I bought Samsung galaxy core 2 on January 2015. For about six months i.e.till August it worked preety well. There was no heating effect or sluggish behaviour of phone. But after some days the phone showed some resistance in touch. But I didn’t paid much attention to it. But after that it started to show sluggish behavior. I thought there might be some problem with the touchwiz launcher.
So I downloaded a different launcher from play store.It worked quite well for some time. But after that there was a constant heating effect.
I downloadeda game doodle army: mini kilitia but as soon as I opened the game the phone got hanged. So I removed the battery to get it in normal position.
My overall experience is really bad.
-THANKYOU
