Samsung S2 phone won't turn on
My Samsung Galaxy S2 (which I bought in 2011) suddenly turned off last night and won't turn on. I changed the battery 6 months ago and it was working fine.
I tried the below and still nothing.
1. I tried to charge the phone, but the phone is getting hot as if it is charging but I couldn't see anything on the screen or able to turn it on.
2. Tried with my old battery, but still nothing.
3. Tried turning it on by holding power button + volume up/down buttons. Still nothing.
My phone did not fall down recently or contact with water.
Please let me know what I could do to revive it or if I could do anything to get the data from my phone.
