided to put C&D on everyone that developed add-ins to the app, so I have just been using my note for calls and chrome and started using my iPad ALOT more.
There hasnt been a big push for Note 4 Development compared to the note 3. Im near the end of the road with Samsung, they take one step forwards and two steps back. Would be nice if we saw a waterproof note 5 that didnt look like an iphone and didn't ditch the micro sd slot/ battery, but i have a feeling Samsung will do exactly what it did on the s6 to the Note 5 and that will be the nail in the coffin for me..Who knows =)
I am going to download some of these ported aosp roms and start playing around if i find anything useful ill be sure to post back here.
The only thing that keeps me on touchwiz is the camera.. note 4 camera is superior, but samsung keeps dumbing things down to "Auto" cant even take a macro shot anymore, so might as well go aosp.
