The same in Google photos, it would be great if someone will fix this bug! Thanks in advance
Yes this is also the issue which I forgot to mention. And please add a screenshot shortcut in qs tiles instead of power menu because it makes it difficult to take screenshot in hurry, also as my power button is wearing off it makes it more fragile. Thanks

Hi, I found a solution for the video bug! You have to edit build.prop in /system by adb! Heres the link how to do this: https://www.theandroidsoul.com/edit-build-prop-without-root-using-adb-in-twrp-recovery/

Please note, the build.prop is located in /system/system !! You have to seach for "audio.deep_buffer.media" under section ADDITIONAL_BUILD_PROPERTIES and set from true to false. From now on video in WhatsApp; Google Photos, etc works like a charm :D

Sorry, my bad! You have to search for another string:

Steps:

- Boot into recovery
- In recovery mount system
- Now connect with your pc
- Use this command for pushing build.prop to your pc: "adb pull /system/system/build.prop"
- Now edit build.prop and search for audio.deep_buffer.media=true
- Replace "true" with "false" and save
- Now use this command to write back edited file to your tablet: adb push build.prop /system/system/
then type
- adb shell
- cd system/system
- chmod 644 build.prop

That's all, reboot by using TWRP and test it!

I could not find the buil.prop file in the folder in which I am running adb fastboot after pulling the file successfully to the pc. Where should I search for the file?

I have now executed all steps successfully but the problem still persists. Any other solution? Any help will be greatly appreciated

Great rom, thanks for the amazing work. I installed this in 2 of my family tablets. 8704V and 8704X, working fantastic on both. Specially the 8704V, with only 2gb of ram it was getting sluggish. Even on that the rom is awesome, the tablet is back to life again!

I am excited to upgrade my Tab 4 8 plus to LOS 17.1. I am currently on LOS 16. I am having a bit of trouble.

I updated TWRP to 3.3.1 and did a NANDROID. Also backed up all my Apps+Data to the Cloud via TiBU.

First I tried a default wipe (data, cache and dalvik) via TWRP and than flashed lineage-17.1-20200607. I did a reboot and the device booted, but quickly went back to TWRP. I then wiped data, system, cache and dalvik followed by flashing LOS17.1 and gapps. Same problem where the device boots up but within 5 seconds, it boots back to TWRP. I also tried FORMAT data, but same problem.

Do I need to wipe boot? I downloaded the LOS17 file again, thinking maybe it was corrupt. No improvement. I am currently restoring LOS 16 via TWRP

This feels l familiar. It has been awhile since I played around with this device. I dont see anyone else reporting this issue here. Any suggestions on what to try next?

Exactly what model device are you using? A number of us with the TB8704F have reported reboot loop issues with any release past higwaystar_ru's second release on 2020-06-01.

Any subsequent releases from lancebuks go into the bootloop on TB8704F devices.

I am on TB8704F and will go back to the 2020-06-01 release. THANKS!

Update: I installed the 2020-06-01 release and micro gapps. Now my TB8704F boots up and does not crash.

Now I just need to figure out why Wi-Fi wont turn on/stay on. Any suggestions would be greatly appreciated.

Update2: I still dont have Wifi. I went back and installed the old Lenovo OS and Wifi worked with it. Should I be wiping the Lenovo System OS before installing LOS17? I did format data before installing the new OS. I cant get too far without WiFi, so any help is welcome.

Update3: I restored a NANDROID back to LOS16 and everything seems to be working fine, especially Wi-Fi. I am not sure what I should try next. Maybe dirty flash of LOS17.1 over LOS16. I know that could be unstable. I could try wiping data, cache and dalvik on LOS16 b4 installing LOS17. Any suggestions?

On 8704V,
1. BT doesn't turn on.
2. USB Type-C AC adapters with 5V~20V 45W output for don't charge the device. (They did with stock rom.)

Thanks for the port!
