[Samsung Galaxy Tab S8] SavXL:
I personally use an Anker 65w charging brick for my tab s7+ and s8+ and it works extremely well. Charges it at upwards of 5000mAh and only takes about 2 hours to fully charge. I also enabled an option to where the battery only charges up to 85% to protect it and make it last longer (it'll say the tablet is 100% charged when it's only at 85). The wattage of charger you have only affects how long it'll take to fully charge, but if you enable that 85% = fully battery setting (settings > battery and device care > battery > more battery settings > protect battery) then you should be all good.
[Samsung Galaxy Tab S8] lloydsw:
Thanks. Interesting that I changed my battery settings awhile back & it only shows charging to 85%. When I did the something to my S6, it would charge to '100%' as you said. I'm not concerned though, I'd rather treat the battery gently as they always seem to be the first thing to crap out.

is F21s Pro diffrent from F21 Pro? can you make TWRP flashable?
[Miscellaneous Android Development] azarok:
EDIT: I resolved this error by simply check a guide for SP Flash Tools. The required file was MTK_AllInOne_DA.bin

Thank you for the guide.

I'm stuck at point 3, when I try to flash the phone with SP Flash Tools, I need to add the Download-Agent file in order to proceed. I used all the .bin files in the rom folder but none of them work.

Could you please advise?

Thanks

Hi,

I successfully flashed the phone with the firmware LOS18.1-QJIN-F21PRO as the one attached failed during the flash process. My phone is the 3/32GB version.

I have two problems:

1) I tried to lock the bootloader (for security reason) but the phone never starter. (I imagine that cannot be possible)

2) The keypad light is always on, is there a way to turn it off while the screen is off? Which application/setting is controlling this function? I might be able to help :)

Overall the system is pretty stable, my next step is to install the MicroG. Any advice on this?

Thank you
[Miscellaneous Android Development] a9381:
f21s Pro is F21 Pro. it is the same thing.

TWRP brought in 4PDA (Thankful to @ Hagai that brought it in Mitamchim top - the Israeli forum). flash it as boot_a.

twrp.img

drive.google.com

What is LOS18.1-QJIN-F21PRO? This LOS for 32GB from 4PDA? It is based on my ROM.

You can not lock bootloader After Flashing ROM

Light in the keys? It's a well-known bug (number 4)

I now work on repairs, for example better support in hardware keypad.

​
[Miscellaneous Android Development] azarok:
Update: I managed to flash and access TWRP, but not able to find the MicroG zip file saved in the phone.

Hi,

Yes, I took the LOS18.1-QJIN-F21PRO from the 4PDA forum (I don't speak Russian).

I will try to flash microG through TWRP (thank you for providing it)

How would I access the TWRP on the F21pro? Is it sufficient to boot the phone with volume down (#/camera button) pressed?

Many thanks
[Miscellaneous Android Development] Jbazt_katuforzs:

[Miscellaneous Android Development] a9381:

[Miscellaneous Android Development] vanilla_milkshake:
Thank you for this! Any plans to upload the source? Would like to build this myself.

Instead of Gapps, MicroG would be awesome and less invasive (and easy to implement).

Please keep Lineageos clean and in the worst-case scenario, the user will install MicroG or Gapps separately.
[Miscellaneous Android Development] a9381:

[Miscellaneous Android Development] pwk pwk:
My English is really not nice.l am so sorry for it.A good news is that I can nearly fix all the bug.ways are as follows

First, we can use the data just by changing a file,/vendor/etc/fstab.mt6761,my version is 1.1.1, it's a little different from 2.1.6, but just delete words after "block,"except "," like me.and reboot to recovery, format data and reboot system to find you can use data

Second, we can make system writable by changing the same file .this time we should delete words "avb" except "avb" in this the picture below

Reboot and find it works .

Third,l find way to disable lcd bottom light.change to /sys/class/leds/mt6370_pmu_led1/

Find file brightness, copy it to sdcard change it to 0.and recopy to replace the first file.finally chmod it to 440,right now it works.

As the picture above.if you really need,l can make a magisk module to disable the lcd bottom light,too.both can make it works .

At last.By the way l highly introduce you to flash the lastest phh pixel experience a13 gsi, it's really nice,

I can confirm this works. And the battery life after disabling the backlight is amazing.

However, there is some bugs i found.

- no VOLTE

- auto rotate doesnt work in any video app.

But its now became a nice daily driver. kudos A.I.V for making a huge progress.

Can someone give me a link of this launcher? Thank you very much

​

Edit:

- The buttons backlight need to do every reboot

- Fixed the VOLTE for my network.

- The screen rotation on videos doesn't bothers me at all since I dont use this for media consumption.

Overall I'm glad I revisited trying out this ROM. Thanks a lot its now my daily driver!

battery usage since last full charged. Includes 8 hours of sleep phone just idle with backlight off

Hello guys,

I just found a local shop in my country for head unit and they installed the unit for me.

Everything was working except the 360 camera but they put a relay and now it's fine.

Spoiler content hidden.

I would like to change the interface I really don't like it,

I tried different Car Launcher but still not very happy..

I prefer to ask if it's possible before crashing everything (I did a backup in case)

I don't have any information about the vendor

Then if I understand I will have to choose between Mekede, Joying and Teres

Thank you for your help

You can just install launchers and uninstall them if you don't like.

You can toggle between the home launchers also in the apps default.
