Hello! Going to buy my 1st smartphone, need advice.

[NightLunya]

Hello!

I'm, NightLunya , 21 years old
I am a computer technician and webmaster, administrator and manager of a nonprofit organization on a series of Japanese video games ( to avoid pubs, I will not put a link to my question here).
I also practices cosplay
I'm from Hainaut , Belgium. I speak French

I stumbled upon some video review smartphones and I fell on a YouTube channel named "JTGeek" who provide smartphone review in french , which then redirected me to a french forum. But, the forum looks so dead, so I decided to look at a large forum who speaks about China phones, and I'm now here
Now, I'm looking at a smartphone who worth value for my money, good but cheap , since my old cell phone or HS .

So I was tempted to buy a smartphone that I think good, but I think this forum will provide valuable assistance as exploring all brands available and attractive price, it gave me a little doubt about my choice ... And I guess with a lot of people who have more experience , you could help me. Be careful, I'm quite "demanding" ^^"

So...
I am much informed me on existing Smartphone when I came across some interesting products. But the more you look, the more we discover things, and therefore I'm really lost on the choice of the phone in question .

I have some criteria I search on the phone in question , as well as a few questions. I am a computer technician so I know the technical terms and use them, but since I am a novice in the great smartphone , I wonder about some utilities certain functions ...

Anyway , that's kind of what I'm looking for ...

What I seek of preference:

- Reliability : Something reliable, and pretty solid , no doubt marks;
- Longevity: Potential for a good life ( I count not change Smartphone every year) , I target to 5 years if possible;
- Screen: A beautiful screen , it is legible and fluid at the same time . Also usable in all conditions (gloves included). HD would be fine ^ ^ " A solid screen too, which does not break on the first drop of 10 cm . ... ;
- Multi- function : This phone will essentially be use for call, emails, calendar, show pictures / video presentation, Internet, and remote control of devices and computers;
- Powerful: But useful, in case of having something fluid and efficient , I am interested in the Quad -Core and 2GB RAM. I was told that Mediatek CPU were quite poor , so if there is way to avoid (even if it is the majority mark ... )
- Storage: For storage, if it has a MicroSD slot, it's OK ;
- SIM : Not required , but if it has a dual -SIM is better ... but it is a detail ;
- Size of the phone: I'm not looking a " phablet " wholesale upper screen has 5 " I'm not interested I want a powerful and multifunctional phone, but I do not need big brick in my pocket ^ ^ . "
- Connectivity: Wifi, 3G+, Bluetooth ;
- Language: Possibility to have it in French, but English is fine too;
- ROM: OS customizable , possibility to update . I guess there is only Android for this. Maybe ROM update too?;
- Autonomy : The largest possible. And if there is way to disable functions to extend the life of the phone , I'm interested ;
- Gadgets : Bwah , maybe Gorilla Glass?, and something that I could put the phone in case , I not looking for others gadgets.
- Other : If possible to IP57 standards. Not that I work in the dust or water , but at least the risk of failure is limited;

What I 'm not looking (basically, these criteria really does not matter to me ) :

- Storage: ROM I care very little. I was used to a limited 1GB MicroSD and 32 MB ROM phones. As the MicroSD can expand the storage, I'm fine ; BUT! In this way, apps should install on MicroSD. If not, a little ROM is anyway good.
- Gadgets Image: Camera: I have a Sony DSLR and compact . So the camera phone really does not matter. For videos ... I have a Full HD 60 fps Canon camera ... well... it may take photos and videos, but I'm not looking for high-quality, as I already have the items to do it ^^"
- Gadgets Sound: this is a smartphone , so the speaker ... should not expect superb quality . Honestly DTS , Dolby... I'm not interested . As long as I can put a headphone on and adjust the graphic equalizer to correct some missing tons , it's good ;
- Screen: A Full HD on a Smartphone? As the dpi is correct, a 1280x720 HD is ample . No need of 1920x1080 on such a small screen ;
- Connectivity: 4G ... honestly, I could compare the 3G + and 4G in many people and I do not see the big difference. So I did not necessarily need 4G. I think the 3G+ gives a rate sufficiently interesting.
- Appearance: Comments on phones that resemble others and being told that it is a fake, honestly I do not care. I like the design of the HTC, but I do not really bring the matter over .

My questions:

- I saw recently some Octo -Core Smartphone on the market. But actually .... the usefulness of Octo -Core compared to a quad-core on a Smartphone? Already on the PC, Octo -core has a pretty useless utility at this time.
- The frequency of CPU Smartphone Is very impactful ? I mean , is there a big difference between a 1.4 Ghz CPU and 1.7 GHz , 2 GHz see ?
- Since I intend to use this phone in the long term , is it wiser to take the most impressive components ( thus favoring a Octo -Core for the future, and more RAM ) or this detail is negligible ? Especially that at present , we always sell Single -Core and Dual -Core with a small RAM, so I guess these settings are far from obsolete .
- Battery extender : how it works ? What's it like ? Useful ?

_____________________________________________

All for a relatively small budget.
I examined the possibilities and I adapted my budget accordingly.

I would like to spend as little as possible , but I know that this kind of phone will not find at 50 € ( otherwise it would be a dream ) .
My maximum budget caps 250 € . No more. However, the cheaper the better .

I am very particular about what I want, but don't worry, I myself have researched and reviewed the best would fit my needs .
However, I think with your recommendations and experience, you may be able to find even better than me.
I heard a lot of branded goods as Xiaomi , Lenovo and Huawei, who deserve their place alongside HTC, Samsung ( Apple not talk to me , not at the ankle of the other technically ). In the opposite I heard many peoples having problem with brands like Zopo, so I'll avoid this.

My first choice was focused on a Huawei Honor 3 "outdoor", which is one of the phones that fits most in my selection criteria.
But I 'm interested in any advice, that's why I ask here .

Thank you for reading me that REALLY LONG subject ^^", see you soon !
