[Google Pixel 3 XL Questions & Answers] DarkPhoenix:
I'm just curious if anyone has the option to enable Chat Me in the Messages app? Everything I've read says that it's available but there's no option to enable it in the Messages settings. I'm using an unlocked Pixel 3 XL from Google on the Verizon network.

Here is a link talking about the new feature from July of this year.

https://www.google.com/amp/s/9to5go...ogle-android-messages-rcs-chat-explained/amp/

Here is the link in Google support that talks about the feature and how to enable it.

https://support.google.com/messages/answer/7189714?hl=en
[Google Pixel 3 XL Questions & Answers] bsg411:
There is no chat me ...its just android messages. The chat features only work if you phone provider supports RCS.....and as far as I know...neither verizon or AT&T support the feature on the google phones. Thats why the option doesn't appear in the messages settings.
[Google Pixel 3 XL Questions & Answers] DarkPhoenix:
The only reason I asked is because Verizon supposedly has say it supports it.
[Google Pixel 3 XL Questions & Answers] bsg411:
I think all the phones on that list has "agreed" to support RCS but havent altually implemented/provisioned it yet. The only carrier that I think it works on is sprint.....for now. Hopefully soon though.

I have started to experience GPS not being able to lock about a month ago. It sometimes locks and works fantastic, but when it doesn't, it's very frustrating, especially when you are trying to go to new places...

I have tried resetting the phone, purge GPS assistance data, flashed the latest firmware, but nothing works.

I have searched online and found several people complaining about the same thing, which leads me to think that it's a hardware problem that cannot be fixed.

I am thinking about getting a new one just to see if it'll have the same problem because the phone is just perfect for me.

Small form factor, side fingerprint scanner, dual speakers are just perfect.

Can any of you think of any other things that I can try to fix the GPS?

or do you think the hardware of my phone is damaged?
[Sony Xperia XZ1 Compact Questions & Answers] andTab:
I have the same issue. It usually resolved after slapping the phone. I wonder if the GPS chip or antenna is loose …

sometimes I can get it working by rebooting but slapping it seems to work better.

Very, very annoying. Otherwise still the best phone ever!
[Sony Xperia XZ1 Compact Questions & Answers] CAPS_LOCO:
I've spent over 1.5 hours this morning looking for a solution to the same issue, and this thread is where I struck gold.

I love Sony compact line, but having to slap the phone to fix an issue is just ridiculous.
[Sony Xperia XZ1 Compact Questions & Answers] Didgesteve:
I came accross this problem on my XZ1c, but I found a different fix.

Go into airplane mode and make sure GPS is disabled.

Settings\Apps & notifications\App info - find Maps

Force stop - Storage - Clear cache - Clear data

Restart phone

Enable GPS, airplane mode off.
[Sony Xperia XZ1 Compact Questions & Answers] efaustus9:
Same situation here myself, tried all the solutions (even slapping) to no avail. I really like the phone but a fundamental feature such as GPS not working is unacceptable. I am going to try to get a replacement from sony but if this problem is pervasive as it seems then I may be in a similar situation again in the future. Seems like Sony bought a bad batch of GPS chips when they put this handset together, if I get a replacement I might just sell it, go back to the x compact and bide my time for the xz4 compact.
[Sony Xperia XZ1 Compact Questions & Answers] ben53:
Hi

I had the same issue. Five days ago it worked fine but not yesterday. The GPS toolbox application found more than 20 satellites, but no one was fixed.

It was not the first time. I think the issue appeared for the first time after android Pie update. But I notice that I had a firmware update the day before yesterday.

I found a temporary and immediate solution right here when the GPS does not work at all. It comes from the sonymobile web site but I cannot post the link, sorry :

You may find the subject "XZ1-Compact-GPS-not-working-after-Android-PIE-update" on the web site talk dot sonymobile dot com for XZ1 compact

I did not have to reboot my phone. I just launched the GPS location test right after and it worked fine and quickly.

It seems that the sequence may be repeated every week. It is too soon for me to say so.

