That list was published by me on facebook (I forgot to add Crystal 2/16GB to the MT6737T line) but unfortunately UMIDIGI can't force MTK to do anything against their interests.
Actually the Super is the most popular model if that makes sense. Unfortunately the Helio X27 seems to be forsaken by MTK, but it already has received an Android upgrade.
I know, but it's really annoying. And now I have another issue. When I try to add a fingerprint, it just freezes and doesn't work.
I will format the phone and reflash the software with SPFT now, and I will update you to so if it worked.
So I just formatted the phone and reflashed the software. Because I formatted the phone, I lost my IMEI so I wrote it back. For now, the mobile standby issue seems to be fixed (maybe not for long?) and the fingerprint problem is also fixed.
I'm sorry but I can never answer 'if' questions, so I can't tell you if something happens, then what else will happen. Currently we have no information from mediatek about an Oreo SDK for the Helio X27, so there are no plans of such upgrades.
Look at my post at the page bevore. I have ask in facebook and make a Screenshot oft it for all that See it here . i have ask that umi update older phones like umi z .
