If you want to buy a mobile phone, please introduce one. Android (Android2.3) system costs 500-2000, with direction keys in the middle and telephone keys on the left and right.

This kind of Android phone with dial button and hang-up button is close to elimination. Are you sure you want this?

Personally, I think there are still many choices within 2 K.

Xiaomi 1s, 800w camera, Qualcomm dual-core, asv screen, large-capacity battery. Everything is fine. In order to meet your requirements, the meter key can also be set to dial.

Then you can watch Xiaomi m2 later. Powerful performance and affordable price. Official price 1999 yuan.

If you look at Taobao, you can still find lg p990 (licensed 993), 1500 yuan. Dual-core t2cpu, 800w, nice photo. The ips screen works well. The size and standby are also reasonable.

In fact, the battery of the mobile phone will last for a day and a half. After all, lithium batteries are easy to charge. Computers, chargers and standby power supplies are all available, which will not consume the battery life excessively.