Hi

I'm noticing GPS problem also. My XZ1 compact is still on Oreo . I've tried the solutions stated previously (except slapping it). The phone has been slow to aquire 3d fix and seems to have trouble keeping a signal. I've been using GPS Test Plus on my phone and on my cheapo Lenovo Tablet, and what I found out was the tablet got 3d fix much faster, accuracy on tablet was better (1 -3 meters compared to 3-14 and often much worse on my phone. SNR (signal to noise ratio) is in the 20's and 30's on the tablet and is in the teens and barely gets into the 20's on my phone. I thought GPS worked better on phone previously when I first got it, but this is the first time I did this kind of comparison and maybe it was always like this?
[Sony Xperia XZ1 Compact Questions & Answers] efaustus9:
I found a solution although it essentially confirms it is a hardware issue. Taking the phone out of the case and squeezing the top left SD card and SIM card bay door restores the GPS, not long after letting go the GPS will drop off again. I did this numerous times as I drove out to the relatives this Christmas Eve and it worked every time.
[Sony Xperia XZ1 Compact Questions & Answers] handasan10:
Weird actually thinking having this problem after last Pie update..
[Sony Xperia XZ1 Compact Questions & Answers] handasan10:
After using apps like GPS locker and GPS fix from playstore, and putting aluminium foil in between the case, I manage to fix GPS temporarily and sometimes after restarting.. This all sometimes not working and as my compact covered with 2 years extended warranty, I just send it t Sony for board replacement..
[Sony Xperia XZ1 Compact Questions & Answers] Didgesteve:
9 times out of 10 it's down to cached data error

I came across this problem on my XZ1c, but I found a fix.

Go into airplane mode and make sure GPS is disabled.

Settings\Apps & notifications\App info - find Maps

Force stop - Storage - Clear cache - Clear data

Restart phone

Enable GPS, airplane mode off.

If that doesn't work use the following service settings number to go in The gps settings :

on your phone keypad dial *#*#7378423#*#*

Go into service tests, select gps then purge test data

Or just give some complete stranger teamviewer access to your phone.
[Sony Xperia XZ1 Compact Questions & Answers] handasan10:
Yes sometimes this fix do works. But I also figure out this is hardware problem after using gps locker app. When you squeeze the phone on upper left the signal is higher and you got instant gps lock. But when you leave the phone, the signal drops and you got very low accuracy when using gps, sometimes you missed the turn..

I have with all my xperia problems with gps. I have GPS data installed by propane apps .First A-GPS data download then fix. Work 4me for xperia z3c z5c xz1c.
[Sony Xperia XZ1 Compact Questions & Answers] TheArt.:
Can you explain further? I have a xz1c which drops gps sometimes
[Sony Xperia XZ1 Compact Questions & Answers] n2hearse:
After trying all the of the stuff I've found on the internet (all software related, seems nobody has opened the phone to check or resolder the antenna) finally the only tweak working 100% of the time it's and external GPS antenna.

Still have the "GPS status" app installed to easy purge cache data, and sometimes seems to work, but when you really need the GPS it ****s you nor doing restarts, or whatever trick you remind.

I've bought a cheap second hand Holux M1000 bluetooth antenna, and now I've working gps when needed.
[Sony Xperia XZ1 Compact Questions & Answers] Dean F:
Hello everyone.

My phone started experiencing this problem now for 1 week. Its now impossible to do my running with the phone, as the GPS keeps constantly connecting and disconnecting. The data it collected after my run is not usable.... this was working fine for 2 years, then suddenly this has started. Already tried clearing caches, using 3rd part app to reset GPS data - all not working. sucks.
[Sony Xperia XZ1 Compact Questions & Answers] Dean F:
This the what the GPS problem looks like

[IMG="XZ1 compact GPS fail"]http://1drv.ms/u/s!Aj3RXwrQWx2ggp5FbUHM_AqGDWfrLw[/IMG]

For those who are wondering what the XZ1 Compact broken GPS problem looks like. Basically, one day your phone suddenly starts doing this.
[Sony Xperia XZ1 Compact Questions & Answers] messenja:
Same problem for me. Everything went well until yesterday. It happened on my XZ1C Pie, then a tried to purge data and clear cache, but nothing. Then rolled back to Oreo and still same problem. Sometimes it works, but more often it doesnt. I use GPS very often and now i have to buy one more device
[Sony Xperia XZ1 Compact Questions & Answers] Dean F:
Same, I also need buy a new XZ1c now. I use GPS often for Strava.... one of my biggest use cases. So frustrating.
[Sony Xperia XZ1 Compact Questions & Answers] messenja:
Addiction found

After a few days of searching the reason, i found following: when i remove the cover case (made of silicone) of my phone and get the phone in my hand it works perfectly, it locks about 20-24 sats, but when i put the phone on the car panel, for example, it stops working (locks about 3-4 sats o stops working at all). So the problem may be in poor sheilding on the motherboard, i think. Anyway, don't know for sure until open up.
[Sony Xperia XZ1 Compact Questions & Answers] Dean F:
3 people on this thread have hinted at the problem being near the Sim/SD card door. Either removing the door, squeezing the phone int he area, etc.

