I have had many Samsung phones over the years, but the Infuse is the first smart phone for me.
I have been seriously considering dumping Samsung/Android OS for a few reasons that I can not attribute necessarily to the phone or OS.
1. I get a TWLANUCHER error about once a week. This causes my phone to overheat (it gets really hot in my pocket) and quickly drain the battery if I do not turn it off and back on. Sometimes even freezes while shutting down when this occurs.
2. I have never been happy with the GPS performance. My kids iphones 4 and 4s always perform better.
3. I have a few apps that seem to forget many of my settings. I have contacted the programmers and the typical answer is that it is either an OS or Samsung issue.
Based on these, I am leaning to an iphone next time. My kids never have a problem with them, and the cost is equivalent to a top model Samsung.
#1 #2 are not normal behaviors with any phone. You may have defective firmware. Try doing a factory reset, and if that doesn't solve the problem, try and have AT&T replace your phone under warranty. The original Galaxy S series were known to have GPS issues. It is possible that the Infuse has the same GPS chip.
There may also be apps installed on your phone that are causing the TWLauncher errors. As much as my phone has problems with rebooting, I have almost never gotten any TWLauncher errors; the same applied to my first Infuse.
Please give Samsung and Android another chance. Samsung makes great phones, and Android is implied to be eons ahead of iOS. Take a look at wicked4u2c's YouTube channel featuring Android vs. iOS: (Part 1)

Remember that even though there are great phones out there, there is no perfect phone. No phone is without its own set of problems. Even the iPhone 4S has problems, like Bluetooth issues, earpiece issues, and battery drain issues, all of which were fixed by Apple.
Oh, and speaking of Bluetooth, you can't do Bluetooth file transfers on an iPhone. Neither can you use the iPhone as an external hard drive.
Keep in mind that the price of the top Samsung Android phone and an iPhone may be equivalent to each other, but that you are making a choice between virtually unlimited customizations and user freedom vs. simplicity and strict limitations on how you use your phone.
The reason the issues on the iPhone 4S were fixed by Apple so quickly as compared to issues with the Infuse is all based on flagship status. The Infuse is
not a flagship phone. If you want more information on this, contact yohannie or see the other posts that yohannie made regarding the Infuse. You might have much better luck using a flagship phone, so try to get your hands on the Galaxy S3 (which, by the way, has a barometer that helps with GPS signal lock) and play with it for a while. I've done exactly that with the floor models, and you won't believe how much better it is compared to the Infuse, which stays in my pocket untouched for the whole time I explore the Galaxy S3. It is dubbed by some tech sites as the "iPhone killer."
