The Sprint Epic 4G Touch has been plagued by a known issue for quite a while now. Not everyone experiences it, but enough do to make it a serious concern for many people, including the folks at Samsung. We're talking about the "LoS" (Loss of Signal) bug -- it mostly happens in areas with spotty coverage and affects both 3G and 4G networks. It's fairly simple to recover, just reboot your phone, but that's clearly not the correct way to go about resolving it. Thankfully, it looks like Samsung and Sprint have a fix in testing to address this, as well as some other minor annoyances that come with every new smartphone.
Epic 4G Touch user kingsway8605 says he currently has the testing patch from Samsung, and he received it after a conversation with a developer who responded to his cries for support. Supposedly the explanation for the bug itself is as follows:
It is isolated to areas with spotty coverage, which is why some don't experience it at all. If you are in 4G and leave 4G coverage, or in 3G coverage and leave 3G coverage, and in the process of sending packets, there is apparently a bug where the phone does not detect this and would just give up after it could no longer talk to the old tower.
This makes sense from an engineering perspective, and if the fellows at Samsung are right this patch should address it. The new OTA is Android 2.3.6, with a baseband of SPD710.10.S.EK02, and a build number of GINGERBREAD.EK02. According to kingsway8605, if this passes initial testing we should see it in December. Developers are already exploring ways to help retrieve the OTA files from the cache partition, so maybe we won't have to wait.
