I'm getting " invalid card" error randomly ,in my HTC one 32gb unlocked version,I bought it from HTC online shopin May last year ,was working fine except the issue of purple tint in camera for which I sent it to repair to Houston ,Texas a month back ,they did great job ,my camera working great ,no damage to device .
But now I'm having issue of invalid card ,which occurs randomly,rt now I'm s-off , running viperone Rom. I had this problem with stock 4.4 Rom & custom rom as well,I tried to change firmware & also roms but with no effect .
Many a times phone works flawlessly,but sometimes starts showing this error causing call drop .very annoying.
Some says it is because of defective SIM tray,it that case why I had no issue earlier?why it occurs randomly ? Why not always ? Enquired with service provider they say no issue with them
Any one having this problem ? Any solutions ?
