Weak signal issue in ZenFone Max (ZC550KL)

Hi,

Facing weak/ No signals many times in my ZenFone Max (ZC550KL). Issue started after updating to version WW 8939_V13.8.26.63. Even tthough Asus has given update version WW 8939-13.8.26.80 to rectify signal issue bug, still issue exists.

At a location where other mobiles are getting best 3G/4G signals, I m getting weak/ No signals in Zenfone max.

Planning to sell my phone now as not getting any solution from Asus.

Same issue here,, Having really low weak network signal issue,, nil NO to 3 tower bars fluctuate on my 8916 max zc550kl since upgraded to marshmallow,, tested with different providers like idea, BSNL, Vodafone SIM cards NO luck!! I get stable 3 Network bar on my Lenovo same location all SIMS so ASUS not cool,, expecting some patch or fix soon possible!

I had same issue now my other zenfone max doesnt have any signal at all. Os there any update or work around to fix this?

I didnt find any...Asus is pathetic...
