[Samsung Galaxy S10+ Questions & Answers] Manualeitor:
Hi to all.

First of all, let me apologize for my bad englisg/typos which may arise. My phone is the global version, Exynos chipset in 8/128 setup, buyed new 3 years ago and in pristine condition. I'm also a Senior Systems Engineer with a high background in hardware/software/telecom/SoC developing. I'm specifyng this to simply note I'm not a noob.

I'm a sight disabled person since 5 years ago, almost blind with a visual remain, that's why I buyed this handset as its screen was counted as the best of that moment.

One of the main things for which I use my phone is to auto detect and activate certain beacons, specifically the ones presentp in traffic lights (wich acoustically inform wether the light is red or green to safely cross the streets) and in bus stops (to know what's the next bus comimg), etc. For all this I need the device's BT set as 'always visible / discoverable'.

As you may know, beacons are auto activated when a BT device with a .DFA at the end of its name (i.e. 'Galaxy S10.DFA') enters his range. This way a blind person can walk around safely and obtain pertinent information with no need of manipulating the phone in every street crossroad, avoiding risks like someone stealing the handset or hitting and dropping the phone, etc.

I was using the free app Bluetooth Visibility Fix to have the BT set as always discoverable. Everything worked fine... 'till I updated to the last Samsung July 2022 Security Patch (released via OTA update somewhere between the 1st and 2nd August week). This update includes a 'Bluetooth stability improvements' item. From that on, it is simply impossible to use the app (or any other similar from the play store) to set the BT as 'Always visible'.

That made me feel totally dissapointed and of course fully discriminated. Not only me but I'm sure the ones who need this VITAL, yet simple adjustment just to make our lives safer and easier.

I'm wonderingn if there's an app blocking the BT settings that I can uninstall via ADB.

Or, if there's another solution that someone may think of.

Probably a downgrade would revert this situation, but I guess that solution would not be easier for my fellow disabled folks.

Also, I already tried the several BT settings within the Developer Options, but with no luck so far.

I'm circumventing this situation by carryng an old Galaxy J3 2016 configured with that app, but it is only a patch not a permanent solution, and not available to anyone. Note that many disabled people with a visual remains use to have top range Samsung phones because of the outstanding screen quality.

Please, I respectfully ask not issuing nonsense comments like blaning the big G, or 'it's a matter of security' or stupidities the like. If you're not part of the solution then you're part of the problem!

Having BT set as always visible has nothing to do with security. Any BT external connection request needs a explicit user permission in the form of accepting a pin code, etc. And anyway I feel that the way of setting BT is a matter that must be leaved to the user will...

Should I'll not be able to obtain some solutions on this, and being a member of the most important company of the world in terms of giving employment and support, not only to blind people but also to others with different dissabilities, I will publicly advise all of our members not to buy any items for such a discriminating company.

Please receive all my best wishes, and thanks in advance for whatever solution proposed.

Thanks in advance.