Guess what helped me? I removed my SD card ! and the GPS suddenly went back to normal. At least we can all say - the problem is in that physical area of the phone.
[Sony Xperia XZ1 Compact Questions & Answers] huzi7868:
That did not work for me and does anyone know how to set gps to high accuracy cant find the setting
[Sony Xperia XZ1 Compact Questions & Answers] strate aero:
Well I've been dealing with this GPS issue too and trying different tips here that work for a while but then the problem comes back. However I just tried another tip I found at talk.sonymobile that seems to show more promise. I cleared all app caches related to location and then put the phone into ultrastamina mode for a while and put it back into normal mode (which restarts the phone). GPS improved right away and so far a day later is working better than before. It's still not high accuracy or quick to lock on but it's better than I've had it for a long time.
[Sony Xperia XZ1 Compact Questions & Answers] albenex:
All software "solutions" are placebo, maybe leading to a slight improve over a definitely low quality signal which is caused by hardware issue.

I too experienced an huge improvement by using custom ROM (unofficial LOS 16.0) but nothing similar to first-year use experience where GPS insta-fix with a rock solid 3m errors showed on GPS Status & Toolbox and similar softwares.

I've also tried various slapping/squeezing "fixes" with no joy..

my phone is out of warranty so i have to choose between opening it seeking for a real hardware fix or mantaining its waterproof feature... very hard choice
[Sony Xperia XZ1 Compact Questions & Answers] Gamer_1:
My problem is volte not working on my phone, so i flashed so many fw-s to work. After i recognized my GPS not working well. My phone didn't find satellite and if find with very low signal.

So i used the XPERIA Companion software instead of newflasher and clicked on the software repair, now the gps working good, in building my phone find so many satellites below 20 second without mobil data or wifi.

Try it, maybe help.
[Sony Xperia XZ1 Compact Questions & Answers] czrtst:
I had the same problem with the GPS - nothing from the tipps helped really - so i also used the sony sompanion software and made an software repair - GPS now working again - navigation in the car works again -before impossible.
[Sony Xperia XZ1 Compact Questions & Answers] rlsimon:
What about XZ2c ??
[Sony Xperia XZ1 Compact Questions & Answers] brodo:
Hello,

I had problems with GPS reception, too, on my xz1c running HavocOS (Android 10). Since I originally assumed a hardware issue, I bought another used xz1c and checked explicitly that GPS is working fine (quick lock and good accuracy).

Before unlocking the bootloader I did the usual treatment (as described in [XZ1c/XZ1/XZp] temp root exploit to backup drm keys implemented): Downgrading to 47.1.A.8.49 (without persist file while creating a tadump), getting temp-root, backing up TA partition and upgrading again to Pie (47.2.A.11.228). Somewhere along this path I broke the GPS again and it seems to be as bad as on my first xz1c.

Meaning: on good external conditions it can get a lock but it takes very long and the accuracy is bad and also fluctuating very strongly (between ~10m and ~100m). My older z3c gives me 3-5m accuracy under same conditions.

I'm pretty sure that it's not a hardware issue this time. I tried downgrading again, restoring TA partition, restoring tadump, reparing with Xperia Companion but to no avail.

Many ppl reported GPS problems after upgrading to Pie. Could it be that an update (or whatever tampering with the device's firmware) wipes calibration data stored in the persist partition that is device specific and cannot be brought back?
[Sony Xperia XZ1 Compact Questions & Answers] hockeymikey:
Hmmm, that is an interesting theory and may have legs. I have similar performance between my two xz1c. They run the same rom and get similar GPS performance. Leads me to think it is software like you said. Tempted to buy a new one and play around with it and see. Can we backup the persist partition and restore it?

