Short Review of a Sony Z5 Compact Prototype - Xperia Z5 Compact General

Hi guys,
I just want to share with you a short review I've made of a Z5 Compact Prototype. Since then I've installed Android Nougat and it works flawlessly (no low volume or any others bugs) other than it's still detected as a prototype so Send Usage Info is still ticked. Enjoy!
https://www.youtube.com/watch?v=MouJ9jtQfpU

Sorry for reviving an old thread, but have to ask:
Did you wipe old and flash a new firmware and still the "Send usage info" is there? Shouldn't that disappear when flashing with a new one?
I'm curious since I've been offered to buy a demo/retail phone.

No worries, mate; yes, the "Send usage info" remains ticked even after a new flashing. As far as I know there's no way of turning it off.

Thanks for the info!
Wonder if it has any to do with IMEI nr...
Since I usually avoid sending any usage info I think I'll pass on the phone I was offered.

I don't think it has anything to do with the IMEI. Overall, it's not like it affects you in any way. Only this option is greyed out and cannot be disabled; other than that, the device is completely normal.

Allright, maybe I'll consider buying the phone anyway if I get a good price

Help needed to buy a preowned Universal

Hi,
Could you guy's please help me out: I want to buy a preowned ("used" or "second hand") Universal.
If I was to have 10 minutes to test if the device is working without faults, what should I look after?
I figured that I should test:
- Reset: check the screen and any possible error messages
- See if strange effects appear on the screen, when rotating it
- Check the keyboard and other keys
- Check Bluetooth connectivity
- Check WLAN connectivity
- Check the phone with my SIM-card
Anything else worth checking?
I already have a Blue Angel and I like it so much (actually I depend on it, as I found out when I had to send it in two weeks for reapir), that I figured another phone as a backup would be nice - so why not move to the Universal for it's VGA-screen and faster processor.
My last question would be: is it really that much better? Or will it rather be annoying to have an even bigger phone, than the BA?
Thanks for your time and patience!
Best regards,
vma
That seems like a pretty good list. I'd probably want to add testing an SD card with it as well. The main thing I'd probably focus on would be the physical aspects of it because from a software point of view you can always hard reset the device and start fresh. (And honestly that's what I'd probably do first thing if I bought one second hand.)
I really can't speak to a comparison with the Blue Angel since I've only had the Universal. I've never had an issue with the size of the Uni as a phone, but I'm not a heavy phone user as far as talking goes (though I often have the data connection on.) Plus I have a bluetooth headset that I use most of the time for calls anyway.
hi mate i myself went from the xda 2s (same as you) to the universal. it is an amazing phone! i just cant fault it (obviously the size but when wearing a suit its alright because it can just go in your jacket.)
i am actully selling my xda exec. if you live near me i will be happy to let you play around with it before you buy. it is in great condition as it was a warrenty replacement device after the last one was playing up. havent used it for a while as i have an mda vario 2 now. since it is a better size for when you are down the pub..
ill probly sell the phone for around 240 or ono. comes with a spare battery as well
if you are interested my email is kerbys at gmail.com
most important from HW view is 2 check miniUSB connector, it loves to disconect from motherboard. if it will B possible try to connect it 2 computer, at least for few secs. if new HW appears in comp probable that its not dammaged, if U wonthave access 2 comp try 2 charge it (red led should be on)

If possible try to put one in bootloader mode and see the bootloader version. If it is 1 or below avoid. If you get ver 2.00 or above you can be assured of the latest hardware.

I agree. The G4 (which has the bootloader of 2 and above) also feels more solidly built and has a slightly better keyboard.
As well as the USB connector, also check that the phone accepts and recognises SD cards, check the infra red and check the screen carefully for scratches (you will need to hold it at different angles to a good light).

Not necessarilly true. My friend's G4 is now dead and a paper weight in just 4 month's, both bought brand new, as opposed to my 1 year and 4 month old G3. I still have bootloader version 1.00 and never had been stuck in any screen while upgrading. All the ROMs I flashed worked, and I've flashed my G3 a lot.
Hi guy's,
Thanks for you replies so far. To sum it up:
- Reset: check the screen and any possible error messages
- See if strange effects appear on the screen, when rotating it
- Check the keyboard and other keys
- Check Bluetooth connectivity
- Check WLAN connectivity
- Check the phone with my SIM-card
- Check the MiniUSB Connector with a PC (new device message should appear) and with a charger (red light should turn on)
- If possible: enter Boot-Menu and check Bootloader release. If >1 then it's a G4 model, which is newer, better, more robust
This could probably help as a general aide for other's as well.
Last questions:
1) Is a G3 model really that bad? What if I had one in mint condition in my hands? Should I NOT buy it?
2) Will entering in Bootloader-Mode cause a Hardreset afterwards? Would not be nice to wipe other people's memory off the phone and then NOT buying the phone...
@xda_kerby: I live in Portugal - sorry!

