-Sometimes i receive SMS 30-45 Minutes after they have been sent, that happens about 2 or 3 times a week
-Sometimes people call me (with 3 of 4 signal strength bars) and they cant get trough, they reach my mailbox
-Sometimes people call me and after 3-4 Minutes the call stops and they have to call me again.
Galaxy Note N7000 with CM11.0 - But im quiet sure i had this problem with other ROMs too (But all CM, no Stock Samsung ROMs)
I changed the USB Connector on my Note because it was broken - The USB Board has the Antenna Plug but i fixed it the right way, i did everything as intended.
-Sometimes my Wifi is not able to turn on but after a reboot i can turn it back on all the time (Might be CM Related? No Samsung ROM)
I hope you can help me, i rly want to have a working phone again.
Thanks for your help, best regards from Germany
