If your screen still is working you can go to settings - about phone - build number and compare to this firmware versions numbers http://community.umidigi.com/forum-134-1.html
So if your firmware is not latest and your touch not working correctly you can use OTG adapter and connect computer mouse to your phone and check for OTA updates (settings - about phone - wireless update - check for updates).
If your phone doesn't see update but you are not on latest one you can follow OTA zip file update (local update) http://community.umidigi.com/forum-134-1.html
Don't forget that the any OTA update needs to be done one by one.
Also you can use SPFT and flash phone directly to latest firmware.
Here is instruction http://community.umidigi.com/thread-2962-1-1.html
About screen with or without frame.
I replacing always without frame but if you don't know how to replace easier repair is with frame.
To remove screen from frame firstly apply transparent tape over broken glass then remove top and bottom cover, screws, remove back cover, disconnect and remove battery and other stuff, use hairdryer to heat up screen on edges to soft double side tape and remove screen from frame. Reuse old double side tape if you don't have correct one.
You can check on YouTube how dismantle phone.
Is there any new information? I have also F-550028X2N-B LCD which is broken. Can I use F-550028X2N-C instead of my old LCD?
I can't find where tu buy F-550028X2N-B.
You can buy any screen dedicated for this phone. If you have problem with screen after replacement you need update using OTG wire and PC mouse or SPFT.

Ok, I answered double...so You sugest buying any or the one offered on Alixpress and then do the update, in terms that I do not yet understand, but will hopefuly find what that exactly means..
I see that there is some screen replacements with "frame" for the double price, and without it for about 20-30$...
How to tell if I realy need the frame...? It seems undamaged, seriously, scratches and little damage..I think it will fit the new screen, but I have not opened the phone yet, it is working almost to the full with the broken glass..
So should I take it to repair man to open it and see the frame condition, maybe send a photo so you UMI guys can make some judgment on that?
