[Upgrading, Modifying and Unlocking] Retseem:
Bought this phone 3 weeks ago when i was in China.

First thing noticed was the ghost typing, updated to the latest version of 02-18 and the problem seemed to be solved.

Though after intensive use the problem came back, the whole screen got mad at use, not only when using the keyboard. Laying the phone to rest for awhile and rebooting it solved the problem for the time being.

2nd thing was the GPS wouldn't lock, tried all software and ROM tricks available on XDA but ended up in unscrewing the back of the phone, tighten the connections and properly putting it back together again. Now I had GPS fix within seconds and GPS was accurate.

3rd issue I have that I can't pair bluetooth since I can't enter a PIN and it continuously pops up that I entered a wrong PIN. It does this when paring to my car's bluetooth as well as with my bluetooth speakers. Didn't solve this one yet and probably never will.

Last weekend my phone went completely mad, as if someone was touching all over the screen starting apps and opening screens randomly. Like a ghost was playing with my phone. At one time it even dialed 112, the emergency number and I had to take out the battery since I couldn't control the phone anymore.

After the phone booted up again the touch part of the screen was completely dead including the capacitive buttons below the screen, so I was unable to use the phone at all. After a few battery removals an boots I got half the control back, the capacitive buttons and the lower half of the screen. So lower half of the screen reacts to touches, the upper half doesn't, so if I need to touch a button which is on the upper part of the screen I need to rotate the screen first so I can use it. Also booting in recovery mode is not working anymore (Phone is rooted and has CWM recovery)

After these experiences and having read all the sh*t many other people had with this phone I'm completely fed up with this phone which is now unusable.

Now looking to get a new phone, but can't decide yet. MlaiS MX69 Pro (quad band WCDMA) or the Iocean X7S elite.

[MENTION=4780715]Retseem[/MENTION], heads up. The phone isn't as bad as you think. It's just a phone which has a slightly buggy software.

Time to reset your phone (including the memory) and restart your optimization project. Restart your phone in factoy mode (Volume down and then power, keep both pressed until the screen comes alive). Shortly after releasing the buttons you'll see a Chinese menu. Scroll down to the line containing eMMC and press power again. Your phone memory will be reset. Now restart your phone and check which software is on. If it is too old (not including the last screen fix #36 - I suppose so because your screen went mad) you should flash a new one (from Zopo or from needrom).

Hope that helps. Don't be angry with Zopo. They do their best - unfortunately sometimes this is not enough...

[MENTION=5440214]dragsterman[/MENTION], did you try MobileVOIP from play store?

If you have a problem with the mic please try "SpeakerBoost" by Omega Centauri. This improves speaker AND mic. Start with setting 30%. Worked for me.
[Upgrading, Modifying and Unlocking] dragsterman:
MobileVOIP also bad

I have tried MobileVOIP and the result is the same: my voice was distorted at the other side.

I have no problem with the volume of the mic, but I think maybe these SIP cliens can not properly handle the mic system of this phone.

Do you use MobileVOIP and is it working for you?

If so please share with me your settings and which ROM do you use.

Thanks
[Upgrading, Modifying and Unlocking] AP756:
I think I did try it once, but then I got carried away with all those other settings and with preparing my ZP998 starter pack. So no real help right now.

Three suggestions though: In MobileUncleTools (or in MTK engineering) choose MTK settings, goto hardware testing, Audio, Normal mode, SIP. You may try different levels. Download "PimpMyROM" from Play Store, start it, tweaks, telephony, AMR wide band (probably is already selected, if not switch it on). Download VIPER4Android FX, install it and modify your sound settings.

If you got a solution please let us know, maybe I can implement your settings and findings into the next issue of my ZP998 starter pack...
[Upgrading, Modifying and Unlocking] Retseem:
Unfortunately that didn't change anything.

I'm already on the latest stock ROM dated 2014-02-18, so the ghost typing issue should be solved.

I'm afraid it is a hardware problem, it's the just the top half of the touch screen not reacting to touches and sometimes the phone is acting like it's controlled by a ghost. So probably some bad connections inside the phone.

And about the MIC pr0blem, had that one as well. Normal phone calls on speaker worked flawless, but using Skype or any other VOIP service resulted in me almost unable to be heard for the person on the other side.

