Hi everyvone!

I've flashed on our device twrp and a cwm but I can't get into recovery by hardware buttons anymore. With the stock recovery it was posiblle, I can go into twrp only with mobileuncle. I'm on stock rom and have not change anything else beside recovery because it was on chinese. Does anyvone has that issue?

This is a very simple director antenna that you might try. I'll post yet another photo of a single strip of aluminum foil mounted on the side of the phone, it works for me but i have replaced the inner antenna so i might not work for you.

Hi,

as for the first link, I already answered that in #793. Read it, and if you still have questions I´ll be happy to answer - if I can.

As for an external GPS antenna - well, it looks a bit clumsy, don´t you think? If you want to use some external stuff then a Bluetooth GPS receiver would be to prefer. You can find on eBay for 30-40 US$.

My solution, also refined by tommi.r and some others here has the disadvantage that the foil must go away from the phone. Unfortunately this can not be helped. I also tried to put it on the cover, inside, outside, in every possible directions, shapes and forms - but I failed. I´m affraid that this phone does not fit for the workout tracking. I used Cardiotrainer and Endomondo - but got crazy results. Sometimes I ran at a speed of 295 km/h. I´m quick, but not THAT quick...:)

Of course you can try with foil proposed by tommi.r . I´m sorry not being able to help better.

One question, why everybody need to root zopo zp998???

It is rooted from beginning, always

When i buy my phone i always have option; SETTINGS/SECURITY/SUPERUSER on this phone, turn on and superuser is works, in stock rom..

options was everytime, always after every OTA upgrade,
[Upgrading, Modifying and Unlocking] jjkraak:
It has been mentioned a few times. It is not a full root; lots of stuff you will not be able to do.
[Upgrading, Modifying and Unlocking] dromaczek:

[Upgrading, Modifying and Unlocking] dromaczek:
Then i dont know what meat "partial rooted", everything works -> titanium backup, mobileuncle for install cwr, cpu vendor, editing build.prop for dpi.. etc

maybe other users dont know that this phone is rooted:) or like to be rooted twice cause rooted once is worst that rooted twice... twice is better...

GPS - improvement by foil works well but potential SW bug seem to exist

Hi, guys.

I read this thread some days and have made some tests with foil strips to improve GPS signal level on my ZP998 - thanks to lasslax and tommie.r the signal is really better now.

But on this phone there is one phenomenon, that doesn't exist on my older phone GSMART 1310 :

When i run Sygic navigation - Settings - Hardware setting - GPS sattelits, I can see "radar beam" rotating and some sattelits in a circle.

On the side is graph with signal strength of particular sattelits.

Every 5-10 seconds all sattelits are cleared of and after 1 second appearing again. The time interval is not regular and may be longer.

On my old phone GSMART 1310 are sattelits stable all the time !?

On my colleagues phoene Samsung are stable too.

Isn't this some SW problem on ZP998 ?

What do you mean ?

In "GPS test" app this drop-outs don't apperar...
[Upgrading, Modifying and Unlocking] lordofdarkness:
The GPS problem is an hardware problem. But the problem is the antenna GPS, in fact GPS chip is right.

Inviato dal mio ZP998 utilizzando Tapatalk
[Upgrading, Modifying and Unlocking] jjkraak:
Hm I'm pretty sure I tried it back in March/April and when I used a rootchecker it returned false. If you search for root on this thread, the third post you'll find also says root does not work. Maybe it was fixed with a newer firmware? Or could it be that not all roms were able to include the superuser setting? There must be some kind of explanation other than people just not knowing about it. For example, this page existed for a reason.

