i am using this phone at one weak. all futures were good perfomance.but i had feel one problem,that is few time useing phone,phone was heat.so this mobile was heating problem included.
I am waiting for an upgrade from 4.4.2 to 5.*.* version of OS and believe that the battery will keep better. But now I am happy having on my hands this phone and I can say that it has all what we need it one - the perfect performance, the big memory, the hudge capacity and does very nice looking photos and videos.
