Thanks for the quick reply. Yes, I would appreciate if you could send me some pictures or upload them here. What are the springs actually good for? Do they provide some sort of grounding? Or is it a mechanical issue of pressing the ICs down? I apologize for my ignorance. Now, my SIM card connection is lost while I type on the HW keyboard, i.e. applying some force on the HW underneath the keyboard. When I stop typing, the SIM comes back after a few seconds, sometimes asking for the PIN again. Has anyone experienced this too?
