Sony XPERIA XA is one of the most stylish XPERIA smartphones on the market. Phone go to market with Android 6.0 Marshmallow, but now there is much better Android 7.0 Nougat available for this phone. From the start there was problema with internal storage, which has really poor capacity. But with latest firmware 33.3.A.1.97 is phon faster and there is more space in internal storage. This update also contain new security patches from Google, so i really reccommended installation for you.
