I was on a holiday in Thailand and bought a new 3DS XL (hacked version) with an additional purchase of a 16 GB SD. I updated both the CFW and OFW to the latest version everything seems to work fine until about 2 weeks in. I have been having this weird issue with the lower left part of the touchscreen. It is not responsive but sometimes it just clicked by itself and can get very annoying at times. I have tried cleaning it with all options including a toothbrush. Note: I have a third party touchscreen protector and a screen protector on the 3D screen as well. Is this an issue related with software (CFW) or is it a hardware issue?
Weird, then. Usually a touch screen being both unresponsive AND reacting to spurious random phantom clicks usually points to an uncalibrated screen. I would say that the issue persisting after a calibration points to bad hardware (dying touch sensor/screen), though I would defer to someone here more knowledgable about 3DS internals, given my limited experience with teh insides.
