[Q] Problem, Stuck in Black screen doesn't wake up

---

Hello!

Well... I have this phone since yesterday... I plugged to the computer with Kies, and well, a update was available... now the phone have Froyo and the aesthetics changed completely, it looks awesome.

But, the phone have this ANNOYING problem that, after using it... like 5~10 minutes of no activity, when I try to use the phone again it doesnt work... doesn't respond to any button, I have to take off the battery in order to restart it and that over and over again...

I've realized also that this happens when I'm using wifi, if I left the phone with wifi on this happens, without wifi seems to work fine.

Somebody have any clue what could be? there's little information about this issue in the internet...

I think I'm going to return it but I want to try everything I can do (without voiding the warranty) since the phone was perfect for what I wanted.

Thanks in advance!

Hey. I got the same problem here. It only happened a few times when I just had froyo that came stock on my galaxy 5 but I recently installed cyanogenmod 7 and now its happening everytime I put my phone down.
So I'm guessing it may be directly related to what rom is installed? I've heard about it happening a bit to people who have 2.1 installed to.

I dont know too much but it seems the only fix is to take out battery and turn on.

Sorry I can't help more. I hope somebody knows a bit more than me on this.

Think this is called something like the 'wifi sleep of death', something to do with the rom. i'd try change the rom and see if it still occurs

Thanks for the hints tho!, but I returned the phone... it seems that is a bug related to the update of the phone, since I know that with the out of the box 2.1 version it doesn't have that issue...

You know, the mobile carriers also do weird stuff to the roms... -__-
