After using this version I can definitely say that it's more laggy than 6.0. It tends to clutter and freeze sometimes, which is unacceptable for this phone's specs. 6.0 was way better. By now , the only thing I like about 7.0 is the number up. It may be a problem from the source code provided by Google.
1. After up-dating ceased to work for Android 7.0 the Phone application. In attempt to dial number through dialing unit the application is closed with an error after a set of the second digit. The installed other application works correctly.
2. Fingerprint was disconnected because of glitches on 6.0, after up-dating it was included. But in settings there is no point to on\off the sensor and there is no point of settings to include an unblocking on a fingerprint.
Yeah, I returned to 6.0. 7 is just too bug-filled. Fingerprint is s*it anyway, since the issue wasn't solved in 7, so I preferred to come back to a more stable ROM and to some of my favorite menu items, such as notification bar's "audio profiles". 7 looks good, but it lacks the fluidity and stability. Plus, I need my phone to charge faster. I'll be waiting for the improvements before returning to 7.
I have updated my UMI MAX to Android 7 via FOTA method. The phone is restarting constantly when connected to wifi.
I tried to flash it with flash tool (option download only) and it is behaving the same!
Could you give me a link for Android 6 rom so I can revert it back?