Yes, that is a good guide line.
To answer your questions:
- Having a G3 is not bad, as I stated from my above post. Think of it this way, if you want the latest computer chip, look for the G4, thus ensuring yourself of whatever reason they were replaced was fixed in your device. They all depend on how rough you use your device.
- No, entering a bootloader mode would not cause a hard reset. You might be referring to a setup screen where you either choose or press "0" if you want to hard reset or press "X" if you want to soft reset. They are different.
- Well, the seller should be responsible enough to know that it is his or her own duty to wipe it of by himself or herself before selling it. For what it's worth, he or she should be thanking you for doing it.
G4's perform much better with wm6 (I have both), so if you are thinking of upgrading to it then i would go for one
Sorry, if I am pushing my luck with another dumb question...
Suppose I wanted to buy one from eBay. I doubt that any seller would go through the trouble to tell me the Bootloader revision.
Is there a way to assume which Bootloader the device SHOULD have, from the purchase date, i.e. if purchased after MM.YYYY, it probably won't be Loader <v2?
Also, I have seen many sellers trying to sell a MDA PRO which has recently been replaced by T-Mobile. I imagine they had a broken one (i.e. G3 model, from what I understand) and it has been replaced by a new one (they don't write anything about refurbished). Would that be automatically one with Loader >v2?
Will the unlocking described in the Wiki work with G3 and G4?
Again, I thank you guy's for your time!
Cheers,
vma
In my experience with O2 UK, they recondition handset's and unless you ask specifically for a brand new handset, you'll receive a reconditioned G3 model.... I had a battle with them for a couple of months over this lol Broke them in the end Every handset they tried to give me as replacement was a G3.
Because of this, I think it may be hard to rely on purchase date being equivalent to model number from O2.
Thanks!
I will try my luck at eBay...

Fake S5 - will it work on original rom?

First of all, hello everyone since this is my first post and thread on this forum. And thanks for all the help I had found in the past. And sorry if my English would not be understandable sometimes
So I bought this fake Galaxy S5 in China (Silk Street in Beijing) - I did it on purpose, knowing from the beginning that I'm buying a fake. Didn't expect anything big from this phone, but after a few days of using it, I'm very surprised by its good quality. It has some chinese features though, and the rom is not fully translated into Polish - sometimes mixed English/Polish, but I don't mind. Ant the battery is certainly a poor quality fake, because it discharges in a few hours of normal using (or not using at all) - maybe something in the chinese rom is draining it? Definitely I will buy an original one.
And! The most intriguing thing is, that the device keeps changing its MAC address. I know it's hardly possible, but I checked it precisely - MAC changed at least 3 times after complete discharging or forced reboot.
I was worried about flashing some 'real' rom into it, not knowing if the hardware would handle it, but I ran the CPU-Z and this is what I got:
View attachment 2912728
View attachment 2912729
View attachment 2912730
Can I consider this phone as almost original S5? Only the CPU is somewhat different, but the RAM is the same as in the original, even the screen is FullHD, which surprised me the most. And if yes, is there any suitable custom (or original) rom for me? What should I even think of this phone? Only thing I know that I made a good deal - it was like $130
Thanks in advance for your help!
First, don't trust the results that you appear to have in hand. CPUZ is a fine utility but many fakes go out of their way to feed spurious information into the app. There are already a few hints in your results that they are spurious. Before you trust those results, vet them against several other apps e.g. Samsung Info and a full benchmark suite.
One important clue is whether you can enter a standard download mode. Pull the battery and then use the volume down + home + power sequence to see if you get a download mode and if has any irregularities.
As to your original question, almost certainly no. Trying to write an original firmware to your known fake is likely to brick it. Perhaps irretrievably. You need to identify who made the fake and search out the proper utility to write firmware to the device. if you do a search of this forum or my post history you'll find the name of a forum that specializes in fakes and likely can aid you.

Do you still have that phone?

