Bluetooth stability, range, and performance needed! - Android Q&A, Help & Troubleshooting

Our application is mission critical when it comes to Bluetooth SPP performance.
I was quite happy with the Tab 4 7.0 It worked awesome. Tab 3 Lite failed miserably at least the second version did. Early Lite versions were ok.
So since the Tab 4 is now Discontinued, I tried the new Tab A 7.0 and was quite disappointed. the Bluetooth connectivity is unstable and tends to crash so I have to turn bluetooth off/on, and the range is about HALF that of a Tab 4. Heck I can lay the Tab A flat on the table and it wont see anything!
So unfortunately it seems that Samsung isnt going to be a viable option anymore for us.
I need to know what is the best tablet for the money when it comes to maximum bluetooth range and performance? Thanks.

[Q] IR Blaster and speed questions

Hi,
I'm looking to buy a tablet s quite soon, was just wondering...
IR Blaster - does it get the remotes off the internet, ie. will remotes for new products in say 3 years time appear on the list, or will you have to use the learn ?
Has anyone tried it with a Pioneer 4280XD?
Speed - I noticed in Comet that it seemed a bit slower than the Asus transformer, might that just be something in the config or the number of apps running in the background ? Is it about the same speed in real life ?
Is ICS likely to make it run faster or slower?
Really looking forward to getting my hands on one.
thanks
For your first question, there is a preset list of brands and remote types included in the remote app. I don't think it has the ability to download more from the internet but that doesn't rule out Sony adding them via firmware updates.
Can't say for the speed of the tablet compared to the other ones as I've never used any other tablet.

[Q] Basic Phone for Wifi tethering

Hey all,
I'm getting myself a tablet instead of a smartphone as in my opinion they are the jack of all trades and the master of none.
So what I'm looking for is a basic phone that has great battery life as well as the ability to tether the internet to my tablet, anyone have any experience that may help?
My Tablet of choice is the Asus Memo pad 10
Thanks,

I've bought to my mom a Galaxy W, but at the same price you can now find the Galaxy Ace 2 (here about 170 Euro). You can then root them, improving the battery life. Wifi tethering works without root, just download a good app from the Play store.
get a galaxy ace...decent cheap phone which supports tethering
Have you considered bluetooth tethering? It's supported by non-smartphones (basic Nokia S40 models and others) meaning your phone battery will last far, far longer if that's your main concern. Android devices can definitely connect through others via bluetooth for tethering, you would just need to test non-smartphone handsets for compatibility.

Are there any bluetooth 5.0 headsets yet?

i need a replacement for my jaybird x2 but dont want to get the X3 now that bluetooth 5.0 is available. Or does anyone know of a good headset that will be release soon with bluetooth 5.0?
is it because your x2 doesn't work with the S8 ? because it doesn't work with mine either .

it works fine just the battery is getting old. and itll be nice to have more range with 5.0
I am also wondering if there are any Bluetooth 5.0 headphones anywhere yet. I can't find anything.
Also looking for BT 5.0. Still using the original Bluebuds x ! Battery only lasts me about 4 hours.
This is driving me nuts--there are some pretty legit reasons for wanting BT 5.0 headphones, and I don't really want to buy a replacement pair that DOESN'T have BT 5.0 because that'd be silly now that my phone supports it . . . blech. There has to be someone out there making them, right?
I searched pretty hard online this weekend and found NOTHING, not even articles/teasers of soon to be released 5.0 headsets.
I'm turning up similar amounts of nothing at all. One wonders why Samsung wouldn't be more interested in playing this up as a feature and thus driving stories about it. Maybe they're too focused on the AKG earbuds they're bundling with the phone, and the fact that the s8 has a headphone jack and the iPhone doesn't? That's my best guess . . .
BT 5.0 is pretty new. The S8 is pretty much the first phone to have it, and I believe it will take a few months until we see some better quality BT5.0 headphones on the market.
But no one's announced plans at all??? Finding the same nothing others are finding - and the silence is deafening.
FYI, X2 and X3 work just fine with the S8 and S8+.
I guess I will continue to wait. I actually really like my BT headphones, sound/battery wise, but they tend to cut out when my phone is in my pocket and I turn my head, which is just annoying.
The biggest issue with making devices that are BT 5.0 is that there is no backwards compatibility. So a set of headphones with 5.0 would not work on a device(Phone, tablet, computer,etc) that didn't come Bluetooth 5.0 capable. Sure they could add BT 4.2 to it, but that would require an additional bt radio. Increasing price and size
My Plantronics edge batteries are about shot. I'd love to buy another Plantronics edge like headset but I'll try to wait BT 5.0. Even if I weren't waiting for BT 5.0 I wouldn't buy another on the chance I'd buy a new headset that has been sitting around for 3 years.

