Bug in GSM module while 1 sim + TF card Edited by Kurmanb at 2018-03-24 15:41
Hi guys! I have m5c, updated by air to 6.0.2.3.g When installed and used 2 sim cards there is no problem. But when I use 1 sim card + 1 tf memory card, the gsm connection unexpectedly dissapears sometimes. No connection. After a few minutes connection is stabilised. And sometime after, it repeats. Connection is beying lost, and regain in a few minutes. What is that sort of a bug, and how to avoid it? | |

I think the problem was caused by sim card not supporting 4g, or weak 4g covering area. Anyway, problem was not in phone, but on operator side. So, if anyone has similar problem, there are 2 solutions: 1) change your sim card with the newest one, which supports 4G, or 2) switch band mode of sim card to 3G. | |

A bug or maybe your memory card is bad or damaged. On my group there is someone that suggest to amount your SDcard and try to just using Internal Momory. Thank you.
