"invalid card " error

Hello,
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 ?
Plz help

hmm i also think so.
but why it will work initially and than stops suddenly??im not able to understand
Or is it a software issue ? Many people complaining that kitkat update causing this type of errors !
When they took apart the phone and put it back together they may have broken or left loose something that eventually shifted or shorted out. Or it may just be a fluke that the sim slot went out. But i would try to blame it on them lol :-\

There may be an internal short that fries the sim card.

Do you solve this problem?
i started having issue with my camera after 12.5.9 update my default miui camera app would close after clicking one photo although it was working in other camera like snapchat or fj camera. But few days after 12.5.10 update both front and back camera completely stopped working.
I unlocked my bootloader to downgrade the rom or flash custom rom as this seemed like a software issue . But after a week when i downgraded to my surprise the issue was still there which implies that the camera hardware has failed . So i dropped the idea of installing custom rom and instead went to service center, now they are replacing the motherboard as its hardware issue . I am gonna get back my phone today from service center so will update you guys accordingly .
Blog Link - This is the blog link which discusses about same problem even xiaomi has accepted the issue.
Its weird that software update can cause hardware bug but what i think is that with the update kernel setting might have been changed which can cause over voltage to camera module or something. Its my wild guess i don't have much idea about it . I would love to know it from experts out here .
