Safe after July security patch??

Is it safe to install gcam after July security patch??

Will it wipe/erase all data??

Any suggestions will be highly appreciated

Thanks in advance
[Xiaomi Mi A1 Guides, News, & Discussion] taurelio:
Read op. It is safe if you follow the instructions. Otherwise you may loose all your data. So you choose...

There are two versions that are fully functional and stable:

-Arnova8G2 v8

-Arnova8G2 V8.1

Download link: https://www.celsoazevedo.com/files/android/google-camera/dev-arnova8G2/

There is no difference in quality between the two, you can choose either one.

To lock or unlock bootloader, in order to bypass the data wipe you have to keep pressed the volume down button.

See image https://www.dropbox.com/s/cstv6wz63mfk8rk/fps_drop_mi_a1_Gcam.jpg?dl=0 . If I choose recording in 30fps then there is more badly situation (3-19 fps).

if you do as all the post above have said , i think you will not get any problem ,

first set lockscreen on phote to swipe only , no patern pin or fingerprint, than enable developer option and there check oem unlock and usb debuging.

extract the dowload zip , than conect phone with pc ,( i'll recomend using the usb port from behind if you are on desktop) run the app as administrator and install driver 1.3 , than install gcam . it took around 5 min , phone rebooted to fastboot , showed twrp on screen , than rebooted again, configured the camera app as in picture and thats it . All went good, so try to do everything like this , and i think you wll not ave any problem. good luck :fingers-crossed:

[MENTION=8676627]AridaneAM[/MENTION] thanks for this. Followed post #98 for manuall steps, as i find it more straightforward.

And gcam installed perfectly fine!

I just wonder, why did this simple method take so long to figure out, as temporary booting twrp was known since ages i think.. maybe everyone thought, that OTA would rewrite the props again to default values, but as you have verified, its a win win. But even if we have to do this everymonth at the time of OTA, its worth it!

And i dont think why this wont work on other phones? The only difference i can think of, is that we are blessed with a phone that does not wipe data on bootloader relock.

It could be a dealbreaker for those phones that wipe data on relock. But apart from this difference, i dont see why these steps wont work on any phone!

Thanks for this once again.

Edit: and i just want to mention, when i followed the manual steps from #98 post, i did not disable my pin or fingerprints, and everything worked.

In the second step you have instructed to download adb/fastboot drivers. Opening up the download link, I can find adb drivers. But what about fastboot drivers? Are adb and fastboot drivers the same thing?

[Xiaomi Mi A1 Guides, News, & Discussion] MrJones2k:
slow motion is not working on our device with gcam, also not with root. So this is known bug and can currently not be fixed. In advanced settings you should be able to activate lens blur mode, but it overwrites portrait mode.

Hi

I am on Mac. Your tool is for windows, do you have something like shell script which will work like your windows installer tool?

I really do not want to install Magisk and then uninstall it. Since the source for your installer isn't available I believe if I try to replicate the behavior myself I might brick my phone, hence asking you directly.

Because I had gcam installed previously and when i did it the first time (in June) the phone was not actually wiped. Subsequently I wiped the phone and obviously wiped gcam also.

I installed GCam-5.1.018-Pixel2Mod-Arnova8G2-V8.3b1.apk but it closes on launch

This was done on Xiaomi Mi A1 AndroidOne Oreo 8.1 with Sept 5 patch

**UPDATE** I did get these steps to works second time. i gave up for a day. in the meantime i upgraded to october security patch. Then i remembered about security supposed to be disabled. so I did that. Then attempted quoted steps again. this time it did wipe when it says it will and continuing i was able to get it enable and able to install the gcam apk and use successfully.

GoogleCamera_6.1.009.215420794-beta2.apk (Arnova8G2, 2018-10-19 This one has yelloe tinge on front facing camera but its still beta.

I then reverted to Arnova's v8.3b1: GCam-5.1.018-Pixel2Mod-Arnova8G2-V8.3b1.apk (Arnova8G2, 2018-08-25 and everything appears to be working well
