[T-Mobile Samsung Galaxy S7 Edge Guides, News, & Di] seh6183:
Some of this guide may apply to Android 6.0 (Marshmallow) as well. I've honestly forgotten what 6.0 was like since I have been on the 7.0 beta for so long, but some of this is possible on the older software.

So the reason I decided to make this guide was because I recently almost sold my S7 Edge due to poor performance. When I first installed Nougat it was great, but over time the phone got worse and worse. I realize this is an Android thing in general, but it just got to be so annoying that I couldn’t ignore it any longer. I have a vanilla android tablet that flies and when I would switch back to the phone it was almost unbearable. This guide will help out significantly with that issue.

First off you'll want to enable "Developer options". Go to Settings > About device > and then tap on "Build number" 7 times to enable Developer options.

After that go back a page and scroll all the way to the bottom to find Developer options. Click that.

Once in Developer options scroll about 3/4 way down to find three entries that say "animation scale". Change all three entries to "0.5x".

Next we need to go to the Playstore and download an app called "Package Disabler Pro". Yes it's 2 dollars and yes you want/need it.

Before running the app download the .XML file I have attached to this post called "XDA.xml". Now go ahead and open the app and let it load. Next click the three dots in the top right and select "Import from xml". Select the xml file you downloaded from the previous step. This will disable some of the pre-installed apps that you don't need. I encourage you to look through this entire list and click on each item that you would never use, this will permanently disable that app from running or appearing in your app drawer. You can easily undo it at any time by clicking the apps name again (taking the check out of the box). Just to let you know I have 33 additional apps disabled other than the ones in the "XDA.xml" file, I have all kinds of stuff disabled that I don't use; gear vr, gear manager for watches, android pay (I use Samsung pay), S-voice (I used google dictation for everything). I really encourage you to go through and get rid of anything in there that you don't use, it will help the phone out a lot. Once you're done reboot the phone.

When the phone boots up go to the "Device maintenance" section of the settings menu. I at first ignored this section as I felt that it was gimmicky an unnecessary, but then realized that it's actually very useful.

First let’s go to "Performance mode". There is a ton of stuff you can do with this, but I am only going to address one of them. Click on "settings" and then "Screen resolution". Change it to 1920x1080 (FHD). You can always change it back if you really need something such as VR, but most of the time you will not be able to tell that there was a change in resolution.

Next go back to Device maintenance and select "RAM". This menu allows you to close out things from RAM that you don't want running. The problem with this is that Linux (Android) prefers to have apps stay in RAM instead of having to reload them each time you open them, so closing them is kind of counterproductive. Not only that but almost everything that you close from this menu will re-enable itself in the next few minutes anyway. This menu, like the "Battery" section, gives you a look at things which are running that you may not know about. I went through this list and uninstalled apps that I didn't even use so that they weren't just hanging around running without me knowing. A lot of the apps on this list were running and I never even opened them to begin with, that kind of bugs me. I got rid of the ones I could and then used Greenify (more on that in a minute) on the others. Any apps on this list that you for sure never opened, need to be added to Greenify (see next section for instructions) because they are running themselves and using resources.

Now for Greenify. Go to the playstore and download the "Greenify" app and follow the instructions to set it up. It takes a few steps to setup but you only have to do it once. Pay attention as some of the steps are a little tricky and they all must be enabled for the app to function properly. Once installed you will use Greenify to hibernate the apps that you found from the previous section (ram manager) that you don't want awake all the time. Some apps just run themselves without asking you first and sit there consuming battery. I would first decide whether you even need that app to begin with and if you do, then go ahead and Greenify it. Something to note here is that if you Greenify an app that NEEDS to stay awake to work, such as a chat program or music apps, they won't work properly. These apps are easy to spot because they have little blue "gcm" icons next to them, so be careful. To add an app to the "Greenify list" (auto hibernation) just hit the + button in the top right to start adding them.

Once you're done with all that, your phone should be flying. It's not even the same phone anymore really. One thing I want to point out is that the Samsung keyboard on Android 6.0 was trash. It was a completely unusable piece of non-working trash. The auto correct couldn't keep up with any reasonable typing speed, so no words would be corrected at all and you would be left with a mess of a paragraph. I solved that with Swiftkey originally, but for some odd reason it was never blazing fast on this phone. It caught every single mistake, but when you were typing there was just enough lag to kind of throw off your typing speed and it looked like crap. I am happy to say that on Android 7.0 the new Samsung keyboard is the best keyboard I have ever used. They FINALLY got it right after all these years. Honestly all of their keyboards have sucked. They could never seem to get them right, whether it was lag or just plain non-functioning auto correct, it was always something. This one is perfect and if you're using Swiftkey I would uninstall it as it continually reruns itself even when you force close it. It's also a resource hog, so if you don't need it, get rid of it.

There is it, you should be good to go with these small adjustments. A lot of you don't even have 7.0 yet, but when you do at least you will have a head start. There is nothing worse than paying $800 for the latest smartphone only for it to be a laggy mess. Hopefully this helps somewhat with that problem.
