Is encryption a bad idea for app developer? - Other Tools & General Discussion

I have just bought a Samsung Galaxy S6 and I plan to use it for future Android app development.
I am also thinking of encrypting the phone for increased security. Is that a bad idea if I want to develop apps on it? Will encryption slow down the process of transferring and test running my own apps on it?
Grateful for insight,
Sven

Your question seems too broad. Encryption will certainly impact performance, but noticing this effect depends on what kind of app you are developing.

You may be right. It would be nice with the extra safety of encryption but I will probably not take the risk to try it (since I have understood that it may not be possible to turn off the encryption once tested).
Thanks for your reply!

[Q] What are your thoughts on CM Security?

For those who have tried it, what are your thoughts? Does it have good protection? How much does it impact your device's performance? Is it trustworthy?

I tried it and it worked well. But I'm personally not sure how well does it protect my system but it has to be good as it was ranked as no. 1 antivirus by AV-Test. It did not have any effects on my mobile's performance (it was good as usual).
I recommend installing least 2 antivirus programs on mobile. I use Avast!, 360 Security and CM Security.

Thanks but I heard you should only have 1 antivirus because they conflict with each other.

I know but I only run 1 at a time. I never had any problem relating to that.
Well I haven't analyzed outgoing packets to see what is leaking out or anything, but the privacy guard protections in CM11 at least partially work and maybe even work fully as expected. If you deny an app access to your contacts and then use a feature like sharing some data from within the app, you won't have any contacts to choose. If you deny an app using gps and try to use a function within the app that needs gps, the app will complain that gps is disabled and needs to be turned on. Just be careful not to deny anything in necessary core system processes. It seems like that is something you can do and it probably won't work out well.
What is missing, and is really a core problem with Android privacy, is a way to deny each app outgoing internet connections altogether.

I use android tuner pro to deny internet access to particular apps. It should be built in on every system but this works well as s far as I'm concerned. I think even the free version let's you control the permissions like that.

Smartphone without the "phone" part?

I almost never use my phone to communicate, and I have lately accepted and embraced my creeping paranoia. So, I'm looking for a device that does what my phone does, but without the phone, GPS, or microphone.
Does such a device exist? Is it possible to physically modify a smartphone to the same effect?

With root you can disable GPS, Phone and microphone

That means someone else can enable it via software too. I'm thinking more along the lines of physically disabling those components.

You can take out from the system these stuff and then unroot your phone. So no app can still install something to the system.

I'm kind of fixated on this idea of doing it at the hardware level at this point - I doubt it works that way but maybe get in there with a solder gun and pull some stuff out
Removing certain physical components would be a bad idea. If the device even turns on properly, you'll likely get crashes and FCs and whatnot. Even freezing/disabling certain functions like the phone can cause problems, since the ROM expects them to work. For example, being a phone, it has to be able to make emergency calls even without a SIM or service set up.
You could, however, use a ROM that lets you deny permissions to certain things (like calls, microphone, GPS). CyanogenMod, for example, or any of the number of ROMs that incorporate this CM feature. You'll have to disable them on a per-app basis, and you should always do a back-up first just in case things go awry.

Tablet having a plethora of issues

I'm beyond confused on what to do right now. The tablet is having problems left and right and Im just so confused, and no answers from Google are helping me.
Basically, I have three problems. First, the tablet cannot boot past the Nvidia logo. Second, the battery charges EXTREMELY SLOWLY. It took ten hours to get to 35%, and I fell asleep waiting for it to get one percent. And third, it discharges rapidly while on with the charger.
To note what I did, I installed TWRP, did numerous factory resets, and installed LineageOS. However, it just won't boot. Sp I am now here. Please help, I have no more options.

It's best to not update the OS ever. As long as it works. Also, Google auto update should be deactivated. In general, updates are bad. They take storage and eat performance in 80% of the case.

Regardless, this means nothig for the battery. I've also never seen updates ruin a device. For example, updates actually saved my phone out of brick.If not for Cyanogen, this phone would've stayed bricked.
OEM updates usual ruin the performance. That's my experience.
I've tried numerous 7.1.2 custom Nougat roms and have recently gone back to stock 5.2 and have to say that the device works a lot better.

