Hi friends.
I broke my Umi Super LCD, and i wanna buy and install new Digitizer, but everywhere i see code F-550028XNX-C to buy. My phone have F-550028XNX-B - this "C" is suitable for "B"? and what is this code :S
Regards
This is new batch.
Only you need update firmware to latest as hardware needs new drivers.
The best option is to ask directly to seller for compatibles.
I also broke mine. I had a old type LCD and ordered the new one. It was plug and play for me because I have Android 7. BTW the touch screen works as good as with my Xiaomi redmi Note 4X . This way better than with the old touchscreen.