Do you have source on this? I havent seen any articles that says it's not backward compatible. If this is true then it could be a while until any manufactures will release new headsets with 5.0 if the only device currently that can use it is the S8.
I'm not sure why you'd think they weren't backwards compatible. I've gone through every previous generation of BT and to the best of my recollection if you use a newer gen with older gen the only issue is you don't get all the benefits of the new gen but they certainly communicated with each other.

Look at the Bluetooth website. Or any other website talking about the technical specs. After I did research I tried looking up any devices that are 5.0, besides just headphones and sadly couldn't find any. 5.0 will be phenomenal, just gonna be a bit before it's implemented widespread sadly

Will Bluetooth 5.0 devices be
backward compatible with
current Bluetooth devices in
the marketplace?
Devices implementing only the
low energy feature of Bluetooth
5 will be backward compatible
with Bluetooth 4.2, 4.1 and 4.0
devices that also implement the
low energy feature.
Devices implementing the Basic
Rate/Enhanced Data Rate (BR/
EDR) Core Configuration will
be backward compatible with
all adopted Bluetooth Core
Specification versions beginning
with 1.1 that also implement
Bluetooth BR/EDR.
From the Bluetooth FAQ.
I can connect three S5 to my Bluetooth speaker that isn't 5 just fine. As well as transfer files fine.

I think you're mixing up what I'm saying. The s5 doesn't have bt5. But receiving devices that have bt5 are not backwards compatible with transmitting devices that aren't bt5. Majority of devices that transmit (phones, tablets, etc) will have bt5 and down installed in them, such as the S8, because doing that is simple. As a receiver has to implement all the things that come with higher BT qualifications and standards. Broadcasting BT is much more simple and convenient than having to receive everything connected to that signal.
I'm just relaying information from the bt5 specs though. I have not tested any of this in real world applications
That was a typo, I meant S8. Swype keeps using my old dictionary.
Here is the link I'm referring to as the FAQ:

wifi connection interrupts automatically when not using the tablet for a few minutes

Hey there!
Ever since the official Android 10 update I'm experiencing interrupts in my wifi connection whenever I put my tablet away for a few minutes. I'd guess that's probably some new feature for battery saving, at least it's called "sleep mode" on my OnePlus 5T, but I haven't found anything similar on my tablet yet. The patch notes for the Android 10 update also don't mention anything wifi or battery related as far as I can tell....
It's not my wifi since my phone and my bf's phone all work as usual.
Any ideas or anyone experiencing the same issue? Already checked dev options in the settings, but couldn't see anything related. Maybe I missed some settings somewhere?
Samsung Galaxy Tab S6, 256 GB LTE (SM-T865)

I've been experiencing problems with WiFi direct screen share connections too, like Miracast protocol

Yup! I did a couple of things though, so I don't really know which of them actually helped fixing the issue, or if it's even required to do all.
- I got 2.4 GHz and 5 GHz wifi. They shared the same name, which made my tab switch between them often. I renamed both wifis so they don't share the exact same name (fun fact, they're now called Pizza 2.4 and Pizza 5). My tab is now only using the 5 GHz one, the 2.4 one now is only for devices that don't support 5 GHz (like my New Nintendo 3DS XL or my printer), because I live in an area where many people are, and the more wifi channels are occupied, the messier (and more prone to interferences) it gets. 5 GHz has a smaller range but is also stronger, which is perfect for my small flat. On 2.4 there's way more interferences because it has more range.
- In my router's settings, I've set the tablet's IP to static, because I've read somewhere that this might help.
Can't tell if both steps are required, you might just wanna try out one first if you don't necessarily want a static intern IP for example.
My tablet also used to take ages to find my wifi, which is now fixed for some reason. On my OnePlus 5T it still takes very long to find my 5 GHz wifi, although it also has a static IP. But both devices won't disconnect randomly anymore.

bluetooth performance

As of March 22, 2021, the Bluetooth performance is buggy and quite bad. It regularly fails to playback any audio on first connection on a device, often needing several reconnects to said device to get it working and even occasionally and full system reboot. With certain BT enabled car stereos and portable speakers that I have used with my ZenFone 6 and Xperia 5 Mk1, no issues what so ever. With the ZF7, its a buggy and unfortunate experience.
Waiting on the Android 11 update to see if that brings the necessary fixes.
Will update review when that time comes.

Do you have any updates? Thinking of buying this phone and I use the Sennheiser TW2.
I switched over to a Samsung s20fe and i turn on and update the ZF7 every so often, and try it with my harman kardon onyx because i know it always gives problems with that speaker. I never had any problem with my ZF6 with the HK onyx. It still gives problems as of 29/08/2021.