ZenWatch Always-On screen option doesn't work

My newly purchased ZenWatch is set to have Always-On Screen but after 5 seconds it fades a little, then, shows the dimmed version for a second, then goes completely black so I can't see anything until I wake it again.
Wear version 5.0.1
Connecting to Android 4.4.4
This happens the same with any watch face I select: pre-installed or new custom ones. I have tried uninstalling Wear and ZenWatch Manager, resetting the watch and starting over again, same thing happens.
Could an app or watchface I have installed be interfering with the Always-On option somehow??
I don't know if this is related but I had to return my first watch as it didn't charge, so this is the second one connected to my phone (after 'forgetting' the first then pairing the new one).
When I click on the Always-On tick box on my phone, it immediately updates this option showing on the Watch so it's definitely sending the command to it. It shows as Always-On selected on the watch.
Has anyone else had this bug and know how to fix it? Thanks.
Is cinema mode on?

Thanks, no, cinema mode isn't on.
It's really curious, the screen fades slightly in brightness after five seconds, then goes to the dim version of the watch face, then goes completely black a second later. One tap brings it back so I'm it's like the regular off screen mode.

Hi,
I'm very curious to know if you have found a solution to this problem as my new ZenWatch is doing the exact same thing. Asus support has told me it's a firmware issue but that seem odd to me as the feature seems to work for others.

Oh thank you for telling me I'm not at least alone! No I haven't found a solution - I have reset the device, removed all the Wear apps one by one from the phone (in case a setting is interfering) and nothing makes it work as it should.
So... firmwear meaning the version of Wear that's installed on the watch? I was considering seeing what options are on the debug? menu but following online instructions I couldn't get this to work (you have to swipe from top left etc). I'm on 5.0.1 build LWX48S bought in the UK, how about you?
Have you had another watch that you replaced? I have and thought maybe settings got confused between watches. On my previous one, the always-on screen worked fine on it. When I booted it up for the first time, it did a software update. It however had a power problem (didn't charge after 2 days), so I replaced it.
The replacement didn't update when booted up, and doesn't update when I reset, so I assumed it shipped with newer firmwear - maybe the always-on problem is caused by this?
One weird problem with the replacement watch is that it notified me that it was almost out of power, despite having about 75% batter left, then it switched off and didn't turn on until charged over night. Only happened once.
I was planning on swapping it for another at the shop but someone else having the issue makes me think it's software. Might wait for an update, but if not solved long term then I'm not happy - I want it to look like a watch rather than a blank screen.

Just got my Zenwatch and I am having the same problem... Resetting the watch helped. But, I am still not getting the watch to vibrate on notifications. It vibrates when I set an alarm (on the watch) to it's not the vibrating device itself...

I have the same version of Wear with the same build number and I am also in the UK (which may be the common factor here as it is looking quite likely to be a manufacturing batch issue). When I first got the my watch from Heathrow terminal 2 it had an older version of Wear pre installed and the always on mode was not working then either. This would suggest the Wear version is not the issue here but the ASUS firmware which links Wear to the hardware is at fault.
I have also done the uninstall all apps from my Nexus 6 and factory reset the watch thing but ultimately it made no difference.
This the response I received from ASUS BTW,
Thank you for contacting ASUS. We are sorry to hear about this problem. I believe this is due to a firmware bug, it is not a setting that you can choose.
Please be advised that I will forward your feedback to our HQ development department to see if our engineers can resolve this problem in the next firmware update.
We are sorry for the inconvenience caused.
I also share your sentiment that a watch that doesn't tell the time is not much use to me so I will be rolling the dice and returning it for a replacement unit in the hope for a device that works as advertised.

Did you return it in the end?
After several frustrating emails with ASUS support in which they replied with general info on how the Always on-screen setting can be set, then asked me what build number I had even though I told them this in the first place, they concluded it must be a hardware problem.
"Taking in consideration that you have both the settings enabled on your watch as on your connected device and you are using the latest firmware, I also believe this is being cause by a hardware fault. Please return the ZenWatch back to your reseller."
So I took the plunge and exchanged it for the second time with suspicious staff at the shop (it was past their 21 day return policy cut-off, so I had to order another, then swap the new one for mine, on their system they refunded the new one). Hey presto, the new one works fine!
This one shipped with: 4.4w.2, KNX01W, updated to: 5.0.1, LWX48S.
So overall sounds like perhaps just a hardware issue. I know it's a new product but it's lucky I like the look of the watch so much that I'm tolerating quite a few teething problems. The one I have now has a very slight ridge on the right hand side of the screen where it meets the metal frame, which you can feel when swiping right. Hopefully I'm just being overly-fussy now and I won't notice after a while, but it's not as smooth as my previous two watches. On the left of the screen it's completely flush.

I went to take mine back last week only to be told by PC World that this product can only be bought on-line and I would have to buy another one and then return the first for a refund. Which is a bit of a scam to me as the replacement was at a higher price than the first one I bought from Heathrow Duty Free.
I am due to collect the replacement and have an argument about the price difference tomorrow so finger crossed I get a working one as well.

