Might be.. I was thinking about some fix for onekey (ultra power saving thing) thing in school.. will try and see

But I have no hide about fp gestures yet.. need to try again to decompile it
Hope you be successful in it. I am sure you can find some way for applying this. U have been a great developer for p2 and I really appreciate all the hard work you have done.

Best of luck..

I am using banking apps on this rom. There are no security problems.
Hi are you using tez on this rom. Because I am getting error from tez saying "tez cannot be used on this device" I am running official aex ROM and I have not rooted my device.

If you are using tez on this ROM please let me know.

I have a problem with the dual sim setup.
I am unable to disable the second SIM card, the second SIM is active and the GUI shows it as disabled. When you try to change it to active it times out and errors.

It has been already said in the thread not to touch that option.. it's just required **** for volte

Lord is back with another update. This is almost a perfect Rom now with bugs being taken care of one at a time. Many thanks.

Could you please tell if there is a way to put the volte icon back on status bar. It doesn't make a difference but just need it to be sure everything is working . Thanks for all the hard work.

There is no volte icon thing implemented in los sources yet so that can't be done..

so this is the procedure

Installation
Requires Unlocked Bootloader & a custom recovery
Place ROM & Gapps in your virtual SD
Reboot in Bootloader Mode
Go to "Recovery" (Vol +/Vol -) and confirm (power)
Wipe Data/Factory Reset
Wipe Dalvik cache
Install the ROM zip
DO NOT REBOOT
Install the Gapps zip
Reboot

I installed this rom yesterday it is a perfect rom

1. Volte works perfectly for me
2. Battery life is better than stock
3. Performance is far better than stock rom. The UI is very smooth
4. All banking app works perfectly on this rom. Including Google tez is working perfectly on this rom * i have not rooted my device*
5. Camera quality is same as the stock rom but as mentioned by other users video recording will not work with stock camera app, but using footej camera from play store will fix that issue
6. Sound quality is as in stock rom
7. Hotspot, Bluetooth, location services working perfectly
8. Fingerprint sensor works. But the gestures are nit working

Thank you for this wonderful rom

You should first make a buck up of your stock rom from the twrp menu. Thats for you own safety. If something goes rom it will be helpfull

And make sure you are on the latest version of stock rom (s244) because it is necessary for volte to work on this rom

Video recording does not work in system camera app? Why is that, Im just on the edge of unlocking my bootloader, but I want to be sure that it will be upgrade, not that half of features stop working.

It's a lineage bug. It works with footej camera app as mentioned. Right now The only bug is the fp gestures and the battery slider on the side. Otherwise everything works

    After watching all the reviews from others.. some are saying my ROM is half baked even if I tried a lot to provide usable build, still I failed..
    Some think my los build isn't fast enough so lemme tell I'll not provide further builds for los now..

    Wait for official one.

    I can understand that the behavior of impatient users is very demotivating. I have not installed one of your ROMs yet since I can't afford to spend time on trying ROMs on my daily driver which I use for work. I have been eager though to see progress on the ROM development for this phone, I have been keeping a close eye on development since day one. I know the effort you, as part of a team, put in to provide LOS to the same impatient users. But as demotivating it may be, don't give up on this device. Most users that appreciate the work done most are more mature and prefer to stay out of the mud slinging that we face daily on this section of the forums.

    Keep your cool, and know you are certainly appreciated, just as all the other developers like Mike working on a stable and official LOS for a phone that deserves a future beyond Lenovo's horrible planning. Regardless, thank you for your effort so far.

    * sim disabling: please ignore that option.. don't mess with it! It's just for volte to work, will be fixed soon

    * Video recording: it's not working properly so use footej to record.
