[Samsung Epic 4G Touch] geolemon:
I've updated from a rooted stock GB ROM to the ICS update. I'm surprised this is the update Sprint/Samsung released for the phone. The GB ROM was stable and clean, this one seems to have some issues... primarily:

1) Battery life is 6-7 hours LESS - at least.

One thing I've noticed here is that "Android OS" is using about half of the battery. Previously (and confirmed with my buddy with his GSIII), this only used about 4% or 5% . I suspect this is a culprit. :eek:

I've attached some screenshots showing this.

Almost no use of the phone all day, I was at work - some light texting later in the day. So little that SMS or GoSMS don't even appear on the chart.

2) Swype keyboard issues.

Yes, you can clear your app cache for swype and get it to work. However, you apparently can't get copy/paste/select word/select all to work.

When you click on text and click the little handle that appears, only a small box appears above, which is where the menu should be for copy/paste/select word/select all should be. At least I think that's the options - from memory, since I don't have them any more. :crying:

I've attached a screenshot showing this.

[EDIT: This is a usage issue - I consider this more difficult than before, and quirky in that it doesn't always work, but generally if you press and hold text, it'll open an edit panel where the notification bar is. Sometimes double-clicking works.]

3) Signal issues.

Again using the Battery screen - I'm seeing some very odd patterns both with carrier data signal and wifi. Previously, carrier signal was an uninterrupted line, of varying shades of green that corresopnded to signal strength. Now, when I look at this line, there's some very good sized breaks in it. That's a sharp contrast to how it used to be.

I know that searching for signal can use battery - maybe an issue with the radio? modem?

Same for wifi - I used to have a setting for "wifi off when screen off". Now it's gone, or changed - I see a "wifi on while sleep" that is checked. Despite this setting remaining constant, I see periods where that seems to be happening (later), but also a long period where wifi is active despite the screen off.

I've attached a screenshot showing this. See the "mobile network signal" line in the plot.

4) General, observed quirkiness.

Screen not being as responsive. When I press the power button on my phone now, it takes 2 or 4 seconds for the screen to activate. Touching the screen sometimes results in a very laggy response... enough time to poke the screen a second time. Skippy/unsmooth screen transitions in some cases. I've had GoSMS vanish on me a couple times and I had to relaunch it. Other apps become unresponsive and I've had to hit the home button repeatedly - sometimes 10-15 seconds before the phone comes back to the home screen and out of that app.

The screen captures were taken throughout the day - the times appear on them.

I've also attached two BetterBatteryStats dump files - one of them I had all options checked, the other just the defaults. They were taken about the same time, and about the same time I took the 8 hour screen cap.

If it matters, I'm using Go Launcher EX, it's still my stock launcher. I'm noticing not many people on ICS using it - are there known problems?

This is frustrating to me - I use this phone for work, I came off an AOKP ROM to get back on a stock ROM, for two things:

1) stock stability and battery life.

2) the Exchange account options for sync scheduling (on peak/off peak schedules for sync) that only seem to be in the stock ROM.

[EDIT: I performed a full factory wipe several days ago, and reinstalled all apps via market, and still are experiencing these exact symptoms. No improvement. May restore my nandroid from before the wipe just to gain back a few things I inadvertently lost as this didn't resolve anything.]

Accordingly, I'd like to see this ROM working. Any thoughts on these? :confused:

Anyone else observing these symptoms, relative to the stock GB rom?
