LTE weak signal

pbak

Hello everyone, i am a new happy TOUCH user.
First thing i've noticed is very weak 4g signal, when i swap my sim card to a Samsung Galaxy grand Prime i've got 4 bars on 4G but when I switch back to Umi Touch the signal on 4G is only when I'm near the windows in the center of the room the signal is switched back to 3G, whereas on same sim, same network diffrent phone the signal is okay.
UMI support can You help with this?

\n\nHi,
Thanks for the answer. Yes i have updated to V3.03-20160409. I'm from Poland my GSM network is Orange. I didn't test the lte before the update. But in the update description it's written:
"The upgrade number UMITOUCH.V3.03_20160409 brings us:
1 Optimize battery management software to improve the durability of the battery. Take you to experience the power of 4000 mAh, 24 hours 4G browsing, 60 hours 2G       call time, 92 hours music playback, 15 days standby time."
Is it possible that in the update You have decreased the RX/TX power so the battery last longer but the signal is lower?
Another thing that i've noticed is that WiFi signal is also low (both 2.4Ghz ang 5Ghz).
On needroom someone has portet cwm recovery for this phone http://www.needrom.com/download/cwm-6-0-5-1-2/ so maybe we will see cyanogenMOD for this phone soon...

I have the same problem, outside 4g is quite good, inside is poor and switch all time 3g/4g. I have noticed that outside too 4g switch all time.  Maybe needs a big update.

Today arrived FOTA V3.03-20160415_170010 at my UMI Touch,
but I still have a weak 3G (I don´t have 4G!!!) Signal indoor down to E. With a Samsung J5 in the same network/SIM-card I still have all the Time 3G at the same position!!!
The same is with the weak wifi signal...at the Samsung J5 no problem to watch youtube with 720p at the second floor, with the UMI touch there are many interruptions :-(
