My DS is not working propely !! why ? there are a feew points

1. The L button is sometimes not working and I have to press it really hard ( I actually did a research and that happens to a lot of people and same as with me they didn't drop it or anything like that )

2. I have some problems with wireless conection ( not with the WiFi ) when I want to connect with friends there is communication error though we actually put or DSs near themselves.

3. My touch screen is not working propely because for example when I write something on PictoChat and I touch the screen with my stylus there is supposed to be a dot where I touched the screen but it actually appears about 8- 10 mm under where I touched the screen :( !! I hope you know what I mean in this one.

4. When I press a place near the + pad it clicks. I'm not sure what's wrong white this but did that happen to somebody else maybe in a diffrent part of the DS.

I think that's all. I bought my DS on E-Bay and I don't have any receipt or anything.

P.S. Did any of the things above happened to any other people ?

I only have the DS Lite itself ( ONYX Black) :)

Lego Star Wars 2 :roll:

and Acekard 2 (with about 25 games on it)

I would actually prefer to have a game collection than a flascard with so much games but I don't have so much money thats why i bought Acekard 2
