Does anyone have experience with the Samsung sch-i405? Someone brought it to me, and it's quite an interesting phone, the only 4g phone I've seen with a physical qwerty keyboard. It's pretty old, it runs Android 2.3, but it looks like it was pretty feature full for that time. But I was having issues picking it up with adb, I read online that pressing build number 7 times would enable developer options, but it didn't seem to do anything. I ended up finding an option to enable usb debugging somewhere else in the settings, but when I plugged it into my computer, although the phone said usb debugging connected, on the computer adb devices turned up nothing. Cycling usb modes didn't help. The only thing I can think of is that my version of adb doesn't recognise such old Android versions. Does anyone else have experience with this phone or a similar one?
