SONY T2 ultra is the best device I,evr had. Im looking foward to see sony release a fone with 3GB RAM like ausus and samsung.
Camera is brilliant outdoors but struggles indoors specially in low light, it takes a lot of time to capture photos & most of the are blurred.
Here is video testing tuch sensitivity sony xperia t2 ultra with sony glove mode without wearing glove https://youtu.be/7_m_xWrgwfQ
Made the switch to Sony from Blu 6.0 lte because of lollipo.. No regrets at all. Use the xperia companion on yourself to update to 5.0. While the specs are mid tier, you get a lot for the price of the phone. The Sony UI works great with lollipop.
One major drawbacks is the front camera. 1 megapixel doesn't cut it by today's standards.
Overall a great phone
