I've been searching on google and reading up on this issue for a while, and I still haven't found any definitive answers on it. Various threads have discussed solutions but nothing proves to work, even a complete reset of the phone.
I would like to ask anyone who has not already done so to add a star to this topic, so that it will get some attention of the developers. I believe this issue takes away some of the enjoyment of using this otherwise great device.
Issue 5286 - android - Browser lags when scrolling after 2.0.1 Update on Motorola DROID - Project Hosting on Google Code
The choppy scrolling or "lag" is a nuisance. Coming from an iPhone I may be a little more bothered by this, because all the animations and scrolling on the iPhone 3GS were butter-smooth.
On my droid, even scrolling the home screens left and right exhibits a slow refresh rate, or choppy feel to it. I have simplified my home screens by removing all widgets, tweaked all the settings I can based on recommendations in various threads I have read. No marked improvements.
The browser is terrible. Scrolling around is very choppy. I've tried all different kinds of resets, clearing the caches, etc. Nothing works. Stock browser, Dolphin - doesn't matter. This is some kind of issue with the graphical performance of the OS.
Many people claim they don't see any lag or choppy scrolling effect. I think many of these poeple need to pick up an iPhone and play around with that for a while to see how much more responsive the screen is to input, and how much more smoothly everything slides around without a stutter, chop, lag, or whatever you want to call it. Once you see how it should be, you will see what the issue with the droid is.
