Review Fixed the terrible PH-1 LTE reception with a $15 AliExpress frame. It now almost matches a Huawei P50! (Data inside)
Hey everyone,
Like many of you, I've been struggling with the infamous LTE reception on my PH-1. The ceramic back and titanium frame act like a Faraday cage, which is a nightmare for me since I work in a huge metallic warehouse.
I'm running LineageOS 22.2 (Android 15) and decided to try an experiment. I bought a replacement frame on AliExpress (around $15 with shipping). Instead of ceramic/titanium, this frame is made of a plastic inner shell, an aluminum outer frame, and a glass back cover.
My theory was that glass and plastic are much more transparent to radio waves, allowing the antennas to "breathe."
The Test (Same location, same cell tower):
I used NetMonster to measure the signal before and after the swap, and I also compared it to my Huawei P50 (which is known for having excellent antennas).
Original PH-1 Frame (Ceramic/Titanium):
· RSRP: -111 dBm
· SNR: 11 dB
· Network: 4G only (LTE 700 MHz)
2. PH-1 with the new Frame (Glass/Aluminum):
· RSRP: -108 dBm (3 dBm gain)
· SNR: 10 dB
· Network: 4G+ (LTE-A 700 + 1800 MHz)!
3. The Ultimate Benchmark: Huawei P50 (Same exact spot):
· Main Band RSRP: -112 dBm (LTE 1800)
· Secondary Band RSRP: -104 dBm (LTE 800)
· SNR: 13 dB
The Real Victory:
A 3 dBm gain might not sound like much, but look at the numbers. With the original ceramic frame, the signal was so weak that the phone couldn't even hold a single band. With the new frame, the signal is strong enough for the modem to actually perform Carrier Aggregation (4G+).
Even more impressive: the modified Essential Phone actually gets a slightly stronger raw signal (RSRP -108 dBm) on its main band than the Huawei P50 (-112 dBm). The P50 still wins on signal quality (higher SNR of 13 dB vs 10 dB), meaning it handles interference better, but the PH-1 is now in the same league!
If you have an old PH-1 and you're tired of the poor reception, I highly recommend trying this $15 mod. It won't make it a modern flagship, but it definitely fixes the "marginal" antenna performance we've all been dealing with.
good day all😀
