Titanium isn't abandoned, but it's pretty close. It's certainly not optimized (read: barely functioning) on recent Android builds. I use Swift for my backups now. It's a bit clugey on the interface, but rock solid with backup/restore.
So, I'm over to the other side now. AT&T gave me a month's warning, then 2 weeks, then day of (but it was really the next day). I waited until the V30+ SIM card gave me error message it was no longer active to put the new SIM card in my Note 9 to activate it.
I'm on the rooted
Samsung Galaxy Note 9, which AT&T sent me. Headset jack, stereo speakers, back-of-phone (rear) fingerprint sensor. Still getting used to the bigger size and the weight. Much heavier than my V30+, which to me had the perfect size. (The Note 9 is even heavier than the Galaxy 10+, which I also have on hand but not using.)
Knowing the end was coming, over the past couple of weeks I used trio of methods to get everything over -- Samsung Smart Switch, Swift and Titanium Backup. Samsung Smart Switch was more basic and got most of the apps over. Swift got all the apps over and 99% of the data. Worked quite well. Just a couple of exceptions where it didn't, like my corporate email account data.
I then also copied over entire Titanium Backup folder (the zip file it creates to flash in TWRP didn't work) to my PC and then to my new phone. Trying to copy it over directly while both phones were connected via USB cable wouldn't work for some reason; had to use middle man of my PC Download folder, then
on to the new phone. In a couple of cases, I had to then "restore" data for apps from Titanium Backup. I had to completely reinstall Waze as it kept force closing when restored. Lost all my past locations.
I will probably pay for the Swift pro version and use that to make new backups, once I am satisfied everything is set up.
Advanced Power Menu (Noxx developer) doesn't seem to work but Recovery Reboot app does. Yeah, I know you can get to Recovery from Magisk, but I prefer a 1-click shortcut method.
It's only been a full day, but I miss the V30+. I miss the smart actions of automatically turning off Wi-Fi when I leave the house and turning on when I get back home. I miss the AOD automatically coming on when I lift the phone. On the Samsung, have to either tap the screen to see for 10 seconds or I can leave on all the time. So, I will tap the screen, I guess. I miss being able to turn OFF the screen with the same rear fingerprint sensor I used to unlock the screen.
Instead on the Note 9, I have to tap the power button the on right side to turn off. As a leftie, that means I have to use the other hand for no reason or awkwardly shift the large, heavy phone in my left hand to hit the side button, while not dropping it... On the LG, the power button, display off button, and fingerprint sensor were all-in-one. Design genius.
I found a website with LG V30 alarms, ringtones. There's a couple I used regularly so I downloaded them. I'm not going to restore any old V30+ "system" stuff from Titanium Backup on my Note, for obvious reasons.
I know I will miss the V30+ DAC. The Note 9 screen is big and it's bright, 1440K OLED. Yes, there's a headset jack. Has no notch. I will admit the back-of-phone fingerprint sensor is excellent and opens a split second faster than my V30+ -- but then the Note has more RAM and faster processor. However, except for the loud stereo speakers, there's nothing I see that's better
than the V30+, feature wise.
I had the stereo speakers hack on my rooted V30+ so having stereo speakers on Note 9 is not something new
-- except it's a native feature, not a hack.
Samsung Galaxy Note 9 has Dolby Atmos while the LG V30 (with root) had DTS:X. But the Note doesn't have the different surround sound profiles like V30 DAC (with DTS:X) had...
OK, one thing that is slightly better about the Note (one thing!) is the headset jack at the bottom of the phone instead of the top. I remember couple of years ago someone in this forum complained incessantly about the headset jack being at the top on the V30+. Now that I've actually plugged in headset on the bottom, yes it is nice not to have the wires poking up at the top when holding the phone.
the Note 9 is merely the best replacement available to me right now, to have most of the features I desire: Android, 1440p, headset jack, wireless charging, IP68 dust/water resistance, bootloader unlocked, rooted. But it's not a perfect
