Hello my nokia 6303 has a screen problem,it goes very dim/dark...i switch it off then it wont restart for hours/days,then it lights up perfect,phone is 11 months old...could it be the battery?...thank you, hughie,ireland.

Generating codes won't provide you accurate unlock codes. Trying to unlock with inaccurate unlock codes for more than a limited time may lead to hard lock of your phone. Then your phone may become unusable. So it is wise to get the accurate unlock code from any trustworthy online site. For example you can get accurate unlock code for a Nokia 6303C from www.mobileunlocksolutions.com/nokia-6303-classic/rs1wp9/ at most affordable cost. Here are the steps for unlocking a Nokia 6303 C,
1 - Switch on your Nokia 6303 Classic without any sim card.
2 - Don't bother as to what is displayed on your Nokia 6303 Classic.
3 - Compose #pw+CODE+1#.
4 - The Nokia 6303 Classic would then display the message "SIM Restriction Off" and will be unlocked!

Note :For Nokia 6303 Classic mobile phones locked to the network Fido or Rogers in Canada follow these instructions :
1 - Switch on your Nokia 6303 Classic without any sim card.
2 - Don't bother as to what is displayed on your Nokia 6303 Classic.
3 - Compose #pw+CODE+7#.
4 - The Nokia 6303 Classic would then display the message "SIM Restriction Off" and will be unlocked!

It could be the LCD of your screen or a software has been corrupted. Have it checked by a technician. So that you would know if it needs reprogramming or LCD replacement. Have a nice day ahead! ^_^

Problem with the Nokia 6303i Cell Phone

• My nokia 6303 Hang while it start only nokia...

Have you tested it with an external monitor?

I would say you either have a damaged inverter board or screen baclight lamp. Usually the inverter board fails in one of the following ways:

1. When you turn on the laptop, the screen lights up for a short period of time and then goes dark. You still can see an image but it is very dark, almost invisible and definitely not usable. When you restart the laptop, the screen lights up and then goes dark again. The laptop works fine with an external monitor.
2. Your laptop turns on but the screen remains dark all the time. You still can see a very dim image outline. The laptop works fine with an external monitor.
3. The laptop screen works fine for hours or even days, but sometimes it goes very dark as it mentioned above. When you restart the laptop, the screen works fine again.

Inverter failure symptoms are very similar to backlight lamp failure symptoms and in most cases you cannot tell which one is causing the problem until you replace either the inverter board or the backlight lamp. From my personal experience, inverter boards fail more often than backlight lamps. If you have to guess, replace the inverter first.

You have to update your phone's firmware or re-install your phones software from an authorized Nokia Care Center.

Try a different screensaver.

Also look in the display properties by simply right clicking the desktop and clicking properties.

Then locate power management.

the initial seems to be a bad screensaver judging by the 20 minutes, but the 4-5 hours seems to be a sleep mode that bypasses the screensaver issue.

You have it on the battery saving mode. Go to Settings > Phone Settings > Power Save > turn it OFF.
