It seems the circuit controlling reception has been damaged. The only thing you can do is subscribe to your carrier's service & repair or insurance plans and ask them to swap the phone for you.

I need to block a number from calling me (on my sanyo katana) is there a setting in my phone or do i have to call my provider?

Hi, on this make and model it is not possible to set up call barring the phone has not got the software to do this, some newer phones can offer this feature but most dont.
the only chance you have got of getting a number barred is by calling your service provider and tell them you keep getting nuisance calls from the number you want banned and tell them to block all calls from this person.

as your phone does not have the software for call barring then this is the only way of blocking a number, you need to call your service provider as they can block it for you, but you need to tell them its a nuisance caller and you want them barred from calling your number.

hope that is some help to you

Sanyo pm 8200 sprint service no signal

Not sure about the bars, but you can go to the settings in the main menue and try to go to roam only. It could be that you r carrier is having a problem with their tower. Your phone, normally, will try to stay on your carriers towers. If you force it to a roaming status, you might get a better signal, but on a roaming network.

Good luck!

I need a driver to connect my phone to my laptop, its a sanyo 7400 and it jst says cannot find drivers software

When you buy the phone, some manufactures charge for the drivers and a kit for using a computer with the phone. The drivers are not expensive if you have to buy them.

I would not trust downloading the drivers from any sites, unless I know 100% that they are safe.

This is what I would do to start:

Go to the Sanyo site and see if they offer driver downloads for your phone.

Call the dealer where you bought the phone and ask about the drivers, and software for your phone.

You can call Sanyo's tech support and ask them how to obtain a copy of the drivers.

I have a feeling that the drivers and software are not free from Sanyo. If I remember correctly, when I was phone shopping they were telling me that they are extra. This is one of the reasons why I bought a Motorola. It comes with everything I need.

Cell phone disassembly

The screw is hidden underneath the plastic so you'd have to break the plastic to take apart the flipper. Not sure how you would put it back together though.
