Recommendation for a device that can lock on LTE.

Greetings
I have a need- locking device on LTE only.
The need is for testing in my workplace.
I would like to buy a device that I set it to this option easily, without installing ROM, etc.

can you give me a recommendation for a specific device, Specific Model and a Specific Android version?

I came across a number of online forums and posts-
were not conclusive regarding the specific device/ Model/ Android version:

Many thanks in advance

Recommendation for a good file manager.

As the sony does not have a default file manager like LG or Samsung, what do people use, can you recommend a good one that is ad free.

[App Recommendation Help] Gallery & Music App which are similar to Xiaomi Mi3

I just switched from a Xiaomi Mi3 to Moto G4 Plus and I want apps for gallery and music that are similar (if not the same) to Xiaomi Mi3. I have downloaded a few off the playstore but I am not happy with them. Right now I have QuickPics which is OK but the issue is that it doesn't play and view both images and video within the same folder. And for music I have the paid app of PowerAmp but it isn't reading my SD card and the overall feel of it is not like the Xiaomi inbuilt player I had which was VERY smooth. Are there any alternatives for me?
Thank you in advance.

Powerbank recommendation?

If you use a powerbank for your Shield which one can you recommend?

I tried an Aukey Quick Charge 2.0 16000mAh but when charging the k1 the stereo speakers make a high pitched noise. :(

I tested a Power Theory 10000mAh and this one works fine. Downside, only 1A input.

Next I'll test a Quick Charge 2.0 by Anker.

Bill Reminder application recommendation

Hey guys
I used billminder for years and years on IOS and I was happy to see that it was also available on android. I installed but unable to login to pull all my info into application. Seems it hasn't been updated since 2013 and no longer supported. I am looking for an application to keep track of bills and provide charts overtime. Anyone know of an application that runs on both android and ios for bill reminding?
Thanks in advance.

Request for ROM recommendation

Just got a 5X (in the US). I would like to use the fingerprint reader (so probably limited to stock ROM?) but would also like to use Xposed if possible,

Could someone recommend a ROM to flash? Or can I put Xposed on stock ROM at this time?
