This afternoon.. a triangle icon show up next to the signal or 3g bar area..I don't know what's icon mean for . Late, i figure some of my app can't start up, because most of apps installed in memory card. So, reboot the phone and a message up after reboot, it needs to format my memory card. I ignored it, and now.. it can't detect any of my memory card.
Is there an app (device administrator), in which i can set my sim card.
Every start of the device, it detect the sim card and if it is not the same, it will ask for a pin (or it will send an email with a number to my account)
If the pin is wrong, the app will reset the phone to factory reset.
Hello Everyone !
My S II can't detect of SIM card anymore. I took off the SIM from phone once and when I put it back in again. It doesn't work anymore. I've tested the SIM in other Phones, it works and vice versa. I'm from Asian region. I don't think I can send my SIM back to my carrier will I don't do anything wrong apart from that. :( Can you tell me what to do now ? need help ... pls...
My case involves a Sandisk 32gb class 6 MicroSD card. Initially my S3 says that I have a blank card, but later it can detect the card again. For a few days this keeps on happening, on and off. Until the S3 continuously says the card is blank for a whole day.
