I have a TCL A509DL phone that I want to connect a volume knob using usb otg. However, according to OTG checker it is missing the host xml file. Is there a way to add this. I know next to nothing about how this works. BTW, I use this phone to run a wifi app (Engine Driver) to run trains on my model railroad exclusively. Engine driver uses the volume buttons to advance the throttle. I want to add the usb volume knob in order to have a turning knob to advance the throttle. I have not nor do I ever plan to use it as a phone.
Thanks
Jim

Long story short, APK Installation is blocked on LG Classic Flip (no, it's not in settings). There is a way around it though: Decompile an APK, Go to androidmanifest.xml, change package name from com.example to com.android.cts.example (cts stands for compatibility test suite). It works beautifully for most apps, but some apps like Whatsapp are very protected and crash when I do that. Is there a way around that? Same with spotify.
On a side note, some apps aren't sized right for LG Classic Flip (Flip phone). LG Classic is 320x240 pixels. Is there a way to resize the apps (and not the screen).
I'm new, and I am not an expert, so please explain in beginner terms if you have the answer to either of these questions. I'm not stupid, and I learn very quick, I just am not very knowledgeable in this area. Thanks for your help in advance!, Shlomo Rabinowitz.

Thank you for telling me very nicely and I'm sorry for not reading that first, I'll make sure to next time.
Hi,
I have been looking for an adapter to let me use a USB keyboard and mouse over Bluetooth. To be clear I mean some kind of USB hub that connects USB devices to a system (Android phone/tablet in this case) over Bluetooth, without any gamepad or touch emulation. I just what something that passes USB devices over Bluetooth as if they were plugged into the system itself.
If any more information is needed just let me know.
Thanks,

Hi everyone - new member here, so maybe this has been covered, but thought I would ask anyway.
As we all know, the Samsung dialer enables native call recording from only a handful of countries and uses the phone's CSC code to make that determination. Other than rooting the phone - which trips Knox and potentially causes other problems and is super complicated for newbies, the only solution is to change the CSC code to one of those countries via a utility, which seems to work well from the posts here (p.s. third party recording apps cannot reliably capture the other side of the call).
The problem is that in order to even do that, you have to have a European model "B" or "E" phone - meaning, all lhe US based "U" phones are hopelessly without any solution.
My question is, why is it so difficult to hack the dialer into thinking the phone has the necessary CBC code that enables the recording, especially since it would appear to be a very localized and specific call for one piece of data that could be spoofed. I'm sure there's a very good reason why it can't be done, but thinking more along the lines of using a PC or Mac, it would seem simple enough to load some code at startup that would fool the phone into enabling the call recorder option.
Any thoughts?

Hello,
first of all I apologize in advance for my mistakes, but not being at ease with the English language I prefer to use a translator.
I just rooted this tablet with TWRP & Magisk.
Now I want to change some features in the settings menu.
For example, I want to prevent the user to delete an application.
I tried app locker to block for example termux but unfortunately you can still delete the desired application. Of course, app locker can't be deleted but the applications it protects can.
on the other hand, is it possible for example to switch the tablet to airplane mode from 9 PM and to grey out the functionality to avoid that the person reactivates the connections ?
Sorry this is a lot to ask but if you can help me it would be nice.
thank you and good day to all

oh I'm really sorry, and especially thank you for the referral
Hy guys,
I'm wondering, if there is a way to change the launcher-app, that gets started, if a HDMI cable is plugged in using USB OTG.
Samsung already added a HDMI-Mode switch from Screen Mirroring to DeX Mode. Maybe there is a hack to get my own app into this setting.
Example use case:
I want to display a game on my TV, when connecting it with my android phone, but don't want to run it on the phone screen. It would be nice, if it would start like Samsung's DeX directly on the TV. Or any other app like video surveillance or a chrome website.
In the next step I want to try using andronix+termux+vnc to get ubuntu on my TV screen while using my phone as android device.
Thanks for your ideas and inputs.
Kind regards,
Launemax
