I wasn't quite blown away by the Bionic neither, and I entertained the idea of returning it as well...mainly due to being able to see that grid everyone mentions on some screens and images, battery life being somewhat dismal, and auto focus being unstable on the camera, and thus far no faster really compared to my TBolt (rooted btw) on 4G...
that being said, I rethought all things and decided to keep it anyways because of the following reasons...
*I noticed that while there is the grid effect on some stuff, there is also incredibly crisp image qualities at times also...like the bootanimation eye which is basically HD quality with no grid effect that I could make out at all, and some of the pics that I've taken and I was able to get the auto focus just right turned out very sharp afterall..that and the fact that I tested a video that I encoded from Bluray m2ts to an x264 encoded MP4 (full movie down to 1.13 GBs) and watched on three separate players, all with differing results. Rock Player had that grid effect very evident, but the stock player and Mobo Player did not, and to be abe to make out the smoke on a video is truly HD...so I'm thinking the grid effect is software coontrolled and can be completely overridden eventually ...jmho
*While the battery life was dismnal at best early on, it seems to be getting better with every full charge, Been off the charger for about two hours and it's now only down to 90%...and that's with all sync fully auto including Google location services and GPS fully auto as well, watched the HD vid for several minutes, browsed the net a bit, and have had a live wallpaper the whole time... not bad ....and just imagine once custom kernels can be implemented!...that's one thing that made me lean towards keeping the Bionic...eventual full unlocked bootloader, I think it's only a matter of time really...
*the camera issues seem directly related to it's crappy auto focus, becuse I see it trying to focus and the same image pic can be taken and one turns out as crisp as HD and the very next turns out like an old pic taken with a poloroid camera...lmao...so I truly think that if they were to release an updated camera apk it'll turn out much, much better...
*and 4G..... it's always going to be as fast as the area's network will allow it, so the fact that my Bionic is always as fast on 4G as my 'Rooted' TBolt was, well that's a plus since it always keeps that 4G signal whereas the TBolt would lose the signal once every so often...that coupled with when the area 4G gets better, well it's only going to get better since I am sure the Bionic can go much faster, as fast as the network will allow it down the line... very promising imho...
Well there you have it...why 'I am keeping my Bionic'...
