Far too many defects

Have the phone now 1.5 years. Directly after two weeks it was already the first time in the repair, because it crashed constantly. That it does continue, especially after the load, it depends on yourself and not even the alarm function, which as you can imagine, can lead to extremely unpleasant situations when you have to rely on the alarm clock. Despite that I use the phone for texting mainly telephone rarely longer and I also do not stop much on the Internet, the battery is in the evening at the latest at the end. The supplied SD card does not recognize time and time and last but not least is now also the loading gate in mobile broken. Laden is no longer and therefore no backup from the PC ....... since one can safely yell. If you're thinking "ok, has a Monday Xperia caught" error, a friend has the Xperia smartphone as a normal (not the slider) of the latest generation and has the exact same problems. It was definitely for me the last Sony Ericsson
