    i have some thoughts on what happened. I've explained some in more detail than needed for expert users since many ordinary people are looking for solutions to this issue.

    1. When Sprint sent the OTA upgrade to ICS, the process did not clear the dalvik cache. This is the place where applications are compiled as a one time event. If the process had cleared the dalvik cache the reboot would have taken a lot longer than it did after the update. I believe the lagginess, the rapidly discharging battery, the nonfunctioning buttons etc are caused by the fact that executables compiled for Android 2.3.6 are now running in a ICS environment.

    2. All the other "solutions" mentioned in many other threads "turning wifi on/off, uninstalling apps, removing widgets, charging battery" are all red herrings

    3. Doing a factory reset of your phone clears and rebuilds the dalvik cache. I believe this recompiles the internal apps and processes into versions compatilble with the ICS update. Therefore this seems to solve the problem

    4. There are two ways to clear the dalvik cache a) do a "factory reset" to the phone b) root the phone and clear the dalvik cache. Since the b) probably means reinstalling everything anyway, you are better off doing a) because doing b) for many non android expert people will result in a bricked phone

    5. Corollary of 4 is that you are going to spend 6-8 hours reconfiguring your phone to the way it was, probably losing some data along the way

    6. Sprint is solely responsible for not including clearing the dalvik cache and forcing a recompilation and repopulation of the dalvik cache as part of the OTA process.

    7. I believe that this bug is going to affect everyone who updates to ICS until Sprint includes the processes I have mentioned in 6.

    8. As for the people who have already been affected (which is everyone who updated), I hope Sprint pushes out a second update that clears the dalvik cache.

    I am very disappointed that whoever was in charge of the ICS update @Sprint seems to not have done even basic beta testing.
    Nicely written and I totally agree. But even after spending the 6-8 hours, I'm still not happy. Bluetooth is a joke now. My phone actually crashed on me. I've never had it crash on me before.

    Would doing the update by this method: [ODIN][TAR] SPH-D710.FF18_CL663858 (FF18 Modem/Kernel/ROM - Full Restore - Rooted) - xda-developers have the same issue, as far as the dalvik cache? Would restoring the call log and SMS from MyBackup Root after doing a factory reset cause a problem?

    I want to sincerely thank Dark Knight 2 for his excellent and encouraging post! This forum thread is the sole reason I decided to finally pull the trigger and update ICS, and I'm glad I did. Here is a summary of my experience...

    Before doing the manual update on Friday, I first did a Factory Reset (including wiping USB storage). Then, after finalizing the ICS manual update, I did another full Factory Reset, before installing anything. After that, I began re-installing and re-configuring my ET4G.

    It's now Sunday night and I have to say that I am EXTREMELY pleased and very pleasantly surprised how smooth the phone is performing and how well everything is working. Virtually all issues I was experiencing under GB have not revealed themselves as yet in ICS. Here are a few items have that have improved noticeably since my manual update...

    - GPS getting instant position fix
    - Android OS resource draw not occurring
    - Battery life seems better
    - WiFi performance seems better
    - UI seems smoother, faster, better
    - Much more!

    In summary, I highly recommend CAREFULLY installing the manual ET4G ICS update, but ONLY if you're willing to take the time to do a FULL FACTORY RESET! As stated above, I actually reset twice, once before applying the update, then again after. I can't say for sure that the pre-Update reset made a difference (I personally think it did), but it certainly didn't hurt.

    I hope this info helps those interested in proceeding. I was apprehensive to update after seeing all the negative info, but figured I'd give it a shot, and I'm VERY HAPPY that I did.

    Good Luck!

    OK, so I went ahead and did the factory reset, and Holy Crap, What a Difference!!! I'm over 4 hours into my day, pretty typical usage pattern and my battery is sitting at 80%!!! I've never seen that before. Definitely worth the pain from the reset. Thanks for the advice.

    If I do a factory reset, are the apps & phone settings/preferences the only things I'll have to reconfigure? My main issues are the with the wifi sleeping & losing the connection (have to turn the wifi off then on again & it gets annoying where gingerbread never did that).

    Haven't yet, I'm on the verge though! I'll probably get around to it when I have several hours to spend reconfiguring things.

    Won't pair with SYNC any more.
    No Pandora on 3G. Only WiFi.
    Battery usage, (I will see how it is after Lookout is uninstalled)
    It's very slow to react sometimes.
    The android OS is ALWAYS the first on the list of battery usage.
    Even with me using Words with friends, facebook, drawsomething. But I turn all notifications off for all those apps. I consistantly get searching for GPS as well.
    Phone will reboot for no reason. Today the battery went from 44% to 4%, after it locked up and came back on it's own. I let it sit, then plugged it in, about 30 min later it went back to 40%. Its just not stable. This phone used to be rock solid. Never a glitch. Now I can't trust it. Hate it! Wish I never would have taken the update.
    I want my Mass USB storage device back.
    Just not happy.
    Sick of messing with it. SHould not have to do all this crap that I've had to do. No I'm not ready to drink the Kool Aide and buy an Iphone. I love droid, just a little upset.

    Currently my Android OS is at 65%. Screen is at 20%. Android system is at 9%. This is after 5 hours on battery and my battery is down to 38%. The lowest on the list is Phone idle 2%

    I'd show you a screen shot, but to try and surf this forum from phone will kill it!

    So I did the factory reset and while things seem to be a little smoother, it still doesn't fix the intermittent wifi issue at all. Actually wifi is slower on ics than gingerbread.

    I hope sprint comes up with an update quickly because it sucks to have to turn wifi off/on again all the time after the phone sleeps.

    Quick update, I saw other thread recommend formatting SD card to improve battery life. So I did. I am at 13.5 hours, 45% battery remaining.

    I had that issue until I found that the ICS Update set it that way!
    I went to SETTINGS>WIFI> then hit the MENU button to bring up the ADVANCED setting box. Hit that and selected "Keep WiFi on during Sleep" and set it to NEVER or ONLY WHEN PLUGGED IN. Otherwise it was on absolutely full time.

    WiFi still kills the battery worse than GB and I now turn it on and off as needed but at least it isn't killing the phone when it was just asleep in my pocket!

    My daughter is now getting the update message and I told he not to do it.. but it is one persistent message! I am now considering rooting my phone but no way I can root hers since she doesn't live near here and would have no one to turn to if she had issues and sprint would not like her dropping into the store with a rooted phone, me thinks.
