LG Nexus 5X, cost you about RM 1500, and you do get updates straight from Google first!

Should be good for multitasking and has a good value for money. For the camera, it shouldn't be that bad and for the battery, it's close to average, but remedied with it's quick charging.

Asus Zenfone Zoom would be a good idea albeit more expensive.

Leagoo Alfa 2, Leagoo Elite 4, Xiaomi Redmi 2 Enhanced and Asus Zenfone Go ZB452KG should be reasonably good.

Shouldn't be too bad. I would prefer going with the A7000 Plus, as it do offer a good screen resolution (1080p) and big screen at 5.5 inches, which is more to a necessity for old people. Also, A7000 Plus is the same with K3 Note.

Xiaomi Redmi 2 Enhanced would be he best choice, albeit still on KitKat. Lenovo A2010 should be also good, since it's on Lollipop and has a 64-bit CPU.

Alcatel Flash 2 (RM 540 at Lazada). It's 5 inches screen should be okay.
Asus Zenfone Go (5" variant) (RM 459 at Lazada)

For the first phone, I would recommend Alcatel Flash 2 and Xiaomi Redmi Note 3 (It's imported though, so don't confuse it with the local one.) As for the other one, the closest one would be the Lenovo A2010. Also recommended would be Leagoo Alfa 6 and Asus Zenfone GO (4.5" variant), if you don't mind not having LTE.

I would go with Xiaomi Redmi 2 Enhanced because it does offer some good updates. Alcatel Flash 2 is decent. Lenovo A6000+ would be last on my list.

Xiaomi Redmi 2 Enhanced should give you a good impression.

Samsung Galaxy S7 is the best out of the three. Choose Huawei Nexus 6P if you want a complete vanilla Android. Huawei Mate 8 is the last on my list.

If you would like a very good selfie camera, crisp display and, audio quality, go for the Zenfone Selfie. Samsung Galaxy J7 is good for its front camera and battery life. Xiaomi Redmi Note 3 is great for performance, display and software updates. If I can choose which was better, I would go with the Xiaomi Redmi Note 3.

That depends. The bigger space, better multitasking capabilities, audio and camera makes the Zenfone 2 a favorable choice. Whereas the better battery life, better performance and some good software updates would make the Xiaomi Redmi Note 3 a good one. Personally the Redmi Note 3 is better because the Zenfone 2 utilizes Intel Atom chipset, which wasn't a good idea if you ask me.

The best phone you can get based on your requirements would be the Asus Zenfone 2. Other phones that fit into the requirement is the Samsung Galaxy J7.

LG Nexus 5X is good if you want software support from Google, which also mean you can get the latest OS first. The Redmi Note 3 is quite a good all-rounder.

Well.... if you live in Klang, maybe there's on nice deal of the Zenfone 2 (4 GB RAM) at Tesco Bukit Tinggi at RM 850。 But of course, things aside, the Zenfone Selfie's camera is decent. But when we say performance, it's clearly just decent.

And as for the Sony M4 Aqua.... it's decent as well, but then, you should probably just steer clear of it due to the very small space even on the 16 GB variant.

Oppo F1 would be an ideal phone for you if you're going for camera, but the only problem with it was the battery itself. Huawei P9 lite is also another ideal choice, although you might suffer some problems with the camera if you take it on low-light. (Note that my opinion is based on some reviews on the internet.)

Lenovo Vibe P1m is the cheapest possible phone with execptional battery life and with 4G.

Lenovo K3 Note is pretty much like Lenovo A7000 Plus, which I might have to say that it's a good device, save for the camera, which is not very good at a price if you buy the A7000 Plus. However, if you say the K3 Note is being sold at RM 400, that's definitely a steal for it's price.

Would go with the Honor 7 over OnePlus Two. Huawei P9 lite is a somewhat better option there. You can also have the Lenovo Vibe Shot and Oppo F1, which has superior quality camera at a price of battery life.

The LG Nexus 5X is quite decent for the price. The Asus Zenfone 2 ZE551ML is not that bad either.
