5. There are 2 solutions to that problem
6. Use the volume down button
10.11.15. Those aren't common on a budget phone for $150 the specs we have right now aren't even common on a $150 phone
16. There's some cable for that I think it's, MHL to HDMI
13. Probably the best selling phone on metro right now
5) I don't consider it a problem. I haven't run out of space yet, with hundreds of apps. But at the same time, from the research I have done, even rooting the phone will not allow apps to be moved.
6) Volume down button does not take me to the Camera from locked screen. The rocker up or down will take a picture once I am in Camera mode. I simply put a camera icon on my lock screen. Not ideal, but better than my Optimus V, and better than most Android phones I have seen anyways. Again, more of a quirk or a wishlist item than a 'problem'.
10.11.15) Duh. Again, doesn't affect performance. This phone is MORE than fast enough with the stats it has. More of a wishlist than complaints. Wouldn't it be cool if, ya know, this thing had a dual quad core yadda yadda yadda...
16) I can use USB to my computer with LG's On Screen Phone program. Very cool. Ultimately, I think DLNA will be the solution. Wireless is always better when it works. Fewer wires is better in the long run.
13) It sucks when a best selling phone isn't popular enough to get lots of accessories. It is a huge advantage of the uber-selling phones like the iPhone and GS3 that they get these cool accessories. And to be honest, even those phones don't have every accessory in the world when you start adding things like enhanced battery packs... Maybe, just maybe, with T-Mobile purchasing MetroPCS, we will get a bit more support, but I won't count on it...
The OP wanted a list of 'catches' on a $150 dollar phone that looked too good to be true. Well, the phone is too good, and it is true. But it doesn't mean the thing is perfect.
Besides, if you compare this phone to a contract plan, who HEAVILY subsidizes the phone with your MUCH HIGHER data plan pricing, the Motion deceptively looks like an inferior value, when in fact, the amortization of this phone quickly pays itself back with the less expensive plans...
