After 4 months of using the micro usb female SMT Socket Connector broke by accident. I had bought a bottom angle micro usb cable http://www.ebay.com/itm/310712144379?ru=http%3A%2F%2Fwww.ebay.com%2Fsch%2Fi.html%3F_sacat%3D0%26_from%3DR40%26_nkw%3D310712144379%26_rdc%3D1 to avoid putting pressure on the connector.However using this cable, the connector broke.
Maybe a more resistant case will be appropriate to avoid such kind of damage.
