ok they are not refunding. Is there any garentee that they will fix it ?
im getting these problems in my cell
when a call come i am unable to accept it because touch screen wont work i have to set it at home button
sometimes sound issue(earphone plug out sound wont come through headset speaker) but i get it fix by myself
major problem battery, it drain without using it happen once in week.( i charged it at night and in morning my phone was dead because of battery drain automatically)
but one thing i didn't face that black screen problem so far im using this set from January its almost 6 months
Don't worry you can get rid of these problems by flashing ZSLE6 ROM because i am using it and i have never faced these problems...
If you don't want to install it take it to Samsung Service Center they will re install the stock ROM and check it, if you still face these problems they will replace the motherboard..
