"As most people, on receiving the HTC One S I was ecstatic. Such a slick and beautiful phone and the screen is fantastic! Unfortunately it just went down from here. Within a few days we noticed that the reception was very poor even compared to swapping the same sim out to another phone. It is so poor that you can hear the difference in the bad line when making or receiving a call and this only when there is enough reception to make at least one signal bar... It should be said that by reading some blogs with other users having the same problem we found that by switching the 3G off, the reception significantly improves�
The phone was eventually returned and a new one send out. Same problems. :�(
I decided to leave it like this with my work-around (turning off the 3G when not required) for a few months to see if an update comes out and the situation improves. Then a new problem emerged.
Started noticing the screen jumping (on it�s own) to the home (multiple screen a.k.a helicopter view) and back as if the home button is being pressed. This got worse and worse and is now at the point where we cannot use the phone as it almost constantly jumps around.
Off course I have been in contact with HTC about this and the problem is still outstanding, they have suggested; we reboot the phone, we clear the cache, reset to factory, and asked a multitude of question, but to no avail. Problem still persist with no fix in sight.
