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.
Now i have this firmware in my smrtphone for few days and it worked really perfect. This is simply the best firmware, which was available for Sony XPERIA XA yet. Also battery life is very good here, so i dont see any disadvantages. I am not sure, if there will be new updates for this device, but if 33.3.A.1.97 was latest update for this phone, than i dont have problem with it and i understand that Sony Mobile developers now hard work on Android 8.0.0 Oreo update for another XPERIA smartphones.
