Numbers 4, 6, 0 and the left key on the joystick do not work. Do I need to replace the IC? It could be related to a disconnected pin or soldering problem. Please advise.
 
just you try new keyboard,,,,,if still same ,,you need change main flaxi,,,,,that also can make this problem,,,so try and post result
 
So I did nothing, and yesterday my phone went back to normal. Everything is working now. I guess there was some moisture, or water, and it's evaporated now.
 
Hello
When some keys dosnt work from down side and some from upside ,this isnt key ui prob.
It is circuit prob.
In this case may moisture confuse ui working.
