Hello Everyone,

Right, I'm just going to give a quick intro to the situation TLDR below.
So I've been on android for a long time, ever since I got rid of my Nokia brick but my girlfriend has been apple since her first phone, so of course, I've been singing androids praises to her about the battery life, rooting and other such android brilliance, then a few months back she said fine but she had a few features she wanted mainly a big screen, removable battery, fingerprint scanner, and a good camera so after looking at loads of phones we settled on the lgv20, and then my headaches with the phone started.
TLDRGot my girlfriend who has been on apple her whole life onto android, didn't work out so great and now I'm looking for some help.

So the current state of the phone is
it's a H910 that was updated to oreo with a H920 kdx then dirtysanterd, then flashed with a rootable oreo rom and rooted with magisk manager, forgive me if I missed anything I did all this a while ago so it's not fresh in my mind and I'm pretty tired right now so il probable edit this later.

But the issues are weird and unlike anything, I have dealt with before so call on the knowledge of any LG v20 gurus for help, the first problem was present out of the box but did seem to get worse after all the flashing and rooting ect, the phone will turn off seemingly at random and won't turn back on until plugged in, and it will also do this if you try to take a photo with flash but not if you use the flash as a torch.

Now the second issue is due to being in the UK and the LG v20 being a US phone and was the reason I started messing with ROMs and rooting, the signal is terrible, I did check to see if this would be an issue before getting the phone and it seemed to be fine for others, but after having this issue and looking a bit deeper I have seen some people having the same issue with signal and having success flashing a modified modem, but I'm worried that it might not work and may make the signal worse, but if anyone has had success getting signal in the UK please let me know how.

Finally, there are just a few annoying things like some pretty heavy slowdown at times and some general glitchiness with apps freezing and crashing, so if there are any good ways to make the phone a bit more optimized and stable while keeping root that would be nice.

Thanks to anyone who reads this, and thank you to anyone who takes the time to share any knowledge and ideas:D

A lot of stuff there.

Flash issue sounds like a hardware problem but it could be software gone wrong.
Same for signal problem.

I would flash back stock Nougat *US996 KDZ (usa version) to see if the problems go away. Do not root and trial it for a few days.

This will also change the modem which might help signal issue. There is guide to cross flashing variants on this forum and youtube. Search *LGUP patched V20*.

So try this first is my advise.

*is best clean stock rom without network restrictions or bloat
