Re: This lag is unfreakingbelievable
A few things before I begin to outline my situation:
Tmobile Note 7 user. I always keep an android and iOS device on me. I have no real preference. Am coming from the S7 Edge (which is easily my favorite android device to date).
That said, out of the box and for the first few days I was experiencing severe lag - specifically the animations. Frame rate drops/stutters as you navigate the OS. Was massively frustrating considering the S7 Edge has provided such a fluid experience. Especially in comparison. The S7 Edge was the first Samsung device that I felt didnt suffer from what others refer to as typical Samsung "jank". It was definitely back on my note. Hitting the home button saw a noticeable delay before action was taken, open and closing apps saw frame rate drops, etc. So I started to work through what might be causing it.
I backed up using sidesync from my S7 Edge. Maybe something was slightly corrupted in that transfer? So performed a hard reset and set up as a fresh device - not even pulling down the samsung cloud data.
Problem persisted.
So then I started taking a deep dive into the settings and disabling even more apps that I know I wouldnt use. At this point, its purring along quite well and has been for a solid 24 hours. Here's what I did:
1. Disabled preloaded amazon, every T-Mobile preinstalled app thats possible, Facebook, Lookout, S Voice, Samsung+
2. Turned off Wi-Fi Calling
3. The "T-Mobile" app doesnt allow for disabling. But I turned off everything that it could possibly do/have access to within the app settings. Location, send SMS, make calls, etc. Everything.
4. Turned off smart stay, smart capture, palm swipe to capture, direct call, smart alert
I'm missing some other small tweaks that I dont remember at the moment, but the two things I want to point out that I think made the biggest difference (and also have seemingly increased battery life by a significant amount) is disabling Samsung+ and shutting off everything within the T-Mobile app. And potentially wi-fi calling. Combined with not backing up from an old device (a common problem on iOS too).
Samsung+ appears to be eating up a ton of system resources considering how much stuff its monitoring. I found a process "Help" running constantly that appears to have been tied up in the processes for Samsung+. I shut off everything within the Tmobile app at the same time as disabling Samsung+ so it might not have been an issue - but it did seem to be grabbing my location enough to show up in the list of recent apps to have requested location data. I just shut off wi-fi calling this more as further testing.
As mentioned, not only has my battery life significantly improved, but the fluidity around the phone is pretty night and day. I was very close to returning and just sticking with my S7 Edge for now. Or until Samsung issued an update. But if these changes continue to work/help, then I'll be keeping it. This is easily the nicest hardware ever produced of any phone - iPhone or otherwise. Tons to love about the device. But a stuttery OS experience is a major deal killer for me. Hopefully these changes continue to help!
