Not really sure what is wrong my phone but battery life is pretty poor although I am not exactly a heavy user. When my battery is charged to 100%, I only get "estimated battery life: 10 hours"
It's normal for a new samsung phone. The phone is estimating according 7 days usage. Give it few more days. It will become more than 10 hours.
well for malaysia, they will say No stock for 1 to 1 exchange
Exactly. They won't change for you even if they have stock. Seriously, since Samsung always have quality control issues, theu should learn from Huawei. Given that the price is not cheap, providing 1 to 1 exchange is the least they can do.
maybe they rushing to keep up orders, so didn't check deeply
Actually do you guys ever wonder? Because the first batch have so many issues, that's why samsung postponed the release date. But still, they need to attend the pre-order units as promised. So they sent out those first batch, and the pre-order users bear the luck.
