Signal issues also with the M vs. my Bionic
I'm having 4G issues with my dad's new M also. His phone seems to go on 4G for about 2 seconds when you turn the phone on, and then goes right to 3G. I did some tests with my Bionic and his M side by side. My phone always shows 4G LTE here at home, and I get 1 or 2 bars. His is always on 3G. Bionic says -87 dbm 0 asu. RAZR M says 1x -90 dbm, 3G -88 dbm. Turned off wifi on both for the heck of it....Bionic said -94 dbm 0 asu, RAZR M said 1x -88 dbm, 3G -89 dbm. I then disabled LTE on my Bionic, got -88 dbm, 0 asu. RAZR M said 1x -92 dbm, 3G -88 dbm.
I downloaded the speedtest.net app. Bionic took about 5 seconds on 4G, RAZR M took 1 min. 20 seconds on 3G. I ran tests on both, sitting next to each other 2 times, 1st with data on, wifi off -
Bionic - Ping 360 ms, 3427 kbps down, 705 kbps up. Ping 247ms, 3096 kbps down, 491 kbps up
RAZR M - Ping 131 ms, 159 kbps down, 385 kbps up. Ping 124ms, 581 kbps down, 221 kbps up
Then I did the test with the phones next to each other, using wifi instead of data -
Bionic - Ping 63 ms, 9172 kbps down, 3338 kbps up. Ping 46 ms, 12327 kbps down, 2391 kbps up
RAZR M - Ping 39 ms, 3504 kbps down, 2066 kbps up. Ping 29 ms, 2384 kbps down, 1972 kbps up
So, I'm not so jealous of my dad's M anymore, and I'm re-loving my plastic Bionic. LOL
