[One (M7) General] c0rp1:
Hi guys,

as most of you here, I`m planing on buying THE ONE as soon as it gets to the stores in our country.

Because of that I started checking and reading the general ONE forum almost 15 times a day :o. One of the most important things for me, when I buy a phone and give like 600+ euro, is for the phone to be as perfect as possible at least the first couple of months.

That`s why I decided to make this thread as a guide that explains the main things you should watch for when buying the phone from your store !

1. Take a look at all sides of the phone and see if there are any GAPS or OVERHANGS, cause its a "unibody" design after all. Here are some pictures and link to original thread, where this problem is discussed:

2. See also if there aren't any gaps near the volume rocker, and if it doesn't stick while you press it (incl. the power button). I remember that one member here had a similar problem, but cannot find the OP.

3. After you power on the phone try to connect to internet (all major stores have free wifi) and download a Dead Pixel Test app from the store. Then check for any dead pixels on that gorgeous screen !

4. I bought a nexus 7 tablet some months ago and got a replacement, because of a bad headphone jack design. What that leads to is a cracking sound from headphones, when you just plug them and navigate through menus or slide through main screens, but don't listen to music or watching video. Many devices suffer from a problem like that, so I test that always in the store, either with the pair of headphones in the box, or with my own ones. In many cases that means poor shielding and can affect more parts in the phone itself.

5. Camera firmware (latest batch) : According to a camera test published here - http://www.hardwarezone.com.sg/review-htc-ones-camera-tested , pre-production units had some kind of a hardware issue and that's why many photos taken with the device seemed blurry on the edges.

So it's really good to know, how can we check if the unit we are buying is from the latest batch or not ... will update this when I have more info.

6. Phone display: this is where I`m a bit confused really. Here is the thread, where I read that the ONE can have different display characteristics in terms or color temperature, contrast and brightness.

Would be very happy if someone can explain that in details and suggest if this is something we must watch for, before buying our unit.

That covers the main things that I`m aware of till the moment. If you have any more suggestions, I would be happy to update the OP.

Also some more clarifications about 5. and 6. would be great :cyclops:

And one really important question which I would like to ask and don`t want to make another thread for : how does the heat affect the casing and is it a problem if the device gets too hot (cause I love to use it for gaming sometimes). In other words: Could a GAP or OVERHANG occur after some usage, because of the phone reaching high temperature?

Here you can see a thread, where guy speaks about a 44,4°C device temperature : http://xdaforums.com/showthread.php?t=2207645

UPDATE :

5. According to https://plus.google.com/+PhilNickinson/posts/BkaNVpcNySN it seems like its a software update after all, and not a hardware one ...

And here is a good guide on how to check if your phone is from a later batch or not : http://xdaforums.com/showthread.php?t=2209277
