[ONE General] ddggttff3:
Time for my little drop of input after owning and using my OnePlus One for 24 hours.

Initial Thoughts:

Now to start, let me say that before this device, I have never used a "phablet" device. I have always been, and always will be, a fan of <5" display phones. Before this I used a Nexus 5, and before that a GS3. Both phones fit perfect in my hand, and were easy to use one handed.​

Screen: 8/10

The Good:

When I first turned on the device all I could say was "Wow, this only cost $350?". The display on this thing is actually one of the better displays I have seen in a device. Now personally, I enjoy my over saturated Samsung AMOLED displays, but colors on the OnePlus One feel a bit more realistic even if a bit warm. I have really enjoyed the entire media experience on my device with PopcornTime and Netflix and even with the dislike for the size, I can live with it due to the very slim bezels.
​

The Bad:

In my opinion, its a bit... large (see initial thoughts). Compared to the M8, G2, S5 this thing is a tall beast but with that in mind, its not as wide as a note3, and fits a lot better in the hand then most other devices. Also I want to comment on the "yellow screen" issue. My device seems to lightly have this, but I have a good feeling its the glue settling. This issue happened to apple with their iphones when they came right off the assembly line and into the hands of consumers (Link) and ad my OnePlus was assembled on 6/5/14 (according to the box), this is the most logical explanation for the "issue".
​

Hardware: 8/10

The Good:

If you are here on XDA and you are reading this, you probably know the specs of the device so I will leave that out. For real world use, the device seems to perform great with any and all tasks I throw at it. Games are smooth and fast, and the speakers on this device are FANTASTIC! No, really. I am in love with these speakers. Coming from a N5, the difference is like night and day. The speakers are actually so impressive, this is the first device I can't leave my ringtone/notification volume on full as it actually hurts my ears. As for the mic and call quality the device seems to perform great, even though the device does not support VoLTE or HD Calling on T-Mobiles network at the time of this review.​

The Bad:

I don't know if this is a bad thing or not, but it seems to be for quite a bit of people. The hardware in this device is almost the exact same as the Oppo Find 7. What do I mean by this? They use the same Baseband Base, Bootloader Image, and even the same pcb design/layout. Hell, they didn't even change the strings in the bootloader, so if you run a cat /proc/cmdline you are greeted with some boot arguments and some "oppo" setprop variables. Now personally I don't care about this, but it has caused some drama on the Official OnePlus One Forums (Which seems to always be full of drama now a days)​

Battery: No Score

I really wish it was user replaceable, but that's not enough of a reason to hate it. For being a 3100+mAh battery, you would expect the extra 800mAh compared to the Nexus 5 would give it quite a boost in runtime, but with my usage I am not seeing any large difference in runtime between my Nexus 5 and the OnePlus One. The reason I will not give this category a score is because I have only had the device for 24 hours, and to rate the battery performance so far would be pointless.​

Reception: 7/10

So far the Reception on this device seems to be on par with my Nexus 5. Decent, but nothing amazing. I am glad to see that the OnePlus One has no issues taking advantage of T-Mobiles wideband LTE network, and I was successfully able to pull a speedtest of over 80Mb/s download! But with that in mind, I did have one hickup with the thing. When I was out and about I was having some issues with reception hand off between LTE and HSPA+. My device would drop from LTE to HSPA+, but never connect to data. I had to restart my device about 3 times until data came back. Now I don't know if it was because I was in a building, but this kind of left a sour taste in my mouth. I was showing 3 bars of HSPA+, but I had no data connection. Bleh.​

Design: 9/10

The Good:

The feel of this device is amazing. When you first hold the device, the texture of the back really stands out from other devices. I have the 64GB Black model, and it feels like a soft fabric almost, but rubbery at the same time. It's really hard to explain, but it feels really good in the hand. Talking about which, I love the button placement on this thing. It's nice not having to shimmy your hand around the device to control it with one hand.
​

The Bad:

Only flaw with the design I would say is the Plastic Chrome edging on the device. As you know, the back plate on the device is user replaceable but is a pain in the ass to get off. To get mine off, I was really careful and used some opening tools and pry tools. After going around the device, and lifting the clips the back popped right off. After looking around the device though, I noticed how the chrome plastic trim bent and mis-shaped in some locations. Now this in no means hinders the device to work or put the back panel on, but I am nit-picky with how my device looks and I want to keep it looking perfect for as long as possible, and the fact that just removing the back kind of deforms the trim makes me wonder if OnePlus ever took into consideration the amount of work required to remove the back plate.​

Software:7/10

The Good:

On the software side of things, this device really shines with the CM11S firmware. It's fast, fluid, and full of nice features. Personally I love the double tap to wake, and gesture support. So for example, when the device is off I can draw a V on the screen with my finger and this will turn on the device's flashlight. I wish they could offer custom gestures (so I could draw a X to put it in vibrate mode, or things like that) but I understand that the firmware is technically pre-production. Hopefully CM will get more things implemented before the public release of the device.​

The Bad:

I found it strange that out of box, my device came "setup" so the first thing I did with my device was do a data reset to properly go through the setup process. I have also found a few privacy settings that cause Force Closes of the setup app, so in time I hope those are ironed out. Overall the software just feels like a nightly and not a production software image. A user should not have to reset a device just out of box because someone in QnA forgot to do their job, and none of the settings in the settings menu should cause Force Closes. I love Cyanogenmod but if they want to compete with the big guys, they will need to step up their game a bit.​

Overall: 8.5/10

TL;DR: Screen is fine, Hardware is fast, Battery does its job, Reception could use some love, Design is AMAZING, Software is good even with some minor flaws, and the SPEAKERS ARE AMAZING! If you can form up $350 and get an invite, this is a no brainer purchase​
