Hi,

After hours of trying, I wasn't able to find a SGF viewer for my Samsung BT3100.
I tried the following software:
- jimmygo (it doesn't have support for loading SGF files)
- mgo (it loads SGF files, but displays only the first 5-6 arranged stones with AW[] and AB[] tag)
- rgo (it shows the message "java error")

If anybody had success in solving go problems on mobile phone, please advice. Any help is appreciated!

There are a number of apps that come with problems of their own. Wbaduk for example comes with a set of 2500 problems, and gobandroid comes with a problem set from gogameguru that is updated weekly. A few others that are specifically for tsumego are: gogrinder and tsumego pro. I think gogrinder lets you import problems. I'm sure there are others, but that should get you started.

Thank you for your answer, but I need software that can run on my mobile phone. Gogrinder and Wbaduk require Windows.
Gobandroid requires Android.
My Samsung BT3100 runs a proprietary operating system, so none of the above will run.

I wonder what kind of phone this is. I googled "Samsung BT3100" and found nothing that looks like a cell phone.

I think once upon a time I used HandyGo, and it was very fine.

Sorry, my phone is Samsung GT-S3100, not Samsung BT3100, my mistake.

I tried HandyGo, but it can be used only to solve the 30 problems it comes with.
