All phones are quite the same and there is no interest to choose the most powerful but you should only buy phones with clean Android, I mean only android and no shiiite software on top of that as HTC Sense, Huawei I don't know the name, Lenovo I don't know the name, etc...

The only pure Android phones I found are imobile and Samsung, most of the other brands modify the Android version and you have to wait that THEY (not google) decide that you can update to update when they want.

You need to get your information straight before you post. The ONLY pure Android phones are the Nexus phones. All the rest are modified by the providers including iMoblie and especially Samsung.

You are wrong but no need to argue, I get bored with people on this forum who always know everything better, but it's ok, I just wanted to help, I don't care actually.

Your obviously well informed...NOT.....If you don't care then don't post...

Lenovo is releasing the phone in China on April 30th and will sell it for just $290, an incredible value for the specs.

Lenovo make great laptops. I'm just getting an x240 which has a 20 hour battery life.
