[Sprint HTC EVO 4G LTE] evoltesj:
Hi all. This is my first post and would like to thank the many posters and helpful threads I've read while going through my many previous phones.

After hours and hours of trying to figure out why I've been having Wifi issues, I came across a thread on XDA that helped me find a couple of simple fixes. I had to rule out the issue being with my Wifi router since all of my other electronic devices that used Wifi all worked. It had to be the phone. That and the latest software update never fixed the issue.

First off, a big Thank You to "bigoliver" across the pond who posted the :"Hardware Fault, Wifi Antenna Fault" thread in the HTC One X forum. I'll thank him here since I could not find the "thank you" button on the thread. Sorry, still a newbie.

Anyhow, after reading the thread and follwing the many helpful links in the post, I figure the probelm could be the same seeing how the Sprint version was not that mcuh different other than the Sprint only changes.

After performing the "squeeze test" as noted in the One X thread and Youtube video above, I noticed the same issue with the EVO LTE. Seems like the springs for the Wifi and BT antennas were good or enough contact with the antenna on the inside of the back case. This can be done with the Wifi Analyxer app. by simply putting pressure on the screen and back cover between the camera and volume rockers, you would notice the Wifi signal increase or decrease as your remove pressure in that area. This is where the antenna springs make conact with the antenna just inside the back cover.

The few video's I found on Youtube showed a few ways to fix the issue. One was having to solder a few contact to the Wifi and BT antenna springs. This seemed a bit dangerous since the user had to take apart the screen to get access to the spring location and back cover. Seeing how the Sprint version had the simple back cover that allowed access to the antenna springs, I figured I give it a try without soldering.

The picture above shows the EVO LTE front facing down with teh back cover off. With the phone facing down, you will see the two antenna springs pointing to the left by the volume rockers and just above the kickstand. If you look at the inside of the back cover, you will see the yellow antennas. If you align the cover as if your were putting the cover back, you will see the two antenna contact points. This is where the Wifi and BT antenna contacts are found.

All that I had to do was pretty simple. I took a tiny flat head screw driver to gently lift the two antenna springs up. Just enough to give a better contact to the antenna with the cover closed.

Once the back cover was back in place, the Wifi analyzer showed the Wifi signal to immediately increase. The Wifi signal was as strong if not stronger that my previous Evo 3D. I even noticed Wifi hot spots around me that I never saw before. This also helped the BT seing how the antennas are located at the same spot.

The other simple fix I found above seemed a bit tacky but worked. The user placed a small coin underneath the phone cover in the area where the the springs contacted the antenna on the back cover. I tried this also and it worked. Just didn't dig the sight of the coin beneath the cover.

Seeing how this helped my Wifi issue, I figured it would help others having the same issues.

After reading the posting rules, I'd looked for a simliar thread before I posted. All other the Evo 4G LTE forum all listed questions but not a fix.

Hope this is helpful to some one.

Thanks.
