I took my Samsung A7 to repair as it needed a battery change. 1h after I changed the battery, the screen stopped working. It won't even let me unlock my phone. I tried restarting it numerous times with volume down + off button but it still won't work. I connected it to the PC and I can't reset it like this either. I don't know what to do and I don't trust those who changed my battery anymore, as they returned me my phone in an even worse state than before. What should I do?  

my Samsung a7 has been too slow even after wiping and wiping I don't know f there is any solution for this, if I restart it will work a little bit fine for a while but with time it will start slow again. tired and new help.
