Hello everyone ,
I bought a samsumg galaxy i9295 second hand a month ago with no warranty and i have very bad signal almost all of the time even on 2g , but in very rare moments , like 2 times in a month the signal is how it should be ,but it reverse back to bad in some time , i disassembled the phone , it has no water damage or something , i tried to heat the motherboard with a hairdryer , i reflashed the phone rom and modem , repartition , but in vain.
The ussualy signal that i get is 85 dBm 14 ASU on 2g and 103 dBM 6 ASU on 3G , but in the moments when it get back to normal it have around 69 dBM 22 ASU on 2G and 77 dBm 18 asu on 3g , same as the other phones , but sadly that are very rare moments when i get this signal with this phone , and the phone is not usable in a place with middle or bad coverage , like in a elevator or in a country zone , it have even no emergency signal.
And another thing that i observed is that the wi-fi does not work if i have less than 3 lines at wi-fi signal , if i have less it no transmit data or is extremely slow, and the speed is decreasing drastically on 3 lines , only on 4 lines ( max ) it runs how it should.
What is the problem and how can i resolve it ? I think it has a faulty power amplifier IC , but i am not sure.
It seems that the problem was the motherboard , probably that power amplifier IC or another component . After I put the motherboard in kitchen oven for about 10 minutes coveret in aluminium foil without that part with power amplifier IC , and after that the phone get the best singnal that it ever had with this phone , now i get 69 dBm 22 ASU on 3g , before that i coudn't get this singnal neither on 2g , i hope this fix will last some time , and i'm upset that i wasn't tried this method earlier , now i wait for the kitkat update and this phone will be perfect to me.
So if anyone have problems with this phone or another one that looks like be from PCB i highly recomand this method , to pot the motherboard in a oven for 10 at 100 - 200 degree C maximum for arund 10 minutes covered in aluminium foil.

Hi,yesterday during a phone call,my kaiser switch off alone,the right led became red and the battery became very very hot . I remove it quickly but too late ! I test after my phone with another battery but nothing,my kaiser is really dead.I've got this pda since december and i think problems will arrive soon on this model.Everybody knows the problem with battery drain,for me it's a latent defect of manufacturing ... Of course i'll get a new one by Orange but it'll not resolve the problem ( remember the problem on the prophet with the speaker .... ) .
Did you try possible solution B in this post?

Thanks,i 'll try now
i use an extended battery(3000mah) and it consistently stats at 75 degrees,my stock battery which i only use for backup always gets hot therefore i use it sparingly
Hello everybody,i've receive a new one by Orange,but my Kaiser doesn't recognize my Sim card ( USIM 2006 ) . I've phoned to Orange and they said me to go in Orange shop to change the sim because they have new generation Sim card ,special for 3G,and better network reception.Since i have this new sim card the battery consumes less energy than before ( same thing,bluetooth,wifi,internet ) .I gained 25 % of autonomy in more with this new Usim card ...
Hello everybody
I experienced nothing wrong at all with my SGS, but, when I was checking here and there in my phone I noticed that Time without signal = 100% ckecked it many times, restarted, and still, always 100% but nothing is really wrong with the phone, I call receive calls, sms, everything is fine, also battery is fine, signal strenth is five bars -81 dBm, 16 asu, well, this is however only happens in my second home, in my other home, it never gets higher than 10% without signal.
I just wanted to ask if there's any explanation for this
what?
How do you mean "Time without signal = 100%"?
The term when u have not GSM signal or it in airplane mode or what?
no sense
Actually, it makes sense
go to settings => about phone => Battery Use => Cell Standby
and check it, there's "time without signal" it indicates the percentage of time ur phone spent without signal, not because it's in airplane mode, not because it's off, but because there's no coverage
well, in my case, coverage is almost perfect, and still time without signal is 100%
On all the previous roms GB and ICS , i face the problem of signal drop atleast once everyday. The only wayout to getback the signal was to pull the battery out and again reboot. Now on CM 10 still the same prob exists but its better as the signal drops within a gap of 2-3 days and the simple reboot restores it back instead of pulling battery. I hope from the great expertise here to solve with my this issue. Thanking you in anticipation.
Anybody else have issues with the time without a signal stat under the Cell Standby in Power menu? Mine is consistently over 80 to 90 percent and I definitely am not without signal near that much. I have signal alll the time and never miss calls or have problems with data connectivity.
Is there really no one else out there seeing this?
Hi Everybody,
After dropping Mi 5 in water. I turned it off, and wait to dry (Putting it on RIce).
After using it for 2 days , the signals drops down (No signal) and then On, then OFF,
after using *#*#4636*#*# I check the phone information 1 and it can read the provider name but no signals.
If I turned it On, the signal is On for a while.
Any Ideas, which part I must clean or change.
Thx....
