How can I see display better in sunlight?

Viewing screens that make use of "back lights" (LEDs, fluorescent, etc) to see / read the display in direct sunlight is often very difficult. Increasing the back lighting level is one method - but even when at 100% brightness, it is hard to overcome the sun. Shielding the screen from sunlight with your hand, body, etc., is often the only way that works effectively.

My nokia 6300 is all the lights i.e. display and keypads lights the are working the display has become black and white can u give me some instructions

Hello your problem is not relating to Lights,but possible problem comes from the failure of LCD/LCD socket/ Display IC (filter).So, to solve this you can at least open the case and clean the components/board near the display socket Or Re-insert the LCD.If this trick doesn't helps contact nearest mobile repairing shop.Good luck

Everytime I make a call it displays forwarding activated but I haven't forwarded any of my calls?

select settings on your phone icons, go to call options, and then check if you have call forwarding options and then disable or deactivate call forwarding option. If your phone doesn't display any option for call forwarding you need to consult your telco and ask if they have access in deactivating the call forwarding feature.:p

How can i format my phone(nokia 7210 supernova) i just forgot my password and i ve tried formatting using *#7370# and by switching it off... Nd pressing *3and call key... Then truning my phne on while...

The default lock code for Nokia is 12345 or 00000 or 0000.

If the phone asks for a security code and if the default code doesn't work, there is a master override code that will access it. Use this website-
You type in your IMEI, and it generates a master code to override the security code. Watch a video on this at

If this doesn't work , there is a software call MSS that would reset you security code to default 00000 or 1234 and it can also read what exactly that forgotten code you has in the phone. Search for the this and other similar software on

Since you don't know the lock code, you will not be able to reset the mobile.

Or else, if your phone is under warranty ,just bring back to the dealer where you purchased it or find the local dealer and give them the papers which identify that you are the owner of the phone. They will be able to unlock it. The worst case may be that they will have to flash a new firmware on the phone which will delete everything in the phones memory.

How to delete the crack file ?

You cant delete some crack files,because it is programmed to permanently reside in your phone.If you want to delete it then you have to format the phone or memory card accordingly.

Some time the file will be read only so right click and click on read only option again.and try to delete it.
To format phone-If you have the crack in phone memory then try this
code is *#7370#
Then select yes
default code is 12345

If you have saved the crack in memory card-
Put it in micro SD card and format it from computer...or

Options->Memory Card Options select "Format".

If still this doesn' work download and install DR.Jukka software and delete it.

Please do rate the solution if the issue is resolved or post a comment for further assistance.

The screen light on my phone doesnt work

More than likely, you've turned the back light off all together. Go into the menu, and display settings and find the backlight options.

If it's set to 'on' and to stay on for at least 3 seconds, yet nothing works: turn your phone off and then back on again. If still nothing, take the battery out, put it back in and start it up again.

If there's still no backlight, contact your supplier or the store you bought it from.

Lights on the numbers are not lighting up

Hi,Most phones will have that option in the display settings. You can mess with the lighting and timers on the main lcd, the front lcd (or led), and the keypad.If that doesn't work, there's most likely something wrong with the phone. Take it in to a corporate store to get it replaced with a working model.
