1. If problem happends within 3 days of warranty , u can claim from him ( since he did not say wat covers for the warranty )

2. Another alternative if he could not come out with the amount of repair , u both can negotiate either 50-50 payment to be done (u happy i happy status)

3. He shouldn't say its 1% minor problem as this would mislead the buyer to buy it confidently. This consider lying.

Actually this case is very simple , just to see whether the seller want to solve for u or not~ if he wants to continue his business and taking care of his reputation, he should solve this matter with the buyer asap~

If im the seller , i would ask for your receipt of repair from nokia centre and i would have a " win win situation " then this case is rest~

seller : i think the best is that u take back the hp and refund ( for both good sake )

for alternative solution :-

dont wan to coz more trouble here~ if u keep on defending for urself it wont help u to solve this problem. Customer always right. If your keypad/board doesnt have problem , your customer wont grumble here n there.

You did stated 3 DAYS WARRANTY for your client and if the problem happends within 3 DAYS of your personal WARRANTY then u better quickly solve this for your client. Since your client so good that he willing to open his wallet and pay ( 50-50 ) on ur behalf ( to be honest the buyer doesnt require to pay 1 cent during your 3 DAYS personal warranty )

Please be responsible and sporting thanks~ just my 2 cents~