I have one and it locks instantly. Are you having issues?
[Sony Xperia XZ1 Compact Questions & Answers] brodo:
Assuming the persist partition is the culprit here... GPS should work after flashing a firmware via newflasher or flashtool without persist_X-FLASH-ALL-42E5.sin file. And it breakes after upgrading to a more recent firmware. I haven't tested this though.

Btw I got the idea after skimming through this post where under "6. OTHER PARTITIONS" it says

What I don't understand is why the GPS receiver should need such important data (I mean is it normal that a GPS sensor needs calibration data?) which can get lost so easily, even after a standard upgrade procedure like many people here reported.

And if this data is so unique to each device it wouldn't help to restore a partition from a functioning device as far as I reckon.
[Sony Xperia XZ1 Compact Questions & Answers] hockeymikey:
Maybe. I will investigate with the new device. I don't know why all the calibration data would be needed or be goofed up on upgrades. Was the new device you bought new or used? I'm honestly leaning towards hardware again. I've been having issues not locking at all for a few weeks and I fixed it this weekend. What I did was hit my phone on the lower back of the device while holding it from the top ear piece using my thumb and finger. I had to hit it just right and you can tell after the right hit it locked again and can get down to 20ft of error and more hits could screw it up. I mean the gps is still garbage taking awhile to lock but it's usable again. Maybe it's hardware and software. Software that limits the performance/accuracy and a hardware that can further degrade it.
[Sony Xperia XZ1 Compact Questions & Answers] martynas:
I also have same problems for last year. But recently noticed that squeezing the phone in the midle (height) on right side i get back fast and reliable GPS lock. When stop squeezing the signal halves or being lost. As I use GPS only for cycling - now just use 2 clamps on the area when cycling. Looks stupid, but works. When I drive car and use Waze/google maps, than these programs use internal car GPS and also no problem.

PS sent for repair describing the problem (+ to replace battery), paid 70 EUR, received a notice that problem was fixed, but after getting phone back see that GPS was not fixed...

PPS using stock Oreo 8,0...
[Sony Xperia XZ1 Compact Questions & Answers] hockeymikey:
New device came in and it performs the same as my older one. Very bizarre. Either an older device and I"m being duped or this is software.
[Sony Xperia XZ1 Compact Questions & Answers] martin_sz:
I had same issue back in the days - could not lock to satelites.

As it was in warranty I had it repaired - they claim they changed motherboard, battery and display.

Now the problem is starting to appear again.

Does anyone one it is a hardware piece that could be changed - like gps antenna or something like that?

I only found Signal Antenna, but I suppose that is for 3G/4G and has nothing to do with the GPS

[Sony Xperia XZ1 Compact Questions & Answers] hubert-bangol:
I found a hardware problem concerning the not locking of GPS signals.

There is a small piece missing on the GPS side of the motherboard, see the difference on the two following pictures for comparison (broken on the left, correct one on the right).

To solve this problem, I soldered a small ball on the antenna side, located on the plastic frame:

After reassembling ... done!!!

The GPS is fixing again, very quickly with high level of satellites.
[Sony Xperia XZ1 Compact Questions & Answers] martin_sz:
@hubert-bangol where is the antenna exactly located - upper corner, lower corner, left, right ?
[Sony Xperia XZ1 Compact Questions & Answers] hubert-bangol:
Ho sorry I just see I posted on the wrong forum, it's not for XZ1 Compact, but for Z3 Compact. But the problem seems to be the same.

The location of the GPS Antenna is showed below:
[Sony Xperia XZ1 Compact Questions & Answers] Andrey_zZz:
Unfortunately, there is a hardware problem - main board looses contact to the gps antenna.

I found an easy fix - get small piece of paper (4-5 layers) or old credit/sim card and put it into the phone under the main board under sim card tray just where plastic EMEI/serial number tape. It should make pressure to the main board and bump it closer to the screen where the antenna contact is.
[Sony Xperia XZ1 Compact Questions & Answers] martin_sz:
thanks for posting this.

Did I get it right - this is the tray with the SIM and SD card and you put some paper below this tray?
[Sony Xperia XZ1 Compact Questions & Answers] Andrey_zZz:
That's correct. You can find imei tape inside. Just replace this tape with piece of plastic or paper.
[Sony Xperia XZ1 Compact Questions & Answers] martin_sz:
I cannot find this imei tape.

I just removed the tray.

