Help.To improve the signal to the DHD? - Desire HD Q&A, Help & Troubleshooting

I have a problem with the signal on your phone. very bad signal and large distortions in the interview. use a custom rom and I did everything that the author recommended but still remained a problem. whether someone can recommend a solution?

Try flashing a different radio, bear in mind it's signal quality (i.e can you make an receive calls) you need to monitor as the way signal strength is displayed varies with some roms

[Q] Sporadic GSM signal loss on Froyo [RESOLVED - SIM HW defect]

My phone loses signal often without any obvious reason - i.e. I've placed it on a table where the coverage is 100% and just leave it like this, but suddenly there's no signal at all. Usually in a while the connectivity is restored, but sometimes it just gets stuck without signal (installed "No signal alert" to monitor it).
I'm in Bulgaria, so there should be no problems with the UK release. I tried with 3.4.3-11 and 3.4.2-155, loosing signal on both. I just downgraded to 3.4.2-145 and the signal is stable for now...
For the record, I tested it with "clean" install - wiped, then flashed the SBF - no root, no clockwork recovery, no custom ROM, no apps...and the phone keeps loosing signal pretty often.
Anyone else noticed such behavior?
Hmm, I'm loosing signal with 3.4.2-145 as well...I'll try with different operator to see if there's difference. The other option is to downgrade to Eclair - which I guess is not an option anymore after flashing Froyo...
I'm currently using the 3.42.155 and haven't really experienced signal losses. Could it be that you must get your hardware checked? I hope you solve it soon! Goodluck!
3g and Voice calls are related, when you receive a voice call 3g is dropped, and when you hang up the phone its resumed, but if you have the wrong baseband it could happen the opposite, signal reception drops when 3g is transmiting/receiving.
This may be your case,
To the point Bad 3g speed / bad signal / drops in signal / drops in 3g, all is repaired just changing the baseband.

Sorry I left the thread without update - it turned out the SIM got defective, it just coincided with the Froyo upgrade and mislead this is the cause. After I downgraded to 2.1 it kept loosing coverage, than I moved the SIM to an old Sony Ericsson and I got "SIM Inactive" error...I don't get it why Android/Motorola can't distinguish such hardware defects...
not sure if it's your SIM, but when i was on 3.4.2-145, i also have this same problem. Had a friend with a Nokia but same operator, had 100% coverage and my phone with EMERGENCY CALL only. But it comes back in a while or so. Not sure if it's the ROM or not, but now with LiquidArc (with 3.4.3-11), signal seems to be very good, or at least on par with the dumb-phones

[Q] Radio question.

Searching did not reveal the answer.
Before I rooted (2.2 and radio not known) I would have full strength anywhere in the house with WIFI. After rooting and installing CM7 my signal is weaker.
Installed 2.15.10.07.07 with no improvement or with 2.15.00.05.2 (current)
WiFi scanning in areas I used to receive service fails to obtain them.
3G seems somewhat weaker but that is only a guess. GPS is good.
Advice?
(or after rooting it is really now telling me the truth)
Wifi has nothing to do with the radio. Not sure what your issue is caused by though. Wifi bars may visualy change at different percents in different roms like battery mods do.

2G(GSM) signal loss in rooted 4.0.4

Hi,
My signal reception is not always great. Sometimes i also have the issue of having no reception untill i unlock my screen, but thats not always the case, sometimes i have to reboot the phone to get my signal back but this not always work. The signal loss occurs even when i'm asleep and the phone is on my nightstand.(i've seen this in the battery history). Battery drainage is not greater when there's no signal. Also when i make calls i and sometimes the other person hear loud noises(peeping). Also my signal bar show full bars and when i try to make a call this doesn't work because when after a while trying to make the call, the bars drop to maybe 1 or even no bars.
The problem with high pitched noises while making calls i've had from the beginning, in GB. Losing signal reception i've had since i 've rooted ICS 4.0.3(one-click doomlord). under 4.0.3 i've flashed the .72 baseband but that didn't helped. Now recently i've did a factory reset + flashed a generic 4.0.4 and rooted it, because 4.0.4 isn't yet released in Belgium. under root I removed bloatware, but didn't remove critical apk's.
In the menu with available network providers my operator/provider has only 2G, i've choosen the automatic connection instead of manual, only in big cities 3G appears in the menu, dunno if this is relevant.
My Sim is maybe 3 years old.
Any suggestions?
Thanks

I do recommend buying a very cheap signal booster.
It's like a bumper sticker and placed where the antenna.
The signal problems rarely belong to the cell, in most cases within a few base stations belonging to the company in relation to users.
I hope I have helped.
best regards

[Q] F240l Signal Issue

I have purchase F240l from online store but i have serious signal reception issues with this mobile.
1- In outdoor Network reception is around 5-10 dbm less than other mobiles. But the real problem comes when i am in low signal areas. This phone will disconnect all of sudden after -95dbm. while other mobiles are still locked to network.
2- The wifi reception is poor as compared to other phones.
3- The GPS never locks. in GPS test it shows 28 satellites in view as soon as GPS test is started but actually all signals remain at zero and in view satellites also remain to zero.
I want to know if this problem is related to hardware or software.
Also if you guys can suggest some solution to this problem from your experience it will be very helpful.
Note: I have reflashed stock jellybean and kitkat roms by lg flash tool but there is no change in situation.
Replace the build.prop

You should try this Method.
This might solve your problem. You should backup your original build.prop in case things goes wrong, also make a Nandroid backup.
Btw it didn't work for me actually 'cause I had other radio issues with my phone.
All the credit goes to Akhtar Ali Jatt... Thanks him if it works.
I was already on custom build.prop to get rid of the Korean rom problems.
Yesterday i also installed Sphinx 3.0 which is supposed to have better signal strength.
But all of this did not work.
I want to know if other f240l users have same problem because it is not optimized for international use.
Or this problem is specific for my phone.
For hardware issue, i improved the antenna connections with pcb but still no change.

Many users have the same problem so there's nothing you can do to get better wifi signal.
Ps: my F240L is also has very weak wifi signal.
Any news about this issue? I have F240L with weak WIFI and GSM signal.

Poor Indoor reception -- Official OOS 5.0.4

i am facing poor network reception issues on my OP5T, OOS 5.0.4 , Rooted with Magisk.
Issue is when i am inside any building , be it any office or home it does not matter. Signal shows 3-4 bars but the voice keep breaking.If i go out in the open it works and no issues at all. This is not a Provider issue, i have Airtel, Idea,Vodafone and Jio sims and all behave the same way.
I have done a Factory reset, deleted all data and did a fresh install of the OS but still the issue persists.
Can some one tell if there is a custom rom that will resolve this issue or if there is any other tweak to increase indoor network reception?
I am based in Hyderabad, india.
Appreciate if experts provide any insight .
I expierence the same even with 4 bars reception is horrible not sure if there is any way to fix this
Appreciate Any help experts.
This is becoming a major problem now
