Is Substratum safe to use? - Samsung Galaxy S9 Questions & Answers

Hi!
I'm interested in trying Substratum theme engine with the Andromeda plugin, however I've been reading through Google play reviews and some people were complaining that the app cause problems with their devices such as bootloops and crashing. Is it also the case for the S9 or it's completely safe? I'm using the latest firmware version on my exynos S9. Unrooted.

What's "completely safe" mean really? If you apply substratum themes not meant for your phone you'll bootloop. Just like any other mod, it's as safe as you make it. If be you read and follow directions you should be fine, but like any hack it's a risk you need to be willing to take.

wifi Roms for SM-T807P

Hello XDA!
I recently purchased a SM-T807P (10.5" LTE/Snapdragon) with the intent to use it as a wifi device.
Will anyone tell me which roms work with this device? I've heard the challenge is to find a snapdragon rom?
Its rooted with TWRP on it already. Just need some tasty roms to play with.
If there is ANY way to get cyanogenmod on it that would be my first choice (I would even be willing to offer a bounty!)
I am already running the only one I could find specifically for SM-T807P.
[ROM][TW][SM-T807P Snapdragon] SuperSkilled Basic ROM V1 + Firmware
http://forum.xda-developers.com/galaxy-tab-s/development/rom-superskilled-basic-rom-v1-t3055473
I'm glad to find a custom rom, but am really for a lollipop de-bloated rom.
But ANYTHING that people have tried so far would be great.
OR anything that I should try that wont permanently brick my new tablet!
Thanks all!
Now you have twrp just make a full backup before you go messing and you'll never have to worry about bricking your tablet.
As for roms, pretty much all roms are based on stock, so just modify yours as you see fit.
Debloat, add mods, etc.

Considering that I am using a snapdragon version of this tablet maybe you could point me in the right direction about which roms work for that processor versus the other?
I know one of the issues was finding a rom that had the right kernel for my tablet.
No the kernel isn't the issue. Its that the t807p is partitioned differently than what the available ROMs are compatible with. I have the same tablet and as awesome as it it, there is very little support for it. No developers have it and its very difficult to work with without owning one.
There is twrp available which I assume you have used and rooted. There is a stock ROM on XDA that is lollipop that works awesomely. I just debloated it myself and tuned it with kernel tuner with stock rooted options. Xposed won't work without a deodexed rom either which is not available. But regular root options and a different launcher (I use nova) and i have it running pretty damn smooth.

I flashed the only KK ROM I found and got FC's to no avail. I then basically wiped the whole thing then odin'd to lollipop. I am stock now and you're right, it's a damn nice device. -- I wouldn't mind de-bloating it myself, do you by any chance have the 'safe list' to reference as far as which apps are good to go. Last thing I wanna do is get rid of some odd-ball system file that creates hell for myself.
Thank you
Just make a backup first with twrp before you go messing then use system app remover to debloat or just freeze with titanium backup . If you get an issue after removing something you can easily restore it.

No problem. First off, listen to everything xda senior member ashyx says. I have been dealing with my rooted t807p for a while and I have found all his posts on the tab s not just accurate, but extremely useful.
here is a post regarding safe apps to uninstall: http://forum.xda-developers.com/galaxy-tab-s/help/list-bloated-apps-to-uninstall-sm-t700-t2861180
Now what I have personally taken off my tab s has been the superficial apps. The magazine apps, office apps that I have no use for, While a lot of apps on the post may be safe to delete, it doesnt mean you should if you plan on using your tablet for wireless transfers, casting and what not. I prefer not to touch many of the "behind the scenes" apps. And also it depends on why you are debloating. Are you looking for more storage space? or for better ram and performance? Unfortunately, at least for my use, you wont save much storage space by deleting apps. But freezing them and playing with it makes a big difference. On just a standard recent apps clearing and maybe a push of my "fast reboot" app, and I can get my RAM to run at around 900mb and little battery drainage.
I hope this helps. Let me know if you have any other questions, I have played with my t807p for quite a while with rooting and have learned pretty well what works and what doesnt. I am no developer like the senior members on here but there aren't many people with our specific tab s.

