I've recently flashed a few custom roms on my new Galaxy Nexus and experienced some button issues. On both AOKP and LiquidSmooth, I've had an issue where the Navigation Bar (buttons at the bottom of the screen) lag or freeze. Sometimes this is brief and hardly an issue, other times the buttons stay frozen for several minutes. The rest of the phone, and any apps continue to work fine (minus the ability to go back/home). This never happened at all while running the stock rom, but both of these custom roms experienced this issue. I've done some searching but I can't find anything similar to it. Has anyone else had this issue or have any suggestions on how to fix it (besides an obvious workaround like Button Savior, etc)? Edit: It by using the developer tools, it seems that the bottom portion of my touchscreen periodically fails. Going to have to request a replacement. *Edit2: Reflashed a nandroid of the stock rom and utilizing the developer tools shows everything is fine. I can draw lines all over the nav buttons whereas on the custom rom it cuts out so much that I can hardly draw *a* line over that area. Guess I'm back to my original question, has anyone had this happen before? Should I still consider getting this phone replaced? I have no idea why the touchscreen would function properly under one rom (stock) and not others.
