Re: Unstable Internet after 4.3 update.
Same problem. Phone worked fine until 4.3 upgrade. I spent hours on the phone with Verizon support before the bandaid fix to turn off automatic network switching, which stopped phone from disabling my Wi-Fi connection, and now everything appears to work except that I cannot send or receive mms messages. I can browse through my Wi-Fi connection, but messages are somehow blocked. If I turn off Wi-Fi, then messages go fine. Since I've had the phone since Jan 2013, it's now out of warranty and Verizon will do nothing. I see the situation as the software upgrade they recommended and supplied through my contract broke my phone, and they are trying to wash their hands of the matter. Of course they've made it so that you cannot go back to the older version that worked, and they've also made it extremely difficult to unlock the boot loader with 4.3, so rooting is not a good option. I'm wondering what legal rights I, and other Verizon S3 users, who accepted the upgrade to 4.3, have. I'm just about mad enough to talk to a lawyer about the situation.