[MENTION=221567]fmotta[/MENTION]

why don't you download the stock rom from zopo?

You can flash with flashtool

and for import your imei use for example droid tools.
[Upgrading, Modifying and Unlocking] fmotta:
Already done, thanks.

But I was looking for a permanent solution.

Also, after reflashing stock, it seems not to be able to fix GPS anymore even after several AGPS restart.

I think I messed up something in nvram also for GPS hardware. My fault, in any case!
[Upgrading, Modifying and Unlocking] Mawe79:
[MENTION=221567]fmotta[/MENTION]

i think the actual stock firmware from zopo is corrupt. I have the same problem!

I actual don't think it depends on the nvram!

like i have written before. FW from January GPS works (but not fine), Stock FW (from Download Section; February) GPS doesn't work at all.

Tried to fix for several HOURS.......not even ONE Sattelite!

And i don'T think that there are informations in the nvram about gps but i'm not sure at all, but maybe some expert can hep us both out :)

If there is anything i can do for you....just ask.
[Upgrading, Modifying and Unlocking] Retseem:
Gave it another few tries to try to fix the touchpad part of the screen.

Found a firmware update for it on the Zopomobile Forum, but since the upper half of the touchpad isn't working and you have to disable autorotate so it was a hell of a job to install the new firmware. At the end I managed to do it by installing Droid VNC server and controlling the phone from my laptop. Unfortunately this update (touchpad firmware v33 to v36) didn't fix my problem.

Also tried all type of resets and wipes of the phone, all without any improvement.

Also flashing a new ROM (fluffy's ROM from Needrom) didn't solve it.

I don't expect any support on this one from Zopo anymore since I didn't buy this phone through their webshop but in a store in when I was in China. I have also taken the phone apart trying to fix it by rebuilding it and reconnecting all the connectors inside, so my warranty sticker is gone as well.

I like the specs of the phone, the looks and the screen, but the phone doesn't work like it should and support from Zopo completely sucks.

For me no Zopo anymore and I would advice anybody NOT to buy one until Zopo fixed everything, but I think they will sooner launch a new phone rather than supplying a decent fix, support and reliable firmware.

I ordered myself a new THL T100s Ironman and hope this one will do better.

The CNY 1800 spend for the Zopo was better used when wiped my a** with it and flushed it through the toilet.

Will someone confirm my experience with the GPS:

If I remeove the back cover (and thereby the NFC antenna), the SNR gets 10-15% better!

Ghosting

Hi all!

I was really excited by the phone when it arrived last Tuesday, and still am, when it is working. I'm having a lot of ghosting problems and often the phone doesn't respond at all. I was hoping that it could be fixed by the touchpad update, but seeing the post of Retseem I don't think I will risk it taking into account warranty issues. I ordered my phone through zopomobileshop.com and they replyed that I can return the phone to them to get a refund or get a replacement. I think this will be the best option for me, but am not really sure if I should get a new one. It seems that Retseem is the only one with this ghosting problem or are other experiencing similar issues? Also, does anybody know what the normal return policy is with regard to shipping costs? I paid about $50 for shipment from the European warehouse to Holland and don't wanna bother paying that again twice. Lastly, if anybody has any advice about stuff that I should definitely document, so that maybe PayPal can back me up when stuff goes wrong, it would be greatly appreciated!

Thanks!
[Upgrading, Modifying and Unlocking] Cifu:
My experience is differ from this. The back cover remove do not change the GPS efficiency at all. Note, the SNR (in YGPS) is hectic in my case at best, 10-15% in my case means only ~2 db, because my average SNR numbers is around 15-22 decibel. But i do not experience such high change from back cover removing.

I disassembled my phone, and try to check the physical contact of the Wifi/GPS antenna and the mainboard, but no luck, the difference is still marginal, and actually the Wifi signal is strong and stable. So seems to be not the antenna is the root of our problems, but either software related and/or a flawed design.

I not say such thing. I say it's gonna be nice, if the ZP998 has 32GB eMMC for this price. But it won't had...
[Upgrading, Modifying and Unlocking] giuliaspider:
I bought 4 Zopo 998 and they all work fine.
[Upgrading, Modifying and Unlocking] gordito_gr:
My friend just got this phone and he has issues with the proximity sensor.

