[Q] Touch Screen "error" - Galaxy Tab 4 Q&A, Help & Troubleshooting

I only put error because I don't really know what else to call it. Whenever I use my tablet and I play a game that required me to hold a button down for a period of time, it lets me hold it but then just stops responding to touch until I lift my finger up and place it back down again. Does anyone know why this is happening and if there's something I can do to fix it? If it helps, I'm using the 7 inch version and although I'm running a custom ROM, I've had this problem ever since I got it.

Hey, I just bought this tablet to test my game and I have the same issue. It happens to me with games like "league of evil". I'm touching the move buttons while touching jump or punch and the move buttons stops responding until I lift my finger and press again.
Also I've setted debugging options to see touch presses and the touch is not registering.
Any hint on why this happens or how to solve it?

Hi sorry for my bad english im from México and only speak spanish. I have the same problem , i think is a touchscreen problem.my cuestión is: if a got root and calibrate with an app that can solve my problem? Is a regular problem in this tablet? I have sm t230 wi-fi model ,no root and stock 4.4.2.
Enviado desde mi MotoG3 mediante Tapatalk

I think this problem affects all smt230 but still don't know if it can be fixed. Maybe with the next os update?
Español:
Creo que este problema le afecta a todas las smt230 pero todavía no se si tiene arreglo. Capaz en la próxima actualización del sistema?

Never happend to me in games like modern combat 3,4,5 and order & chaos online, been holding move stick for 15 mins in row and never got timeout for touch. It must be because of app not the tablet, if its tablet try installing other ROM or factory reset.

Hi thelous, I'm interested in what you've responded. You have smt230 wifi only model with stock firmware? I'm downloading order & chaos online to test it.

[Q] Defy only emergency calls--------------Help

Hi,
I had to use macgyver battery hack to bring my defy to live.
Everything is working except defy only switches on in emergency calls mode.
There is no service from carrier.
Tried base band switch app
MFUNZ_DEFY.BasebandSwitcherV4.1.apk
but it says
unable to detect your baseband configuration, it's possibly damaged. reset to default?
Tried rename system/etc/motorola/bp_nvm_default and even move the folder.
But reset to default is not possible.
I have tried eclair (full SBF), blurlessginger & some other fixed froyos, cm 7.1 & cm 7.2.
Without any success.
Can anyone suggest a way forward or the phone is to be discarded.
Regards
Are you using baseband 4.0?..uhmm maybe your cellphone have negative band

If you are asking about the version that is on your (new) phone. Go to settings / more / about device
You will also see your model number. Just filter your model number and you can download the appropriate official firmware.

Lenovo Z6 Pro L78051 4g connection problems

Hi.
Sorry for my bad English, it's not my native language.
Ask for their help to know more about the 3G and 4G connection bands.
Buy a lenovo z6 pro, the 8gb / 128gb version, bring the bands B1, B3, B5 and B7. In my country (Mexico) the operators use the B2 and B4, but in some regions they are testing the B7. I decided to buy it because where I live my Xiaomi connects to the B7 but now that I have the Lenovo it seems as if it could only connect to the 3G. An operator (At & t) also uses the B5 for 4G but does not connect to it, only 3G.
There have also been many problems with the roms of the Lenovo team since they sell a version as global but it is not, it is only a hybrid version with deleted Chinese applications. Therefore it follows that there is no global version. I don't know if these problems have to do with connections.
Annex two images where I show the Xiaomi that connects to the B7 and what an application of the Lenovo tells me.

My phone is with CN 11.0.575 and parched with the ZaZz version (The .bat 00_flashrom.bat anywhere), i already have TWRP Recovery and now is rooted with Magisk. I CAN HELP WITH AL THE PROBLEMS OF YOUR SOFTWARE, But, now i want to install the ROW Secure 11.0.284 version, i cant, i dont know if is the version of my QFIL, the drivers, but the process just arribe to system_3.img and stay every time that ypu want. I dont know, but i want to try with that ROM. I just can with the CN 11.0.575 ROM, i areally want to try with ROW, im using QFIL 2.0.1.9 .
Hello
I have very similar problem in fact the same I believe
When I start or recieve a call my current 4G full signal strength connection drops immediately 3G and the signal strenght become very poor. On the other hand while surfing on the internet there is no quality drop.
I have run a diagnistic test to my sim card and I get an error. I hope you have any information about it.
I am currently using 11.0.325 ST Global ROW. But on official stock rom the situation was the same.
It seem you have the Volte option not activated.
Check in your setting or maybe not activated by your operator ( turkcell by your mcc)
But i cant read turkey , i let you check that.
It's not a band issu, because you have 4g before call.

I think that is not a problem. In the Xiaomi I had before that happened. had 4G when answering calls changed to 3g and at the end returned to 4g.

have you tried with Chinese ROMs? or with this menu * # * # 4636 # * # * on dial. It gives you to choose the connection priority and some of the calls.

I've got the same problem in Russia. If the 4g is strong enough, then, the incoming call is OK. If the 4g signal is poor, or there is 3G or 2G signal, then when I answer phone the other side does not hear me, because my phone's microphone doesn't work. The problem is in the proximity sensor. To solve the problem you need to use to install Truephone app, and switch off the pre-installed google phone. Truephone does not switch off the screen. Another solution is to install 575 CN firmware.
Hi. Do you have the VoLTE function active? You can see it with the menu on call (*#*#4636#*#*). What ROM are they using?
I am from Mexico and in the network provider I am only receiving H+ (It is 3G but faster). My problem is about the bands. Because if my previous cell phone connected to the
Band 7 in 4G, this does not.
And I haven't had the problems they mention. If I have little signal, the call fails me; but if I am with 3 or more signal intent stripes, it works perfectly. I have the ROM 11.0.325 ST

Try to use Signal Network Guru app. There is an option to activate\deactuvate the bands manually.

Hello everyone.
I bought a chip that uses band 2 for 4G and I bring 2 chips. Since I have one of them when it warms up, an x ​​begins to appear in the signal and does not recover until I get into airplane mode or restart it. But the strangest thing is that when I play and the cell warms up, they both start to fail, as well as Wi-Fi, they turn off and turn on, until it appears to me in the bar as if I didn't have a SIM and the Wi-Fi also turns off. when I had a chip that never happened to me.
Do you have any idea why it is? And why when the cell phone heats up does that happen or will it be the other SIM Does anyone else happen to this?

I applied your solution it helped thank you. But it is not fully solved. I tried all roms ( official, Zaza version, global version) but the problem always exist. Can we fix this sensor or the problem is about the antenna?

Yes, we (4PDA Russian community) are close to solve it. We found that the problem is in EFS partition. That partition contains the info about all kinds of phone's networks and IMEI also, and we have an opinion that only 575 CN firmware is totally ok for the sensors and antennas. So it is a great idea, but it has not been tested yet. For the first you need to install 575 CN via QFIL, 2nd - to install TWRP, 3rd - to backup the EFS partition via TWRP. To save that backup on SD-card. Then install the global firmware (the latest 375, for example)? TWRP again to restore the EFS from backup. It has not been tested yet.

Everything working fine with me.
