I have both mi Max and mi Max 2 and I live in an area where network reception is comparatively low.In my max there shows 2 bar of network signal but mi Max 2 shows only 1 bar and disconnects very often from network(4g).Is there any mod to increase signal strength ? Should I ask to replace the device from manufacturer( perhaps may be some manufacturing defect in the unit I received)? someone else has faced this problem?
Different SOC, different radios, different position of antena, etc... Nothing's wrong with your device. The only mod which could increase singal strength would be a hardware MOD, which i don't thinks is posibble really. You just need to live with it.
Thanks a lot for quick reply.now I will bear with it .
i have same problem you are not imagining it, the signal reception is a good 30% less than mi max

I picked up a second K3 Note with a cracked screen for peanuts on Ebay so I could experiment different roms and eventually for my wife.
But the wifi performance is nowhere near as good as my original K3 Note. It works fine near the router, but is all but unusable in the bedroom at the other end of the apartment.
I compared the ratings with Network Tools
On my main phone, the signal level is down to -71 dBm @ 39 MBs while the second phone goes all the way down to -127 dBm @ 35 MBs and frequently cuts out. In fact, pages take ages to download when surfing and the speed displayed on the flux indicator is in bytes/s rather thank kB/s or mb/s, and it is impossible to do any streaming.
In the sitting room, where the router is situated, my main phone reads - 52 dBm @ 135 MBs while the second phone reads -44 dBm @ 65 MBs and is perfectly usable.
I'm wondering whether it might be something like a damaged wifi antenna. I was planning to get a replacement screen on Aliexpress. But before doing that I'd like any pointers or other thoughts on this problem. What could cause this type of behaviour?
Thanks.
I've upgraded to stock Android 10 ( QKQ1.190910.002 V11.0.5.0.QDIMIXM ), and my max brightness appears to be significantly dimmer. Is anybody else having this problem? There is a possibility that it's a result of my screen cracking (it broke the same day I got the update), but I also don't see much difference between around 60% and 100%. I have a new screen coming in tomorrow, so I'll test that, but otherwise I wanted to know if there were any software problems.
Ni...brightness is the same for me..or atleast it is not noticable fot me
no problem for me
Brightness seems fine here
It's possible to overclock some monitors, and I have seen that it is possible to overclock some phone screens, so would it be possible to overclock the 4a 5g screen? Where would you even begin to do it? If it is possible to get it near 90hz would there be any long term damage?

i was wondering the samething
Not an expert or anything but IIRC the Pixel 5 has a different screen type altogether which allows it to get to 90Hz compared to the P4a 5G
No idea.
Most phones use a MIPI-DSI-2 interface the display. MIPI DSI is a high speed low-voltage differential signaling (LVDS) connection serial interface. It allows the SoC to have a high bandwidth simplex (one way) communication to the display and write to registers within the display. The maximum refresh rate of a mobile display will be limited by one or more of the following:
* maximum throughput of the SoC
* maximum throughput of the display
* number of lanes used (1, 2, or 4).
* greatest common supported "mode" between SoC and display, and hardware connection.
You can easily calculate how much throughput you need to run a specific framerate and resolution, multiply the resolution, framerate ,and color depth (usually 8 bits per color channel, 3 color channels. 2560*1080*90*3 = about 0.75GB/s (gigabytes per second). as opposed to 500Mbps.
You will need to increase the number of lanes or the clock rate. If this phone happens to have all 4 pairs hooked up but is running only 2 of the pairs, and both the screen and SoC have a common supported resolution and framerate that is higher than what you got, then sure! But I really doubt this is the case. Running the clock a little bit faster might be possible at the cost of power consumption but it will more than likely result in bit errors, corruption of the display contents, crashing/hanging, who knows.
Hi all. Sorry for my bad english.
I buy xiaomi mi 11 in my country.
But this screen brigthnes not high.
I turn of auto brightness, no any intelligent mode.
But on full screen brightness level, my old phone htc u11 and my wife phone s9+(exynos) more brighter than mi 11.
Why? Everyone in youtube, every web site say/write this phone typcal 700 nit, peek 1500 nits"
.
I can't compare with the models you refer, however, comparing to my old Oneplus 5 and my company Samsung A42, the Mi 11 does a good job.
peak (highest) brightness is only reached in Auto brightness mode and when under strong light