I realize it's been a year or more, but do you have a link to the Lollipop ROM for T807P? I've tried the "SuperSkilled" ROM but it was KitKat. I looked for a Cyanogen build for this tablet but no luck. Looking for any ROM that's close to AOSP or at least debloated and is Lollipop or MM.

Couple of questions about Pixelizing Xiaomi Mi 6

Hi All, I purchased my Mi 6 like half a year ago, and I asked some questions with regards to this device back then (reference: https://forum.xda-developers.com/mi-6/help/xiaomi-user-issues-actual-issues-t3703112 ) . I then gave up for some time, but would like to revisit some of my initial issues with the device.
DISCLAIMER: I am not very knowledgable on Xiaomi stuff, this is my first phone from them. I owned it for around six months and I still didn't root it... I just didn't see any _worthy_ rom to be installed. Please bear in mind, that although I am technically savvy and rooted all my previous phones always, I might sound as a total noob here since I didn't follow the scene very much.
At present, I have requested the unlock with Xiaomi, and they granted me the possibility to root the phone, but I haven't done so yet.
I am thus running on stock MIUI 9.5.6.0.(OCAMIFA). The Android is 8.0.0. OPR1.170623.027.
What I would like to achieve, is to get my Mi6 as close to current Pixel devices as possible. I understand that I could purchase the Pixel phone in the first place, but the price tag on them is too high..
(I am mostly interested in having the most recent version of Assistant available on my Xiaomi, and Pixel UI instead of MIUI)
I am unable to install Google Phone.
When I visit google store from PC, I can search for Google Phone, but can't install it. https://i.imgur.com/21fh9hq.png (and the reason why it's not compatible is not being disclosed). If I search google play store from the device itself, the app isn't even listed in the results. If I download any version of the Android Dialer app from APKMirror, and try to install - the installation would start, and then fail with a single message (App not installed https://i.imgur.com/gOolw3H.png ). I tried ARM, ARM64, both in NODPI and other DPIs, also, I tried app versions 19.0... and 20.0... from https://www.apkmirror.com/apk/google-inc/google-phone/ . Always getting the same error.
What's interesting, is that I was able to install Google Messages, Google Contacts and any other google app without any problems, but I can't install the Phone app from google. I have also been able to install rootles-pixel-launcher from APK
I am left with the phone app from xiaomi, which is not integrated with Google Message / Contacts apps, and vice-versa.
I am looking for the clear up the following doubts:
1. Anyone experienced problem installing the Google Phone ?
2. Any idea how to further debug why I can't install Google Phone ?
3. Are you aware of any up-to-date rom giving me the pixel experience (The Pixel Experience thread has a lot of people askingn for updates - is it dead ?)
4. I start missing my LG Nexus 4, did I purchase the wrong device for what I am trying to achieve with it ? I start getting the feeling that I picked a phone with not enough scene going for it. Or is the scene in China?
Sorry for lengthy post, and appreciate any input.
cheers
You need to flasy Google Framework, then you can use googles apps like "phone"
Install any AOSP based rom, flash Gapps, root with magisk and search the download section for the 'Pixel 2 experience' module. I chose the last launcher, "new custom launcher"
Check if camera2api is enabled. It should be because of the pixel experience module but if it isn't yet download a magisk module for enabling it.
Check the Gcam threads on here for the recommended Gcam APKs and make sure to install Google photos too.
Last step is install the magisk module "Google framework" and installing the phone app etc. from the playstore.
After I followed these steps any AOSP based rom feels very pixel-like and Gcam even makes me think I actually bought one from time to time
Edit: I'm starting to think the pixel experience module actually has the framework included already as I currently don't have the framework module installed and I was able to download the phone app without any problems.
Good luck!

