Sony excellent but my model was planting

The overlay of Xperia is particularly good and ergonomic, it bears comparison with the flagship models of the 2 other majors that I also own and yet they flanks me much more expensive. Xpria do better. The micro SDHC card reader is present. It supports 32 GB. I have not tried the microSD 64 or 128GB, supported by the latest Samsung. But as the second major does not expect this player to sell at a high price of flash memory, I think the SP is very good in comparison. Warning! Android does not agree to install applications to external MicroSD card, as we do for 10 years on our GPS. Only microSIM are accepted.
On the model for Europe, English interface default SP, French is selected during first use or after a short initialization, and can be changed later in the parameter. Banal!

I liked everything in the SP immediately adopted. Too bad it turned out quickly defective, forcing me to reset my MS every 4 days. Its operating system was becoming unbearably slow before planting.

Under these conditions, no further physical control stops responding, the reset, which is not super zero since the irremovable battery can not be removed or changed. This is his second fault.
For those to whom it happens, there is no alternative but to wait one week without charging, so that it runs out, which resets the phone and other smartphones

The cause of the bug is probably ridiculous, like all. The smartphone becomes a luxurious decorative object useless ...
Everyone does not encounter this bug. Probably far from it (?) But I'm still not alone either to have undergone this software incompatibility. Series can be bad?.
No Sony ad. It's a pity
I sent the Xperia SP through the Amazon warranty.
Thank the No. 1 mass distribution passage for the quality of its services and its remarkable efficiency. This is an example copied due but not equaled in terms of services.