I try too auto mode. And i try under direct sunlight. Not change. Same result.. :/
Most of your know about this problem. People complaining about phone heating, phone shuts down in the middle of gaming, heating while gaming with 90hz in all forums. But no one come up with the solution and Some even told us to send the phone to get serviced [yeah, but even then the service center will say that it is motherboard fault, which is the costliest replacement of all around 25k INR]
[NOTE: I want this to be heard by ASUS to release software update. If you are a moderator of any Asus forum or who could contact ASUS dev, share this thread with them]
First and foremost we have to understand what is causing the problem. And everyone who is facing the problem knows Its the Temperature causing the shutdown. But ASUS never implemented any Warnings to to the UI, instead they give active cooler to 256+ GB version, while leaving 128 GB owners stranded. I faced the shut down problem when updating to A10 around a year back.
Every time when I game outdoor on warm condition (around 30 degrees) and After few months of updates, it started to shut down very frequently. So I switched back and forth to custom ROMs and even to stock A9s.
Faced the worst embarrassment "Gaming phone shuts down in front of cousins who were playing in budget phone"
Finally my Gaming phone become a phone which cant game anymore.
Finding the real Problem:
After researching about android thermals and I even tried to stop the shutdown from happening to my device. But I failed and my device successfully shuts down when there is a chance.
I switched to custom rom and installed GCAM. On taking few photos, my phone died. After restarting and enabling the CPU overlay which shown the temperature and clock speed of CPU. Opened GCAM and took some photos the temperature rose from 40-65 degrees in an instant and it died and I noted all the CPU cores are ran at max clockspeed.
So, I switched back to stock rom, used Armoury crate to limit and limited the CPU clock speed of GCAM, Again same result phone died (like the custom rom Armoury crate displayed the max clock speed of 2.96 Ghz, though the app was being set to use lower clock of 1.92 Ghz)
After using and failing to limit CPU clock using kernels, It was conclusive that the temperature is not causing the issue, "NO_THROTTLING" of CPU does.
During heavy load on CPU like gaming or benchmarking, all CPU cores will run at high clock speed, which increases the temperature of CPU. To counterfeit this, the system applies slightly lower max clock speed to all its cores, makes the CPU to run at slightly lower clock speed. As the temperature increases the max clock speed will get reduced till it can no longer produces heat (auto cooldown) on doing work. Same applies for GPU. This is called throttling.
What will happen, when throttling doesn't happen? All CPU and GPU cores run at max speed which increase the temperature, when there is nothing to stop the rising temperature. The temperature rises further [A10's thermal management kicks in] and shuts the device.
During charging, the CPU temperature will be higher due to battery dissipating the heat, so when there is even slight load on CPU (background activities like downloading) rapid rise in temperature even for few milliseconds kills device.
Maybe none of the testing devices have this problem & none of the developer devices have this problem, but this problem does exist and I'm asking ASUS to release the patch for devices which lacks controlling CPU clock speed via Armoury create, and fix the device which doesn't throttle (thermal engine)

Temporary Solution: Manually down clock the CPU and GPU
After so many failed attempt to apply lower clock to CPU, I found the location where the max clock speed file was located.
[I modified the file and put together in tasker (paid app to automate things) found my CPU finally throttled again]
I shared the values taken from asus thermal management applied those values and uploaded it.
Be careful, This might brick your device if used improperly, if that happens you might need to flash raw image so backup anything important. Don't point me the finger afterwards. If you are okay with that lets proceed.
We Need root access and root browser. If you have root access open any root browser and Extract the attached zip file
It has two folders and some files. CPU Reading folder has all the CPU max clock speed you can use to apply lower clock.
the folder contains 9 digit number like 295241178
First 3 number denotes max clock speed of Prime core i.e., 2.96Ghz
Next 3 numbers denotes max clock speed of Big core i.e., 2.4Ghz
Last 3 number denotes max clock speed of little core i.e., 1.78Ghz
for GPU First 3 number is the MHz of max clock (6750 is 675 MHz)
Select the clock speed you need
(lower number = lower clock speed = low performance = less heating
Higher number = high clock speed = better performance = more heating)
CPU has 9 different clock speed littleBigPrime combos
Gpu has 5 different combos
Applying clock speed
Replace the CPU file cpu_max_freq to the folder /sys/module/msm_performance/parameters
Replace the Gpu file max_gpuclk value to the folder /sys/devices/platform/soc/2c00000.qcom,kgsl-3d0/kgsl/kgsl-3d0
Replace those files and see if your device shuts down on gaming, if it does choose the lower value and repeat the process.
Everything should work properly now. It might not be great solution but it will prevent shutdown.

Im creating an app to solve this, which is in progress. Will update once everything is done.
por favor, preciso deste aplicatirvo!

Are you done making the app, cuz i really need it rn
its power ic related issue. throttling app is reducing the performance