Do I have to remove the display and disassemble the mainboard?
[Sony Xperia XZ1 Compact Questions & Answers] Andrey_zZz:
Are you sure you have XZ1 Compact? Please read user guide to find it.

If you are able to disassemble the display and mainboard - you will definitely be able to fix antenna contact (see previous posts). But this is quite hard and dangerous procedure.
[Sony Xperia XZ1 Compact Questions & Answers] martin_sz:
thanks a lot. I didn't know about this strip. Now I got what you meant from your original post. thank you
[Sony Xperia XZ1 Compact Questions & Answers] hockeymikey:
Yeah, this didn't help me in anyway.
[Sony Xperia XZ1 Compact Questions & Answers] KaarenKaks:
There are videos which show how to rub the backside of phone to get gps working again. And it works for some time. Apparently there is something glued or taped back there. It works for some time, not only the moment you apply pressure on the back. It shows there is something that sticks for a while and then loses contact again. What is frustrating, I can`t find any picture what/where is this exactly.
[Sony Xperia XZ1 Compact Questions & Answers] MilesBHuff:
I had this issue after flashing Havoc 4.X. Downgrading to the stock ROM had everything working perfectly. LineageOS 17 also has a functional GPS -- I recommend using that ROM instead of Havoc if the latter is not working for you.

I also cobbled together this `gps.conf` file, and it's been working fine for me in LOS: https://github.com/MilesBHuff/Android-GPS-Config/tree/xz1c_us
[Sony Xperia XZ1 Compact Questions & Answers] Hornelen:
Thanks a ton! This worked for me. Lineage 18 is what i run.
[Sony Xperia XZ1 Compact Questions & Answers] FlashDude:
I finally found a solution, for me it was a hardware problem. Found over 20 satellites but didn't fix one of them.

After carefully taking off the Display with a suction cup you just have to screw off the big metal shield held by many black screws and one blank one. In the middle of the mainboard you see a tiny spring box.

You have to use a USB-Microscope and a needle to slightly and gently pull it up so it touches the metal shield again.

I also bend up 2 other pins on the metal shield itself.

Then you slightly and gently bend the whole metal shield so especially the middle is pushed down on the spring pin once screwed back on. Make sure the blank screw goes where it was. Carefully assemble it all again.

And there ya go, satellites fixed in seconds.

A sight not seen in a long time.

[Sony Xperia XZ1 Compact Questions & Answers] Tommasodnm:
@FlashDude Thank you very much for sharing your solution! I woudn't repair this amazing phone without you.

I proceed exactly as your description and finally my XZ1 compact gets GPS fix :) It connects 12-17 satelites in the house near the window :)

I did not use double adhesive gasket, I glued screen by B-7000 transparent glue at the end.

So tomorrow I am gonna repair my wife's Huawei P9 - same issue, simplier repair i suppose (no glue)
[Sony Xperia XZ1 Compact Questions & Answers] hockeymikey:
Can confirm the hardware fix is the solution. You can test this by pushing down on the screen in the area that the pin would be located in, making that connection. I pulled the pin up and gps worked great on one of my models. Gonna experiment a little more but I'm liking the success so far.
[Sony Xperia XZ1 Compact Questions & Answers] antoniu200:
Just a heads-up, B-7000 is not going to keep that top speaker in place and, hence, will intermittently stop working. You might want to invest in something stronger if you want to daily drive the phone.

Even those cheap AliExpress adhesive strips, coupled with some 3M Primer 94, will hold down the top part of the screen much better: https://www.aliexpress.com/item/4000865228749.html &

@FlashDude

Thank you very much for sharing this solution! My XZ1 compact GPS is working again! :D
[Sony Xperia XZ1 Compact Questions & Answers] FlashDude:
It's great to hear that it helped you guys, I got that sealing rubber piece from ebay, availability depends on where you're located though I guess. I'm sure there's some kind of black rubber sealing paste that's still removable.
[Sony Xperia XZ1 Compact Questions & Answers] brodo:
Thank you so much! This actually worked. Although on my first try it didn't sustain for much long. Maybe it is related to a magnet that I was using in my car to keep the phone in place on the dashboard. I will see how it goes without magnet... (was planning on abandoning this solution anyway since it confuses the compass)

Would it be possible to make it a more permanent solution? Could I place, say, a small bit of tinfoil between the spring and the metal cover? Or would this be an horrific idea because of reasons?
