I've gotta say that this thread continues to be my new General Hospital.
But I asked, dozens of pages ago, about people who have these issues getting replacement phones. One person, ONE, responded and said they had gotten a replacement and were no longer having issues. My point was that if you have a problem, don't wait around for 3 months. Yes, it's been 3 months since that screwy update. Be proactive. Take it to a service center. Call tech support and get it documented a few times. Then you get a replacement device. It isn't that difficult. Once you get the replacement you can verify that it doesn't have the newest, and defective, software, because it shouldn't. If it does you're within your rights to refuse it and demand another. You'll get it, or at some point get a GS3 or a Photon Q or whatever, and then deal with the different issues those devices have.
Has HTC done us dirty? Absolutely. They're taking too long to get a fix out. My guess? They figure few people got the update because they pulled it real quick, so they will incorporate the fix into the update they're completing for JB. When you have a finite amount of people to program you prioritize, whether we agree with their priorities or not. What they should have done, minimally, is to re-push the prior OTA, to correct the lag issues' and people would have a less bitter pill to swallow during this protracted wait for JB. They didn't do that. But people who have the lag could have done that themselves by getting a replacement device that isn't loaded with the bad ROM. If you had a blown speaker or a bad 3G radio would you wait for someone to swing by your house and replace the device? No, you'd take it in. Was it your fault it failed? No, but you have to be a little bit proactive. The same thing applies here. Please understand that I am not telling people to "root or shut up". I hate that and believe it to be a completely invalid argument. You buy a device and there's an expectation of performance. If you want more, then root. But if you just want what was advertised, you should get that without rooting.
I'd be curious to know what software version everyone is running, regardless of the contact lag. I'm on 2.13.651.1 710RD. I know BigPuddin got a replacement device within the last couple of weeks so I'm curious what he's running.