Ha, mine was from PC World too. I guess it's not their fault that your original one was bought duty free & therefore cheaper, but really if it's faulty they should treat it as such. They did offer me the option of booking it in as faulty, then it would have been sent off to ASUS and in all probability replaced with a new one anyways, but he didn't know how long this would take. So I just took the other option of buying another, having it delivered to the store the next day then swapping & refunding the latest transaction.

Well the good news is I now have the replacement watch and it works as advertised. I did have to complain a lot to get the difference in price resolved. I ended up complaining so much that the store manager gave me the money out of his own pocket just to get rid of me .

Few X Compact problems.

Hi, thanks in advance for reading this and possibly helping me out.
I've got few problems with my Xperia X Compact stock Oreo, probably new, but I bought it from other person, not a shop so I don't have any document for that.
After running it first time I had to upgrade it right from the bottom, Marshmallow, so mayby it was really new back then.
But lets get to the problems I have right now :
- When someones calling me and I have phone in my pocket, after pulling it out screen is maximally dim (had few phones, never with that super life hardening FEATURE..).
- - - - - phone only vibrates for like 2 seconds, at my loud work I often don't hear and feel phone ringing in my pocket.
- Accelerometer is absolutely not working, checked with inphone technical support program.
First two problems seem software ones or it's normal guys ?
Third is hardware one for sure, but without any document of purchase of the phone I'll have to give it to local phone service, right ? Sony will pee on me for sure.
I'm from country that suffered biggest defeat at this years World Cup.
34.4.a.2.70 thats the version i use, stable battery life and everything okey, try flashing this rom, and full reset
I have 34.4.A.2.50 and no new updates available, then almost same version like You and something's wrong.. I don't want to flash new ROMs except for Pie when it comes.
Edit. Rotation is surprisingly working again.. By doing nothing just creating new thread here.. Rest as it was..

Nexus 6P angler-userdebug 8.1.0 question

hello, my first post, I bought a Nexus 6P from ebay. It has an unlocked bootloader (I get the warning when I turn it on) and the os build number is "angler-userdebug 8.1.0 OPM3.171019.01445.3998 dev-keys". there are applications that are not uninstallable: Better Bug, Nexus Logger, Traceur, and Volta. My question is, is this device suitable for personal use the way it is? any other information and/or suggestions are appreciated.

I am not sure about the rom version.
https://developers.google.com/android/images#angler
It sounds like somebody sold you a former test model from Huawei.
I can obly assume, that they sold remaining units, but after I searched a bit about those applications I can, like I said, only give you a vague assumption.
The important questions are -
Is the phone functional?Meaning: bootloop, sudden reboots, battery problems?
Are you able to use adb/fastboot? - > Is your phone being recognized by the command 'fastboot devices'?
Did you get a notification that is your system can be updated?
The unlocking of a bootloader isn't a reason to be distinctively suspicious?
But, if you are not satisfied with the phone in whatever way, you can demand to be refunded in regard of the unlocked bootloader with the argument, that the seller has tampered with it and should wrote it in the description.
I bought a phone a while ago and were unsatisfied with it, so I argued with the above mentioned and got my money back.
This was even from somebody private and there are no refund policies, besides the buyer protection.
If you have not passed thr chance and don't want to have a phone, which somebody has used most likely to flash a custom rom or recovery to root same phone, then go for it.
It is not a 100% bulletproof argument, but ebay excepted it, at leat in my case.
If you are okay with the device and adb/fastboot are working, in a way that you for example can test some commands, whicj you have to look up, but __don't flash anything__ as long as you are unsure of the condition.
If you want to remove these apps, you have to look them up, which is expandable and which isn't, before removing them.
And lastly - if you want to remove them, you have to root your phone (tutorials find you here en mass, the same goes for adb/fastboot usage).
But the same goes here for testing a ADB and fastboot usability, please.
If you decide to keep it, then you can remove system apps (>before a search if you phone goes boom..), aith this app for example
https://www.apkmirror.com/apk/jumobile/system-app-remover-root/system-app-remover-root-7-1-release/
With this, you are able to backup the apps if you want to remove them.
Some apps, especially the so-called 'bloatware' is from now on then, quite resistant.Just empty the trash, which you find in the app's menu.
Titanium Backup, a very, very versatile application, is fir example capable of backing up your entire apps including data, but I think, you have "some" pointers now and can give it (with carefulness) your own try.
Have fun & good luck
