As xiaomi mi 8. Mi 9 have dual GPS based on Snap 855 chip. But i just want to know how accuracy it can be?
Can you guy do some GPS Test and post here ?

What do you mean by dual GPS?
All GPS uses multiple satelites already to get your position, and Android further gets a more localized position by then pinging you off wifi networks as you pass them. The unclassified GPS bands we are allowed to use are accurate to around a dozen feet, technically we can be no more accurate that this. But with tricks like wifi scanning the phones do get around 4-6ft accuracy.

I am unable to get gps location on my mi 9. I am using chinese version in US. what am I missing ?

sorry, chinatown ? I dont know, how do I get to it ?
I ordered through giztop, they said its a chinese version with google play store. but they didnt say anything about gps not locking.

forget it, it was a joke.
try in location settings to high precision

:facepalm:, I didnt get the joke earlier
also, I have the location settings to 'device only', but unfortunately, the gps is not locking. no fix. I am using 'gps status' app to view the status
Can get down to an accuracy of 3m on device only mode when I'm lucky, and 5 meters on average

Thanks,

It same on mi 8. No 30cm accuracy like Broadcom said about BCM47755 gps chip in Ad

30cm accuracy might be in laboratory kind of conditions... 3m is defnitely still far enough for real life usage though
EDIT: Also read that the chip can be used not only in smartphones... Phones have small antennas, 30cm might be for car GPS and such who have far bigger antennas and space considering its their only utility

Can anyone tell me the touch screen latency of Oneplus 3T. Higher latency was the only deal breaker for me with One plus 3 which was 95ms.

You don't realize until you know it. But once you know it, it is difficult to use phones with high touch screen latency. Check this out:

I don't know how to calculate it but you can estimate it. Enable show touches in developer options and try to drag your finger around. See the YouTube video for better estimations.

Using the video you posted, latency falls between 10ms and 50ms, but closer to 50ms.
BTW, OS 3.5.3 update for the 3T specifically addresses high latency issues.

SGS Touchscreen Booster app does wonders for other androids.
Someone try it and report back
Also Note 4 has an option to increase touch sensitivity in the pull down menu.
Is there an option to do so on the OP3T?
It's pretty sickeningly quick/smooth coming from the galaxy s5, if I say so

That app says "Only for Samsung Galax S up to Android 2.3.x."
App Link to SGS in Google Play
I think the sensitivity of the panel is something different, as it would be more based on being able to detect soft touches.
Nothing scientific of course, but it didn't seem noticeable to me at first. I'm coming from a LG G4 which doesn't appear to have the best latency in the first place, according to this post on Reddit. Since all the posts came up about it I've started to notice it slightly, but nothing that hinders the user experience. Maybe in other cases it's more apparent, but so far in my day to day use it hasn't been an issue.
It works in later phones.
Use it on my note 4.... and it helps improve the touch experience

How is GPS performance for daily usage? Some people mentioned poor GPS quality for mi a1. Does mi a2 perform better?
Sent from my Huawei Mate S using Tapatalk
It's all good.
Gps quality is indeed garbage. Mine won't work despite I tried literally every possible solution.
No problems with GPS for me

If you are on Pie, go to security&location, location, google location accuracy and turn off Improve locatuon accuracy.
When I turned it off gps work really nice.
For me its very good, its even using galileo so fast and precise.

Haven't upgraded, I'm waiting for the OTA, which is taking forever. I'll try it and see. Thanks for the reply!!
How do you rate GPS in this phone?
I am considering it as my next phone but I've read in a review at notebookcheck.net (sorry, can't add links) that GPS quality for navigation is very bad. What do you think ?
GPS works perfectly. Better than Samsung J5, or Redmi Notr 5 and 6 Pro.
I use Google Maps, Waze and AutoMapa.
I use Google maps and uber a lot. No issues whatsoever gor me.

My phone is also too bad.... It's not accurate
No problems with GPS whatsoever. Works really good.
I see some people have issues with the GPS on this phone, but I have not seen any issues at all.
I feel as though when using it for navigation it can be slightly behind causing me to miss turns on islands or getting into lane early enough
Someone point me towards a good measurement app (ruler) that works flawlessly on Oneplus10 pro, the one's google suggested aren't good enough
To measure what? Like a ruler? Or measure battery?

Oh it is a ruler.
Crikey, im really not sure buddy.
I think if it works well enough, then one of the AR rulers sounds amazing. If they work. I think it depends on how big the thing is you want to measure (not entirely sure where my trail of thought is heading at this point, I'll keep it clean)
For accuracy I'd say honestly any of the ruler apps.
For much larger things, cars etc, it has to be augmented reality, although I would fear the lack of a laser on the camera system would prohibit accurate defining of distance.
So personally from this knowledge I'd say any of the non AR apps.
Download a bunch and test them
Hello!
Does anyone know if it is dual Gps compatible? Does the GPSTest App show L5 or E5 satellites?
Thank you very much!

According to this source (pcmag), "s23 ultra" doesn't support dual-band GPS. Make conclusions yourself.
But using the app "GPS Test" shows the reception of L5-signals. Does this mean they are being used?
Yes, the S23 has dual band support and uses the signals of those satelites.
On the other hand it does not use "carrier phase". My impression is, its location data therefore is a bit less accurate compared to devices that use carrier phase.
