Alright, some more input:

1. Magnetic Sensor - you know
2. Displaywakeup is slow as hell, sometimes it doesnt wake up (only display)
3. Batterylife is very bad, around 2h SOT, maybe lower.
4. Kernel has some stuff we dont need, we can make it smaller, and decrease the boot time
5. Reboot from Android to recovery sometimes makes kernel crash (last_kmesg comes the next time)
6. Camera changes ratio when zoomed.
7. Switch button in android tool wont work. (adb is good)
8. Please change touch-update-frequency to every 3 or 2 pixel (now is 6 i believe)
9. You are a very good person
10. Profit

Thanks oma.

Not really.

Waiting on another users feedback to finalize the touch. You corrupted your touch controller by flashing a strange firmware into it. All what can be done is to "half the touch" which has the reported side effect.

As for other issues pls install the latest Ifive Air v1.2.4 build: http://crewrktablets.arctablet.com/?wpfb_dl=3060

with the latest Mini 4 kernel (change in folder rockdev/Image before flash): http://crewrktablets.arctablet.com/?wpfb_dl=3095

and the Mini 4 model fix (install in TWRP): http://crewrktablets.arctablet.com/?wpfb_dl=3097

For reporting battery stats pls use BatterySpy (see Play Store). Let Android learn the stats at least two cycles before reporting back.

This is not really right.
If i flash the stock firmware, touch behaviour is very very different, so i guess, the parameters can be adjusted in either dtb or kernel itself.

For battery drain, it comes from wifi driver/handling, if i disable wifi - battery life is much higher than with wifi.
(With Wifi on Battery Drain at night is about 20 - 35% - with wifi off - drain is about 2-3 %)
And yes, is have the option to disable wifi while sleeping enabled.

Thanks anyway oma, i guess i can be satisfied, that android 7 is usuable on my device.
But not satisfied, that kernel sources are not public - but thats not your fault.

Alright, atm testing.

Here is last_kmsg from random kernelcrashes at reboot:

https://pastebin.com/XMSFG9Ez

<6>[    1.276895] dwmmc_rockchip ff0c0000.rksdmmc: DW MMC controller at irq 64, 32 bit host data width, 256 deep fifo

<1>[    1.277032] Unable to handle kernel paging request at virtual address f00004fe

 

BTW: Charging the tablet sometimes takes about 15hours, sometimes only 3-4, with original 2.5A charger, suggestions?

Is this really the untouched Ifive Air v1.2.4 build running?

As for battery stats, this is not enough information. Pls let me see the stats as plotted in settings/battery and BatterySpy app.

Yes this is the Air 1.2.4 Build. Why are you doubt of?
Will give you a graph, if enough data is collected.
Battery seems far better with patched kernel object.
Nightly battery drain today was about 5-8%

Update: Batterylife in idle is really bad... i got 30% drain in 4 hours with wifi on with only batterydetector running in BG.
Update1: Sound in games like "Real Racing" is stuttering, while 3D performs fine.

Hello,

Thought my venerable IFive mini4 ( still alive!) was no more updatable, and the saw your post. Could not believe it!

Finally after some brainpain could install LineAgeOS 14.1 succesfully. Only issue I see  is that GPlay Store is no working. gets freezed. Also cannot access to Google acount to log in. Looks like G Apps are not working well. Rest seems ok so far.

How can I reinstall GPlay Store app?

 

Thx so muchSmile

Hi Oma ,

Yes , I installed post #1, Kernel is 3.10.0 ( read on tablet info). build 1.2.4 09/06/2017. Is this ok? or better Ifive Air v1.2.4 build with IFive 4 mods ( post 33).

 

Finally could install GApps via TWRP and GApps downloading Mini option, 7.1. Now I can access to all Play store  apps etc. Perfekt.

The only gap so far is that camera does not work. Shows "could not stablish connection to camera". I installed Cam Fix via TWRP install, but no way.

Should I also install "Mini 4 model fix (install in TWRP): http://crewrktablets.arctablet.com/?wpfb_dl=3097" option?

Thx so much, and excuse "newbie" questions.