Edit: A yes, I believe it was fixed with the 03/29 update! Mystery solved:)
[Upgrading, Modifying and Unlocking] dromaczek:
hmm, strange, i upgrade 28/3 and work on it, before it - works too (after switch on root on settings/security).. rootchecker check ok - always..
[Upgrading, Modifying and Unlocking] jjkraak:
See my edit:)
[Upgrading, Modifying and Unlocking] dromaczek:
hmm yes solved.... maybe my memory is bad., mystery solved:)
[Upgrading, Modifying and Unlocking] vockor:
I mean antenna is a piece of metal - it cannot produce 1 second signal drop-outs in itself, when it is on the same place all the time and signal is strong enough... Drop-outs must by produced by some process - in SW or in the chip, or mustn't ?
[Upgrading, Modifying and Unlocking] lasslax:
Well, it is of course possible that we also face some SW problems with the GPS. But since the improvement of the signal also fixes the navigation problems, if there are any SW errors, they don´t seem to influence the usage. I don´t know exactly how Sygic works, I only guess it from its behavior.

The basics:

The navigation apps like Sygic or Waze don´t directly talk to the GPS chip. The system reads the GPS chip and calculates the position.

Don´t know it´s regularity. The navigation apps ask the system by an API, and use the answer they get. Don´t know how often they ask. Don´t know if the answer they get is syncronized with the refreshment of the location calculation. There can be some slip there.

But I believe that Sygic is smart enough, that if it gets a position from the system which is out of the bounderies of expected positions, then in omits it and asks again. That way it is not as jumpy as Waze, which uses the immediate response from the GPS, whtihout critics.

Now the Internet is full with complaints about the GPS chip used by MTK Soc. Basicly every device with MTK platform has problems with the GPS accuracy. When I bought my Zopo 998 I hoped that MTK fixed it at last, because I read it in some recensions. Unfortunately it´s no better, and combined with the malconstructed antenna - the result is catastrophic.

I may be wrong, but I don´t think so :)

I sold my 998 now and got a Note 3 - boys, what a difference!

---------- Post added at 04:59 PM ---------- Previous post was at 04:55 PM ----------

Yes it can. If the signal drops below a threshold, then it might produce an "out of bounderies" or any other no interpretable result.

Hello all,

about other problems this may have ...

I wanted to share a strange issue that I have from the beginning with my Zopo ZP998. In fact, I had to take my ZP980 because of it. I use 2 SIM cards constantly with my Zopo. It happens from time to time after a few hours or a few days that the radio signal is going nut. The phone seems to get signal, I have full bars, and I do have 3G connection. However, if I try to make a call, it's getting stuck on "making call" during a moment, then bars begins to fall slowly, and at the end says "network unavailable". I can try again as much as I want but nothing to do, it does not make the call. The only way to solve that is either:

- Not to be under cover of a 3G antenna, but only Edge, then it works again

- Disable manually 3G in the settings

- Deactivate and reactivate both SIM cards

- Reboot completely.

And this happens on both SIM cards, because when I'm in France and I turn 3G on Orange SIM card, I get the same thing after a while. This is really annoying because I miss calls that are notified me if by some miracle I lose 3G and it reconnects in Edge.

I wonder if this is a software or hardware problem, because I tried to reflash several times, and also tried a lot of ROM (recently Kitkat), and suddenly I have tried many version as modem (January, March, April and June recently).

I've also tried to disable certain frequencies, without success.

I wonder if it is not being whenever roaming on one of the 2 chips that does this, but I really can not isolate the root cause of this trouble.

If someone have an idea, i would be glad to read it :)

Thank you in advance.

the issues with this phone do not seem to stop.

the gyroscope was fixed in the recent update and apps like Google Sky Map seem to work ok now.

unfortunately the battery drain reached extreme levels since the last update. last night I charged my phone up to 100%. wifi and data usage are disabled. there are no running apps. less than 5 hours after that the phone is at 90% without even the screen being turned on for a second. while I was looking around to determine what seems to be the issue, the battery charge dropped to 80% for less than 5 minutes. keep in mind that the screen's brightness is set to minimum.

did anyone else notice this, since the last update was released? it does not seem normal for the phone to drain the battery times faster than before, especially when all connections are disabled.
