Hui new hi10 low volume

I bought this hi 10new. I almost have no volume. I have tried to reload drivers and didn’t help. The battery will last for about one hour, when I type I have to give it time to show a letter on the screen before it will show the next letter. I have to drag an extension cord around everywhere I take it because of the useless fucking battery. I need support from chui about the low volume. And the answer from them is that the speakers are so small one should not expect good sound. An average phone speaker in 10 times Lou der that this piece of shit. After the sale these mfukers dont give a shit about support. I’m sending this fucking thing back to Amazon for a refund. I will never buy anything with the fukin name chui on it again.
