So when im making a call my network falls back onto hspa(i know this part is normal cause at&t hasnt deployed VoLTE yet) but when i end the call i have 2-3 bars of service(this is normal) and when it switches back to lte it shoots up to 4-5 the falls down to 3-4. Is this cause of the lower frequency of the lte.? Is so then howcome it doesnt stay at 4-5 bars instead of 3.? Im not complaining or anything im just wondering.
