K1000716:Brendan:mckenndk: I am having all sorts of issues with my SGSII.
The car mode for the voice recognition keeps starting up randomly, Voice talk (usually accessed by pressing the home key twice) randomly comes up and it goes into MTP application mode (when you plug in the USB to do stuff with kies) at its own free will with no usb cable or wifi connection at all.
When I receive calls it starts in Speaker mode and after you switch it back it will randomly during the conversation go back into speaker mode witch is a pain.
I have factory reset the phone and removed the SD card but the problem still persists.
I have emailed Techbrands when I bought the phone from and am awaiting a resoponse from them on were to go from here.
Have you tried a new odin ROM flash?
If so, and you still get the issues, i'd say it's faulty. Warranty it before it's too late.
Could this also be a candidate for foreign objects in the usb port? It is pretty easy to get fluff and other tiny debris in there and it has been the cause of numerous unrelated issues before (as reported on XDA).
More than possible. Moisture, dust, etc in the usb or headphone sockets could cause all sorts of trouble. Puzzles me why Samsung didn't have sliders for those ports...
But somehow I think his problems go deeper than that. If it was a simple as what you suggest, I think every one of use would have had the same trouble at some point with our phones. But it seems rare.
