chanchan05,
yeah I know what you are saying, I have a background with industrial electronic equipment and there's always lemons. But in the case of these phones, online I see more bad than good, but I suppose that's the nature of how forums work, typically being more bad than good. That's why I don't understand why there are so many people having a great time with them, calling people "TROLLS", in these forums if they are supposedly NOT having issues. If took a step back they'd understand what they are doing is in fact trolling, if you don't have anything constructive to say then WHY ARE YOU HERE??
BTW it was a $30 piece of rubbish too.
Anyway I may have sorted some of my issues as of last night.
When I bought the phone I was sold an EFM glass screen protector with it, it's one of the useless ones that does not cover the full screen. Initially I thought it was just an annoyance not something that would cause crashes but, looks like it was the issue. I suppose I could potentially carry out hundreds of touches to the screen in one swipe if the screen protector is too thick or not made of the right material. Which could certainly count for crashes in some cases and laggy scrolling etc. I tried 4 different launchers that all crashed within hours of installing them which is why I was really starting to worry as I knew it wasn't related to the infamous touchwiz.
Anyway I have not had a "real" issue since I removed the rubbish screen protector, still a little lag but the lag is in the website not the phone I believe.
So hopefully someone finds this amongst all the TROLLING and benefits from it.