70% of statistics are made up.
After the 5.2 update, my K1 is running a bit smoother/faster than before. Particularly screen rotation, opening keyboard, opening apps & going back to home screen.
Battery life is as it was before the update.
One of the previous updates (5.1?) similarly improved performance a bit.

Experiences will vary. But that goes with just about any software change, be it an OEM update, custom ROM, kernel, etc. For every person that says the performance, battery, etc. is better; there will be another that says it's worse.
There are lots of variables in how you use the device, what apps, etc.

That is the placebo effect.
I can only speak for my own experience. Why fix something that isn't broken?
Oh yeah! Newer version number. And there must be something better about it then. Maybe more ads, or more data tracking.. who knows? Well, the devs know.^^

Yes, the comments by this user are over-generalized, hyperbolic, and nonsensical. They add little value to this forum. Just sounds like a guy that had a bad experience once or twice, and now has an axe to grind with every update on every device. Ever.

Question Sounds issues on Exynos S22 Ultra (Ukrainian variant)

Hello all. I've got my Ultra on 22nd of February by pre-order in Kyiv, Ukraine (SEK variant, official reseller) and for a few weeks it was almost okay. But for the last 4-5 weeks I'm experiencing really weird sound issues with only specific games, but not all of them. Also all non-game apps are not affected. The issue sounds like the speaker is broken after hours of usage on highest volume (is like cracking). I've seen reports about similar issue but all over the system and it was fixable by reinserting sim card tray, but this doesn't help in my case. To give you an example of the issue - here are two videos which I've taken recently (the issue persists to this very moment): YouTube 1 and Yotube 2. Maybe someone can help me to finally get rid of it? The list of affected games (which I've found) is below:
Beatstar
Ingress
Rocket League: Sideswipe
Genshin Impact
Need for Speed: No limits
Microsoft Solitaire Collection
Thank you!

Tried that too before submitting ticket to Samsung support and it shows that everything's fine. Also Samsung support told me that these issues are not under their competency and they must be fixed by apps developers only. However, those games which I've mentioned are working just fine on other devices (including those which I've tested them on personally).
Yes it crossed my mind that it could be some incompatibility issue. Not much you can do

I'm just wondering how's it possible to be broken only on this device... Maybe some app can cause it...?
I've read elsewhere that opening/closing sim slot helps (and possibly turning off Dolby/Atmos)? At least for awhile.
I don't think it is broken as it only affects some games as you said. Which I interpret that there could be some incompatibility between game and hardware. It should be looked by both Samsung and game dev but .....
also, it is not just your device, there are reports of it happening on other S22s too

As for those workarounds - yes, they are not helping, unfortunately. And about other reports on S22 series - I haven't seen any about some specific apps, only general ones where people tell that their phones sounds like that overall, even when they're just out of the box.

Privacy on chinese phones

Hey there,
I've been using my Realme 5 Pro with an ungoogled custom ROM for a while now, and I felt safe until I saw a video from The Linux Experiment (Videolink is with timestamp):
In the video, he mentions that he no longer wants to use a Chinese phone because China might force the manufacturer to install spyware. I know that The Linux Experiment is very skilled, but in this case I am not sure if he is a little bit paranoid. ^^
My questions are:
1. Is it possible for Chinese companies to spy on a phone with an open bootloader, custom ROM, and custom recovery?
2.1 I have already read that backdoors on the hardware side might be possible. Is this true?
2.2 How high is the risk of this happening?
2.3 What Information can they get with a backdoor on the hardware side?
3. How concerned should I be, because getting a phone without chinese influence is very hard?
Thanks for your help.
PS: I don't want political discussions. Just the technical view on my concerns, which are my personal opinion.

Is it really worth the effort? wouldn't a Hardwarebackdoor mean, that you only get machine language which has to be processed and sorted?
For a very important device like the phone of a president or minister that might be a practical solution but how much work is it to do that for a massive amount of people?
Thanks for your answer!
