3G stopped working on galaxy s2 after encryption
Answered

Phone was working great for about a month, I had to encrypt device to use my phone for work. After encryption, 3G stopped working. There is not even a 3G icon anymore. Also no longer recieving picture messages(just says downloading and the picture never come through) and my 4G icon is still there but never has 4G service.

  • Update: I have decrypted the phone, and all data service returned to normal. But when I encrypt it again it goes away again. Please help, I need to have my phone encrypted to use for work.

  • Strangely enough, this sometimes has to do with the Wifi sleep settings. Can you go into Settings -> Wireless & networks -> Wi-Fi then press the Menu button and select Advanced. Select "Keep Wi-Fi on during sleep" and make sure it's set to Always (if it's already on that, select something else then go back and change it to Always again). You'll then need to reboot the phone. Hopefully that does it, but definitely let us know if it doesn't.

  • Did you do the adjustments before or after re-encrypting?

    I'm afraid I don't have much insight to offer you here. I have a Galaxy 2 myself, but have never played around with this feature. If I had to guess, I'd say that the credentials that your phone uses to access the network can't be read when all the data on the device is encrypted, however, that's just a guess.

    I'd suggest checking around on Google, and if you're intent on using your phone while encrypted, hopefully you'll find some more info there.

  • XDA developers forum would be a good choice to try.

  • "if you're intent on using your phone while encrypted, hopefully you'll find some more info"  -- The sole purpose for getting the phone and switching to TING was to use it for work, and it needs to be encrypted for that. So, unfortunately,  I would say I am more obligated to use it encrypted than intent on it. My coworker has the same phone on the AT&T network and has had no issues with encrypting it. I'm not very tech savy so checking around on google and developer forums...I wouldn't even know where to start.

    A quick Google search turned up issues with encryption on the Epic Touch. It appears that at one point the option was disabled and removed during a software update.  http://community.sprint.com/baw/thread/82114 Since there appears to have been a very recent software update it is possible that the option has been restored. The update may in fact still be going on and it is possible you don't yet have it yet. The software options available on a phone, including the option to encrypt are totally up to Sprint in this case. Ting will have no control of it's function. I would post your issue on the Sprint Community forums. http://community.sprint.com

  • Nancy, given what you've said, here's some advice I can give based on what I could find. 

    I also want to be clear both to you and to anyone else reading this that because this device came from Sprint and not us, the assistance we can provide is a bit limited. For instance, issuing you a replacement isn't an option.

    In terms of what I've been able to find online, at least one Sprint user was having this same issue, and found that it was corrected after they purchased a new battery. This suggests that the problem was power related, with encryption as only a secondary issue.

    While there's no guarantee this will do it, there are plenty of places to buy replacement batteries for pretty cheap such as Amazon or eBay.

    Another thing that you could try would be a complete a hard reset, and set the phone back to default settings.

    While neither this or the battery replacement are guaranteed to fix the issue, this is the best advice I can give considering that you've already decrypted and re-encrypted the data, and found you were still having the same issue.

  • Thanks for looking into it, I'll check out the sprint forum links and try the hard reset and new battery. Hopefully that helps. Thanks again for taking the time to look into it and respond. Even though no definite solution, I do appreciate your time. I'll update if/when it is resolved, in case anyone else has the same issue in the future.

  • Nancy, just curious if you had any success, we are having the exact same issue on the S2.