Its not working at all. Screen stays on during calls and no gestures.

I removed the protector, factory reset the phone, also i installed a different rom. No luck.

All the sensor detector apps are showing errors or do not recognise the sensor.

Anyone else faced it? Any suggestions?
[Upgrading, Modifying and Unlocking] Cifu:
Please give us a clear statement, what means "fine" for you.

Many of us had very serious problem, like the GPS signal only provided more than 60 seconds in full restart (mine do about 90-140 seconds), and even if the YGPS show 5 meters accuracy, in the navigation software's (like the Google own 'navigation', or Sygic, or iGO, etc.) the reality is more like 100 meters, and the phone drop the GPS signal easily, so actually the ZP998 is useless as a car navigation.

You can check my experience in the pictures below:
[Upgrading, Modifying and Unlocking] Cifu:
Seems to be a Hardware failure, bad luck, need to send back for guarantee...
[Upgrading, Modifying and Unlocking] lasslax:
Well, I did some experiments, and for that reason I fixed a place there I could always put back the phone to the same spot. And when I by mistake placed it back without the back cover, I saw 10-15% higher SNR values, more satellites in site and more in use as well. I used GPS Test to check the values.

I begun to suspect the NFC antenna to interfere with the GPS antenna. I put a bit of tape over the contacts, cover back - no change.

Then I covered the leads from the NFC antenna contacts to the antenna with a piece of aluminium foil. Bingo!

Now I drove about 100 km and Waze freaked out only once for a few seconds, the positioning was accurate for the rest of the time.

So I wonder now, am I just lucky, does this only help me, or if I stumbled over something that could be developed to the better?

OK, I have Marsapa V5 installed. GPS test app shows 4 satellite fix in my office (1 meter from window) after 10 seconds. Navigation with Navigon accurate and GPS signal stable. NO problem with car navigation.
[Upgrading, Modifying and Unlocking] Cifu:
Ok, then perhaps ZOPO have different series of the phone (different hardware, or different level of craftmanship), just the heck know what this means. Several people report good GPS experience (like 2 owner in the Hungarian ZP998 topic @PH!, or Fluffy in needrom), but many users (sorrowfully i belong here) have bad experience with GPS, no matter what they do...

Lucky for you, not too lucky for us... :rolleyes:
[Upgrading, Modifying and Unlocking] lasslax:
The GPS problem is mainly hardware/construction problem. The GPS antenna malplaced, the signal/noise ratio is very low. I can definitely claim this, since I actually managed to connect an additional antenna, and also by shielding the leads to the NFC I achieved 40-42 dB, locked to 9 satellites. Without this I hardly get over 20.

Also the compass is a fail, navigating software using the compass fails by definition.

Navigon is a very professional navigating software that predicts your route (it can "show" your position in a tunnel by calculating your initial speed and position). This means that it does not jump suddenly off the highway to show your position 100 meters out on the medow, but it tries to cut off such anomalies.

Your phone is just as bad as ours, independently from the ROM you use.

Having said that, the firmware could optimize the sensor reading better, if the developers made some effort to it. That is our hope that Zopo will give it a try.
[Upgrading, Modifying and Unlocking] giuliaspider:
I compare the 998 with a C2, 980 and 980+. They all have same GPS satellite in view and strength. I cannot see any difference between these phones. I use a professional navigation software, because I don't want to stay connected always with the internet (local maps). I cannot say ZOPO is worse than others. Colleagues with Samsung S3 and S4 say they also unhappy with the GPS signal strength and navigation. But in the end for me is important I can use the phone without problems and this is the case.
[Upgrading, Modifying and Unlocking] warezjunk:
After using (2 days) an external BT tomtom GPS receiver, i enabled my internal GPS and used it with Sygic and NOT one problem on a 60 km route !!!

How is this possible??

Maybe the tomtom did initial things..

Before the tomtom, GPS was totally unusable.
[Upgrading, Modifying and Unlocking] Mawe79:
i compared them too. C2/ZP980 gets fix much faster, much more stable and much better signal as the ZP998.

The ZP998 has the badest GPS from all Zopos i ever test.
[Upgrading, Modifying and Unlocking] lasslax:
I have a C2 also. It's GPS is not good at all, but somewhat better then ZP998. I don't know 980, but 998 has definitively a problem with the antenna AND the compass. Navigation programs as Waze do use both GPS and the compass. Waze has the advantage of info on the current situation in the traffic.

