Thanks Oma, for being active in this!

Kernel #6 and #7 doesn't change anything, its still very usable and smooth.
Same issues as listed above.

Idea: for fixing the deepsleep dead, higher the lowest clockspeed from 126mhz to e.g. 242mhz?
Question: What about 5Ghz Wifi, hardwarebased the rk3288 should be compatible, i guess?

Thanks and have a great day.

Can I have a dmesg from a fresh boot? And if possible a dmesg from a running stock build.

Lowest clockspeed should already be 242 MHz.

As for deepsleep: pls check if the tab comes back pressing Power a few times. Need to know if this is only backlight or if the tab gets off. Also, if this happens pls reboot into TWRP and try to get last log (last_kmsg).

As for 5 GHz wifi install this via TWRP: http://crewrktablets.arctablet.com/?wpfb_dl=3063

Here is dmesg from fresh boot after 5ghz fix install:
https://pastebin.com/S3SzvTJ7

No more deepsleep death till now, tablet was idle for at least 4 hours, no death and only 2% battery drain - thats great!

Lowest clockspeed is displayed at 126mhz - it does going down to that:

Still no 5ghz or display bug?

Look into the CPU stats. You cannot set below 216 MHz.

Android 7.1.x has no option to switch between 2.4/5 GHz. So, I guess detecting apps will not work.

Use Wifi Analyser to detect networks. Option is there, but hidden.

I do not see any magnet sensor. I really need a stock dmesg. Reboot the tab before and use the sensor a few times.

[ 3.147701] D1:camsys_extdev_register(268): Extdev(dev_id: 0x2000000 dev_name: OV8858) register success
[ 3.165946] D1:camsys_extdev_register(268): Extdev(dev_id: 0x1000000 dev_name: NT99252) register success

As for the cams, they get loaded. What is or is not in Android?

Hi Oma,

yes you are right.
CPU lowest clock is 216MHz and 5Ghz Wifi works, thanks.

Camera Apps say: No connection to camera possible, maybe used by other application?
And Camera App Icon is hidden in app drawer.

Here is dmesg from latest 4.4.4 Stock rom with working magnetic sensor:

Info: Using "Switch" Button in Android Tool doesnt work on 7.1.2

For Battery recognizing right, change or add these values in your dts at battery part (ricoh619):

design_capacity = <6500>;
design_qmax = <6600>;

Or it would be very nice if you share your dts and your defconfig with me. 🙂

Have a great day

[ 0.773591] RICOH_FG_DBG: PMU: ricoh619_init_fgsoca : * Rbat = 135 mOhm n_cap = 4100 mAH

This here is the issue. Mini4 has 5600 mAh, right?

Unfortunately I cannot see any footprint of the magnet sensor in your KK log. Pls keep investigating on this.

As for Battery Capacity:
DSOC (Design State of Charge) is set to 10000, thats why android says it has 10000mAh.

As for Magentic Sensor, its not a dedicated magnetsensor, it's a hallsensor. Please include hallsensor compatiblity in kernel config.

AKM8963 is false.

[ 0.911241] sensor_register_slave:akm8963,id=29

AK8963 is right.

[ 1.188391] i2c i2c-1: sensor_probe: ak8963,0xdd6eae00

Thanks and have a great sunny day.
