I have been using a LEX11 on Verizon for several months now. As stated, smaller than a Sonim but still very sturdy. Many drops without issue so far. Plug and play with Verizon SIM, but be sure to enable 4G calling (off by default). A few issues you should know about that I have found:
-With Verizon (not AT&T / firstnet) visual voicemail is not supported. You need to do it old school way (hold the 1 key) and enter your PIN to get voicemails, unless you have the advanced voicemail feature on your line of service you won't even get a notification when you receive a voicemail. Advanded voicemail send a cryptic text, I assigned that source text phone number a unique ring tone so I know when I get VM
-dual SIM works between AT&T and Verizon, but if you switch to AT&T and take a firmware update you are SOL on Verizon (the AT&T firmware does not allow dual SIM or VZW functionality) so you have to go through a very lengthy manual process to downgrade firmware. Say good bye to all your apps and data. For this reason Motorola is not advertising this as a dual carrier phone.
-Motorola suggests future firmware to fix dual carrier and visual voicemail
-Due to noise cancelling mics used in the LEX11 any videos you take with the phone will have some seriously funky audio. For the most part the voices will be intelligible with any other background noise muffled or absent. There are definatley times where you want that background noise
-When using LEX11 as speaker phone the party on the other side will also comment about funky audio, it seems background radio noise makes the problem worse (while using phone in speaker mode while seated in a squad with background mobile radios active)
-Camera pictures seem to be darker than my old Iphone, I am not overly impressed with the LEX11 camera. I acknowledge this may be an Android issue and not the phone itself. HDR camera mode seems to help.
-Motorola is making a 2 wire earpiece kit for the LEX11, a small clip mic and an acoustic tube ear piece. I tried it while BT to the radio to avoid using a speaker mic. The PTT talk permit is very delayed when using the LEX , like 2 seconds from PTT to the tone so be aware of that also the LEX was dropping my talkout audio at times. Pairing to radio is cool, the TG/ZONE features, favorite TG tab, and search are great for fat codeplugs but this feature is NOT mission critical yet. Perhaps this is more reliable with the AT&T LEX11 firmware, I have not tried that side yet.
-LEX11 will not do calling on 3G Verizon, data does not seem to work on 3G either. But I think this is also the case for the newest competitor smart phones
-LEX11 is also running old Android firmware, on Verizon its at 7.1.1 - I have not had any issues getting Apps to work
-The two card SIM tray on the LEX11 is a little tricky to remove without damaging the tray door
-The standard carry holster for the LEX11 uses the Peter Jones Klickfast stud system common in UK policing. The belt dock is large. Do yourself a favor and pick up a Si500 camera holster with coat pocket clip, remove the clip, and connect it to the LEX holster. The bolt pattern on the back of the LEX holster is the same as Si500 and XE mics. The speaker mic clip will bolt on too but I found its not robust enough to hold to the belt.
-The LEX11 worked fine with the old SIM from my Iphone 5S. If you activate the LEX11 on Verizon, and turn on 4G calling in the phone, and still can't make calls contact customer support and verify option SFO 81158 (HD Calling) is active on your line of service.
-The high capp battery is lasting me up to 3 days between charges, but it does add some size to the device. The standard battery needed nightly charging
-My LEX11 randomly fails to charge. Light goes red but the USB status indicates it is "supplying power to attached device" and the bat percent does not increase or does so very slowly. I started a case, it sounds like I may have a bad port on my phone. Motorola reports this is not a wide spread problem.
-Receive audio is sufficiently loud
Side key 1 and 2 can be user defined in settings (long and short press functions), options: camera, answer/end call, ringer/media mute or unmute, no function, OK google, answer call speakerphone, send status message (1-4)
All in all I like the phone, am very happy with the ruggedness and functionality and less so with the camera talkout audio and BT to APX functions.
