[Galaxy Note 10.1 (2014 Edition) Android Developmen] cstratz:
Hi! - My skills: I have a Galaxy S3, Note 4 and the Note 10.1 2014 and oftenly flashed stock rom or CM rom for the devices and know how to root them, from the beginning. - I know, that after changing between custom ROM and stock and vice-versa, I need to recover factory-settings and need to clear cash (ART&Dalvic) and cash-partition. - I always read instructions, before I flash a new ROM, like Lineage for the lt03lte. ...

... After a year with stock-rom, I now have tested the new LineageOS (nightly from 2017-02-22) on my P605 (DBT) - and have discovered these both errors with it:...

1.) Every time I log on to the start-screen, it shows me an error message like: "Settings are closed, do you want to restart them. [Yes|No]". It doesn't matter what I press then: always comes this big, white LineageOS banner "LineageOS" and logo on the screen (in front of everything) and neither the home-button nor the status bar, nor any other button can be used to do anything with the tablet. - Only the power-button offers "PowerOFF|Restart". After restart the same thing happens again: logging in with the number of my SIM card, scrolling up the padlock: boom!

2.) Charging my device in "OFF-mode" (complete turn-off) is not possible: the display only shows the battery with the flash in it. It never changes into the percentage gauge! - And it never turns off to black! - I needed to reset the P605 (pressing the ON|OFF-button for about 30 seconds) and then I see the charging battery symbol after Android v7.1.1 is already loaded and I am on the login-screen. ... Conclusion: If my device is off, I cannot load it (maybe it loads but not shows it). The screen then always is on! ("Battery with Flash within"-symbol.) Normal start of the device does not work, only long-pressing the power-button.

Also I have a question, regarding old battery-switch:

Samsung has had built-in a "cheat code" into its stock roms, called "BatteryStatus". You can open it with GSM code: "*#0228#". - Then, after pressing [QUICK START], -- if capacity is at 1%, -- (a new-) battery will be calibrated to the device and its installed ROM. - The lt03lte/P605 devices are so old, that changing the battery is not an unusual thing. ... Perhaps it then needs new calibration with the tablet? ... How can LineageOS do this job? - I assume, "*#0228#" and other codes will not work!? ...

And at last one more thing:

I am missing "Quick Charge" (v3.0 or v4.0) for the Note 10.1 2014!!!

... No just a joke! - It still stays a lame duck!

Okay, so far LineageOS for my P605 is for me unfortunately not useful for daily use. I only wanted to report these bugs here, because I am very interested in a working version until the end of this year, if this is possible... Greetings to all developers of this great, great new custom rom - and may they migrate it to as many devices they can! ... (My next devices will be from ACER ("Liquid Z630S"), a very interesting double SIM device with two SIM-slots and an extra SD slot, as well as changable 4000 mAh battery, - and in June 2017, or later, the new SONY Xperia XZ Premium! ... No way for Samsung anymore: only round screens, no innovations, holding back the Snapdragon 835, build-in batteries, fingerprint modules for aliens, and unfair treating of customers!)