I had an S3 - the GPS was outstanding. Probably because that also uses Glonass.

I made a mod to the antenna on the ZP998, got good signal, over 40-42 but I have a problem with its physical implementation. Still did not find the solution to it.
[Upgrading, Modifying and Unlocking] nima.kh:
hello guys i'v got the zopo zp998 recently and i was thinking of rooting it and flash a custom rom on it but since im new to these stuff i was hoping you can guide this humble noob here !!

thanks in advance
[Upgrading, Modifying and Unlocking] Cifu:
I do my best to recreate your experience, but honestly, no luck on my side. With the alufoil placed the cover back, the SNR numbers dropped below 20db, while without it, several sat's even get 25db. Maybe my foil is to much cover? I try to turn on and off the NFC, even covered the NFC connectors with duct tape to severe the contacts, but all-in-all, the YGPS show better numbers without any foil. :rolleyes:
[Upgrading, Modifying and Unlocking] Cifu:
Check the OP post in the first page of the topic. You can root the phone with Framaroot, at first step, currently i do not recommend any further steps. The custom ROM's do nothing significant in my perception, just give a pre-rooted phone (which is easily can be done by Framaroot), and put up or down several apps.

If you still planed to bring custom ROM to your phone, check the net for help understanding how the flashing can be done with Flash Tools, but again i need to point out, you got help in the first page. You can find custom ROMs in NeedROM.
[Upgrading, Modifying and Unlocking] thebighunt:
Hi

is your phone connected to the USB wire?

I've dome touch issue when mine is connected.

I just need to unplug it.

TBH
[Upgrading, Modifying and Unlocking] lasslax:
The foil you apply is way too much! The piont is to shield the leads to the NFC antenna as they cross the GPS antenna. As you did, you shield off the GPS antenna from reception, no wonder your signal drops...:)

I found that I can create a director to the GPS antenna that increases the signal a bit over 40 for 3-4 satellites simultaneously. The problem is, that this piece of alufoil is attached to the phones back at one point, but it has to point away from the phone with about 30 degrees. I hope that I can find a shape that allows to be attached it all the way. Unfortunately no calculation can give me that, only experimenting.

You can recreate mine if you want and experiment on your own to find a better implementation.

Just for you:

Vágj egy 7 cm hosszú, 3 mm széles alufólia csíkot. Ragaszd kb 10 mm hosszan a telefon hátára a hangerö gomb fölött ott ahol elkezd görbülni a hátlap. A fóliacsíkot húzd el a telefontól kb 20 fokra, hogy a másik vége 3-4 centire álljon a telefontól.

Olvasd le az SNR értékeket - le fogsz esni a székröl.
[Upgrading, Modifying and Unlocking] carabaothai:
It is very strange. I used Pfuffy ROM 1.05 no problems with GPS

Then i used 1.07, 1.08.1 then a lot of problems.

I flashed Masarpa Rom v5 and miracle GPS very good (with Sygic too). FIx in some seconds and always the arrow on my road the first day, the second day.

But the third day, the GPS was crazy again and the fix very very slow to get !!!

If it is an hardware problem why ok 2 days ??? and now bad again ?

I no understand
[Upgrading, Modifying and Unlocking] lasslax:
Because your reception varies by the time of the day,also depending on the meteoroligical conditions, dry tarmark or wet, clouds etc. Since we are balancing on the edge of working - not working, sometimes it might be OK, just for go to hell a few hours later.
[Upgrading, Modifying and Unlocking] carabaothai:
Ok i know this

But if it was a hardware problem why it could be very good sometimes ?

If hardware problem it never could be good like i had, no ??? :p
[Upgrading, Modifying and Unlocking] lasslax:
I am sorry not being able to give you an answer that would make you happy.

There is nothing like godd/bad working in this case, only either it does or it doesn´t. Now if it changes while you drive, the result, depending on your navigation software will show you correct or rubbish. Nothing inbetween.
[Upgrading, Modifying and Unlocking] carabaothai:
The real problem that we read in every forum in every language is that 90% ? 98% ? of Zopo ZP998 have big GPS problems
