1. Are there any privacy and security concerns on the using the Gcam port, it seems proprietary to code of Google why would they just give it away for no money or data from its user in return? Its not opensource also right, can we have strict controls on it with privacy guard(any screen shots on the camera settings option from privacy guard would be appreciated)

2. There a couple of system apps whose purpose to access data is unknown ex - Theme font colors (Tomato, Pumpkin, lavender, Forrest ,cyan ,dark), ProxyHandler, Settings Suggestion, Profiles Trust Provider etc. is there any consolidated list where the purpose of each of these system apps reason for interaction with internet is mentioned? (STILL WAITING ON AN ANSWER ON THIS)

3. Any solution to my initial question of tap fingerprint senor to wake phone? it was a pretty neatly implement in MIUI but not present in LOS 16, any reason for its absence? (NO ROOT SOLUTION WOULD BE IDEAL)

Currently I'm on latest LOS rom and I want to flash the latest vendor, do I need to format the data partition?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] dalyer:
No.

Just flash the vendor/firmware and maybe wipe cache/dalvik (may not be required but never harms).

If you previously flashed dfe to avoid encryption then you need to flash it again each time you flash vendor/firmware.

But if you already use encryption then no need for dfe.

I never use it myself.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] ziglar24:
dfe or not

Just wanted to understand that if you dont flash dfe, how do you install updates to the kernel etc. Because when I skip dfe, I cant access TWRP to install. It asks for a password, without which I cant see any local storage files. Or do you always complete wipe when updating a kernel.

This will be very helpful as I dont want to flash dfe but have to for kernel updates and other root related stuff.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] dalyer:
I don't flash dfe and use the official twrp from twrp.me and have no problems flashing stuff.

If it asks for a password try your pin/pattern or maybe even "default_password" (without the quotes).

I dont get asked for any password.

The last time I updated my vendor, I didn't flashed DFE and as a result lost everything on my internal storage, I hope the same doesn't happen this time
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] dalyer:
In that case you must have flashed dfe before (or used orangefox which applies it unilaterally without asking) so your phone was unencrypted, then flashed new vendor/firmware and it encrypted and you "lost" your data in that you could not access it in twrp or maybe elsewhere?

As I said if you never use dfe then just flash vendor/firmware and everything will be fine.

If you ever used dfe on your current setup then you need to flash it again after every vendor/firmware flash.

And, as ever, backup stuff if you are afraid of losing it!
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] TheFirstGladiator:
Just read a blog to flash LOS on poco and followed as the guide as it was reliable, didn't know it was going to be concern later, What would have happened if the user just flashed LOS and the vendor firmware without DisableForceEncryption_Treble to begin with?

Not clear on the purpose of DFE, also could you confirm if your internal got cleaned up just because you missed to flash DFE or every time you flash a different firmware there is data loss?

Thanks in advance.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] theandroidguy:
Well DFE simply stops the device from getting encrypted, and IDK why I've problems while decryption so I choose to flash DFE. If you just flash Vendor+Rom then your phone will get encrypted and everytime u restart your phone you will need to enter key to decrypt the phone and if you forget your password then you will require to format your data partition as well as Internal storage. Now what I follow now is Flash vendor+rom+DFE, and if you want to change rom, clear data partition from TWRP 1st then install Vendor+Rom+DFE, reboot to system and then boot in TWRP then flash gapps. Right now I'm on OOS
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] TheFirstGladiator:
1. If the user hasnt setup a lockscreen pin/ password/pattern lock, will the phone still get encrypted? This DFE seems to be only for the ones who setup a password on lock screen, else no need to flash DFE while flashing a custom rom?

2. If the user itself has set the password then they can type it in the recovery(TWP) when its asked right, so I dont get the purpose of DFE flashing, it just seems like a way to over ride a security feature right?

3. Just figuring out this OS, on the multi tasking window(taping the recent apps button), in MIUI the user could see the ram usage there, how to enable in LOS?

4. "OOS"?

Thanks in advance.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] dalyer:
Oxygen OS
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] theandroidguy:
Well I'm not a big fan of encryption and 2-3times I lost my data because of this, so I prefer to flash DFE and moreover I'm not accustomed to this thing.

