Having used the phone for a weekend now, here are my grievances listed in order of severity:
1. Function keys. Who thought this was a good idea?!?! If they had just put the ?/ key where the right function key is, they could have completely eliminated them and used a standard QWERTY layout. I am investigating options to remap the keys, but the keycaps are wrong and from what I understand not replaceable even if fxtec came out with a sane qwerty layout.
2. Lack of verizon support. The pro1 was clearly advertised as being compatible with verizon, yet is not actually supported in verizon. I have managed to get it halfway working, but coverage is terrible and sms delivery is intermittent. "Messages" shows an error "no SMS connection" all of the time, and sometimes messages come through but now always. I am currently investigating options to migrating to a different carrier since the whole reason I wanted a keyboard phone was for messaging and I need reliable SMS capability.
3. Keyboard spacing - the keyboard is too long to efficiently type on. I don't exactly have small hands, but I am often overextending my thumb to get to the keys in the middle of the keyboard. I also have issues with missing keystrokes, and for whatever reason the spellchecker only catches about half of them. Hopefully I will get used to it, but missing keystrokes is a really annoying failure mode for a keyboard and kills typing efficiency. If I ignore missing keys I am up into the 40-50wpm range for unformulated text, but with even simple formatted text I am down in the 10-20wpm range due to the terrible shift layout and missing keys that seem related to my relocating my fingers going from shift/function back to the home row. It also doesn't help that there are no home row bumps on the f/j keys so when you loose your footing there is no option but to look down at your fingers.
4. Phone is gigantic. I mentioned this before, which makes not only awkward to type on (need to bend wrists to get to fgh keys) but also a beast to carry around. It is the same thickness but much larger/heaver than my droid 4 or even the priv. I really hope the pro2 comes in closer to the size of the droid 4 because if they make it any larger you may as well just get an ultraportable laptop with real keys. I appreciate that it has a larger battery, but if the screen were smaller it wouldn't be necessary to have such a large battery.
5. Curved screen. The touch region of the curved screen comes into the number key region, and I am constantly creating false touches while typing. I hope that they are going to be able to fix this in software, honestly at this point I would rather have the phone configured to have the outer few millimeters of the screen blanked off and touch disabled so they always show black and the curved edge are effectively removed from the screen. Also, the color temperature varies wildly with brightness changes, so when auto-brightness control is enabled websites color pallets drift like crazy as the room lighting changes. It is especially noticeable on off-white websites like news.ycombinator.com
6. Notification LED is way to bright. I can use it as a flashlight at night, and see it through the fabric of my pockets... I am working on a way to add some black ink over the led to tone it down to a more reasonable level.
7. Middling processor. It has a snapdragon 835 which would have been a good processor back when the kickstarter was happening, but current gen phones in this price class have literally double the processing performance. It is still an order of magnitude more responsive than the droid 4, but at the rate we are getting keyboard phones these days I would have liked to see fxtec future proof this a bit better so that it stays usable until the pro2 comes out in the mid 2030's. (sarcasm)
8. Serial number label on the back. It looks like a serious afterthought, and the ink on my label is already starting to get worn off even though I have only had the phone for a weekend. I already peeled it off--luckily the adhesive comes off nicely. Why didn't they put it on the inside of the hinge?
9. Keyboard backlight is really uneven. It is functional, but the phone looks like the keys have been worn down or something and it distracts from the overall image. In particular ' and " are basically completely dark on my device.
10. Sim tray is really scratchy. I have used other phones with the same style sim tray and they weren't nearly this bad. Honestly it feels like I am inserting the tray in upside down or something--maybe there is some kind of misalignment between the outer case and the contacts in the phone on my device? I have a single active sim which I swap between several devices as appropriate and I am worried I am going to wear out of straight up smash the sim tray after the first few swaps.
Software issues: Maybe these will be fixed with time?
11. Lack of 3rd party OS. The marketing material prominently shows sailfish and lineage compatibility, but neither of these are actually usable. Hopefully the community will be able to get them working, but it is looking more and more likely that official sailfish support (and with it, the ability to emulate android) is never coming because that would require effort on fxtec's part. I specifically bought this phone to run sailfish and am highly disappointed that nearly 6 months after the phones release they still do not have a working sailfish port. It is amazing how far the community has come, but given the small userbase of these devices the community is also small and can only get so much done without official support.
12. Camera is terrible. Using the stock camera I cannot actually take pictures (after pressing shutter soft or hard button the screen blinks, but does not save a file) and the front camera is not even detected (pressing the flip button causes the screen to momentarily go blank, but then the camera resets to the rear camera). Using gcam the cameras both work, but it takes over 30 seconds to get an image (after starting gcam, the image is frozen for about 30 seconds before the camera starts to work), and the hard shutter button doesn't work. At least the front camera works so I know it is not a hardware problem. Yes I am running the most recent firmware.
13. Lack of a multiboot bootloader. As far as I can tell there is no way to have multiple roms loaded on the phone, which is a bummer. On my droid 4 I used safestrap which allowed me to swap between the stock android, a modern version of cyanogen, and an older cut down version of cyanogen without gapps. I really miss this feature, and dearly hope that the ability to run multiple roms will be added to the bootloader soon. It would really take the edge off of the unfinished Sailfish build if I could also have a working version of android with me in case I run into trouble.
14. Keyboard backlight doesn't work correctly. If the screen locks, you have to close the phone and re-open it and unlock it to get the keyboard backlight back on. Especially annoying since there are no homerow bumps so blind typing is nearly impossible. I also haven't found a way to get the phone to unlock on opening the keyboard, which would be a nice feature.
I can write another post on the positive aspects but it sounds like you guys already know them all. In the mean time my thumbs are tired
