This thread is pointless. The browser lag is common to all the updates, not just manual. The manual update is the exact same file taken from the exact same source as the OTA update, just a different install method. The lag is created by the way the browser renders images and such while moving. It is a known bug.
Ok then, if that is true then it is useless. However, I just thought it was weird that there were people reporting that they had no problem at all. Now, they may not pay attention or care as much as those of us with the bug. No need to get all excited about it. Just looking into the problem more.
I understand the frustration with the bug, but it is a problem with the update, not how it is done. We will just have to wait for Google to fix it, and by the looks of the spam they are getting, it should be soon. Also, bugs do not always affect every unit, hence some of the lag free reports.