No idea abt multitasking options on Los, used LOS for a very small span of time.

OOS is Oxygen OS which got ported for our Poco from the Oneplus 6, the best rom I've used till date, awesome performance, stable and good battery life

Firstly, any reason OOS over LOS?

Were you able to tap fingerprint senor to wake phone in OOS? It was a pretty neatly implement in MIUI but not present in LOS 16, any reason for its absence?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] dalyer:
[MENTION=2934546]TioCareca[/MENTION] already answered your questions!
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] droidjunky90:
guys please refrain from asking the same questions over and over again and do some research, this thread has millions of dozens of questions, with that being cleared of the way lets start here:

1. it's always recommend to remove any security locks (fingerprints، PINS, Patterns, etc) and sign out of google accounts, before flashing any ROM or even Dirty Flashing any updated ROMS, DFE is to be flashed ONCE in the case of first time installation of TWRP using ADB commands on your PC, the reason why it's recommended to remove the passwords to prevent data loss, and lets say you don't want to remove them, its your own risk you will be prompt to type the password on TWRP.

2. is covered in number 1, it doesn't override any security its to be flashed once upon TWRP installation.

3. as far as am concerned this option isn't available LOS is s custom ROM and doesn't replicate the stock MIUI ROM.

4. Oxygen OS which is a Custom ROM.

Will we get widevine l1 in LOS?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] dalyer:
Flash MIUI beta 9.2.25 boot/activate/configure it, get to launcher, install DRM info from play store, wait a bit then check DRM info and it should be L1.

Then reinstall twrp, ROM etc and L1 certification should persist.

There's a twrp flashable zip of MIUI beta 9.2.25 in the "unlock, root etc" thread in the Poco F1 guides forum.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Damoedge:
I think you just need to flash the firmware/vendor that includes the L1...not flash the whole Rom ?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] dalyer:
No, you have to flash the full ROM.

Just vendor/firmware doesn't cause L1 certification to happen.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Damoedge:
That's not what they are all saying on the telegram group or the MIUI forum

Also it does not matter if your phone has L1...the phone itself has to be certified by Netflix and Amazon or any other streaming media company that provides full HD...it's just like the Android TV boxes for example the Nvidia shield ?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] dalyer:
Just flashing vendor/firmware didn't do it for me in pe caf.

I had to flash the whole rom temporarily.

Obviously now that my phone is certified I can't test again.

Anybody else got it working by just flashing the vendor/firmware?

If so I'll stand corrected.

Change phone app doesn't work

I would like to use another phone app (los 20022019 and firmware 9.2.25 with fk r20). Rom phone shows forwarded phone numbers concatenated with the number of forwarding phone I.

[[[If you just flash Vendor+Rom then your phone will get encrypted and everytime u restart your phone you will need to enter key to decrypt the phone ]]]]

I have an encrypted phone and I don't enter any password when I restart.

I disabled all pin pattern and password in the phone - so I restart without entering pin or password or pattern.

The phone will encrypt without the need of you setting these.

There is a default password it uses -it's called "default_password"

Only when you're asked for a password in TWRP and you haven't set a password or pattern yourself, you can you use this "default_password"

---------- Post added at 02:31 PM ---------- Previous post was at 02:22 PM ----------

Back up your data.

Do a factory reset.

Boot into official TWRP (install it if you haven't done so)

Install vendor firmware

Wipe cache dalvick cache system data internal storage)

Install a ROM + gapps

(I discovered that some roms install their own vendor firmware so you might have to reinstall install vendor firmware after the rom)

Boot into phone

Boot back into TWRP

Install magisk

The idea of encryption is if your phone is stolen the thief guy cannot access your data into the Android of your phone.

Encryption needs are password so if you don't provide one it will use a default password.

As far as I know and in my experience you have to flash the full 9.2.25 rom, get L1 certified and then you can go back to custom ROM stuff.

Just flashing the 9.2.25 vendor/firmware did not do it for me.

And newly flashed vendor/firmware will always encrypt unless you flash dfe if you really don't want encryption.

This latter piece of info is posted on an almost daily basis so anybody who loses their data because of encryption only has themself to blame for not doing some basic reasearch/reading.
