After using a Nokia Lumia 630 I decided to upgrade to a Lumia 925 ( unlocked ) . Over all I am happy with its performance apart from one annoying issue. I have searched and found many comments on the '' Grip of Death '' and my new 925 has this issue .
The photographs show , the current situation
I have tried the following , but the issue is still the same .
1. Using different SIM's using different carriers with different band frequencies
2. Soft reset the phone
3. Using the phone is several different geographical locations
4. Turning Airplane mode off / on
When physically holding the phone the over all quality of making and receiving calls deteraiates ( no matter how / where I hold the phone )
When the phone is not being physically held , and the calls are answered on the speaker , the over all quality is good .
When I first received the phone it was running 8.0 , but I never used the phone with a SIM card inserted, so I do not know if the same loss of signal issue was there , I updated the phone to 8.1 and then inserted a SIM .
Windows Phone 8.1
OS version 8.10.12393.890
Firmware revision number 3051.50009.1424.0001
Hardware revision number 0.5.0.1
Radio software version 3.2.04059.1
My Nokia Lumia 630 does not have this problem , using the same SIM's
Any thoughts / suggestions / comments on my current 925 problem , most welcome
As I live in Thailand the phone is unlocked and I use pre paid SIM cards , every SIM card from different providers and different radio bands , ive tried still results in the same outcome .
Hi adrianhughes , thanks for the comment
The phone is only a few days old and is un marked , Ive tried several different SIM's in the SIM tray and can't see an obvious problem, It took me 4 hours to update the phone from 8.0 to 8.1 ( via my wifi ) so if I do a hard re set would I loose the update 8.1 ? ,
Nokia care here in Thailand is not known for its customer service and is not normally a pleasant experience , and I think all I will be told is , the problem is to do with the SIM card provider and the phone is Ok .
As the problem is only evident while physically touching the phone , I'm hoping that the phone case ive ordered may to some degree fix this annoying problem , if I hold the phone with a towel I can use the phone and theres no loss of signal strength bars .
I researched this phone before buying ( phone reviews ) and never saw the '' Grip of Death '' mentioned , my mistake in not doing more research .
Ive been trying out a few more things with regard to the position of my hand on the phone and how the different hand positions affect the phones signal .
It seems that if I hold the phone and my hand touches the bottom right hand corner ( my normal hand position when using the phone ) the signal quickly reduces
Holding the phone just by its sides and top and bottom seems not to affect the signal strength
The SIM cards ive tried in the phone are
1. 3G - 850mhz
2. 3G - 2100mhz
and they all produced the same results
There is currently no 4G in my area
To day ive ventured into the nearest city and the phones signal seemed to widely fluctuate and still have the same '' Grip of death '' problem .
one interesting item I came across is this ..
Avoid touching the antenna area while the antenna is in use. Contact with antennas affects the communication quality and may reduce battery life due to higher power level during operation.
I'm still confused why only some Lumia 925's have this '' Grip of Death '' problem and many don't ?
Heres a video of my brand new Nokia Lumia 925 and the Grip of Death
Any one have the same problem