I've been a member since my first ever android device, HTC Wildfire Mini. I've rooted and installed custom ROMs since back then. Ever since grabbing my self a Pixel device I felt all my needs were catered for, until now.
I miss managing my standby time battery using Greenify and a custom kernel. Not that I don't get great standby time on my phone currently but I feel the itch to get tweaking again. haha oh I miss Viper4Android
I was wondering:
1. Can I still have root access and use Google Pay/mobile banking apps?
2. Xposed framework, is that still a thing? haha I used to love those little tweaks.
3. ROMs, what's everyone using?
4. I've not used Magisk before, can anyone point me in the right direction?
Thanks,

Welcome Back!
1. Yes, google pay and most banking apps work but I believe it depends on what bank you use. (I use Chase)
2. Xposed is questionable at best for the moment, at least for Pie. It's still in beta for 8.1 and, as far as I know, Rovo89 hasn't mentioned any development in that regard
3. Personally, I prefer stock. I use elemental kernel, magisk modules and substratum.
4. Magisk is simple enough to use, but some have had issues since Pie. To get a general idea of how magisk works, start here: https://forum.xda-developers.com/pixel-2-xl/development/2017-11-6-root-pixel-2-xl-t3701176

1. I personally don't use any banking apps for making payments but from doing some reading it seems most will work as long as you don't have the Xposed framework installed.
2. It is a thing up to Oreo. It is still in beta for Oreo, however when I used it I had no issues. It felt stable as far as I'm concerned. However, it did slow down my device a bit and I also found alternate apps for the Xposed mods I used.
3. I'm on Liquid Remix and I love it! HavocOS is really great too. I've been a long time Flash kernel user, but now that is EOL. I have now switched to Kirisakura.
4. You just need to download the Magisk zip from the official thread and flash it in recovery. After you reboot you'll see the Magisk Manager app and it's pretty straightforward and self-explanatory at that point!

Installing microg over Lineage questions

Hi all. Please forgive me if this is not the appropriate place for my question, and kindly point me to where. I tried to look for a microg targeted thread and couldn't seem to find one. I'm also kind of a newbie in general, so you may have to be a little verbose with some of your responses. I made sure to read microg's official docs on how to install over lineage.
My question comes in two parts; 1. Do I actually need to do this for my specific case? and 2. For my specific case, is there anything specific in which their official instructions might not cover.
So here is what I keep referring to as "my specific case".
My device is a OnePlus 7 Pro. I had LinageOS with microg 17 on it. Things worked great. Including microg. I recently upgraded to Lineage 18, as per their official documentation for how to upgrade major versions. Well, I was so focused on not bricking my device because I was so nervous. As I said, I'm a newbie. Much of this is out of my comfort zone. I wasn't paying attention to the fact I was using lineage's zip/img/rom that I was installing, and not the microg one specifically. I had many other complications with the upgrade and was tracking all of those down. Now, things seem to generally work ok, but there are many apps giving me issues because of no google play services. At first, some would just alert me, and then keep working. So I just kinda wrote it off, and figured this was just an issue with version 18 or something. They had an OTA update the other day, and now those apps just flat out won't work anymore. At first it didn't even cross my mind that it was because I installed the img from lineage's repos, and not microg's specifically. Because I still have the microg app installed. I will note, from reading the "Post-install" section in microg's documentation, I don't see the two plug-ins which they say are installed by default. MozillaNlpBackend and NominatimNlpBackend. So I feel like this is because I installed the non-microg img.
As I started searching around for how to fix my issue, it's basically led me to the point of my first question. "Do I actually need to re-install the microg specific img?" I think the answer is Yes. But I just wanted to confirm since I still have the microg settings app, and for a little while, some apps worked prior to this last upgrade.
So, if the answer is yes to my first question. My second question, is there anything specific I need to do since I kinda fudged up the upgrade? Do I need to uninstall microg settings? I noticed in microg's install instructions under the "Migration from LineageOS" section. They mention things such as "you can't directely flash our ROM on top of the official LineageOS while keeping your data". So does this mean in my case I can't keep my data? And there is a specific note for "Unofficial builds" of all the apps that I had such as F-droid, and microG's apps (GmsCore, GsfProxy, FakeStore and mapsv1 API). I had these, but they were from the official lineage 17 with microg I had prior to the upgrade. So those are not "Unofficial" right? As well as their mention of "GApps". Does that mean everything I installed through Aurora Store?
I basically want to know if there is any other "gotchya's" or "in your case, you should x y z" type of questions. I think it's clear that since I did just OTA update I probably need to wait on the next release as per their install instructions. Right? Let me know if there is any other details I can provide in order to help better answer my questions. Thanks in advance for your help.
Your case is not so special. Flash lineage.microg.org zip

