New phone and immediately buggy, lag and hang

Где в москве могу найти гарантийный сервис? Телефон не стоит ни 1 рубля с такой работоспособностью! Никому не советую покупать! 

Where in Moscow can I find a warranty service? The phone does not cost 1 ruble with this capacity! I do not advise anyone to buy!

Hi @Ejikin, welcome to the community.

You will need to contact your Local support team for assistance with repair centres. However, based on the information you have provided I recommend you perform a software repair using Xperia Companion.
