I have been using the Nokia 5700 for two months now. This phone was released over here 4 months ago, and yet there happens to be no firmware update for it. It works good and is an excellent phone, but there are certain bugs which are very annoying like:

1) In the log even if u have received a call from a contacts home(thereby showing the home icon which u may have selected during saving the contact) this home icon, appears only when u call from the contacts or when u receive a call. i.e suppose u get a miss call and when u say view, u will see the contact with mobile icon, even if he called from home. This is annoying as suppose u call the contact after viewing the missed call, u call at the persons land line thinking it his is mobile (even when u call him u see the mobile icon though ur calling at his land line).

2) Sometimes the green button stops functioning in the log. i.e if u press the green button to see the log, u see it, but if u call a contact by pressing the green key again it doesn't work. Even if u go in options and select voice call it wont work.

3) Repeated errors saying connection error though the network is fine.
4)Whats up with the camera? Nokia mentions it to be 2 mp but if u use it in a little low lighted conditions, ur pic is screwed with weird colors and poor image quality.

5) The phone restarts automatically (very rare).

6) This isn't a flaw, but i recommend nokia to implement it. When music is on and ur phone is locked, while on loud speaker mode u have to unlock and change the volume. I suggest nokia to allow the volume to be changed even when the phone is locked.

7) This ones very weird. When i keep an alarm and when the alarm rings, i cant snooze or turn it off directly, i have to unlock, and the weird thing is the screen seems to be off!! :S

Beware of Nokia!
