    Shortly after buying this phone I noticed two odd problems:

    1) if you've been connected to wi-fi for a while, it loses 4G until you reboot it.
    2) wifi automatically turns itself on even after you turn it off.

    Those two things are almost unbelievably annoying, especially with QWERTY phones regularly disappearing from the market. After several months of patience I finally got around to rooting it and looking into solving the problem. I would call this solved, except it's only been a day, and I haven't roamed at all (snowstorm) so I can't say 100% for sure.

    I long suspected the problem involves "Connections Optimizer" but I found that merely disabling it didn't help-- in fact it didn't seem to make any difference. Also, switching from LTE/CDMA to just CDMA network preference didn't help. Connections Optimizer seems to be a buggy piece of, uh, software written by Sprint and/or Boost that drops 4G in favor of WiFi. Probably so that you don't tie up their data service with, well, the data you're paying them for. Buggy or not, it's worthless.

    Here's how I got rid of it, apparently solving the problem:

    - root the phone. I have the latest firmware (LS860ZV8). I used motochopper ( hex a mob .com/how-to-root/motochopper-method/ )
    - install Titanium Backup Root from the Google Play store.
    - remove Connections Optimizer (the version I had was 1.3.639 in case you care).

    I also removed some bloatware with no problems:
    Boost Zone 4.4.25 -- useless ad delivery garbage bloatware crap I despise. I'm sure Sprint has an equivalent.
    Qualcomm Enhanced Location Service -- I don't know what it does and don't care.
    Shopper 2.4.2 -- this might be a Google thing...
    Sprint Installer 2.2.2 -- I'm not even ON Sprint

    I will update this if I discover I wasn't right.

    Oh, don't forget you should back up everything with Titanium before doing anything.

    Also I was able to uninstall Mobile ID without problems.

    and remember to go into preferences then backup location hit the back key and slect external_sd and create a new folder, otherwise if your phone crashes so does your back up because of that internal sd crap

    I'm no longer convinced my fix actually worked. It seemed to help, but not 100% of the time, and it's very hard to verify since there is no consistent way to cause it to happen. I have had to reboot a couple times to restore data connectivity when Wi-Fi is not available.

    I'm not sure the problem is the phone. I think the problem may be that Boost Mobile 4G service sucks. I didn't have this problem with my previous phone (also on Boost).

    Just out of curiosity, is anyone else having the same problem? I only found one person complaining of it (to Sprint, IIRC) on the Internet. I suppose it might be a dud phone.

    i had the problem but it seemed to have gone away, have you tried going into settings and updating your PRL and profile?

    sorry on all slow replies and whatnot i'm not as active on the forum like i used to be because of the lack of development on this phone.

    Sorry to respond so late. Not on here much. As this model phone doesn't seem to be very popular. Try ging into Setting > Wireless & Networks > More > Mobile Networks and disable Connections Optimizer. As everytime the phone reboots or a battery pull is done. It is automatically enabled. An always tries to pull wifi if one is local.
