Dear friends, kindly let us know if A9 pro is still worth buying as it was released in 2016??? Planning to buy either this or Lenovo P2 as both have better battery backup. Please give us your suggestions.
Battery drain and heating of the device are two major problems after update.
Samsung has made some changes. This time around Adaptive fast charging is Not se as Qualcomm quick charge. With Samsung's own provided charger the quick charge is functional and displayed. But Qualcomm QV2 or 3 chargers don't work as fast chargers. In fact cjarg8ng current never crosses 1.5amp with any charger except Samsung's own adaptive fast charger. Too much push for properiety accessories.
It turned out to be the other way for me. With all my apps intact, the performance was good and no complaints. Thought of tweaking it further and did a reset. Now it went worse. Battery drain problems, over heating etc. Surprisingly Bluetooth is consuming 70% of the battery as shows by battery usage statistics.

asdf, 14 Sep 2017or just android 7.1.1I think Android 7.1.x is hardly a major upgrade, so I doubt it. But even if it's just 7.1.1 it will still be worth it.
Just got it, love the build, feel and look. Using it in the US with a Straight Talk Wireless card using AT&T. Have sim in slot 1. It shows "emergency calls only" if I put it in slot 2. Can someone tell me, is slot 2 the one that has bands 17 and 4? I'd much rather use that slot. Also, I use go sms pro for texting, is there any way to tell the phone not recognize the empty sim slot? Texting is acting weird because one slot is empty.
AnonD-684709, 16 Sep 2017I got mine three days ago (Chinese version), and it's just full of awesomeness :D No update... moreWhat country are you using it in? I just got it and working out some kinks in the US.
Everyone should do factory reset after the android 7 update then only your device will work properly . I did that and now it's flawless. Every thing is perfect now ...
@Nidhun - C9 Pro has 64GB & A9 Pro - 32 GB - Internal Memory unless you do lots of gaming or download too many apps , also C9 Pro is narrow than A9 Pro (Screen is less wider ) , Camera 16Mp Selfie in C9 Pro , 8Mp for A9 Pro , 16Mp back camera of A9 Pro has OIS , C9 Pro does not have OIS hence rear camera of A9 Pro is better , it makes a lot of differrence in photography.