Thank you for your response @kurtn. So I guess you are saying, I do in fact need to flash. Correct? And I don't need to uninstall the microg settings app? Also, do I need to prepare for backing up and saving my personal data even though their documentation says it can't carry it over? And I don't need to wait for the next version even though there documentation says I do? I'm sorry for the newbie questions. I just want to make sure my assumptions are correct. TY
I just fixed my issue, and tested pretty much everything. It all seems to be fixed and working as expected. I will answer my question in case it helps someone else.
1. Do I actually need to do this for my specific case? Yes
2. For my specific case, is there anything specific in which their official instructions might not cover. No, not really.
I waited for a newer release before flashing the microG version of LineageOS. I'm not sure if it was required or not. But since their official documentation said to, I did. Then I followed their official instructions, and everything worked flawlessly. I've tested all apps and services; phone calls, texts, etc. It all seems to be working just fine.
@kurtn was not wrong. All I needed to do was flash the microG version of LineageOS. But since I was hesitant, and wanted confirmation specifically a few details like; Do I need to backup personal data? Do I need to wait for the next release? etc. I held off on attempting it.
Hopefully that helps someone.

Question Impact of Installing Custom ROM and Reverting to Stock Firmware on Galaxy S22 (Exynos Variant)

Hello XDA community,
I am considering installing a custom ROM on my Samsung Galaxy S22 (Exynos variant) and would like to gather some information regarding the implications of this action, especially if I decide to revert back to the official Samsung firmware later on.
Apps Compatibility: Which apps will no longer work if I switch back to the stock firmware after installing a custom ROM? I understand that tripping the Knox flag by rooting or installing custom ROMs can cause certain Samsung apps like Samsung Pay, Samsung Pass, and Secure Folder to stop functioning. But what about other apps? Specifically, I am concerned about the compatibility of my banking app from Belfius (Belgium) with features like contactless payments.
OTA Updates: Will I still be able to receive Over-The-Air (OTA) updates once I have installed a custom ROM and then switched back to the official firmware?
I understand that the Exynos variant might not differ significantly from the Snapdragon variant in this context, but I thought it's worth mentioning.
Any insights or experiences that you could share would be immensely helpful. Thank you in advance!
So first thing you need to understand is that you would be installing a GSI and not a fully maintained device based Rom.
That means forget about the timely updates.
Secondly, GSIs are not optimized for particular phones and you might encounter bugs. From what I remeber, VOLTE won't work on GSI and for some phones even Bluetooth audio and mobile Hotspot won't work. Not to mention erratic battery life and unoptimized system.
App compatibility won't be an issue. But you have to say good bye to the samsung ecosystem. Also, if you do decide to install a custom rom, you will trip Knox and a few apps like secure folder, Samsung pay, samsung pass and Health might not work (unless they are patched). As for banking apps, they should work fine unless you are rooting your phone. If you do, you just to install a magisk module to pass the play stone security settings (forgot the name of it).
Also, if you again decide to go back on the stock rom, you just need to relock the bootloader and you should be able to get Ota updates again.
Overall, it's a good experience but you will grow tired of the bugs present in the GSI soon.
